You're probably better off disabling the other display adapter, preferably in the BIOS.
Jim, thanks for your reply.
Forgive my ignorance, but which other display adapter? Only the ATI one is displayed in the device manager.
My computer is running Windows 7 64 bit SP1, and every other application (including video editing software) works perfectly. Surely this implies that the problem is with Premiere Pro? I previously ran PP CS4 with no problems whatsoever.
Is your computer a laptop, or a desktop that has a display adapter "chip" on the motherboard?
Also, do not count on Windows Update being correct about your driver being up to date... you need to go to the ATI/AMD site for your model card
Sorry. Most folks having this problem are on a Laptop with a built-in graphics chip. I assumed that was the case here.
it's a desktop. I've been to the AMD site and downloaded the latest driver. Actually the latest beta version caused a blue screen so I don't know what went wrong there. Anyway, the latest driver is installed.
This must be a PPCC problem and I hope they're fixing it. Or am I wrong?
I wouldn't count on Adobe fixing this. It's more likely a system issue somewhere. Even if it is a problem with PP, you're likely to wait months for a fix, so...
