[ベスト] input not supported on monitor aoc 240348

I hook up the computer via hdmi from the video card to the monitor and I get a black screen and a floating box that says "Input not Supported" I know that both the monitor and cable are working, cause I tested them with my laptop But the pc can't seem to display on the monitor And all the fixes I see use windows to change resolution settings

Input not supported on monitor aoc- Requirements A second monitor If you are using a HDMI to VGA adapter and it is showing "Input not supported" then First go to your second monitor (you need two monitors for this), and go to display in setting see your first monitor's desktop resolution andThis is what it's set to on mine and I know fine that my monitor doesn't support 75hz, but I can see the screen You might want to try changing that value to 60 Hz, keep all the quotations and everything the same
