last week my computers power supply screwed up from a power surge and now I got it fixed and my tv says that the resolution is PC Connection "Mode Not Supported", nothing software has changed just replaced the power suppy and the resolution didn't change so I have no idea what is wrong the computer works fine on normal computers but my tv just will not detect it. I have absolutely no clue how what to do I don't want to buy a new thing I want my old setup back I just do not understand why it's not working. I tried changing it into safe mode but it still doesn't open up I can't even see the bios screen when I turn it on. the tv is a samsung and I am connecting it via an changing the computers resolution did nothing also.HDMI cable. Any idea on what to do?
