Hey guys!. I got a used R7 250. And it was working ( I checked it directly ). Anyway, now after installing drivers on my PC, when I restart, my monitor says "Input timing not supported please change input timing to 1920x1080 60Hz". I tried going to the low resolution mode. But the error happens there too. So, is it a problem with the driver?. If anyone has a working driver for it, then please help.
