I have just installed a new Radeon VE over the weekend and now when I run the THX optimiser from Monsters Inc the first test which tests contrast levels shows all 4 white boxes at the same level - No matter what level I have my contrast on my AE100. I am using W98 + Power DVD4. Is it because I am using an unbranded board which has inferior DACs? Any help would be appreciated. Azzo.
