I have an AMD Radeon R7 M260 GPU in a Fujitsu Lifebook A555 laptop running a win10 64-bit. The GPU is running pretty good for its value however I am experiencing some troubles when connecting to a second screen (usual monitor). Here is the catch, I only get these black flicks during gaming experience when I connect through HDMI. VGA to VGA works perfectly. Why do I know that the problem remains on the GPU or maybe latest AMD drivers and not in the HDMI port? That is because when I connect the laptop through the HDMI port, everything works perfectly when Intel HD Graphics 5500 is operating (surfing, video, audio). However, whenever I try to launch a game, the AMD GPU automatically activates and then I start getting the black flicks for every 4-5 secs on the monitor.
Is there a solutions to this? I would be grateful if someone could help since I currently own a Lenovo ThinkVision x24 monitor which has only HDMI port and displayport available.
