Question about CTX Optoma EzPro 680 Multimedia Projector

1 Answer

The image projected from my CTX EzPro 680 Projector flickers on screen

We recently bought a new laptop (Dell, XP) but now our old projector does not project a stable image on the screen. The image flickers and is often split (the top part of the laptop screen is on the bottom of the projected screen) I have been able to correct some of the split screen using the tracking and frequency controls on the projector's menu, however it has not corrected the flickering. I have changed the screen resolution but it does not help.

From my experiences working with projectors, more than likely you will need to replace the lamp

CTX Optoma EzPro 580

Hi, Optoma USA recommend that you set the PC resolution to SVGA (800 x 600) or XGA (1024 x 768). Your HP Pavilion ze 4900 default resolution is S = SXGA (1400 × 1050) or X = XGA (1024 × 768). I would assume that your cable(s) are properly mated/attached from the laptop to the projector. If on pressing TV Now! One-Touch button with a TV icon at the top of your keyboard to switch the display to the TV-Out mode, there is no picture projected, you can try to manually lower the screen resolution of your PC. Try lowering it to the 800 X 600 setting in your Display Properties. Also, you may want to check if the Dual Display Mode is enabled/activated. You can try different resolution setting as long as the projector can handle it. Hopes this works and give you an idea. Should you need more assistance, pls post/comment. Good luck and kind regards.
