Sky Sports UHD cuts out intermittently

[Dianson]

Watching sky sports on UHD channel.  Screen will go blank for a second and then come back showing the HLG HDR icon on Top Right of Screen.  No discernible pattern to the timing of the interruption so very annoying.  It's like the picture just drops out.  All well if just watching in HD so happy all cable connections are fine.  Any ideas?

What HDMI cable are you using?  (And how long)

Should be ok, but may be the issue.  Try another lead if you can?

UHD is significantly more bandwidth compared with HD.

Started getting this issue today, randomly. 

In fact, when I turned on the TV to watch Sky Sports UHD, my settings had somehow reset and I was prompted to enable 2160p viewing again in the menu. Never had this issue before.

Now getting the random intermittent cutout
