I have Acer Monitor VG240Y.

I upgrade my desktop pc with new motherboard ASUS PRIME H510M-A and Intel Core i5 11400f processor.

Now when my pc boot, on POST SCREEN I get message input not supported? I am not seeing asus logo when system boot and I can not enter BIOS? When system load windows I am having the image on the screen and everything is OK.

How to fix this? It is very frustrating.

    Do you have the monitor plugged into a mainboard video output port or a GPU card video output port?

    Hi Jack, thank you for your quick response.

    I tried to put HDMI cable in motherboard HDMI jack - no image at all...

    I tried with VGA cable on my motherboard - same thing - no image at all, black screen.

    I tried with my Graphic Card removed from the motherboard - and tried with HDMI and VGA port on my motherboard,

    no image at all, black screen.

    The only time that I get POST image screen is when I used HDMI port on my Graphic card Saphire Radeon RX570 conected o my large LG TV 55" 4K... That time I get the POST screen and ASUS logo on start, and I can manage to go into my BIOS.

    I use my HDMI GPU port .

    When I remove my graphic card, I even remove CMOS battery for more than 30 seconds - to "reset" the BIOS to factory settings.

    No result at all, same thing - "Unsupported input" and black screen during the boot POST screen.
