My GPU is AMD R7 250x. The monitor is BenQ RL2455
When I connect the monitor using the hdmi, it just says "no cable connected". When I use the DVI it works fine.
I read somewhere that I may need to put in the gpu's properties the hdmi as an input, but I can't find anything about the hdmi in the gpu's properties.
What can I do? I need to connect more monitors and this way I can only connect one.
