I recently upgraded from a GTX-750ti to a Sapphire RX 470 (4gb) and the day i got it, my gpu has been acting weird... while im playing games or just strolling on the browser... there is the sound of hdmi connecting and disconnecting a new display comes in although i have only connected one hdmi cable from the gpu to the monitor... ive tried everything from deleting nvida,intel and amd drivers with DDU and everything else unfortunatly none of them worked so if anyone of u guys know any fix please do let me know...
