A friend just re-installed my AMD Radeon 6450 because I was having issues with lack of certain functions (including screen saver).
HP TouchSmart 610-1280qd Desktop PC
Windows 7 Home Premium
The installation solved the problems, but created a new one. When I turn on the computer it acts as though it's starting but then I get a black screen for about 15-20 minutes. If I wait long enough, I can then log on.
After managing to log on, the pop up message said: "DisplayPort Link Failure" The system has detected a link failure and cannot set the requested resolution and refresh rate on your DisplayPort display. Your display might not support the requested resolution or there may be an issue with the cable connecting the display to your computer.
Friend suggests changing the resolution to see if that solves the problem, but the preview that I get shows a resolution I don't like.
I am clueless, so please be kind and simple in your responses.
Thanks for your help.
