Why does my pc not connect to any monitor at home but works elsewhere

My pc suddenly stopped connecting to anything at home. I've tried different monitors and my tv. I replaced the HDMI and made sure everything was inserted correctly in my pc. I tried everything I could think of and still nothing. So I took it to a pc repair shop and it immediately started working perfectly. But when I took it back home I still couldn't get it to connect to any monitor I have. I'm not sure how to proceed at all

Hi @Itchuckles,

What is the make and model number of the PC or motherboard if a custom build?

Also the make and model number of the GPU card if it has one and you're not using integrated onboard graphics if it has this option?

Hi Thomas,

Some clarifications. You said you replaced the HDMI, I'm assuming you meant the cable, correct?

Also, at the repair shop, did they use the same ports on the graphics card? If they used another port, like a DVI port, or a DisplayPort that might still be working. It could just be the HDMI port has failed. I know this scenario sounds unlikely but was that verified? The fact that none of your possible display devices at home works, while the PC repair shop got it to work, makes me think bad HDMI port on the GPU card, or a bad cable that wasn't used for the test at the shop.

Alternatively there could have been a driver update for your card that glitched your HDMI port. Have you tried connecting to your home displays with other formats like DVI or DisplayPort?

Although getting no signal to your new monitor can be cause for concern, it’s arguably the easiest problem to fix. It simply means that the display has power, but it isn’t receiving visual data. There are several reasons why this happens and plenty of fixes you can try to sort out.

Force Windows to detect your monitor: Maybe Windows didn’t recognize your second display’s connection. To force it to check again, right-click the desktop and select Display Settings from the resulting pop-up menu. In the following window, click the Detect button located under the display diagram. In Windows 11, you can find this under the Multiple Displays section.

Turn the screen off and on: Some connection types don’t like hot swapping while a different monitor is powered on. Turn the display off and then on again. That may be all it needs to recognize the video feed and start displaying it correctly.

Verify cable connections: A loose cable can cause “no signal” errors more often than any other problem. If they do seem well secured, unplug, and plug them in again just to be sure.

Remove other peripheral devices: Disconnect any connected cameras or other unnecessary peripherals. If your display starts working afterward, these connections were probably interfering with your setup. You may need to find newer, compatible accessories or use connections on your PC instead of your monitor.

Hope this helps
