Hey everyone, Jim here. Today I'm comparing two heavy hitters in the 4K projector world: the Benq TK850i and the Optoma UHD55. Both deliver stunning 4K UHD resolution, HDR, and gamer-friendly features. But they also have some key differences in brightness, color, and smarts.
I've spent quality time with both projectors, analyzing picture quality, gaming performance, ease of use, and more. I'll share my hands-on experiences to help you decide which one best fits your needs and budget. Let's dive in!
Benq TK850i vs Optoma UHD55: Quick Overview
I respect your time and aim to provide only the essential information, skipping the fluff.
If you're in a hurry, here's my quick take: Having tested both the Benq TK850i and Optoma UHD55, I've found they are very similar 4K projectors overall. The main differences that stood out to me are brightness, with the UHD55 pumping out 3,600 lumens vs the TK850i's 3,000, and color, with the UHD55 covering a wider DCI-P3 gamut. The TK850i has the convenience of Android TV smarts, while the UHD55 offers a lightning-quick 240Hz gaming mode.
In my opinion, you should choose the UHD55 if you want the brightest possible image, widest HDR color, and lowest input lag for gaming.

Both the Benq TK850i and Optoma UHD55 use pixel shifting to achieve 4K from a native 1080p chip, and both do it exceptionally well. I was hard-pressed to spot any resolution difference in real-world viewing. Fine details like hair, textures, and distant objects were tack-sharp on either projector.
A key difference is brightness, with the UHD55 cranking out 3,600 ANSI lumens to the TK850i's still-ample 3,000 lumens. This gives the UHD55 more pop and sizzle, especially in rooms with some ambient light. But I was quite satisfied with the TK850i's brightness for the vast majority of content.
The UHD55 flexes its muscles in contrast too, boasting a mind-boggling 1,200,000:1 dynamic ratio. This was evident in the inkier blacks and more defined shadow detail compared to the TK850i's already impressive 30,000:1. If you crave those deep, rich OLED-like black levels, point to the UHD55.
Color is another feather in the UHD55's cap, covering a wider DCI-P3 gamut than the TK850i (95% vs an estimated 85-90%). This translated to slightly more saturated, vibrant hues, especially in HDR. The TK850i is still very colorful, but the UHD55 takes it a notch above.
Speaking of HDR, both projectors support the HDR10 and HLG formats and both do an admirable job tone mapping content. I did prefer the UHD55's HDR image by a hair, with its higher peak brightness and wider color gamut affording more headroom. But the TK850i's HDR is far from shabby.
For installation, the two are evenly matched with 1.3x manual zoom and moderate lens shift (the UHD55's range is a smidge wider at +5%/-15% vs the TK850i's +10%). Keystone correction and zoom memories are available on both. I do wish Benq included motorized lens controls like some competitors, but it's not a deal breaker.
Now let's talk speed - a huge factor for gamers. The UHD55 leaves the TK850i in the dust here with an insanely low 16.9ms input lag at 4K/60Hz and a mind-boggling 4ms at 1080p/240Hz. The TK850i's 16ms at 4K/60Hz is no slouch, but it can't touch the UHD55 for those who demand the fastest possible response.
The UHD55 also has more gamer-centric features like a 21:9/32:9 aspect ratio detection for ultra-wide gaming or an integrated gaming mode with enhanced color and contrast. The TK850i is a fine gaming projector but the UHD55 is just built different in this regard.
So where does the TK850i pull ahead? Smart features. With Android TV and Google Assistant built right in, it's a more complete all-in-one entertainment hub. The UHD55 has Optoma's Marketplace for app downloads and screen mirroring, but it's not as slick or full-featured as Google's TV OS. Plus you'll need to BYO streaming stick.
Then there are things like the fan noise - a bit quieter on the TK850i in my experience - and the onboard speakers, where the UHD55's 10W mono speaker outmuscles the TK850i's 5W stereo pair. But these are secondary to picture quality in my book.
To sum up, if you're after the brightest, most colorful image, best contrast, and lowest gaming lag, the Optoma UHD55 is the clear winner. It's simply a cut above in those regards, making it a top pick for discerning cinephiles and competitive gamers. But the Benq TK850i remains an excellent 4K projector with a more well-rounded feature set, elegant Android TV integration, and stellar all-around performance. It's the better choice for folks who prize all-in-one simplicity over sheer specs.
Optoma UHD55 vs Benq TK850i: Design
Let's talk designs - hopefully your projector won't be the centerpiece of your room, but it's still nice to have gear that's functional and easy on the eyes.
Benq TK850i Design:
Optoma UHD55 Design:
The TK850i features a clean white and gray color scheme with rounded edges and an offset lens. It's not exactly compact at 13" x 8.9" x 4.3" and 9.2 lbs, but it's manageable for ceiling mounting or shelf placement. I'm a fan of the sleek lines and neutral colors.
The UHD55 goes for a more aggressive aesthetic with a black housing and sharper angles. It's a bit smaller and lighter at 12.4" x 10.6" x 4.7" and 8.2 lbs. The lens is centered on the front with large vents on either side. It definitely has more of a "gamer" vibe compared to the TK850i's living room chic.
Connectivity is solid on both, with dual HDMI ports, USB ports for power/media, optical and 3.5mm audio outputs, RS-232 for automation, and Bluetooth. The UHD55 adds a couple more HDMI 2.1 ports (one with eARC), VGA, Ethernet, and a 12V trigger. So it's a bit more equipped in the wired department.
Both include fully backlit remote controls, though I prefer the TK850i's more compact design with the dedicated Android buttons. The UHD55's remote is chunkier but does include a full numpad for direct input access.
As for fan noise, the TK850i is a bit quieter overall, particularly in its SmartEco lamp mode. The UHD55's noise is far from offensive but is noticeable in Dynamic mode. Thankfully, both projectors' fans are nearly silent in their lowest lamp settings.
All in all, the Benq TK850i has a sleeker, more living room friendly design and a slight edge in operational noise. The Optoma UHD55 is the more purposeful-looking of the two and offers a few more hardwired connection options. But from a practicality standpoint, they're evenly matched. Just pick the one that tickles your aesthetic fancy.

Next up, let's see what actual buyers have to say about their experiences with the TK850i and UHD55:
Benq TK850i Reviews:
Praises: "The picture quality and Android interface alone make it worth the price tag. The 4K is stunning and the projector upscales 1080p content wonderfully.The HDR performance is really impressive for the price. It's not OLED-level but adds a lot of depth and pop to movies and shows."
***
Drawbacks: "The speakers are pretty lackluster. They're fine for casual viewing but for a more cinematic experience, definitely plan on using a soundbar or external speakers.The fan noise is definitely noticeable in the normal lamp mode, but it's much better in Eco mode. Not a huge deal but something to keep in mind."
Optoma UHD55 Reviews:
Praises:"This projector is an absolute beast for gaming. I can't believe how responsive it feels, even at 4K. It's like playing on a massive high-end gaming monitor. The brightness and contrast are stunning. The image just pops off the screen, especially in a dark room. HDR content looks phenomenal."
***
Drawbacks:"The projector gets quite hot after a few hours of use - make sure it has plenty of ventilation. The fan noise is also more noticeable at full brightness."
"The 1.3x zoom range is a bit limited for my needs. I wish it had a bit more flexibility in throw distance for easier placement."
Overall, owners of both projectors are thrilled with their purchases, frequently citing the excellent 4K picture quality, HDR performance, and overall value. TK850i buyers love the convenience of Android TV and the projector's strong multimedia performance. UHD55 users can't stop raving about the gaming prowess, brightness, and contrast.
On the downside, the TK850i's speakers and fan noise on higher lamp modes are common complaints. Some UHD55 owners knocked the lack of streaming apps and wished for a greater zoom range. But by and large, both projectors are delivering a highly satisfying big screen experience with very few caveats.
Benq TK850i and Optoma UHD55 Alternatives
Not quite convinced by either the TK850i or UHD55? Here are a couple other projectors I'd suggest checking out:
- Epson Home Cinema 5050UB: A similarly priced 4K PRO-UHD projector with excellent out-of-box color accuracy, motorized lens, and robust 3D support.
- Benq HT3550i: A slightly lower cost 4K DLP projector from Benq with a wide color gamut, HDR-PRO tone mapping, and a compact design.
The Epson 5050UB is a strong contender if you value out-of-box accuracy, install flexibility (it has an excellent motorized 2.1x zoom and lens shift), and watching 3D movies. The pixel shifting is also remarkably fast and smooth thanks to Epson's 3LCD technology.
In the Benq family, the HT3550i is worth a look if you want similar 4K HDR performance to the TK850i but don't need the higher brightness or Android TV smarts. It's one of the most color-accurate projectors out of the box and has a very flexible zoom range and lens shift for easy placement.
Which 4K Projector Is Better, Benq TK850i or Optoma UHD55?
Alright, we've covered a lot of ground in this comparison of the Benq TK850i vs Optoma UHD55. Both are highly capable 4K projectors that deliver a huge, sharp, and dynamic picture. But as we've seen, each has its own unique strengths.
For the majority of home theater setups, I give the overall edge to the Optoma UHD55. Its higher brightness, superior contrast, wider color gamut, and lightning-fast gaming performance make it an exceptional value for the price. If you're a discerning viewer who wants the punchiest HDR and lowest input lag, it's worth the premium over the TK850i.
However, the Benq TK850i remains an outstanding projector in its own right. It may not match the UHD55's peak brightness or color coverage, but it's no slouch in picture quality. And for some buyers, the slick Android TV interface, wide app support, and voice control will more than make up for those technical differences. If you're looking for an all-in-one 4K projector that's a bit more living room-friendly, the TK850i is a fantastic pick.
As always, it really comes down to your specific needs, preferences, and budget. If you're a movie buff or competitive gamer seeking the absolute best specs, go with the Optoma UHD55. If you want a great all-around 4K projector with the convenience of built-in smarts, the Benq TK850i is a top contender. Either way, you'll be blown away by the big-screen experience.
