Wondering if anyone can can answer this for me....
I have a Samsung 55" HU6900 4K UHD TV. This TV's HDMI inputs are HDMI 2.0, but I was told that this TV only had one HDMI input that supports HDCP 2.2. (HDMI 3 MHL) so had to use that input to watch Sky Q (non subscriber at present). So depending on the situation, I would take out the cable to use the ATV and then my Xbox One S if I wanted to watch a 4K disc and then back again. Quite the ballache.
Last night I decided that for the time being I was going to keep the Xbox in HDMI 3 and put the ATV into one of the other HDMI inputs (1) until I get a TV where they are all HDCP 2.2. compliant.
So I was shocked and surprised that when I loaded the ATV up and chose the source (HDMI 1), the output was showing as 3840 × 2160 50p....
Picked a couple of films I know to be 4K (Wonder Woman and The Last Knight), did the pulldown on the ATV and they showed as 4K as well.
So I have 3 questions:
1) Has my TV always been able to take 4K video (and therefore me being a complete idiot not realising this) from the other inputs, just that Sky needed to use HDMI 3?
2) Is it a case of the ATV merely upscaling the content (I have everything within Match Content turned on)? I'm pretty sure that I've put the Xbox One S into HDMI input 2 and only got a 1080p image from it.
3) Or could it be the cables I was using before compared to the ones I'm using now (OMARS Premium HDMI Cable) mean that I'm now able to receive a 4K image on these inputs?
I mean I've switched the ATV between HDMI 1 and 3 and the screensavers look exactly the same..
I'd be interested to see what people think.
