Epson 3800 vs BenQ TK850

The sheer number of 4K projectors on the market can make choosing the right one for your home feel like an overwhelming prospect. Comparing the Epson 3800 vs BenQ TK850, their stats look very similar. Both have a bright 3,000 lumen lamp and a wide color gamut, as well as similar throw distances and image set-up features. They also sell at a similar price-point—comfortably in the mid-range and a great value for your money.

Both the Epson 3800 and the BenQ TK850 are high-quality projectors. Neither one is definitively better than the other. Instead, each is a good choice for a different kind of user. If you’re looking for the absolute best picture quality, you’ll want to get the BenQ TK850.

Ultra HD resolution is the current gold standard, and both these projectors are advertised as offering it. While it’s true they both have a sharper picture than you’ll get from full HD, though, they’re not necessarily equal in this regard.

The BenQ TK850 has a true 4K resolution, with over 8 million on-screen pixels—roughly 4 times what you’ll get from standard HD. The Epson 3800 uses a process known as pixel-shifting. It’s about twice as detailed as full HD, but only half as many pixels as you’ll get with true 4K.

Sharper resolution: BenQ TK850

Gaming Performance

The primary factor of interest to gamers is the input latency, or the delay between your input on the controller and what you see on the screen. Anything below about 60ms is fast enough for casual gaming. Professional or serious gamers will want to look for an input lag of 30ms or less.

The Epson 3800 delivers on this front. The input lag is an impressive 28ms even when you’re gaming in 4K and drops even lower if you turn off the pixel shifting. Its high video processing rate is a benefit here, as well, preventing on-screen compression artifacts that can affect your playing. This makes it much better for gaming than the BenQ TK850, which registers a latency over 80ms no matter how you adjust the picture.

Better for gaming: Epson 3800


If you’re looking for true theater sound or surround sound, you’ll need to connect external speakers to both of these projectors. For casual TV watching, though, the crispness of the dialogue is more important than a big bass or massive volume.

Both of these projectors have decent sound in that context. We found the 10w stereo speakers on the Epson 3800 slightly better in this regard, however. They put out more volume and have a better audio quality than the speakers on the TK850 (or most projector speakers, for that matter).

Epson 3800 vs BenQ TK850: Full Reviews

Epson 3800

Epson 3800The Epson 3800 performs well for both home theater use and gaming. This starts with its 3-chip design and efficient video processing. Colors are accurate and vibrant, with a wider color gamut than you’ll get from most projectors. You also won’t have to worry about annoying image issues like blocking or the rainbow effect.

For gamers, the Epson 3800 checks all the boxes. Its input lag is low, even when you’re gaming in 4K, so you don’t have to sacrifice image quality for smooth action. The impressive 12-bit processing helps here, too, reducing screen blur and other issues that could impact your play.

Now this is a hefty projector, at about 20 pounds. This isn’t much of an issue if you’re installing it permanently in one room but it does make it less portable. On the flip side of that, it’s more flexible when it comes to placement. It has a manual optical zoom and both horizontal and vertical lens shift, as well as 30° vertical keystone correction. There’s a wide range of input options, as well. For most users, getting set up is a breeze, even if you can’t center the projector exactly on the screen when you install it.


  • Supports 4K gaming with low input lag
  • 3LCD chip design produces vibrant colors with no rainbow effect
  • High contrast ratio for better black levels
  • Smooth frame transitions with real-time video processing
  • Wide range of input options supports content from more sources
  • Robust image adjustment options


  • Pixel shifting doesn’t give the same detail as true 4K
  • Bulkier unit could be more difficult to install

BenQ TK850

BENQ TK850 4k projectorWith the BenQ TK850 you’ll get a true 4K resolution—about twice the on-screen pixels of the Epson 3800 above. The lens array and visual technology employed here are all-around more sophisticated. That translates to a sharper and brighter picture, even though the lamp puts out the same amount of lumens. The BenQ TK850 is included among the best 4K projectors under 2000 dollars.

For watching movies and sports, you’d be hard-pressed to find a better projector. Dedicated viewing modes help with this, as does the automatic tone mapping and HDR-PRO support. Since it’s relatively compact and can produce a massive image, this is the best choice if you want a projector you can take outside for backyard movie nights. It’s also ideal for viewing parties since its bright lamp accommodates lights-on viewing.

The main short-falling of the BenQ TK850 is its gaming performance. It has a gaming mode but it’s functionally useless, only lowering the input lag to about 81ms. The delay is definitely noticeable, especially in fast-paced racing games or first-person shooters. Casual players of RPGs and puzzle games can make it work, but it’s definitely not what we’d call a gaming projector.


  • True 4K resolution
  • Dedicated Sport and CinemaMaster modes
  • 10-element lens array optimizes sharpness and color
  • Dynamic Iris technology improves contrast and brightness
  • Includes 1.3x zoom and lens shift for easier installation
  • Factory-calibrated color exceeds Rec. 709 spectrum
  • Compact, lightweight build


  • High input lag is unsuitable for gaming
  • On-board speakers aren’t as good
