Hopefully someone can shed some light on this matter.
I read the AMD released a new version of the catalyst drivers, but I found I can't use those but whatever Dell releases. So I downloaded and installed the drivers for the 6970 for my M17x R3. By default, it seems these new drivers come with the EDID option disabled. After installing, I enabled the option as it had been working normally with the prior version.
The problem is that now all whites turn to yellow if I enable the option.
I tried re-installing the drivers (after complete removal).
I tried switching from DisplayPort to DVI.
I tried using the 'Restore Defaults' option in both the monitor (U2311H) and the catalyst drivers.
I am guessing this is either a registry error or driver/reporting issue.
Thanks in advance for any help!
