I have alot of Dell Optiplex 3010's with Window's 8 that we ordered HIS radeon HD 5450 silence graphics cards to have triple monitor displays. The card has a DVI/VGA and a Disply Port. The disply port we have a Bizlink ks10009 (B) adapter connected to a DVI going into the monitor. In order for me to get the computer to read the card we had to boot the computer in legacy mode. Once the card started displying we were able to get two monitors working. Here's the kicker.
The card will recognize all three monitors in the windows adjust resolution settings page. However it will not allow all three to display at the same time, only two at a time. we attempted to disable one of the monitors to see if we could get the third one to come up and sure enough it popped right up, so i know all of the ports on the card are working. It just seems that we are missing a setting in here to get the third display working at the same time. Can anyone help?
