VIC 96 [email protected]
so the TV is able to accept 38[email protected] but it's probably a issue with YCbCr 4:2:2 or YCbCr 4:4:4

any ideas?

Hi,

could it be that all this stuff needed for hdmi 2.0 is still missing in the drivers?
drm cea861 patch
DRI devel Patchwork
CU
9000h
Just add the mode manually and be happy:
Code:
export DISPLAY=:0
xrandr -display :0 --newmode "3840x2160_50.00"  586.61  3840 4136 4560 5280  2160 2161 2164 2222  -HSync +Vsync
xrandr -display :0 --addmode DP-1 3840x2160_50.00

This also can be done via xorg.conf if needed. No the above patches are not needed.
I am despairing. Can't get 50Hz/60Hz to work in UHD. I also connected the PC directly to the TV. No change.

I need support Sad

Then add those modes manually as shown above and retry. Which TV model do you have?
Sony KD-65XD7505

Sorry I ask stupidly. But stress-related I currently have problems with focus.Confused
Can i copy this 1:1? If so, the entry looks for 60Hz would be helpfull

Code:
export DISPLAY=:0
xrandr -display :0 --newmode "3840x2160_50.00"  586.61  3840 4136 4560 5280  2160 2161 2164 2222  -HSync +Vsync
xrandr -display :0 --addmode DP-1 3840x2160_50.00
Just add it 1:1? It's for 50 hz. After correctly added you can switch to it:
xrandr --output DP-1 --mode 3840x2160_50.00
Hi,

I did try this already before, in my case the it's DP2
Code:
xrandr -display :0 --newmode "3840x2160_50.00"  586.61  3840 4136 4560 5280  2160 2161 2164 2222  -HSync +Vsync
xrandr -display :0 --addmode DP2 3840x2160_50.00
xrandr -display :0 --output DP2 --mode 3840x2160_50.00

the modline is added then

Code:
xrandr -d :0 -q

   3840x2160_50.00  50.00
HDMI1 disconnected (normal left inverted right x axis y axis)

but when I try to switch the mode to 3840x2160_50.00 it did fall back to 1920x1080

Code:
[ 40324.330] (II) intel(0): switch to mode [email protected] on DP2 using pipe 0, position (0, 0), rotation normal, reflection none

when I try to switch to 2160p60 it works
Code:

Then something related to your setup - as it works fine for me.

fritsch - are you running with a 586.61MHz rate? If so that suggests you are running 4:2:2 or 4:2:0 at 10 bit YCbCr? Lots of UHD sets will only accept the 4:2:0 8 bit YCbCr mode which runs at the much lower rate of around 293MHz?

Many UHD sets added 8bit 4:2:0 2160/50p and 60p modes using the HDMI 1.4 bandwith limited HDMI 2.0 mode that kept the old clock rates - and don't accept the higher clock rates added in HDMI 2.0 that supports 4:2:2 and 10/12 bit. That could be the issues some are having?


http://www.cedia.co.uk/cda_/images/Resou...er_ENG.pdf Table 2.1 s quite useful - as it shows the two different clock rates that can be used for 50/60Hz.
I don't know what happens internally as currently there is whole lot stuff hidden in the way linux kernel (intel) processes to the output. On userspace side we still compute 8 bit RGBA. But when in 1080p mode I can read my AVRs on screen display. But when being in 4k mode it needs to switch the resolution to render. So there might something going on internally - but nothing I do actively.

Ah - so the 586.61 figure isn't neccessarily the pixel rate (with HDMI 2.0 clock rates go a bit strange as you get more than one pixel per clock) - as Intel drivers 'get in the way'?

Is there any way in Intel drivers of switching between 4:2:0 8 bit and 4:2:0 10-12bit/4:2:2 8-12bit at 2160p50 or 59.94/60? There can't be RGB or YCbCr 4:4:4 output AIUI - as this isn't supported at 2160p50/59.94/60
No way at all. Hidden in the kernel.
I see this in @9000h's post : HDMI max TMDS frequency 300000KHz

I am not sure how 2160p60 can even work if the TMDS clock is limited to 300MHz.

Same here. Sorry I have no idea - not an expert with display modes.
