Exactly the second one. Small horizontal streaks. This
problem increase with higher clock rates. On 70Hz there
are only two small areas but on more than 90Hz the right
side of the screen wobbles. The top-left corner is always
perfect.

Hmm, yesterday I have tested the box with another monitor
and there are the same problems so the card or the driver
arouse my suspicion. Shouldt I buy another card or is it
possible to change this in the code?
Many thanks
