The subject is this: I recently bought a video card (used) ATI/AMD HD 7970, this videocard has no VGA connector and I am currently using a CRT monitor 17 '', to connect this monitor I had to use a DVI-to-VGA adapter, but doing this I see interference (as if they were scanlines but minimal), it's quite annoying and I wonder if there is any way to eliminate this interference.
Before I had an ATI HD 5670 and I never had this problem (that videocard came with VGA connector)
Thank you very much!
