Close-up of an HDMI 2.1 port on the back panel of a gaming projector

Type “4K 120Hz gaming projector” into a search bar and you’ll get a dozen confident-sounding product pages, most of them quietly glossing over a detail that matters more than anything else on the spec sheet: whether the projector can actually display 4K resolution and a 120Hz refresh rate at the same time, on the same image. Spoiler — most can’t, and that’s not a knock on the products. It’s a real limitation of the imaging chips most of them use, and once you understand it, shopping for a gaming projector gets a lot less confusing.

This guide breaks down five projectors that gamers consistently shortlist for big-screen 4K play, what each one genuinely delivers when you connect a PS5, Xbox Series X, or gaming PC, and where the marketing claims and the lived reality start to diverge. We’ll cover input lag numbers pulled from independent testing, the HDMI 2.1 question that trips up almost everyone, and which projector actually makes sense for your specific setup — whether that’s a dedicated dark theater room or a living room you’re trying to turn into a part-time arcade.

The “4K 120Hz” Truth Most Spec Sheets Don’t Tell You

Here’s the part of the story that retail listings rarely spell out clearly: there’s a meaningful difference between a projector that accepts a 4K/120Hz signal over HDMI and one that can display it at that combined resolution and refresh rate. Almost every gaming projector released in the last few years includes an HDMI 2.1 port, and HDMI 2.1 has the 48Gbps of bandwidth needed to carry 4K video at 120 frames per second. That part is genuinely true across the board.

What happens after the signal arrives is where things get interesting. The vast majority of affordable 4K gaming projectors use a single 0.47-inch DLP chip from Texas Instruments, paired with a pixel-shifting technology (often branded XPR) that rapidly shifts a 1080p-native image four times per frame to simulate 4K resolution. That chip and its supporting electronics are fast, but not fast enough to do that shifting trick at 120 times per second while maintaining 4K resolution. So when a 4K/120Hz signal arrives, these projectors typically downconvert it to 4K/60Hz internally, and the 120Hz benefit only shows up if you drop the resolution to 1440p or 1080p.

⚠️ Reality check: If a projector’s spec sheet lists “4K/120Hz” but its imaging chip is a single 0.47-inch DLP, look closer. It almost certainly means the HDMI port accepts a 4K/120Hz signal, while the panel itself caps out at 4K/60Hz — with true 120Hz only available at 1440p or below.

This isn’t a defect or a scam — it’s a genuine engineering limitation that Texas Instruments hasn’t yet solved with a faster consumer-grade chip, and reviewers across the industry have documented it consistently. The projectors that get around this limitation use fundamentally different imaging technology: three-chip 3LCD designs (like Epson’s laser lineup) or triple-laser DLP engines paired with more capable processing (like Hisense’s flagship UST models) can genuinely process a full 4K image at 120Hz, though even there, the picture is sometimes more nuanced than the marketing copy suggests.

None of this means the budget-friendly DLP projectors are bad choices for gaming. A 1440p/120Hz or 1080p/240Hz mode with rock-bottom input lag is, for many fast-paced games, arguably a better gaming experience than 4K/60Hz with higher latency. It just means you should know what you’re actually buying before you buy it. For a broader look at how these technologies stack up outside the gaming-specific lens, our guide comparing 3LCD vs. DLP projectors covers the fundamentals in more depth.

What Actually Matters for Gaming Performance

Resolution and refresh rate get the headline treatment, but they’re only part of what makes a projector feel responsive and immersive in actual gameplay. Here’s what experienced gamers learn to prioritize, often in this order:

Input Lag: The Number That Determines Whether It Feels Responsive

Input lag measures the delay between a controller input and the corresponding action appearing onscreen. For projectors, this is typically measured at specific resolution/refresh-rate combinations, since the lag changes dramatically depending on what mode you’re running. As a rough guide: under 20 milliseconds is excellent and competitive-grade, 20 to 40ms is solidly playable for nearly everything, and beyond 50-60ms you’ll start to notice a disconnect in fast-twitch genres like fighting games or competitive shooters.

Brightness in ANSI Lumens

ANSI lumens is the standardized brightness measurement that lets you fairly compare one projector to another — it averages nine light readings across the projected image. Watch out for “LED lumens” figures on LED-based projectors, which aren’t always directly comparable to an ANSI rating and can sometimes overstate real-world brightness. For gaming specifically, more brightness matters less than for movies, since game content tends to have higher contrast and pops more even at moderate lumen levels.

HDR Support and Tone Mapping

HDR10, HDR10+, and Dolby Vision support all affect how well a projector handles bright highlights and shadow detail in modern game titles. Dynamic tone mapping (adjusting brightness scene-by-scene rather than with a single static curve) tends to produce noticeably better results in games with high-contrast lighting, like anything set at night or in space.

Screen Size and Throw Distance

This is where projectors win decisively over even the largest consumer TVs. A 100-120 inch image transforms the feel of an open-world game in a way no 65-85 inch screen can replicate. Ultra-short-throw (UST) models can hit that size from inches away from your wall, while standard-throw projectors typically need 8-15 feet of room depth depending on the lens.

Practical takeaway: If you had to rank these by importance for competitive gaming specifically, the order would be input lag first, refresh rate second, resolution third, and brightness fourth. For story-driven single-player gaming, that order often flips — resolution and HDR quality matter more than shaving a few milliseconds off input lag.

Key Specs Decoded: A Quick Glossary

Projector spec sheets are notoriously dense. Here’s a fast reference for the terms you’ll run into across this guide and most product listings.

Input Lag
Delay between controller input and onscreen response, measured in milliseconds. Lower is better. Usually listed per resolution/refresh combination.
💡
ANSI Lumens
Standardized brightness measurement, averaged across nine points on the projected image. The most reliable figure for comparing brightness across brands.
🎯
XPR / Pixel Shifting
A technique where a lower native-resolution chip rapidly shifts its image to simulate a higher resolution like 4K. Used by most affordable DLP projectors.
🌈
DCI-P3 Coverage
Percentage of the digital cinema color gamut a projector can reproduce. Higher percentages mean richer, more saturated color.
🔌
HDMI 2.1
The HDMI version with enough bandwidth (48Gbps) to carry a 4K/120Hz signal. Necessary but not sufficient for true 4K/120Hz display.
📐
Throw Ratio
The relationship between distance from the screen and image width. Lower ratios mean a bigger image from a shorter distance.

For a deeper dive into how lumens translate into real-world brightness across different room types, the guide on what ANSI lumens actually means goes further into the measurement standard and what numbers you need for different ambient light conditions.

The Top 5 Gaming Projectors for 4K and High Refresh Rates

Each entry below includes verified specs pulled from manufacturer documentation and independent review testing, along with an honest note on exactly what “4K” and “120Hz” mean for that specific model — because as established above, those two words don’t mean the same thing across every product on this list.

Genuine 4K/120Hz Signal Path
Epson Home Cinema LS11000 4K PRO-UHD Laser Projector

Epson Home Cinema LS11000

3-Chip 3LCD Laser · 2,500 ANSI Lumens · HDMI 2.1
★★★★★ The closest thing to genuine 4K/120Hz gaming on a projector

The Epson LS11000 is the rare gaming projector that can back up its 4K/120Hz claim without an asterisk. Because it uses a true 3-chip 3LCD laser engine rather than a single pixel-shifting DLP chip, it can process a full 3,840 x 2,160 image at up to 120Hz, with input lag rated below 20 milliseconds in that exact combination. Dual HDMI 2.1 inputs, each carrying the full 48Gbps of bandwidth, mean you can connect a PS5 and an Xbox Series X simultaneously and switch freely without bottlenecking either signal.

Beyond the headline gaming spec, the LS11000 is also a genuinely excellent home theater projector. Its laser light source is rated for 20,000 hours without maintenance, eliminating the recurring bulb-replacement cost of older lamp-based units, and its motorized 3-way lens with memory presets makes multi-aspect-ratio setups far easier to manage than on cheaper models. The dynamic contrast ratio exceeding 1,200,000:1 helps dark scenes in games hold detail rather than collapsing into mud, something budget DLP projectors often struggle with.

The tradeoff is straightforward: price. At roughly double the cost of the DLP options on this list, the LS11000 asks you to pay a real premium for genuine 4K/120Hz performance and superior image quality across the board. For anyone building a dedicated gaming and movie room who wants to stop worrying about asterisks on spec sheets, it’s worth the jump. If you’re weighing it directly against other premium home cinema options, the comparison piece on the Epson LS12000 vs. JVC NZ500 covers how Epson’s lineup stacks up against the competing laser ecosystem.

Pros

  • Genuine 4K/120Hz processing, not downconverted
  • Sub-20ms input lag at full 4K/120Hz
  • Dual full-bandwidth HDMI 2.1 inputs
  • 20,000-hour maintenance-free laser source
  • Excellent contrast for dark game scenes

Cons

  • Significantly pricier than DLP alternatives
  • No built-in speakers

Designed for Xbox · UST
Hisense PX3-PRO Triple Laser Ultra Short Throw Projector

Hisense PX3-PRO TriChroma Laser UST

Triple-Laser DLP UST · 3,000 ANSI Lumens · 2x HDMI 2.1
★★★★★ Officially “Designed for Xbox” with the best near-wall placement

The PX3-PRO is the only ultra-short-throw projector on this list, meaning it sits just inches from your wall or screen and throws a 80-150 inch image without any ceiling mounting or long cable runs — a huge practical advantage for anyone converting a living room rather than building a dedicated theater. It earned official “Designed for Xbox” certification, and its two full-bandwidth HDMI 2.1 ports genuinely accept and process a 4K/120Hz signal from current consoles, with independent testing measuring around 14ms of input lag at that combination.

Worth noting honestly: like other DLP-based projectors, the PX3-PRO’s 0.47-inch chip is native 1080p with pixel-shifting to reach 4K, so some of the same downconversion nuances that affect budget DLP units can apply here too, though Hisense’s processing and the wider HDMI 2.1 bandwidth give it markedly better real-world gaming numbers than cheaper DLP competitors. Its triple-laser RGB light engine is the standout feature beyond gaming specs — it produces 110% of the BT.2020 color gamut, among the widest color reproduction of any projector at this price, with a 50-watt built-in Harman Kardon sound system that genuinely competes with standalone soundbars.

For households where a ceiling-mounted projector simply isn’t practical, this is one of the strongest gaming-capable options available. Our dedicated guide to best ultra-short-throw projectors covers more UST options if placement flexibility is your top priority.

Pros

  • Officially Designed for Xbox certified
  • Ultra-short-throw — no ceiling mount needed
  • ~14ms input lag at 4K/120Hz in testing
  • Excellent built-in 50W Harman Kardon audio
  • 110% BT.2020 color gamut

Cons

  • Requires a UST-compatible screen for best results
  • DLP chip means some 4K/120Hz processing nuance
  • No 1440p/120Hz mode unlike standard-throw rivals

BenQ X3100i 4K HDR Console Gaming Projector

BenQ X3100i Flagship Console Gaming Projector

4LED DLP · 3,300 ANSI Lumens · 3x HDMI 2.0b
★★★★☆ The best dedicated console gaming projector under 4K/120Hz

BenQ’s X3100i is built from the ground up as a console gaming projector, and it shows in every detail — Auto Game Mode that recognizes whether you’ve plugged in an Xbox, PlayStation, or Switch and adjusts settings automatically, an FPS crosshair overlay, and dedicated picture modes for RPGs, sports titles, and racing games. Independent testing measured input lag at roughly 17ms in 4K/60Hz, 9ms at 1440p/120Hz, and as low as 5ms at 1080p/240Hz — genuinely excellent numbers for a DLP-based projector at this price.

The honest caveat: the X3100i uses HDMI 2.0b ports rather than HDMI 2.1, which caps it at 4K/60Hz with no path to 4K/120Hz at all, console-side. If “4K 120Hz” specifically means simultaneous 4K resolution and 120Hz refresh to you, this isn’t that projector — but if you’re comfortable trading resolution for refresh rate (dropping to 1440p/120Hz for fast competitive titles), it’s one of the most thoughtfully gaming-optimized projectors available. Its 4LED light source rated for 20,000-30,000 hours and 3,300 ANSI lumens of brightness also make it a strong choice for living rooms with some ambient light.

For anyone weighing whether to go UST or standard-throw for this kind of console-focused setup, the comparison guide on UST vs. standard throw projectors can help clarify which fits your room layout better.

Pros

  • Purpose-built console gaming features (Auto Game Mode, FPS crosshair)
  • ~9ms input lag at 1440p/120Hz
  • 3,300 ANSI lumens — bright for ambient-light rooms
  • Built-in 5W TreVolo-tuned stereo speakers

Cons

  • No HDMI 2.1 — capped at 4K/60Hz, no 4K/120Hz
  • Android TV menu response can feel sluggish

ViewSonic X2-4K Designed for Xbox Gaming Projector

ViewSonic X2-4K Designed for Xbox Projector

LED DLP Short Throw · 2,900 LED Lumens · 2x HDMI 2.0
★★★★☆ The fastest-feeling budget option for Xbox-specific resolutions

ViewSonic earned the distinction of building the world’s first projector formally “Designed for Xbox,” and the X2-4K’s gaming credentials hold up under testing: 1440p/120Hz input lag measured around 9ms, 1080p/240Hz dropping to roughly 5ms with Ultra-Fast Input enabled, and 4K/60Hz coming in around 18ms. Its short-throw lens hits a 100-inch image from just 1.5 meters away, which is a meaningful space-saver if your room can’t accommodate a longer standard-throw setup.

The same honest caveat applies here as with the BenQ: HDMI 2.0 ports mean no 4K/120Hz path exists, full stop. What you get instead is a deliberately tuned sweet spot at 1440p/120Hz — ViewSonic’s own marketing leans into this combination directly rather than overselling 4K resolution at high refresh, which is a refreshingly straightforward approach compared to some competitors. The Harman Kardon speakers and Xbox controller-based CEC control (powering the projector on/off via your controller) add small but genuinely useful conveniences for console-first households.

If your gaming priorities lean toward PC and you’re deciding between a short-throw setup like this and a more flexible standard-throw lens, our guide on calculating projector throw distance walks through how to figure out what your specific room can accommodate.

Pros

  • First officially “Designed for Xbox” projector
  • Strong 1440p/120Hz and 1080p/240Hz performance
  • Short-throw lens — 100″ image from 1.5m
  • 60,000-hour rated LED light source

Cons

  • No HDMI 2.1 — no 4K/120Hz path
  • 2,000 ANSI lumens (independently measured) is modest for bright rooms

Optoma UHD55 4K Home Theater and Gaming Projector

Optoma UHD55 4K Gaming & Home Theater Projector

Lamp-Based DLP · 3,600 ANSI Lumens · 2x HDMI 2.0
★★★★☆ The brightest pick on this list, with the most all-around value

The Optoma UHD55 takes a different approach from the other gaming-first entries on this list: it’s a genuine home-theater-and-gaming hybrid, measured at 3,478 ANSI lumens in independent testing (just shy of its 3,600 rating) and offering 97% DCI-P3 color coverage — both figures that comfortably beat every other projector here on raw brightness and color volume. Its Enhanced Gaming mode brings input lag down to roughly 16.9ms at 4K/60Hz and as low as 4.3-4.4ms at 1080p/240Hz, numbers that hold up well against pricier dedicated gaming projectors.

As with the BenQ and ViewSonic, HDMI 2.0 ports mean the UHD55 has no path to 4K/120Hz — its 120Hz mode lives specifically at 1080p resolution rather than 1440p, and reviewers have noted you generally can’t have both the projector’s widest color gamut and its absolute lowest input lag active simultaneously, since the wide-gamut filter adds a touch of processing overhead. For most living rooms, this is a minor tradeoff easily managed by switching modes between movie night and competitive sessions.

Where the UHD55 pulls ahead is value: at a similar price point to the BenQ and ViewSonic, it offers meaningfully more brightness and color volume, making it the strongest pick for anyone who splits time fairly evenly between gaming and movie watching. Vertical lens shift and a 1.3x optical zoom also give it more installation flexibility than most competitors in this price bracket. If you’re trying to figure out exactly how that brightness translates to your specific room, the guide on best projectors for bright rooms has more context on lumens versus ambient light.

Pros

  • Brightest on this list — 3,478 ANSI lumens measured
  • 97% DCI-P3 color coverage
  • ~4.3ms input lag at 1080p/240Hz
  • Vertical lens shift + 1.3x optical zoom

Cons

  • No HDMI 2.1 — no 4K/120Hz path
  • Lamp-based (not laser/LED) — bulb replacement costs over time

Full Comparison: 4K Gaming Projectors Side by Side

Use this table to compare every spec that actually affects gaming performance at a glance. The “Real 120Hz Path” column is the one most listings leave out — it’s the honest answer to whether 120Hz is available at full 4K, or only at a reduced resolution.

*ViewSonic lists 2,900 LED lumens; independent ANSI lumen testing measured roughly 2,000–2,155 ANSI lumens, a reminder that LED lumens and ANSI lumens aren’t directly comparable figures.

Best Pick by Use Case

Rather than crowning one universal “best,” the right projector here really does depend on what you’re optimizing for. Here’s how we’d match each pick to a specific situation.

Use Case
Competitive / Esports Play

Optoma UHD55 or ViewSonic X2-4K — both deliver sub-5ms input lag at 1080p/240Hz, the lowest-latency mode on this list, ideal for fighting games and competitive shooters where every millisecond counts.

Use Case
Genuine 4K/120Hz Demand

Epson LS11000 — the only pick that processes full 4K resolution at 120Hz without any asterisk, ideal for anyone who specifically wants that combination for next-gen console gaming.

Use Case
Living Room, No Ceiling Mount

Hisense PX3-PRO — its ultra-short-throw design sits inches from the wall, avoiding the installation hassle of mounting hardware in a shared living space.

Use Case
Console-First Household

BenQ X3100i or ViewSonic X2-4K — both offer dedicated console-recognition features and Designed-for-Xbox-tier optimization that PC-first projectors don’t bother with.

Use Case
Mixed Movie + Gaming Use

Optoma UHD55 — the brightest, widest-color-gamut option on this list, making it the strongest all-rounder for households that aren’t gaming-only.

Use Case
Budget-Conscious First Projector

ViewSonic X2-4K — typically the most affordable of the five, with genuinely useful Xbox-specific tuning that punches above its price point.

For broader buying context: If gaming is only one part of what you want this projector to do, our complete guide to best projectors for every budget and room size takes a wider lens beyond gaming-specific priorities.

Setting Up Your Projector for the Lowest Possible Lag

Buying the right hardware is only half the equation — how you configure it matters just as much. These adjustments apply across nearly every gaming projector on the market, including all five reviewed above.

Enable the Dedicated Game Mode

Every projector on this list has a Game or Enhanced Gaming picture mode that strips out unnecessary image processing — motion smoothing, noise reduction, and color enhancement chains that add latency without meaningfully improving the picture during fast motion. Always switch to this mode before a gaming session; leaving the projector on its default Cinema or Standard mode can add anywhere from 20 to 80 milliseconds of needless lag.

Match Console Output Settings to Projector Capability

On PS5 and Xbox Series X/S, dig into the video output settings and explicitly select the resolution/refresh-rate combination your specific projector actually supports at low latency — for the BenQ, ViewSonic, and Optoma, that often means deliberately choosing 1440p/120Hz or 1080p/120Hz over 4K/60Hz for competitive titles, even though 4K is available. Letting the console auto-negotiate sometimes defaults to the highest resolution rather than the lowest latency.

Use a Short, High-Quality HDMI Cable

For any HDMI 2.1 setup carrying 4K/120Hz signals (relevant to the Epson and Hisense picks here), cable quality genuinely matters. A cheap or overly long cable can fail to maintain the full 48Gbps bandwidth, causing the connection to drop back to a lower resolution or refresh rate intermittently. Look for cables explicitly certified as “Ultra High Speed HDMI” for any 4K/120Hz setup.

Disable Frame Interpolation for Competitive Titles

Frame interpolation (sometimes called motion smoothing or MEMC) generates artificial in-between frames to make motion look smoother, but it adds processing time and therefore lag. It’s genuinely useful for movies and slower-paced games, but should be turned off entirely for anything competitive.

⚠️ Common mistake: Leaving HDR wide-color-gamut filters active during competitive play. On projectors like the Optoma UHD55, the wide-gamut filter and absolute lowest input lag mode can’t always run simultaneously — check your specific model’s documentation before assuming you have both at once.

Frequently Asked Questions

Can any projector actually display true 4K at 120Hz?

Very few. Most single-chip DLP gaming projectors — including the BenQ, ViewSonic, and Optoma reviewed above — accept a 4K signal but cap their actual onscreen refresh at 4K/60Hz, reserving genuine 120Hz for 1080p or 1440p modes. Three-chip designs like the Epson LS11000 and triple-laser UST units like the Hisense PX3-PRO are among the few consumer projectors that can process 4K at 120Hz end to end.

Why does my projector say it supports 4K 120Hz but games look the same as 60Hz?

Many projectors accept an HDMI 2.1 signal carrying 4K/120Hz metadata but internally downconvert it to 4K/60Hz before displaying, because their imaging chip (commonly a 0.47-inch DLP chip) physically can’t refresh fast enough at full 4K resolution. The HDMI port accepting the signal doesn’t guarantee the panel can actually display it at that rate.

What input lag is good enough for competitive gaming on a projector?

Under 20ms is considered excellent for competitive play, comparable to many gaming monitors. Between 20-40ms is still very playable for most game genres. Anything over 50ms becomes noticeable in fast-paced shooters or fighting games, though it’s typically fine for story-driven or turn-based titles.

Do I need HDMI 2.1 for a gaming projector?

HDMI 2.1 is necessary if you want to send a 4K/120Hz signal from a PS5, Xbox Series X, or gaming PC to the projector, since HDMI 2.0 doesn’t have the bandwidth for that combination. However, having an HDMI 2.1 port doesn’t guarantee the projector’s internal chip can actually display 4K at 120Hz — check the specific imaging technology, not just the port.

Is a gaming projector better than a gaming monitor or TV?

Projectors offer a dramatically larger image, often 100 inches or more, that no consumer monitor or affordable TV can match, which many gamers find more immersive. However, monitors and OLED TVs generally win on input lag, contrast, and color accuracy. The right choice depends on whether screen size or per-pixel responsiveness matters more to your gaming priorities.

Why do most 4K gaming projectors use DLP instead of laser or LCD?

Single-chip DLP technology, combined with pixel-shifting (XPR), is currently the most affordable way to display 4K resolution on a projector. Laser and 3-chip 3LCD designs like the Epson LS11000 can offer better color and contrast, along with genuine 4K/120Hz support, but at a significantly higher price point.

What’s the difference between ANSI lumens and LED lumens?

ANSI lumens is a standardized measurement using nine averaged readings across the projected image, making it directly comparable between projectors. LED lumens is a less standardized figure that manufacturers sometimes use for LED-based projectors, and it isn’t always directly comparable to an ANSI rating. When comparing brightness, ANSI lumens figures are more reliable.

Can I use a gaming projector in a bright room?

Brighter projectors rated 3,000+ ANSI lumens, like the Optoma UHD55 or BenQ X3100i, hold up reasonably well with some ambient light. However, all projectors perform best with at least partial light control, since a darkened room dramatically improves perceived contrast and color saturation regardless of the lumen rating.

How much screen size do I need for gaming?

A 100 to 120-inch screen is the sweet spot for most living rooms and dedicated game rooms, giving you an immersive scale without requiring you to sit unreasonably far back. Ultra-short-throw models like the Hisense PX3-PRO can hit that size from just inches away from the wall, while standard-throw projectors need more room depth.

Is laser or LED better for a gaming projector?

Both laser and LED light sources eliminate the bulb-replacement costs of traditional lamp projectors and typically last 20,000 to 60,000 hours. Laser sources generally produce richer color and higher peak brightness, which is why premium projectors like the Epson LS11000 and Hisense PX3-PRO use laser engines, while LED is common in more affordable gaming-focused models like the ViewSonic X2-4K.

Should I buy a UST or standard throw gaming projector?

Ultra-short-throw (UST) projectors like the Hisense PX3-PRO sit just inches from your wall or screen, which avoids the shadow and cable-routing problems of ceiling mounting and works well in living rooms doubling as game spaces. Standard-throw projectors like the Epson LS11000 need several feet of distance but generally offer more installation flexibility for dedicated theater rooms.

Conclusion: Pick the Spec That Matches How You Actually Game

The honest takeaway from all five of these projectors is that “4K 120Hz” isn’t a single feature you’re shopping for — it’s two separate capabilities that only a couple of products on the market currently deliver together without compromise. If full 4K resolution at 120Hz is genuinely non-negotiable for you, the Epson LS11000 and Hisense PX3-PRO are the two picks here that earn that claim honestly, with the Epson winning on raw image quality and the Hisense winning on installation flexibility as a UST model.

But if you’re willing to flex on resolution in exchange for rock-bottom input lag, the BenQ X3100i, ViewSonic X2-4K, and Optoma UHD55 all deliver genuinely excellent gaming experiences at 1080p or 1440p with refresh rates and latency numbers that rival dedicated gaming monitors — often at half the price of the laser options. None of these five are bad choices; they’re simply optimized for different priorities, and now you know exactly which tradeoff each one is actually making.

Whichever you land on, pair it with the setup adjustments covered above — dedicated game mode, matched console output settings, a properly rated HDMI cable — and you’ll get noticeably more out of any of these five than running them on default settings out of the box.
