If you are switching between the VGA head and the DVI head, with a DVI to VGA adapter on a Radeon card please check this...
16 Bit and 32 Bit color modes on the DVI to VGA adapter are reversed.
TEST:
Set WinXP to use the classic desktop, with 32 bit color and switch between heads.
EXPECTED RESULT:
In 32 bit color mode, title bars have a smooth color change from dark blue to light blue, in 16 bit mode banding is seen.
ACTUAL RESULT:
32 bit on the VGA head ... all is fine.
32 Bit on the DVI to VGA adapter shows banding indicating it is 16 bit.
16 bit on VGA head... banding as expected
16 bit on the DVI to VGA head... no banding, 32 bit color is seen.
CONCLUSION:
Color modes are reversed on the DVI to VGA head only.
Could someone confirm this happens with their card, or not.
Thanks.
