Why is my frequency not supported?

I have a problem with my pc and I have a normal hdmi monitor and one with a dvi connection… If I connect the with dvi there's no signal and then I thought with an HDMI adapter it cleared up but no the frequencies are not supported again, on my Xbox one s also not unless I set the resolution to 720p… Then I changed the resolution on the pc and still comes the error message… Can someone help me there… Ps the origin of the question comes because my girlfriend plays on the xbox and I want to play on the pc

Then change the frequency, 50. 60 or whatever the monitor can do.

Thanks try it… Ps I made a mistake was definitely helpful

There are DVI-A, DVI-D and DVI-I, the plugs are identical, but the HDMI adapter does not play if it is only programmed for one of these systems, so it is especially important for such things, the eBay - Read the item description carefully.

Hey when i put the dvi cable in the plug to the pc clamp no signal
