Nope, only DP and HDMI here (and some old C64 monitors

) ...
But I resolved it, there are two Radeon now in the screen settings, so it's Radeon9600P and Radeon9600P.1 and if I choose the second one everything is ok again ... thanks for putting me on the right track

Sadly the next issue appears, the VRam is nearly maxed out, even if just using some explorer windows and everything is slowing down, oh well ...
