Vero 4K+ EDID issues with Samsung 8 Series smart TV UE55MU8009

Help and Support
1

Hi @ All,

I received my Vero 4K+ today and I have trouble with UHD (HDR) Files with more than 30 FPS.

As example the file “Samsung and RedBull See the Unexpected HDR UHD 4K Demo.ts” is a UHD HDR sample from Samsung with 59.949 FPS, you could easily find it in web. But it is only played back with 30 FPS HDR.

I figured out that the Vero has incorrect EDID from my TV (Samsung UE55MU8009 is directly connected, no AVR in between):

osmc@Vero4K:~$ cat /sys/devices/virtual/amhdmitx/amhdmitx0/disp_cap
480p60hz
576p50hz
720p60hz
1080i60hz

1080p24hz
2160p30hz
2160p25hz
2160p24hz
smpte24hz
smpte25hz
smpte30hz

But I’m pretty sure that this TV supports 2160p60 on all four HDMI inputs. I checked that (same port same HDMI cable) against my Desktop PC (Win10, GTX970) and 2160p60 works well and is also directly suggested by the Nvidia graphics driver.

I still also have an RaspberryPi 3 connected to the TV running OSMC (it should be replaced by the Vero), following output:

For me it looks like both systems has a problem with the EDID data, maybe something OSMC specific? Any patch possible?
Are there any possibilities to tell the Vero manually which resolutions are supported by my TV ignoring any EDID data?

This is an major issue for me.

Edit: When I reboot the Vero4K+ it comes back with 720p60 which results in a ugly overscanned picture…

Hi,

We can definitely override EDID data. This is quite easy to do.
But first thing to check: can you give us the output of cat /sys/devices/virtual/amhdmitx/amhdmitx0/rawedid

It’d be handy to know what EDID your TV is giving us; to see if it’s a parsing issue or a problem with what your TV is giving us.

Cheers

Sam

And I found out something interesting. There is one “Video Data Block” within “Block 1” which contains the formats recognized by the Vero4K+ missing the 2160p/4K formats with higher frame rates. But there are a second “YCbCr 4:2:0 Video Data Block” within “Block 1” which only contains the missing UHD and 4K high frame rate resolutions.

My guess is that the Vero4K+ parses only the “Video Data Block” and doesn’t recognize the information in the additional “YCbCr 4:2:0 Video Data Block”.

Maybe it’s quiet unusual that Samsung split these information in two separate blocks to distinguish between the color formats but it looks like a bug in the EDID parser.

Thanks. This is useful

5

Hey,

It’s good that my report is useful, but what happens next? Any bugfix in near future? How could I fake the EDID in the meantime?

I don’t want to sent the Vero back but this is not what I expected and without a solution I see no other way.

You can put your own disp_cap in /home/osmc/.kodi/userdata with the resolutions you’d like supported. This will override EDID. You will need to restart Kodi after.

7

Hi,

I copied the disp_cap from /sys/devices/virtual/amhdmitx/amhdmitx0/disp_cap and added lines with the correct resolutions I think (see below). But the only effect I can recognize is that the first line has something to to with the resolution which is set after a complete reboot.
But the kodi resolution is still 3840x2160p30 after reboot and 30hz is the highest framerate available in the menu. But now there a two times 3840x2160p available (maybe because I split the possible 2160p resolutions) and there are an additional 4096x2160 resolution with low frame rates which I haven’t expected at all.

Playback of a 59.9/60hz video file is still 30hz.

Is some kind of documentation available for the disp_cap file which string means which resolution in particular. Google found nothing on the first two pages. I see no logical optino to distinguish between fractional and non fractional refresh rates and between 4096x2160 and 3840x2160 which is both supported by my TV.

And there are other very annoing things with Vero and resolutions. When I set the Vero to 1920x1080p60 I get it but by default my TV does overscanning. Than I have an option to adapt the resolution to the screen. With Auto and Off I have overscan, it fits only with the On setting.
But when I connect my old Notebook (only HDMI 1.4) and select 1080p60 I haven’t any overscan and the option adapt to screen is grayed out on my TV. So there must be a difference between the Vero FullHD and the one from my Notebook.

With your notebook connected your TV probably switches to PC mode which normally automatically deactivates overscan (and also other image enhancement options for less input lag) on most TVs. That’s probably the difference…

9

Hey,

I checked that against my RaspberryPi and it behaves exactly the same at 1080p60. So I think that’s ok.
But I still haven’t 2160p60. I’m going to play a little bit with the disp_cap file but I don’t have much hope.

Have someone 2160p60 working in the Kodi menus and library with the Vero4K+?

Best,
Bimbo385

10

Yes — but we really don’t recommend doing this.

The scaler on your TV will be better. Instead you should set it to 1080p and enable adjust refresh rate for 4K auto switching

11

Yes Okay,

but the option should be available and it should be working. But in my case 4k60p playback and menu isn’t working at all.

Edit:

I’ve selected 1080p60 as menu resolution and the result is that UHD content with 60hz is played as 1080p60 instead of 2160p60 or at least 2160p30.

I’m still looking for a reference for the disp_cap, my is now:

Next Edit: I got it:

The trick is to add “420” behind the 2160p50/60hz resolutions in the disp_cap. I would guess this is for the YCbCr 4:2:0 color space. But how to know this… I found it out by chance while searching for the weird smpteXYhz resolutions. Here some peoples have posted their disp_cap with the 420 at the end and I just tried.

I still don’t know what the “*” is good for, maybe a mark for native or recommended resolution, but I haven’t recognized any effect.

Is there any action on the OSMC side to fix the obvious bug in the EDID parser?

I will keep my Vero4K+, because it works for me but I wasn’t happy with the support.

My custom disp_cap is now:

osmc@Vero4K:~$ cat /home/osmc/.kodi/userdata/disp_cap

Hello,

The asterisk (*) marks a preferred mode. Some TVs do not advertise one.

I’m very sorry to hear this and I hope we can meet your expectations. It sounds like you might have a quirky TV here. We’ll work towards improving things for you. Please send me a PM and I’m happy to take a phone call to discuss things with you.

With that said: we do not recommend running the GUI at 4K at all. Kodi skins are only at 1080p, so they are scaled. Your TV will likely do a better job at scaling than Kodi.

Your issue was reported on 2nd November, so it will need a bit of time to address this. With any luck we can get it included in the next monthly update (November). In future, for a more expedient response you can open a ticket via the ticketing system.

Cheers,

Sam

I doubt there is anything wrong with the EDID parser. It looks to me like you are using an HDMI input on the TV that is set to a lower HDMI mode (there are various names for it but the maximum you will get is 4k50/60 4:2:0 at 8 bits). We have not been reading that resolution into disp_cap because most (all?) 4k60Hz material is HDR. If you play it at 8 bits you will get banding. Much better to play it at 1080p and 10 bits.

But if you set your HDMI input to ‘Ultra HD’, ‘HDMI mode 2’ or whatever Samsung call it, you should get the full range up to 4k60Hz 4:2:0.

HTH

Hi graham,

How do you get this information? I can’t find any option on my TV to switch the type of the HDMI inputs.

But if I play UHD 60hz material which is HDR the TV shows me a little HDR logo next to the resolution info when pressing the info button. When I play UHD 60hz material which is non HDR this logo didn’t appear. I can’t see any banding on my HDR test clips.

Page 120 of your manual has some information.

I can’t immediately find a menu tree to see where you set ‘UHD Color’.

Oh shit… you’re absolutely right.

The whole thing seems to be my fault, I only can say sorry for the trouble. RTFM…

I found the menu but to find it is like playing hide and seek. Its hidden under “Allgemein -> Externe Geräteverwaltung” (German language) and not under “Bild” (Picture) where all other color and image options are.

Now also the EDID parser offers 2160p60 by default without any custom disp_cap. Beside the resolution another string (something like UHD color) appears now.

I think we can close this discussion and many thanks for your help. But maybe this information are very useful for all the other Samsung users out there and could be a tip in the WiKi.

If I could support OSMC somehow, please let me know.

Best,
