Thank you very much for providing those files.
I can see here that the driver currently installed is version 4574, on the following link you will find different drivers, please try to install them in order to try to fix the problem:
First try Beta 4590:
If the problem remains try driver 4552:
Not sure if you tried the following driver already, it is version 4483 provided by Dell, you can try it if the problem persists:
Did you test it with a different HDMI cable?
If you connect the laptop to a PC monitor does it work fine?
This is just to rule out a possible problem with the HDMI port itself or the cable.
Any further questions, please let me know.
Thank you very much for your answer!
Installation of your first two links exited with error that the drivers are not valid for my computer. I don't know why. I see that Dell drivers versions start at 20.19, 21.20, but all yours at 15 - is it ok?
So, I again as a first time after Windows installation tried latest 184.108.40.20683 from Dell site with no luck and then the oldest 220.127.116.1144 - and it work! After that, just for expiriment I downloaded pre-latest from Dell site 18.104.22.16854 and it also work! So I stopped on it
As I understand, the problem is between 4454 and 4483. I opened for experiments, so if you get me another proper links - I'll try it.
Thank you again for your help!
