    I am thinking of purchasing the Z10 Pro after using the Z8 Pro for some years.

    I moved away from using the Z8 Pro as I always had an issue setting a decent picture quality on my Samsung TV's.

    I could never get it set quite right for my eyes.

    Is the Z10 Pro image output improved over the Z8?

    Thanks for any info.

    Note: I did try the Z8 calibration thread...it helped a bit but still not an image to my requirements.

    Z8 Calibration

    Hi folks,

    I'm new around here and I hope this helps a few people and welcome any suggestions or other tips.

    I do not personally watch 4k material through the Z8. My sources are both European and North American IPTV never exceeding 1920x1080i/60fps.

    I change the Z8 between 1080p/50Hz and 1080p/60Hz and I prefer to let my TV convert to 4k at the display itself as it displays the best PQ for SD/HD IPTV material.

    The output of the Z8 was metered with a calibrated i1 Display Pro whilst running slides…

    The picture quality the Z10 ProMax is excellent and if you have a 4K TV… a poem… 👏🏽👏🏽👏🏽👏🏽

    4k movie is flawless on my z8 as well, it all depends how you setup your gear, z10 pro has not better picture quality. Just read the specs mrneilypops and posts made til this day on the forum about the box. Less settings as well if I interpret all the complaints about the box. For sure its the newest box, but better picture quality nah, hdmi 2.1 wont make any difference if the rest of your equipment is not setup to handle it.

    Blue_eyes Yes. As you see from my original post I own a Z8 Pro and have tried the calibration thread.

    I no longer use the Z8's and have reverted to nvidia shield pro (x2)

    So, no tuning options in the Z10 might be a bad thing...but it could be a good thing...

    I felt I was fighting the Z8 Imprex engine v Samsung picture settings...

    The Z10 is in my Amazon basket...just considering pushing the 'Go' button lol...

    Just buy the Z10 Pro Max and try and decide for yourself. Unless you need a third mortgage on your house to afford one.

    Otherwise disable all picture enhancement settings on your Samsung and (only) use the Imprex engine of the Z8 to adjust the image to your preference.

    The Samsung settings can be conflicting the Imprex settings.

    Blue_eyes Caveat emptor...that is Latin...check it out dude.

    1. I can afford to buy as many of these boxes as I could possibly want.

    2. There is a reason for a forum...to check products in advance and product advice after purchase.

    3. Why should I have to disable any Samsung settings that work perfectly fine with nvidia shields, other boxes, etc... 'Conflicting'???

    4. I have all enhancement settings disabled on all my Samsung TV's.

    Cheers.

    You speaking about picture quality but never told what exactly doesn`t match. What is so bad for you and ok for many others?

    That you want me to “check it out” and addressing me as “dude” is telling a lot about your arrogance and disdain. By assuming others weren’t taught Latin you merely highlight your vanity.

    Suum cuique.

    Picture quality is a personal and subjective matter therefore it is hard to compare subjective opinions, especially on a forum.

    System settings on your TV might try to overrule identical or similar system settings on your Z8 and vice versa. Hence the suggestion to disable all picture enhancement settings on your Samsung and (only) use the Imprex engine of the Z8 to adjust the image to your preference. This minimizes the chance that either one causes a conflict of which one has control over the setting.

    I am the wisest man alive, for I know one thing and that is, and that I know nothing

    Good luck hunting.

    I have an old SONY BRAVIA television and the Z10 PRO, increases my picture quality, by a big margin, compared to my old cable provders quality, and I am an old man with poor eyesight! :smiling_face: :smiling_face:

    I have a Z10pro, and I can receive HEVC channels from my provider, however when I switch I notice a discolarazation and a bad picture Quality for the first 10-20 seconds, is this inherent to HEVC, my old TV, or is it a provider service issue?

    Anyone noticing similar effects when using HEVC channels?

    It is HLS feature, if the stream can not be send in full bitrate or not streamed at beginning with full rate and need some time to get full and constant bitrate. It starts with lower and goes to highest bitrate, in this time is the resolution much lower.

    On Z8 you can turn on or off this feature, on z10 it works automatically in background.

    HLS fast start explain.

    HLS fast start ON: Start playing the lowest bitrate first (default)

    HLS fast start OFF: Start playing the highest bitrate first.

    Thanks Sam fore the explanation I also have the occasional loss of sound,when I switch to HEVC channel, is this also the same mechanism?

    If it happens in same time (low rate) could be reason for that.

    Hello Sam, I just found out, that my service provider also has a (HEVC/4K) channel list, and the problem of bad picture quality is totally absent when I use this list of channels and ZAP without any delay or loss of picture quality !

    Then use this m3u playlist protocol instead other from Portal if it works better for you. My subs. don`t have problems with low bitrate, no matter if sd or 4k, full bitrate from beginning, so it is provider/protocol issue in your case.

    Sam ,unfortunately I dont have a m3u playlist, as my provider for some reason only provides Portal connection !

    Thanks,for the referal to the article about converting your portalURL in M3U format. I tried it out several times, but each time a code 7 came up. So I contacted my provider and it appears the server I am on, can either give me m3u line with user and pass,or portal line.

    The server I was on before can be used with portal and m3u at the same time (not at the same time on 2 devices), so this lead to some confusion on my part! But anyway, thanks for the support. :smiling_face:

    Bit the bullet and got a z10 pro max delivered from Amazon today to see if it's a upgrade from my z8 pro,if it's not I can return it, the z8 always felt slow in syncler /kodi so only used it for iptv and would switch over to my nv/shield for apps which can be a pain,the z10 is alot more snappy than the z8,not as fast as my shield or odroid n2 but faster than the z8 for sure,syncler actually feels good to use,truehr/dts hd is passing through kodi to marantz sr7012 without issues,this and ui speed improvement was what I was after,like how I can lock the cpu to maximum performance in settings,couldn't do that with the z8 where it's cpu would hover between 400-1200 mhz,no doubt that's why it feels slow in apps although mytvonline app is always good,picture quality seems OK,don't notice any real improvement over my z8 but I'm gonna compare them tomorrow,but all in all I like this box,not havin any real issues jst yet so I think il be keeping it

    Check on your z10 following settings and change if needed:

    1. Settings ->Display-> Screen resolution-> Display Mode

    2. Settings ->Display-> Screen resolution-> colour space settings (depends from TV what is exactly supported)

    2. Settings ->Display-> Image settings

    3. Settings ->Display-> HDR output mode -> adaptive or off
