A short while ago I go a new card, an ATI Radeon HP2600pro 512mb memory.Could get it to go properly, couldn't get right resolution, tried it in my son's new rig & came up "out of range". Striped mine apart put in different M/B & came up with same result. Sent it back & they tested it & said it's working ok & returned it to me at a cost of £10. I feel I'm being ripped off because they wont change it & I can't get it to work. Am I doing something wrong or what? never had any trouble before.
