The BenQ TH685P ($799) illustrates why specifications don’t provide all the information you need regarding a projector. It is an improved replacement for the BenQ TH685 and shares very similar technical specifications with its forerunner. The only real difference is that they don’t have two VGA connectors like a PC input and a passthrough monitor out.
While both projectors accept 4K HDR input and downconvert it to their native 1080p with HDR, our tests showed that the TH685P’s HDR input resulted in a noticeably better image, which is a significant benefit for a gaming and home entertainment projector in this price range.

BenQ TH685P review: Design

The Benq TH685P is 12.28 x 8.56 x 4.33 inches, which is pretty big. However, it is surprisingly light and has several ways to mount it. You can use the holes in the bottom to hang it upside down from the ceiling, or you can put it behind a screen and project the picture from the back. You can also put it on a table and use the three adjustable feet to change the angle and level of the picture. You can buy this projector from its official website.
BenQ TH685P review: Performance
The Benq TH685P is an excellent monitor for gaming. It has a great response time and bright colors, but it’s not quite as bright as some other monitors in its price range. When playing games, the Benq TH685P has great input lag. This means that whether you’re playing with friends or by yourself, you’ll always be able to keep up with them. If you want something that’s easy on the eyes and doesn’t need much (if any) tweaking right out of the box.
BenQ TH685P review: Setup and Connectivity

The BenQ TH685P is designed to be portable and has a simple setup process. Manually zooming in or out by 1.3 times and using automatic keystone correction in the vertical plane make it simple to center the image on the screen. The TH685P’s rear is quite standard. Two HDMI inputs let you connect various devices, while a network port and a 3.mm headphone jack let you play music from elsewhere. The majority of users will likely use the 3.5 mm jack for audio. The TH685P features a functioning 5-watt speaker, but it has low loudness and poor quality.

The BenQ TH685P projector came out in 2021 and can be purchased right now. The price of the projector depends on where you buy it, but it usually costs about $749.99 USD.
It’s important to remember that prices can be different in different countries or regions and during sales or promotions. For the most up-to-date information on prices and availability, you should always check with official retailers or BenQ’s website.
