Same issue as most i have seen on these blogs. I have a Dell 1520, hooked up to a Viewsonic VX2235. This is Setup information file for monitorsĬlassGuid= inf file to get this thing working for every time? I copied the MonInfo-report and my driver below. I just read this, but I don't know what to do, because the DTD is not in my driver. I just bought a 22" Acer Widescreen Monitor and it is sometimes working with my PC.
