You’ll find plenty of home theater projectors that can give you a cinema-quality 4K image, and another slew that have a low lag ideal for gaming. If you’re looking for a model that can do both to the same high standard, it’s likely your decision will come down to the BenQ TK700STi vs. Optoma UHD38.
It’s hard to pick a clear winner between these two projectors. In a pinch, we’d say the BenQ TK700STi is the winner for convenience and gaming performance (>>> Check on Amazon), while the picture quality of the Optoma UHD38 makes it better for purely home theater applications. Really, though, it comes down to your space and needs. Let’s take a closer look to help you make your decision.
BenQ TK700STi vs Optoma UHD38 Side by Side:
|BenQ TK700STi||Optoma UHD38|
|Brightness (Lumens)||3,000 ANSI||4,000 ANSI|
|Throw Distance||2.4' - 19.6'||4.0' - 32.7'|
|Screen size||30" - 300"||33" - 300"|
|Speakers||5.0 Watts Mono||10.0 Watts Mono|
How bright of a projector you need depends on the light level in your viewing area. For most indoor viewing areas, a brightness of around 2,500 to 3,000 lumens is ideal, preventing the picture from washing out without being so bright it hurts your eyes to watch. Spaces that are well-lit or have a lot of windows need a more powerful lamp, ideally around 3,500 lumens or higher.
The 3,000-lumen lamp of the BenQ TK700STi is right in the ideal range for most homes. For outdoor use and brighter rooms, though, the 4,000 lumens of the Optoma UHD38 will be a better choice.

The Optoma UHD38 uses a standard throw distance, meaning you’ll need a decent amount of space if you want a big screen. For a 100” image, you’ll need around 10-12 feet between the lens and screen, depending on the zoom and other settings.
The short throw distance of the BenQ TK700STi saves you some space, and gives it more versatility for smaller or oddly-shaped rooms. It can produce a 100” image with as little as 6.5 feet of distance. Depending on your space, this could mean the difference between putting the projector on a shelf or table and the hassle of mounting it on the ceiling.
