Windows 10: Display not working

Hi there,

I have a Lenovo Yoga720 & a ViewSonic VX3258-PC-mhd display, using a Samsung USB-C to HDMI adapter.

This exact setup was working on my TV Linden 40" LED/LCD, model 'L40MTV17a' perfectly.


I am getting "no signal" no matter what I do. This is not an issue with the monitor or cable as I can use Samsung Dex with the same set up literally unplug from computer, plug into phone - bingo. Additionally, I have borrowed my partner's monitor same model which has had the same issue. So it is something to do with the Computer display set up.


I have:

1. updated all the Windows updates

2. updated Bios

3. updated then uninstall/reinstall display drivers through device manager & Lenovo's site

4. updated Windows pnp driver

5. run "sfc /scannow" which did not return any integrity violations

6. the USB-C connections the right way around charger is the rear port, output is front. But also swapped them just to check.

7. Turned off & disconnected the whole lot for 10 min then reconnected


*not necessarily all in that order but I checked the connection after each troubleshoot


I'm not sure if an issue but there is a "Citrix Indirect Display Adapter" however this has been updated etc.


I am really at a loss, there must be some dumb random thing I am missing.

The tutorials provided are just a list of troubleshooting steps. Use only the steps which apply to you.

Since none of the troubleshooting steps here worked, I'd suggest you do a Clean install.
