Iris Xe connecting to Samsung LCD LED TV over HDMI -> no HDR

[Mage0]

Hello,     

I have a 2017 Samsung LCD TV here (UN50MU6300).  It has a menu option for enabling HDR ("UHD color") on specific HDMI ports.  When using this HDR option, I get a strange result connecting my Dell 7306 2n1 to the television.  The TV doesn't detect any signal.  Meanwhile, the laptop's internal monitor goes blank (like I want it to when connecting to an external display), but the laptop seems to flash a brief image of the desktop every 2-3 seconds like it's trying to reconnect or right itself somehow.

Everything works fine at 60Hz sending a 2160p signal to the TV if I stick with SDR in the TV's settings.  Any ideas?

I have tried several combinations of Dell/Intel driver packages for the video chip as well as firmware updates, etc.  No dice so far.                  Thanks - BGU

• Does this happen with HDR only? Is it right after you enable the HDR option?
• Does this happen if you enable HDR from Windows?
• Did it work properly before?
• Can you list some of the drivers tested?
