Okay so I was playing csgo and I changed my graphics aspect ratio to 4:3 to get blackbars to support native resoltuion 1024x768 and it worked fine however I did a restart and now my monitor will not turn on at all I cant see it whatsoever. But at first it got to the windows logo and then went black but now upon starting my pc it doesnt do anything my monitor wont power on to detect the signal. However if I turn the screen on manually it says no signal and turns back off again. Any solutions? Please help im sorry if this is typed like a mong im on my phone because I cant use my pc
