I have a ATI Radeon X1300Pro 256MB and it has minimum Pixel-Clock 7.12MHz.
I noticed when I run certain games the screen goes out of sync.
I am using the following SwitchRes parameter:
pal
crt_range0 15625.00-15625.00, 50.00-50.00, 1.500, 4.700, 5.800, 0.064, 0.160, 1.056, 0, 0, 192, 288, 448, 576
What can one do to make sure the pixel-clock doesn't go below 7.12MHz?
I can get around this problem using Xorg custom modelines by using horizontal resolution doubling, but I'm unsure how to put that to practice using SwitchRes.
