Hi, interestingly, I have now received a reply to my question from B&O support.  They say ‘it is not possible with Beovision Eclipse since the HDMI 2.0 input does not support UHD 10 bit at full colour sub-sampling 4:4:4 above 30 FPS, in other words, the TV does not support 4K 60Hz 10 bit input’

But colour sub-sampling of 4:2:2 and 4:2:0 must be supported. Most, if not all,  4K HDR streams are encoded using HEVC 10 bits,  4:2:0 sub-sampling. Youtube HDR material is encoded at 4:2:0 using the VP9 codec . So colour sub-sampling of 4:4:4 is definitively not needed for now. So set the box to 4:2:0 and you will be fine.

Sounds good, but how do I set the box to 4:2:0?  I can’t see how to do it

Oh sorry, I thought mentioning the Eclipse and sky q box would have made it clear

Any idea how I can set the box to 30hz?  I cannot see how to change the setting.  If possible, this seems like a good solution

Hi Thorne,

Are you in the UK? I'm basing my answers on UK Sky Q boxes, but I know sky Q is available in some other countries and I don't know what differences (if any) there are.

Whilst B&O's response about 4:4:4 10bit @ 60Hz not being supported is correct - Sky Q boxes, at least those in the UK, output in 8 or 10 bit 4:2:0 which is supported.

Please advise whether you are using the sky supplied HDMI cable, or an alternative cable, and if the latter, how long it is and whether it is premium certified. Also, as already suggested, please try connecting direct to the panel to see if this works, as it really isn't possible to advise further until this information has been gathered.

Kind regards,

Martin.

Hi Martin. Yes, I am in the U.K.  Your response has provided me with the likely reason for my issue. I cannot connect the box direct to the panel because the TV is wall mounted and all the cabling is hidden in the wall.   Because of the fact the TV is wall mounted, the HDMI cable is much longer than 2 meters, so I reckon that could be the reason. It is not the sky supplied one because that was way too short, but it is premium certified

Guess I’ll gave to content myself with 8 bit

Thanks for your helpful answer

If the cable used is premium certified, there really shouldn't be an issue - I often use 5m premium certified cables for wall mount installations - much longer than this and you usually have to resort to fibre optics.

Of course a faulty or damaged cable cannot be ruled out, and that's going to be a pain if it is chased into a wall.

If the TV is on the hinged wall bracket, you should find there is enough cable length to try it temporarily in one of the sockets on the screen, but this probably will feeding it back out from the soundcentre and any sock it is enclosed in.

Kind regards,

Martin,

So are you saying you have successfully wall mounted Eclipses connected to sky boxes with UHD 10 bit, using very long cables?
