I also made a picture of the screen, but don’t know how to attach it. It doubles the image in upper part of the screen and flickers in the bottom. Also the colors are strange. I tried the workaround from here https://devtalk.nvidia.com/default/topic/939971/linux/4k-60hz-works-in-windows-not-in-linux-workaround-found-/3 but it does not work for me.
How to fix this problem?
Thank you, Dmitry

I also exported this monitor edid from switchresx running in macos 10.12.6. It seems to be a bit more verbose.

Insert into the sreen section of your xorg.conf

Option "ModeDebug" "true"

restart, then run nvidia-bug-report.sh and attach output file.
If you don’t have a xorg.conf, create one using nvidia-xconfig --mode-debug

Hi, here it is

nvidia-bug-report.log.gz (248 KB)

5

The timings seem to be the same as in switchresx. Does the 50Hz mode work?

6

No, the same flickering as at 60Hz

7

Two things I noticed:
at 50/60Hz, your display only supports YUV 420, is this correct?
Most notable oddity: the driver sets a viewport of 1920x2160 for 50/60Hz modes. Looks like a driver bug. Did you try earlier drivers?

8

Some research done, the Seiki has only one hdmi 2.0 port and two 1.4 ports. From the logs you provided you’re connected to a 1.4 one. Find the 2.0 port.

9

Yes, I tried earlier drivers too. The same result. As for YUV 420 I’m not sure, but under macos it looks like it uses full color space. See attached system info screen

10

I’m using hdmi 1 port, the one that supports hdmi 2.0 for sure. Both windows and os x can run using this connection at 4k@60hz, which is only possible over hdmi 2.0

11

Actually, a subsampling of 420 makes it possible to run 4k@60 over a hdmi 1.4 (speed) link.
Switchresx also talks of 300MHz TMDS clock instead of 600MHz. But it only mentions supported subsampling of 444 and 422. The display is putting out some really contradictory values.
But that shouldn’t lead the driver to set up this weird viewport, which is probably the reason for the strange output you’re seeing. Don’t know if there would be a temporary workaround using some ‘Option ModeValidation’ tweaks to set up an own modeline.
Other than that, did you look for a firmware update for your tv?

12

I have the latest firmware I’ve found in the internet: ATSC_SY15335_SEIKI_V42DK1-QS1_4k2k_CV3393CH_V_11_B1716_20150814. Though it’s 2 years old, I can’t find any newer. If there is no other workaround, I can try to setup a new mode to try it on, if you can guide me on how to do this right way.

Thank you, Dmitry

13

I doubt this will work, but worth a try:
In the screen section, add

Option "DP-0: ModeValidation" "NoVertRefreshCheck; NoHorizSyncCheck; NoVesaModes; NoEdidModes; NoXServerModes; NoPredefinedModes; AllowNonEdidModes;"
Option "IncludeImplicitMetaModes" "false"
    SubSection     "Display"
        Modes      "3840x2160x30" "3840x2160x60"
    EndSubSection

and to the monitor section

Modeline "3840x2160x30" 593.41 3840 4016 4104 4400 2160 2168 2178 2250 +HSync +Vsync
Modeline "3840x2160x60" 297 3840 4016 4104 4400 2160 2168 2178 2250 +HSync +Vsync

and see what happens.

Hi, I tried this and there are no visible changes. I attached my xorg.conf and nvidia-bug-report.log
May be you can find there something…
nvidia-bug-report.log.gz (335 KB)
xorg.conf.tar.gz (966 Bytes)

15

Sorry, typo.
instead of
Option “DP-0: ModeValidation” "NoVertRefre…
it should be
Option “ModeValidation” "DP-0: NoVertRefre…

16

The same result. Nothing’s changed. Please, find attached new xorg.conf and nvidia-bug-report.log

nvidia-bug-report.log.gz (251 KB)
xorg.conf.tar.gz (964 Bytes)

17

Aaaargh, this should be the correct line:

Option "ModeValidation" "DP-0: NoVertRefreshCheck, NoHorizSyncCheck, NoVesaModes, NoEdidModes, NoXServerModes, NoPredefinedModes, AllowNonEdidModes;"

“a semicolon-separated list of comma-separated lists of mode validation arguments…prepended by colon-separated display identifier”
Edit: and again forgot to remove the DP-0: at the beginning.

18

With this settings the system doesn’t boot at all. I have to reset graphics to default to let it boot.
The log and config are attached.

Yeah, forgot about this bug:
[url]https://devtalk.nvidia.com/default/topic/898310/linux/352-63-regression-quot-noedidmodes-quot-breaks-custom-quot-modeline-quot-modes-ubuntu-14-04-/2[/url]
Wrong mode due to bug, workaround not possible due to other bug.
Just delete the Option ModeValidation line. I think the custom modelines will be filtered out.

20

Does that mean, that there is no workaround possible at the moment?
