This function is only working with Windows PC/Laptop which is designed with and has PgUP and PgDn keys. HDMI (designed with MHL function) and USB Mini-B connection are required from the projector to your Windows PC/Laptop.

The maximum distance supported by the wired remote control is 10 meters.

Regarding the CEC (Consumer Electronics Control) functionality on BenQ projectors. We understand your expectation for full bi-directional CEC support. However, after careful consideration of usage scenarios, we have designed our projector to limit CEC control to one-way communication.

This approach helps avoid unintended behaviors such as powering on all connected source devices simultaneously when the projector sends a CEC power-on command. In certain setups, this could cause user inconvenience or confusion. Additionally, it is important to note that not all source devices respond consistently to CEC commands—some may ignore power-on signals altogether.

We truly appreciate your understanding, and we will continue to work on the possible implementation of bi-directional CEC features in future updates and models. Should you have any further questions or suggestions, please feel free to reach out.

High-brightness projectors are engineered to deliver exceptional luminance, making them ideal for environments with strong ambient light, such as large conference rooms, auditoriums, or outdoor settings. 

Achieving this high brightness often involves technical trade-offs that can influence color reproduction.For users who are more sensitive to color accuracy, we recommend choosing the medium Lumens projectors with pure RGB color source and high color space such as our W4000i, W2720i and W5850, or you may provide us with the usage scenario and we’ll recommend the most suitable model for you.

We continuously strive to improve our products by integrating advanced technologies that enhance both brightness and color accuracy. Thank you for your understanding and continued trust in our products.

Please check the following settings to correct this issue.

1. If the source gives the correct 3D information to the projector, the projector will switch to 3D automatically.
  If your source is from PC or steaming content, please select the correct 3D format via OSD Display > 3D > 3D mode.
2. Check the user manual and make sure that the resolution of your content supports 3D.
3. Press the DLP Link button on your 3D glasses to resync the projector and 3D glasses.
4. Please try to change the HDMI EDID setting to Standard.
5. Make sure that no other Projectors are sending DLP Link signals in the same room.
6. Watching in a relatively dark environment to avoid being influenced by other light sources.
7. Check the battery level on your DLP 3D Glasses
8. Adjust the watching distance and screen size within a normal range(Specs)
9. Stay in a fixed position, and try not to move too far/quickly on your head/3D glasses.
10. Try to adjust a colorful setting on the projector and avoid external light direct to your 3D glasses/screen.
11. If it's still not working, the issue might be caused by Hardware margin. You can switch to another projector or 3D glasses for a try.
