My Ati Radeon HD 5450 PCIexpress card with DisplayPort will not let me use 3 monitors, why? I have a new computer running Win7 and the Ati Radeon HD 5450 PCIexpress card with DisplayPort. It shows all three monitors but, when trying to enable the third, I am told that I have to disable one of the others first. All ports work but only Two at a time. Why?!! I am using CCC 10.7 along with the most recent driver.
Also, it says it uses EyeFinity and I cannot find that anywhere. Is it integrated in the driver?
