Making sure you’re running the latest graphics drivers for your system can sometimes fix problems with no signal errors. Update your drivers: Windows supports multiple monitors by default, but your current setup may not be configured correctly. Switching to another may be all you need to do to correct the problem. Sometimes ports themselves can go bad or somehow get damaged. You can also try using a new cable in case the old one has issues (bent pins, a short, exposed wire, etc.).Ĭhange the graphics port: If you’re using a dedicated graphics card with multiple output ports, try switching to another port. Try to remove the adapter if possible, or replace it with another adapter to see if this fixes the issue.Ĭhange data cable: If you’re using an older cable standard like VGA or DVI-D, you might want to try a newer alternative like HDMI or DisplayPort. If you are using an adapter to switch from one type of input to another, this may be causing issues with the other monitor. Use the buttons on your monitor to cycle through the channels and select the correct input from your PC. Verify the correct input: Monitors with multiple input options need you to manually select which cable and port you’re using, like HDMI 1, HDMI 2, DisplayPort 1.4, USB-C, and so on. You may need to find newer, compatible accessories or use connections on your PC instead of your monitor. If your display starts working afterward, these connections were probably interfering with your setup. Remove other peripheral devices: Disconnect any connected cameras or other unnecessary peripherals. If they do seem well secured, unplug them and plug them in again just to be sure. Verify cable connections: A loose cable can cause “no signal” errors more often than any other problem. That may be all it needs to recognize the video feed and start displaying it correctly.

As an ex-Windows Insider who beta tested Win10 from the start, I’m disappointed that this issue wasn’t caught before AU was released.Īlthough the picture for the lock screen was changed in settings, a second reboot shows that it reverted back to the same stock picture that was there before. It seems many people have had this issue after the AU. I rebooted and, sure enough, I was able to change the lock screen picture. Went to HKLMSoftwarePoliciesMicrosoftWindowsPersonalization then on the right side I deleted the Value: NoLockScreen I can’t believe I didn’t do this first! I Googled “Some settings are managed by your organization – lock screen’ and In fact after setting a lockscreen picture, one can turn lockscreen on (post 10) and keep the lockscreen image from changing.) After the AU I had to allow the lockscreen so I could change it to a picture. I had nolockscreen set before the AU and I could change the picture although the picture didn’t show. These interrelationships appeared in the AU. ![]() I don’t recall what they were during my testing. ![]() ![]() (Note lock screen and spotlight have some interrelationships. Perhaps a reinstall from the Media Creation Tool is in order. There must have been something changed before the upgrade. In this VM, I can change the lock screen picture in settings like your image in post #9. It is a VM that I keep as close to “vanilla” as possible just to be able to check out things that I mess up elsewhere ^).
