What card do you have and did you go to AMD's site to download new drivers?
Hello mister G. Thanks for your response.
My display adapter is ATI Radeon HD 2400 PRO.
Yes I went to AMD`s site to update the adapter. I tried several times, but each time they responded that I had the latest version.
Maybe the next step is to "enable the ATI adapter using the Displays Manager"as they suggested earlier. But I do not know how to do this!
