[SOLVED] My GPU isn't recognizing my second monitor anymore.

Usually, I use two monitors - both are 1080P 60HZ, one is connected via HDMI, and the second one via DVI. Yesterday I powered up my computer, and I noticed that just one screen is working. On AMD's control panel it does say that only one monitor (the DVI one) is connected. However, the screen says "no signal" (and if I disconnect it from the GPU it says "Cable is not connected"). I thought that the problem was in the HDMI monitor, but then I connected him to another source and it worked flawlessly. Then I thought that the HDMI port on my GPU is dead, but I tried to connect the DVI monitor via HDMI and it worked (!). I also tried to reinstall AMD driver several times and I also replaced my PSU with no success. Do someone here has an idea what could be the problem?

When you replaced the PSU, did you get a higher Watt PSU or an equivalent model?

Both PSU are generic. the older was 500W and the newer is 550W. I have i5 2320, HD 7790, so I think that even 500W is more than enough.

Yea it should be okay but I had a 650W PSU and on paper it should have been sufficient for my build but when i introduced a second monitor, it damaged my PSU over the course of couple weeks. I dont think it is your PSU, Im going to look into it and try to get back to you.

Solved it.
I plugged the "broken" monitor to another computer and it worked. Then I plugged it into my computer and it worked!
