PC monitors of all kinds.
Hello guys,

I have a cheap Samsung B2230 LCD that has only one VGA port.

The problem is that it seems to always automatically choose wrong Coarse and Fine values and I have to correct them manually using Clock and Phase test image from

This seems to happen when I use fullscreen applications. Almost every time when I play a game and return to desktop afterwards I have to correct Co/arse and Fine (the screen is fuzzy).

Also computer restart seems to do it to.

I have tried different cables but nothing really changed.

Is there anything that can be done? Is the display broken, or am I doing something wrong.

Thanks for help.
