Hi,
is there a reason why I cannot chose "YCbCr 4:2:0 10 Bit" while displaying at 2160/24p?
When I tried to pick it, the HiMedia box tells me, that this is only allowed while in 2160 50p or 60p?
Thank You.

Buggy Firmware. Will need to wait for fixes. I had same issues

in my case i have probleme with HDR10.
- I have new Demos 4K HDR from LG, now I can used both (LG and Sony) for testing the HDR10.
- Sony Camp 4K HDR
- LG 4K HDR Daylight
- LG 4K HDR Tech
- LG 4K HDR Rays of Light
----------------------------
HDR10 with YCbCr 4.2.0 10Bit : the colors seems to be like 8bit gradient/gradient dithering, the High Dynamic range works well.
HDR10 with YCbCr 4.2.0 8Bit : the colors seems to be like 8bit gradient/gradient dithering, the High Dynamic range works well.
HDR10 with YCbCr 4.2.2 : the colors seems to be like 8bit gradient/gradient dithering, the High Dynamic range works well.
AUTO with YCbCr 4.2.0 10Bit : the colors seems to be like 8bit gradient/gradient dithering, the High Dynamic range works well.
AUTO with YCbCr 4.2.0 8Bit : the colors seems to be like 8bit gradient/gradient dithering, the High Dynamic range works well.
SDR with YCbCr 4.2.0 10Bit : No problem, the color gradation is smooth
SDR with YCbCr 4.2.0 8Bit : No problem, the color gradation is smooth

in addition there is something very strange,I have half of the screen that has the problem, look on photos below you will see the right side with the problem et the left side seems to be normal
HDR10 / 4.2.2
The colors seems to be like 8bit gradient/gradient dithering is more discreet than 4.2.0 10Bit and the gradient/gradient dithering is on the full screen.

HDR10 / 4.2.0 8 and 10Bit
The colors seems to be like 8bit gradient/gradient dithering, and the gradient/gradient dithering is about half of the screen on the right side only.

I would like to repeat my question in more detail:
Will the firmware be fixed for this issue?
I need 4:2:0 10 Bit otherwise I cannot get a picture at all with 4:4:4 10 Bit.

Buy a cable capable of 18gbps!
What TV you got?
-
If it would be that simple, I would have already gone the cable route.
I am asking about a feature in the HiMedia that is not working at the moment and would like to know when this will be fixed and not for a new cable solution.
I own a JVC X7000 projector.
-
I have the same projector and can tell you that HDR does not work with anything below 4:4:4.

Hi magnifico,
1. The HDMI cable comes in the box, what quality is it? Doesn't it support 18 GBPS? should we buy a new cable?
2. I watch just a few 4K demos very rarely, I mostly watch 720p and 1080p movies. For 720p and 1080p, which selection should I prefer for better video quality, 1080@60HZ 444 10 bit or 2160@60 HZ 420 10 bit?
Thanks in advance.

I believe you. But I do not like to chroma upsample, I would like to prefer the ability to display at 4:2:0 from a bitrate perspective as well from a "do not alter the signal" perspective. UHD movies are mastered at 4:2:0 and I do really not see why I should upsample it.
One reason for buying the Q10 was to be able set those settings individually and therefore I ask Futeko when they will deliver what they offer, or seem to offer, in their settings.

3. Choose HDMI auto adaptation
But this solution does'nt work with my beamer. Because then happen this here...

Goog god... That is totally fine because that is technically not possible!!!
There is no 3D in the 4k world!!!!!
Go to 1080p and play the video!

I totally agree with you. And yet both Uhd players currently on the market do chroma upscale the discs and whenever I tried to play something with the Q10pro with less than 4:4:4 it looked washed out and clearly worse.
But it works... AND THE JVC showed in the Info: 10bit HDR and deep color was greyed out.

What I understand is, that we need 10 bit signal for the HDR Realisation.
In my TV environment: "Panasonic DXW904 with UHD Premium certificate and HDR (HDMI cable is certified for 4K (18,2Gbit), HDR also)", I don`t see HDR as of today.
As writen from McFreibier: when do I get what I`ve paid for.
My conclusion with FW 1.06 repeated again:
Setting of YCbCr420 10Bit ist possible (under 2160p / 60Hz)
But....with this setting I get no video signal from the started Video, Audio is OK.
If I switch to 1080p and YCbCr420 10Bit it works. But this is not the capability I bought the Himedia for.
Therefore I`ve the choice to see the video signal on my Panasonic4K under 8Bit (means no HDR), or swichting to 10Bit (means HDR) but have no video signal.
To check the problem from the TV side, I`ve switched the Input signal at TV in a compatible mode (means without HDR capability). I see the Himedia video signal at once.
I guess the 10Bit signal sent from Himedia is not correct.
It looks like, Himedia get`s the setting to 10Bit working, but nothing behind it?
I have still the same problem > see next paragraph: In memory...
Can anybody really confirm, that genuine 10Bit/HDR videos under 2160p/60hz will played and shown in HDR on his TV?
In memory my post concerning 10Bit/HDR Video signal with the first Firmware (Box delivery):
I`m wondering that I can`t set it to YCbCr420 10Bit but to 8 Bit.
If I try to change the settings to 10 Bit, the screen comes back in some seconds with the old setup, means 8 Bit.
My TV is the brandnew Panasonic DXW904 with UHD Premium certificate and HDR (HDMI cable is certified for 4K, HDR also). Therefore I should do it.
For my point of view I must set 10 Bit to see HDR.
Additional Infos:
Tested with the HDMI cable out of the box also, same result.
Checked the TV specs: (see enclosure) > should no problem at all.
At the box:
Changed the custom display format to 1080p (several Hz) > it works, 10 Bit possible
If I go back to 2160P > only 8 Bit possible

I am able to play my Blu-rays and 4K HDR demo videos using YCbCr420 10Bit thru Sony 4K TV. Proper video and sound.
TV HDR mode is "Auto" and Display is set to 2160P 60Hz.
FW is 1.0.7. Had not tried on previous versions.
As per the bandwidth calculator 3840x2160p @60Hz and 10 bits (custom) is 17.92 Gbps

Table:
4k60hz 4:4:4 10bit is >18gbps...so it is not in hdmi 2.0a specs

I am unable to get Dolby TrueHD or DTS HD Master Audio when the setting is kept to YCbCr 4:2:0 10 Bit and 4K@60.
Does anyone else face the same issue?
