Jump to solution

Hello everybody,

I've bought  this new XPS 15 and updated all bios and drivers

when it resume from sleep the secondary monitor, connected via HDMI, has very high brightness

Tried to disconnect the cable, shut down the monitor and reconnect it but it remain the same

I've to restart the system to get the normal brightness and contrast

what should I try?

I have the same issue on mij XPS 15. All updates are installed. I only have the issue on the main HDMI port. Connecting a display throught my DELL DA200 does not result in a high brightness.

Has anyone found a solution rather that not using the hdmi port?

I have the same problem and rebooting all the time ***...

@Dell: any suggestions?

The ticket conclusion was it's for sure an interworking issue with my (non-Dell) monitor...

But since the last intel driver updates (think is was in June) the issue is gone
