Chosen Solution
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
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
