Vertical bands, static, or noise appear in the image. What should I do?
-
If the projected image seems to contain electronic interference (noise) or static, try the following solutions:
- Check the cables connecting your computer or video source to the projector. They should be:
- Separated from the power cord to prevent interference
- Securely connected at both ends
- Not connected to an extension cable
- Make sure you selected the correct Signal Format or EDID settings in the projector's Signal I/O menu, if available for your image source.
- Adjust the Noise Reduction, MPEG Noise Reduction, and Deinterlacing settings in the projector's Image menu.
- Adjust the Blanking setting in the Installation menu to hide noise or static on the edges of the projected image.
- Adjust the HDMI IN EQ Level setting in the projector's Signal I/O menu. Change the setting to Low if you are using a short HDMI cable, or change the setting to High if you are using a longer HDMI cable.
- Select a computer video resolution and refresh rate that are compatible with the projector.
- If you adjusted the image shape using the projector controls, try decreasing the Sharpness setting to improve image quality.
- If you connected an extension power cable, try projecting without it to see if it caused interference in the signal.
- If you connected an A/V system that does not support eARC/ARC to the HDMI2 (eARC/ARC) port, the image may be distorted.
