    Ultimo4K Display Issues

    Recently purchased Ultimo 4K, running OpenViX 5.1.030 (2018-06-25), also tried 5.1.031 but same problem, display output is set to 2160p - 50hz, as you can see from the screen photo I am getting a strange pixelation. This develops after approx 45 mins of viewing the same source, if I select Menu and then exit back to the programme pixelation goes but comes back in 5 mins or so, if I change channel pixelation problem goes away but comes back in 5 or so mins. I have reflashed the box & same issue occurs. Tried different HDMI leads and problem is the same. My TV is a Samsung UE40MU6400 and any changes in the TV display settings make no difference to the problem, neither does moving the HDMI lead into different inputs.

    Anyone have any ideas.........................Spevs............... .IMG_20180718_201934977.jpg

    I really don't think it is the HDMI cable, I am wondering if I have a hardware issue on the new box.

    Channel pixelation problems, to me anyhow points to a signal issue, I would look at the cabling from either A/ If cable/virgin etc or B/ if Satellite etc

    If I use my old Solo2 instead of the new Ultimo with all the same cabling inputs etc I get no issues, when I 1st had the Ultimo this problem did not seem to be there and started after about a week. Why do you think it takes about 45 min to 1 hour to show itself and if I selct Menu or switch channels it goes temporarily.

    Well one is a 1080P receiver and one is a 4K receiver...... I agree with Andy but if you are running in 4K mode then you cannot rule out the TV

    Have you tried 1080P??? Do you get the same issue?
    I would also turn off ALL the Samsung tweaks like motion control etc and see what happens.

    I will try the Ultimo in 1080p, but I don't see that it is a signal issue, because if I use BBC Iplayer in 4K I dont get the problem, nor do I get the problem if I play 4K material from a pen drive on the TV, also if play a HD recording of say the World Cup Final on the BBC the lines of pixels appears after about 45 mins, however, if I fast forward the recording to say 30 mins into the game the pixelation appars again after 45 mins but the game is at 75 mins and not 45 mins which suggests to me it is not the signal but a problem with the graphics output in 4K mode on the Ultimo.

    So that to me points to your dish/cabling/f-connectors etc. I would disable one tuner and test, then enable and disable the other tuner etc and test and see what results you get.

    If it happens on a recording, at different times depending on when you start playback, then surely the dish/cabling etc has nothing to do with the problem.

    That's exactly why I believe the issue is with the Ultimo Video Out

    You are comparing Apples, Pears and Oranges.
    Just because they say 4K doesn’t mean they are sending the same 4K content to the TV.
    You cannot say its down to the Vu+ just because thats when the issue started because before then you were driving the TV in 1080p.
    Don‘t jumpt to conclusions and try some of the suggestions 1st.

    Also check you are not trying to push a format your tv does not deal with (8bit, 10bit, 12bit, hdmi-colordepth) and Colourspace (YCbCr444, 420, 222, RGB).

    You will need to check the specs of your tv to findout what panel it has, if you are pushing 12bit colourdepth to an 8bit panel for example then you are sure to have issues.

    Absolutely correct, unfortunately the marketing departments of outfits like Samsung are not very good at explaining any limitations, they just want the „customers“ money.
