Which is why you actually have to address your notebook manufacturer each time you have a problem with your graphics card. As you can actually see the system information on startup, on BOTH screens, obviously there isn't anything wrong with the monitors nor the graphics card, but instead there is something wrong with the settings. I've experienced this before and got it to work. You have an ATI card and Catalyst Control Center. I imagine that you, in CCC/Display Manager, can see your secondary display icon, which you have then cloned. I understood this correctly, right? Okay. When I had this problem, it was due to a refresh rate/resolution incompatibility issue with my two monitors. Now, my secondary monitor was an HDTV (Philips), but the logic seems to be the same. Step 1) In Display Options I have a drop-down from which I selected something like (display only refresh rates/resolutions which works on all displays). Mine is in Swedish so I'm just guessing what it's called in English. #Viewsonic monitor driver vista windows#.#Viewsonic monitor driver vista license#.#Viewsonic monitor driver vista software#.#Viewsonic monitor driver vista drivers#.#Viewsonic monitor driver vista mac os x#.
