Last week I bought a USB 3.0 4KDP to DisplayPort adapter and new external monitor. Setup was super easy and everything was working well.
Last night I received a notice that some important updates to Windows were ready. After installing those updates and rebooting my laptop, my external monitor shows up with “No DisplayPort Signal” and in Windows Ctrl Panel -> Display, the external monitor is gone and it only detects the laptop screen.
The adapter’s blue light turns on when booting up, but then quickly turns back off.
I tried uninstalling and reinstalling the DisplayLink software 7.8 and tried 7.9 as well.
Any help would be appreciated.
