No HDMI output on 4K TV with Lafité pro III ( Iris Xe graphics card and i7-1360P processor ):

[ced]

Hi all,
I can't get the laptop to output on the TV monitor through HDMI port.
I still can use this TV monitor with my old laptop at 4K 30Hz , that laptop has a GTX950M nvidia card, and that works perfectly.
When I first linked the new laptop with the TV monitor, it worked a few minutes but every 20 or 30 seconds, the screen went black for a second.
Now, I can't get anymore a single image back displayed on the TV monitor from this laptop.
When I plug the HDMI I cable, there's repeatedly this sequence of events:
During 1 or 2 seconds on the screen of the laptop screen, the displaying part of the screen is shrinked a little bit and comes back to the full screen area as it does before laptop screen is displayed on TV when it works, but actually it doesn't. On the TV, there's just "3840x2160 at 60 Hz" briefly displayed and then just "No HDMI Signal".
I've updated the Arc driver to its latest version.
Is there something I can do to fix that ?
Thanks for your help !

Can you post a screenshot your optional updates page as well please?

Have you set your display settings in windows? Is it registering the second screen? Are you duplicating or extending the desktop?

Can you post a screenshot of your optional updates?

Can you post a screenshot of your windows display settings which the TV connected?

Di you order with or without windows as you've cropped that off your specs list?

Hello,

The display pb was due to the cable. I've bought a new HDMI 2.0 cable today and it works perfectly. The other one is perhaps not 2.0 cable, I bought a few years ago. Strange that it can however display 4K 60 Hz intermittently. Anyway, with this new cheap HDMI 2.0 cable, it works just fine.
Thanks !
