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.

Split screen functionality works with InstaShow Button and AirPlay.

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

An optional wireless dongle (EZC-5201BS) will be needed for wireless projection.

Yes, this feature is supported to project images onto an uneven surface with warping patterns from 5x3, 10x5, 15x9, and 24x15 to fulfill your demand.
You can enable warping by going to: Installation > Geometry > Warping

Please note that:

• Auto Screen Fit, Focus, Corner Fit, and Keystone will be not available for adjustment once warping is enabled
• Warping will be not available for adjustment once Screen Fill is set to 16:10, 4:3, or 1:1

For more instructions in detail, please check “Warping Pattern” in the user manual.

Yes, this feature is supported, but please note that devices connected via the USB-C port require a USB-C cable and must support DisplayPort Alt Mode (version 1.1 or above) to project videos.
In terms of the specifications for the USB-C cable, please choose a cable with USB-IF certification.

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.

Regarding the light leakage phenomenon, it is a physical characteristic of DLP (Digital Light Processing) projection technology, mainly related to the optical engine structure. Since DLP projectors use a digital micromirror device (DMD) to reflect light, you may notice slightly scattered light in certain scenes, especially in dark rooms, or lens shift to a special location. While this phenomenon does not typically affect the main image quality.

Light leakage can vary depending on factors such as ambient lighting conditions, projector placement, and viewing distance. In some cases, a small amount of light may spill onto the ceiling or walls, particularly in a dark environment, solutions include adjusting reflective furniture or using light-absorbing velvet borders outside the projection screen frame to reduce the light diffusion and light leakage caused by ambient reflected light.

The projector is designed for optimal performance in bright rooms. If you primarily plan to use the projector in a dark environment, we would recommend the W Series home theater, as it offers a more suitable option for enhanced viewing comfort and experience.

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.

The projector is using the pattern below to do focus adjustment.

To have a better focus adjustment, please make sure:

• The pattern below is visible, unobscured, or unbroken throughout the focus process
• The wall or physical screen you use is flat without curves or bumps

The projector is using the pattern below to do Auto Screen Fit.

Auto Screen Fit would not work if the pattern is invisible, obscured, broken, or not in the range of your physical screen throughout the process.
