There are times when we try to use our desktop computer only to find that there is no image appearing on the screen. This can be a disconcerting problem especially when we are in the middle of finishing an important document, homework, business report, and so on.
Stay calm. Perhaps the monitor is not broken and the issue can be easily addressed. Check the cables to see if they are connected properly. Unplug the HDMI cable and the power cable. Then plug the power back in. The monitor should perform a diagnostic on itself by showing bars of color. If you see this, then your monitor is fine. Plug it back to the PC.
If the issue persists, then the video card might be the culprit. Consult a computer repair Brooklyn shop for further help. They are likely to update the drivers and test the card on another system to isolate the cause.
