I contacted the manufacturer before buying the HD 6770 and was told that as long as I had a Displayport monitor or adapter I could run four monitors. My intention was to use this as an upgrade from the HD 6450 FLEX. This card would not run the three monitors that I currently had going with the 6450. I ultimately returned it and re-installed the HD 6450 FLEX
Negative Review
