I bought a MSI Radeon HD 7770 PCI-E display card and it doesn't work well with my monitor (Samsung S23A700D) at 120 Hz. The problem is that there is flickering no matter what software I use. The flickering caused bigger problem when it crashed a few applications.
Both old and new drivers have the same problem. What's strange is that the problem was not there until a few Windows updates were installed. The CPU is AMD 6 core CPU and the system is Windows 7 64 bit.
If I change the refresh rate to 60 or 100 Hz, all the problems are gone but I spent so much money for a 120 Hz monitor, how come I can't use that feature?
I tried Asus GPU Tweak to raise the 2D GPU core rate to 400 MHz and also increased the memory speed but that doesn't help.
What else can I do to resolve this?
Thanks!
