Long story short, my ~5 year old Samsung Q60 has developed the ubiquitous purple blotches and, with the 2021 Apple TV 4K 120 hz, on the way I figured it was time to upgrade the TV. Before someone asks, it's in a bright room and OLED's just don't have enough nits, hence the QLED. On Friday I upgraded to a Q95, with One Connect Box, might as well tidy up the cables at the same time. Quick review, the Q95T is awesome, the picture quality is amazing and the specular highlights are simply spectacular.
Pretty simple swap right, just unplug the Q60 and plug in the Q95, unfortunately not. Note no ARC, eARC or CEC before or after and used EXACTLY the same HDMI cables. The cable box (1080P) works OK, but had no joy with either the 2017 ATV 4K or the Sony 4K BD player. Spent most of Saturday trying all sorts of HDMI cable swaps, for example with the One Connect Box located in the rack I can use a short (750 mm) HDMI cable from the XMC-1 instead of the previous 5 m cable, FWIW all HDMI cables have the same 18 Gbps rating from the same manufacturer.
For a test, out of the XMC-1 HDMI outputs I plugged both the Q60 (worked just fine when powered up alone) and the Q95 (wouldn't work when powered up alone) then tried the ATV 4K and the 4K BD Players. I did try swapping the HDMI 1/2 outputs, made no difference. Didn't change any settings in either source and I did try every setting that I could find on the Q95T, none of which made any difference whatsoever. Pointing to a HDMI HDCP handshake problem.
I then tried connecting all 3 sources to the One Connect Box and using the ARC channel, no joy there, just more pain. As well as not connecting it also introduced a whole pile of CEC issues, not unexpected.
Downgrading the ATV 4K output to 1080P didn't help either, as well as trying 4K 50hz and 4K 60hz and chroma 4.2.0/4.2.2/4.4.4, plus HDR on and off.
FWIW at all times, while trying the above, the 1080P cable box worked just fine (except CEC of course). Plus the 4K sources worked perfectly when plugged directly into the One Connect Box.
I have ordered some new HDMI ultra high speed 48Gbps HDMI cables and a toslink cable as a fall back (desperate huh).
All suggestions gratefully accepted (and yes I am considering the XMC-2 upgrade).
Cheers
