    In regard to your query, your TV has an 8-bit panel. Hence, it can only accept a maximum 'Colour Depth' of 8-bit from HDMI external devices. Though, your TV can support RGB 4:4:4, YCbCr 4:4:4, YCbCr 4:2:2 and YCbCr 4:2:0 in an 8-bit 'Colour Depth' once 'HDMI UHD Color' is set to 'On'. Go to Settings > Picture > Expert Settings > HDMI UHD Color.

    A bit more testing to do now............Spevs

    Well, after hours of testing, due to the intermittent nature of the problem and so many things to change, I appear to be going round and round in circles, so I have given up on my Ultimo 4K. One last thing, if there are any other Ultimo 4K users looking at this, the temperature of the CPU on my 4K was generally in the 60+ degree area, I see from the WOS spec sheet for the 4k ambient temp range should be in the region of 15 - 35 degree's. I have two Solo2's which generally run around 40 degree's but as these are not an AMD chip, I would be interested to know what other Ultimo 4K users boxes are running at..................Spevs

    Well the next step is to try your Ultimo4K on another 4K tv (ideally a different model to your tv).

    Not easy I know, but atleast then you can confirm if your Ultimo4K is causing the issue or not.

    Another option is to try your box in 1080p mode and see if you get the same problem, although this won't fully rule out an issue with your tv or the ultimo4k.
