My desk only have displayport so i have Hp DP to HDMI adapter. After 6 month, my monitor say no video signal. I've try to check everything. CPU Fan and Power could still run. I tried to press numlock and caplock and it's still work. Then i connect my monitor to other old PC by VGA and the monitor has signal. So, i buy another DP to Hdmi adapter Ugreen and Vention but it's not still work. My neighborhood don't have any computer shop and i don't know what error. Please resply me soon. Thank you.

@minhvn2k5 -- After 6 month, my monitor say no video signal
Does your monitor have more than one "video-input", e.g., VGA or DVI or HDMI or DisplayPort?
If it does, then you have to use the buttons on the monitor to select one of these possible inputs.
If you select an input that is NOT active, you will see that "no input" message.

Hello @minhvn2k5
"Then i connect my monitor to other old PC by VGA and the monitor has signal"
the computer, maybe the problem is not the monitor
Try if possible to test another monitor, on the computer, same thing, it is the computer not the screen, which is in question!
