Since the Windows 10 1809 update, my second screen connected with HDMI on my laptop doesn't work anymore.
It happened at the time of the update (just before the screen worked, just after it stopped working).
I installed the latest drivers up to date.
Windows settings no longer display the second screen.
The screen itself and the cable still work well (tested with another computer).
The screen only displays "no input signal".
Laptop model : ASUS UX501JW
Graphics cards :
-Intel Iris Pro Graphics 5200
-Nvidia GeForce GTX 960M
The Windows diagnostic tool says "The current graphics driver has known issues" but the same version was working on update 1803.
The drivers (last updates) :
- Intel : installer 126.96.36.19958, driver 188.8.131.5258,
- Nvidia : installer 417.35, driver 184.108.40.2065.
See attached SSU.txt and DxDiag.txt
Any Ideas ?
(sorry if my English is not perfect, it's not my native language)
The second screen started working again during a reboot (although I had already restarted several times and the drivers did not change).
