Gp2x Screen Issue

[vampire8bit]

When using my gp2x F100 MK1 unit, I see wavy lines running diagonally across the screen. It doesn't affect the gameplay when using emulators but is very noticeable on option and menu screens. What can be the problem? Is this normal on F100 mark 1 units? I'm using firmware 2.1.2.

Wavy lines? Do you mean interlacing?

They are not scanlines that's for sure as I get those and like them, but these are like ripples of water, is it interlacing? I do not know as I am not very technical about screens.

My 'First Edition' unit has this problem. You need to go to settings>LCD and move the slider until it stops.
