HP Laptop HDMI no longer works
The HP laptop starts normally under Vista. The Windows symbol comes up on the HDMI connected LCD-TV, then disappears and the words "Incompatible video signal has been received. Check output device settings."
First try changing the screen resolution in your laptop and check if you are able to get the display in the external LCD-TV.
- If the problem still exists then check the screen resolution in LCD-TV.
Refer your LCD-TV manual book to know the supported resolution.
- Update your graphics card driver.
