Hi,

There are a couple of places where UHD Deep colour needs to be turned on to use 10 bit. Firstly enable it for HDMI 2 on the screen (the port that the sound centre uses to connect to the screen):

Home -> Settings -> Picture & Programmes -> Picture (I think it is in the 'Picture' menu, but I'm doing this from memory, so if not check under 'General')

Then enable it for the HDMI port that your sky box is connected to on the sound centre (HDMI A/B/C or D) under:

Home -> Settings -> Sound & Beolink -> Sources 

Hope this helps,

Martin.

Hi.  Thanks for replying. Yes, I have both Ultra Deep Colour settings turned on, but still won’t connect at 10 bit

Any more thoughts?

I've generally found the sky q boxes don't reliably detect 10 bit if you use the auto detect, but I've never had an issue getting them to use 10 bit when selecting this option manually providing both the UHD deep colour settings are turned on. You usually get a blank screen for a number of seconds, then just about enough time to select the button confirming it is working before the timer runs down to zero and it reverts back to the previous settings.

As Mikipedia mentioned, it may be a cable issue so would definitely be worth trying it connected to one of the HDMI ports on the screen (remembering to enable UHD deep colour on that port too). You obviously won't have PUC control then but it may help to narrow down the cause.

That could well be the reason, but I won’t be connecting sky q box to the screen because I want to use PUC.  Can you explain why it makes a difference if you conn3ct it to the screen rather than the speaker

The suggestion is to connect it directly to the screen for testing, not permanently, as it may aid in determining where the fault lies.

If it works when connected directly to the screen, but not to the sound centre (assuming you use the same cable), then it is likely the issue is with the sound centre, or the short HDMI cable connecting the sound centre to the screen.

If it still doesn't work when connected directly to the screen, then the issue is likely to be with the sky box or the cable you are using (or I guess, potentially with the main board of the screen, but that is unlikely).

Are you using the HDMI cable supplied with the sky q box? If not, how long is the cable, and is it premium certified? Not all cables will work with the higher bandwidth requirements of 10 bit UHD.
