The TK850I uses advanced XPR pixel shifting technology to convert a 1080p resolution image into a 4k resolution on screen. The TK850I does a marvelous job projecting a high-resolution image that is also smooth and colorful. It uses a series of mirrors to switch the frames multiple times every millisecond to produce clear images from a non-UHD chipset.

Contrast and Lighting

When it comes to projectors vs televisions, one of the biggest issues is the loss of contrast and richness in black colors when lighting isn’t optimal. This projector is geared toward fast-action sequencing and uses an enhanced cinematic tone mapping profile to produce deep black colors.

The enhanced contrast is a desirable addition as the native contrast is only 30,000:1 which is somewhat lower than similar devices and significantly less than some of the industry leaders.

The BenQ TK850I brings a 3,000 lumen bulb to the party, ensuring you get bright, clear images even in partly lit rooms. The bulb has a lifespan of approximately 4,000 to 15,000 hours depending on the level of brightness used. Check the comparison versus UHD50X

Color Technology

The TK850I uses a four-segment RGBW color wheel to generate 1.07 billion colors using a 10-bit processor. This gives you an ideal range of viewable colors to ensure each image looks lifelike and enhances the clarity of text.

The projector is compatible with HDR Pro including HDR and HDR10 formats. You’ll need to have a computer player device that is HDR-ready and the content will also need to be in HDR. It has the capability to play 3D videos as well. It uses a DLP link for the glasses and can display the most common formats.


  • Ideal for watching live sports and playing video games
  • Provides a great option for medium-sized rooms


  • Some reports of software issues that can result in screen display issues

This projector has a few built-in features that are noteworthy. The first thing we will talk about is the built-in Android TV operating system. The OS gives you access to thousands of apps for streaming the best content. The OS also gives you access to Google Assistant voice assistant that makes controlling the projector easy.

What This Projector Does Well

This projector is designed with an eye toward filling the niche for viewers of live sports. It uses a combination of technologies to enhance sports television by improving color contrast and ensuring a smooth, lag-free image.

The combination of the HDR, contrast enhancing technology, and a rapid refresh rate makes the TK850I an ideal pic for live sports fans.

Just as it works well for live sports, it also is a great choice for playing video games. It can display images from all of the major consoles, including the latest offerings from Sony and Microsoft. It also can display content from a PC, so you can play your favorite video games on the big screen.

The projector includes a built-in 10 watt speaker which does a good job of providing plenty of sound. There are also provisions to connect the projector to your existing home theater system for even better audio performance.


The BenQ TK850I is an excellent option that provides the right level of enhancements to satisfy gamers and game-watchers alike. The projector offers the right amount of light to perform in medium rooms that are moderately well lit and it really comes to life when coupled with a high-quality screen and the ability to block out light.

Reports of issues have been uncommon. Some buyers have received units that display lines on one side of the screen or have issues with the projector switching video mode on half of the screen. This has most commonly been an issue that can be fixed with a firmware update, but occasionally has resulted in buyers using the three-year warranty (>>> Check on Bhphotovideo).
