Ok, so to start with I've had an R9 390 for a few years and have recently added a HD 6450 from a spare computer to the mix (not running in crossfire, if they even can). I have a dual monitor setup and would use both the DP and HDMI output on my R9 390 but I've noticed a drop in frames and want to get my second monitor running off the HD 6450 but when I plug the HDMI cable into the HD 6450 then to the monitor it doesn't give any video output. In device manager my computer registers the HD 6450 but it makes no attempt to output to the monitor, device manager only recognises my first monitor. If anyone has any idea, please respond, if you need any more information just ask. I've tried installing drivers for the HD 6450 from AMDs website but to no avail. The HD 6450 was working yesterday in the spare computer.
