BenQ TK700STi vs Optoma UHD35 for 4K console gaming

If you are weighing the benq tk700sti vs optoma uhd35 gaming decision for your PS5, Xbox Series X, or Switch 2 setup, the short answer is this: pick the BenQ TK700STi when you have a small or awkward room and want a smart, short-throw 4K image with rock-solid 16ms lag at 4K/60Hz; pick the Optoma UHD35 when you have a long-throw room, prefer raw brightness for ambient-light gaming, and want true 240Hz at 1080p for esports titles where every millisecond matters. Both are single-chip 0.47" DLP 4K projectors that hit 60Hz at 3840 x 2160 with HDR10, and both land in the same price band, so the real choice comes down to throw distance, refresh rate priorities, and whether you want Android TV baked in.

Quick verdict for console gamers

The BenQ TK700STi was engineered specifically as a gaming projector, and BenQ markets it as a console-first product. Its short-throw 0.9-1.08:1 lens fills a 100-inch screen from about 6.5 feet, which is a lifesaver in apartments, dorms, and converted spare bedrooms. The Optoma UHD35 is a more conventional long-throw design that needs roughly 10.8 feet to hit the same 100-inch image, but it rewards that space requirement with extra brightness, a longer-lived lamp option, and the headline-grabbing 240Hz @ 1080p mode that turns Call of Duty, Apex Legends, or Rocket League into a butter-smooth experience that no TV-style 4K projector matched until very recently.

Below we break down each spec category the way an actual console gamer evaluates a projector, then we close with a comparison table and a long FAQ covering the variations of the benq tk700sti vs optoma uhd35 gaming question we get most often.

Picture quality at 4K/60

Both projectors use the same Texas Instruments 0.47-inch DMD chip with XPR pixel-shifting to deliver 8.3 million pixels on screen, so resolution and detail are functionally identical at viewing distances over 10 feet. Where they diverge is color and HDR processing.

The BenQ TK700STi runs BenQ's CinematicColor tuning with a claimed 96% Rec.709 coverage out of the box, and the Game mode is one of the few projector picture modes we would actually leave on for general play. Skin tones look natural, greens in Horizon Forbidden West stay believable rather than radioactive, and the HDR10 tone-mapping does a respectable job of preserving highlight detail in bright scenes from Forza Horizon 5 or Starfield.

The Optoma UHD35 leans warmer and slightly more saturated by default. Its HDR mode includes Optoma's Dynamic Black, which pumps contrast aggressively and looks great in dark dungeon scenes but can crush shadow detail if you do not dial it back. The UHD35 also peaks at roughly 3600 ANSI lumens versus the TK700STi's 3000 ANSI, which is the difference between a watchable picture in a room with a single lit lamp and a picture that holds up with the blinds partly open.

Input lag, the spec that actually matters

This is where these two projectors separate themselves from every home-theater model on the market.

• BenQ TK700STi: 16ms at 4K/60Hz, 8.3ms at 1080p/120Hz, 4ms at 1080p/240Hz
• Optoma UHD35: 16.7ms at 4K/60Hz, 8.6ms at 1080p/120Hz, 4ms at 1080p/240Hz

Those numbers are essentially tied. Both projectors will feel as responsive as a mid-tier gaming TV in 2026, and both crush every long-throw home-cinema projector at the same price. For PS5 and Xbox Series X play at 4K/60, you cannot meaningfully feel the 0.7ms gap between the two. If your console can hit 4K/120 (PS5 Pro, Series X with select titles), neither projector accepts a 4K/120 signal — both top out at 1080p/120 for high-refresh play.

Refresh rate and the 1080p/240Hz question

Optoma's headline feature is the 1080p/240Hz mode. If you primarily play competitive shooters or fighting games, 240Hz is genuinely noticeable, and Optoma was first to ship it on a sub-$2,000 projector. The TK700STi tops out at 1080p/120Hz, which is still excellent and matches what most console games actually output, but esports-focused gamers on PC will prefer the UHD35.

Most console-only owners should not let 240Hz tip the scales. The PS5 cannot output 240Hz, and Xbox Series X is also capped at 120Hz. The 240Hz mode is overwhelmingly a PC-gamer feature, even though both projectors will accept any console signal you throw at them.

Throw distance and room fit

This is the single biggest practical difference. The TK700STi is a short-throw projector, and the UHD35 is not.

• BenQ TK700STi: 0.9-1.08:1 throw ratio. A 100-inch image needs about 6.5 to 7.9 feet of distance.
• Optoma UHD35: 1.21-1.59:1 throw ratio with 1.3x zoom. A 100-inch image needs roughly 10.8 to 14.1 feet.

If you are mounting on a coffee table behind a sofa in a small living room, the TK700STi is the only sane choice. If you are ceiling-mounting in a basement with a 14-foot throw, the UHD35's longer zoom range gives you more placement flexibility and a slightly sharper edge focus, since you are not pushing the lens to its widest setting. Our projector throw distance guide walks through the math if you want to plug in your specific room dimensions before buying.

Brightness and ambient light

The UHD35's 3600 ANSI lumens versus the TK700STi's 3000 ANSI is not a huge gap on paper, but in practice the UHD35 holds up noticeably better with a window open or a hallway light on. If your gaming room doubles as a family TV room and you cannot fully blackout the space, the UHD35 is the safer pick. For dedicated dark-room setups, the TK700STi's lower output is actually preferable — it produces less eye fatigue during marathon sessions and its blacks look slightly deeper because the iris is not pushing as hard.

Neither projector competes with a real laser model in a bright room. If ambient light is a serious constraint, our roundup of best home theater projectors for bright rooms covers laser alternatives that may suit you better.

Smart features and streaming

The TK700STi ships with an Android TV dongle (the QS01) that plugs into a hidden HDMI port and gives you Netflix (via a workaround), YouTube, Disney+, Prime Video, and the Google Play Store. It is genuinely useful and removes the need for a separate streaming stick on your second HDMI input.

The UHD35 has no smart features. You will need an Apple TV, Chromecast, Fire Stick, or Roku to stream. For pure gaming this does not matter, but if the projector also serves as the household movie machine, the TK700STi is more living-room-ready out of the box.

Sound

Both projectors include a 5W mono speaker that you should ignore. Neither will satisfy a console gamer who cares about audio. Plan on a soundbar or AVR — see our guide on how to connect a soundbar to a projector for the cleanest cabling approach, especially if you want lossless audio from a 4K Blu-ray player or a PS5.

Side-by-side comparison table

Who should buy the BenQ TK700STi

BenQ TK700STi

The TK700STi is the right pick if you game primarily on console, live in a smaller space, and want a single device that handles streaming and gaming without juggling extra inputs. The short throw is genuinely transformative if you have ever struggled to place a projector — you can put it on an IKEA Lack table 7 feet from the wall and have a 100-inch image without ceiling mounts, long HDMI runs, or coffee-table awkwardness. Game mode at 16ms 4K/60 is identical in feel to a good gaming OLED, and the Android TV integration means your spouse or roommate can use it for Bake Off without you setting up a Fire Stick.

Who should buy the Optoma UHD35

Optoma UHD35

The UHD35 is the right pick if you have a dedicated long-throw room, you want maximum brightness for sports and ambient-light gaming, and you play PC esports titles where 240Hz at 1080p is a meaningful upgrade. Its picture is punchier out of the box, its zoom range is more forgiving for awkward ceiling mounts, and its lack of a smart platform is irrelevant if you already own an Apple TV or a console for streaming. For mixed-use rooms where the projector handles Sunday-afternoon football and Saturday-night Halo, the extra 600 lumens earn their keep.

What about laser alternatives?

Both of these projectors use traditional lamps, which means bulb replacement every 4-6 years of heavy use. If you would rather skip the lamp question entirely, our best laser projectors for home theater guide covers the new wave of laser DLP and tri-laser ultra-short-throw models that have started competing in this price bracket. For pure console gaming, lamp DLP still offers the lowest input lag per dollar, so a lamp model like the TK700STi or UHD35 remains the smart 2026 buy unless you specifically want zero maintenance.

Frequently Asked Questions

Which has lower input lag, the BenQ TK700STi or the Optoma UHD35?

At 4K/60Hz the TK700STi measures 16ms and the UHD35 measures 16.7ms — a 0.7ms difference that no human can feel. At 1080p/120Hz both come in around 8ms, and at 1080p/240Hz both hit 4ms. For PS5 and Xbox Series X, they are effectively tied.

Can the BenQ TK700STi or Optoma UHD35 do 4K at 120Hz for PS5 Pro?

No. Both projectors accept 4K signals only up to 60Hz. To get the high-refresh modes you must drop to 1080p — 120Hz on the TK700STi, 240Hz on the UHD35. Console games that target 4K/120 (Gears 5, Ori, Fortnite Performance) will either downscale to 4K/60 or run at 1080p/120 depending on the title's settings.

Is the Optoma UHD35 bright enough for daytime gaming with the blinds open?

With light gray ambient-light-rejecting screens it does well, but no 3600-lumen lamp DLP will look great with direct sunlight on the screen. For full daylight rooms a laser UST projector is a better choice. The UHD35 shines (literally) in rooms with controlled but not blackout lighting — overhead lights off, lamps on, blinds drawn.

Does the BenQ TK700STi support Dolby Vision or just HDR10?

The TK700STi supports HDR10 and HLG only, not Dolby Vision. The same is true of the UHD35. At this price point no DLP projector ships with Dolby Vision — that feature is reserved for select higher-end JVC and Hisense laser TVs. HDR10 still looks excellent on both projectors with PS5 and Xbox Series X HDR games.

Will I need a screen, or can I project on a white wall?

A white wall works for casual setup, but a proper screen improves gain, color accuracy, and edge sharpness noticeably — easily a 15-20% perceived quality jump. For short-throw projectors like the TK700STi a slightly textured wall will reveal more imperfections because the projection angle is steeper. If you can spend $150-300 on a fixed-frame or motorized screen, do it. For ambient-light gaming rooms an ALR screen pairs especially well with the brighter UHD35.

How long do the lamps last and how much do replacements cost?

Both projectors rate their lamps at 4,000 hours in normal mode and up to 15,000 hours in extreme eco mode. Real-world expectancy with mixed use is 5,000-7,000 hours. Replacement bulbs run $150-200. At 20 hours of gaming per week you should see 5-7 years before needing a swap.

Which is better for mixed gaming and movie use?

The TK700STi is the better all-around media projector thanks to its more accurate color tuning, Android TV integration, and forgiving short throw. The UHD35 is the better dedicated gaming projector for long rooms and bright environments. If you want one machine that does everything reasonably well, lean BenQ. If your priority is the biggest, brightest, most responsive gaming experience and you have the space, lean Optoma.

What other 4K projectors should I cross-shop?

Worth comparing in the same price band are the Epson Home Cinema 2350 (LCD, smart, lower input lag than most LCDs), the BenQ HT2060 (1080p, LED, excellent color), and the newer Hisense PX3-Pro UST for those who want a laser short-throw upgrade. Our full best 4K home theater projectors roundup covers each of these in detail and helps you weigh the lamp-vs-laser and short-throw-vs-long-throw tradeoffs against the benq tk700sti vs optoma uhd35 gaming matchup.
