Grid lines accross the flat screen?

[NightTran]

I just notice now that my flat screen have alot of grid lines accross, not uniform but very notice when I play video, is it time for new screen or something about codec that I can fix?

Thanks

are the lines visible across the whole screen or just over the window playing the video?

I can't see it when the lines are under white or black screen but I can see when it is in diff color, not just play video, I mean I can see it if I change my back ground to diff color then black or white I will see it clearly

Thanks

Could also be your video card. I would try another monitor and see if you can narrow it down.

If it isn't an LCD is your Flat Screen perhaps a Sony Trinitron tube? Trinitrons have a couple of thin wires that run from side to side to hold the shadow mask in place.

I will try another screen and check, no it is not sony It is a Dell


PS I just fix it myself : after turn off my screen off when ever I am not using it and just let the computer run the lines when away, look like the board hot and show on the screen
