Review: Impressive projector and a reasonable price - Great picture , reasonably priced , I had the w703d before this and it was a brilliant priced superb projector , and this is an improvement on that one and that's not easy imo , not sure what noise others hear , I sit under mine and not a sound is heard , the only thing I found a bit awkward was accessing the menu options
Review: Stunning Gaming Projector - After speaking to a Projector retailer, i decided to go for this gaming projector as i wanted to get the full potential out of my PS5, I wasn't disappointed, the image is absolutely stunning. There are a few minor details that i didn't like but can live with. PRO's - Image quality amazing for both gaming and movies 3 gaming settings, RPG, FPS,SPS Fan noise Low Built in APPs for streaming Movies Easy to set up once in the correct position Option to pay over 6/12 months Can project upto a 300" screen CONS - NO X,Y keystone for changing screen size, which means you need to get the projector in the exact position to match you screen which can be tricky. I had to buy a ceiling mount as the throw projects at an upward angle and not straight Speaker volume not great but i have a small room so is enough for me, a larger room would need a soundbar. Turning off the projector takes about 2 mins to power off. The Price is high but you won't get a 4K 90" Tv for less than £1100 Would i recommend this projector? YES, Although it has some cons, they don't outweigh the pro's. Before you buy i recommend that you study the projector scale so that it can be positioned in the right place as i said you can't change the screen size through the settings, screen size is determined from the distance you have projector from the screen

## Questions & Answers

**Q: Can I use a wi-fi dongle so that in can connect speakers wirelessly.  is there any way to use Bluetooth speakers with this model?**
A: Simple answer is yes.  I use a Wi-Fi dongle connected to my blue tooth speakers and there is no lag.  Hope that helps.

**Q: Could i upgrade from benq 1080p projector th671st to 4k tk700sti directly without changing ceiling mount?**
A: Hi there, thank you for your question on our TK700STi gaming projector. Please be informed the position of the ceiling mount would have to be changed if you would like to upgrade from TH671ST to TK700STi. For further detail, you can use our “BenQ Projection Calculator” to calculate the accurate throw distance for your preferred projection size.

If you have further questions regarding the TK700STi gaming projector, please feel free to contact us using the Online Chat service on our official website, and our customer care specialist will be more than happy to assist you. Thank you!

Warm Regards,
BenQ Customer Care

**Q: What size could this project from roughly 2.4m?**
A: I checked and from 2.5 meters away from a 44cm table, I can get a 101inch screen

**Q: I have a 120 inch screen and the distance to the screen is 3.3m will this projector fill the screen**
A: YES, with a "But". The distance from the screen for 120" needs to be between 1.833M and 2.205M (The zoom range).  Optimum distance is 2.019M.
If you download the manual, there's a handy diagram on Page 13 that helps you calculate the projection distance from the screen.
If you are working with a fixed distance of 3.3M and can't get closer to the screen you will then have a problem as the image will be too large.

### ⭐⭐⭐⭐ wont load iplayer
*by P***E on 13 November 2025*

good picture and reasonably bright but unfortunately has two annoying issues: 1) keep telling us to optimise for gaming mode and that holiding ok for 2s will stop it asking but then the same issue comes back every time you turn it on. 2) the chromecast that is built in won't allow bbc iplayer to be installed.
