How do you fix your HP laptop monitor that flickers?

Answer 1

AnswerI dropped my HP laptop and broke the factory screen. I plugged the computer in to an external monitor and it checked good functionally. I ordered and replaced the LCD screen only to be annoyed by an intermittent flicker of the new screen. It took a while to figure it out but I solved the problem.

I have the HP G71-340US Notebook (17" screen). Once dissassembled the screen has a rail assembly on both the right and left side that it mounts to. There are 4 screw holes on each rail but the computer only comes with 2 screws on each rail mounting to the screen. My mistake was that I installed the top 2 screws in the top holes and the bottom 2 screws in the holes DIRECTLY ABOVE the bottom holes. There is a wiring strip that runs along the bottom of the screen and if it touches the housing it will cause interference/flicker. All I did was remove the two bottom screws and install them in the very BOTTOM holes to lift the screen off of the screen housing. No more flicker! Makes me wonder if maybe some of the laptops off of the shelves might need to be checked. A lot of issues about HP and flickering screens on Google. Hope this helps.

Answer 2

You probably have it set for non-interlaced picture. A non-interlaced picture scans every line on the monitor in sequence and this can cause flickering. Setting it to interlaced will cause the raster to scan every other line and then go back and scan the lines it skipped on the first pass. Televisions do this routinely to prevent flickering but its user-selected on computers.

Answer 3

your LCD is broke if its flickering. you need to get a replacement

It could be broken, but not necessarily. What is your refresh rate set to? If higher than the monitor will support, it can flicker.

Answer 4

Disable it? You can't enable or disable it.

Screens usually flicker because the refresh rate is too high and the monitor can't perform at the resolution and refresh rate you want. This can cause flicker.

How do you disable it? You don't. Lower the refresh rate or your resolution. You can also buy a monitor that supports higher resolutions and refresh rates.
