The BenQ HT3550 has a brightness of 2,000 lumens. That’s ideal for spaces with low ambient light and you won’t need to turn out all the lights to use it. It will struggle in brighter rooms, though, especially ones with lots of windows. The 3,200 lumens put out by the BenQ TK810 make it the better choice for these spaces. While it’s still not equipped for daytime outdoor use, you won’t need to worry about the light level in most indoor environments.

Picture Quality

Both of these projectors produce a true 4K resolution paired with a high image contrast. The biggest difference between them here is their color performance. The BenQ TK810 covers most of the Rec.709 spectrum but the CinematicColor on the BenQ HT3550 expands this to the DCI-P3 space that’s the standard for movie theaters. It’s also factory calibrated and uses HDR color mapping for a more realistic overall image.

Wireless and Streaming

There is no built-in wireless on the BenQ HT3550. The BenQ TK810, conversely, has both Wi-Fi and Bluetooth, along with an Aptoid interface for streaming shows and movies directly to the projector.

Gaming Performance

Neither of these is what we’d call a gaming projector. Both have an input lag over the 30ms threshold for serious gamers, and have a resonable but not great 60Hz frame refresh rate. With that said, the BenQ HT3550 has a lag as low as 34ms, making it responsive enough for most casual gamers.

The BenQ TK810 lets you watch movies and shows on the big screen wherever you are. Its lamp is powerful enough to maintain the image contrast and color even in rooms with lots of ambient light, and the built-in light sensor lets it automatically optimize the brightness to your space. It’s also portable, with a compact design and a weight less than 10 pounds, and has a fast and easy tabletop setup.

It’s easy to get your content to the BenQ TK810, too. Along with dual HDMI inputs, it supports wireless casting through Chromecast and has an integrated Aptoid interface so you can watch content through streaming apps without an external device. Controlling it is just as easy, whether you use the included remote or download the BenQ Smart Control app on your phone. Both options support Google Assistant Voice Search, though bear in mind this won’t work for all streaming services.

Whatever you like to watch, it’ll look it’s best on the BenQ TK810. It has a true 4K resolution with HDR color mapping and support for HLG. This ensures accurate colors, and with coverage for 92% of the Rec.709 color gamut, it can produce the nuanced shades and tones that bring a picture to life.


  • True 4K picture with good contrast and color
  • Full wireless connectivity with wireless casting
  • Bright enough for lights-on viewing
  • Easy to use with multiple control options
  • Built-in streaming interface
  • Compact and portable design

BenQ HT3550

BenQ HT3550

You’ll feel like you’re in a movie theater when you’re watching the BenQ HT3550. Its 10-element all-glass lens produces a sharp image, with XPR processing for a true 4K resolution. Along with this, it has CinematicColor technology, exceeding the Rec.709 spectrum to cover 95% of the wider DCI-P3 color gamut. This color is calibrated to ISF standards at the factory, and is further enhanced by the HT3350’s sophisticated HDR-Pro tone mapping and HDR10 contrast.

The BenQ HT3550 is also easy to install. Its throw distance is shorter than many standard-throw projectors, and it has a good array of adjustment options for fine-tuning the alignment, including a 10% vertical lens shift and automatic vertical keystone correction. There are also 6 aspect ratio options and multiple Movie Modes and Sound Modes so users can tailor the image to perfectly match their content. See how it compares to the newer BenQ HT3560.

The BenQ HT3550 is similar in size and weight to the TK810, making it similarly portable. However, it doesn’t have any streaming or wireless support, so you’ll need to connect external content sources through the dual HDMI inputs. It’s also not as bright and may be prone to washout in spaces with high ambient light.


  • Sharp, high-contrast 4K picture
  • Exceptional color performance
  • Flexible and fast installation
  • Lightweight and portable
  • Low enough lag for casual gaming
  • Full HD 3D


  • Low lamp brightness
  • No streaming or wireless connectivity
