3. Check the DisplayPort cable’s condition
There could be a problem with your USB C to DisplayPort cable if you get a no signal error on DisplayPort monitors.
As a result, inspect the cable’s general condition. If the cable isn’t in perfect working order, you may need to replace it.

- Reconnect your computer.
- Start your computer.

6. Check if your PC supports DisplayPort Alternate Mode
All USB C ports do not support DisplayPort Alternate Mode. DP Alt Mode is a USB C feature that lets users connect DisplayPort VDUs to their computers directly.
Check the documentation or website for your PC to see if the USB C slot supports DP Alt Mode. If your USB C slot does not support DisplayPort Alternate Mode, you’ll need a USB C to DisplayPort monitor converter to fix the problem.
Those are the most likely solutions for the USB C to DisplayPort no signal problem.
If none of the previous solutions works, the display could be having a hardware problem. If your VDU is still under warranty, you may be able to return it to the manufacturer for repairs.
