I'm trying to add a second monitor to my setup its an old one but i would like to add it anyway. I have my main monitor connected via DVI and the 2nd one connected via HDMI. When i had both monitors connected the 2nd was getting no signal and after a couple of minutes messing with display settings i noticed that im not allowed to set a resolution for my second monitor even though it is being detected by my pc. If you know how to fix this your help would be appreciated
