I think you mean TMDS is the pixelclock? It's not

I see this in @9000h's post : HDMI max TMDS frequency 300000KHz

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

If the figure is the HDMI clock then HDMI 2.0 introduced the concept of a 1/4 clock frequency.

http://www.cedia.co.uk/cda_/images/Resou...er_ENG.pdf Table 2.1 suggests that 2160p59.94 4:2:2 and 10-12 bit 4:2:0 runs at 148.5Mhz TMDS clock, with 594Mcharacters/sec, as HDMI 2.0 introduces the 1/4 character rate TDMS clock?

i.e. the pixel clock is 4x the TMDS clock when you switch to the new HDMI 2.0 rates?

Where the TMDS character rate is equal
to or less than 340Mcsc, the Clock will run at the same speed as the character rate (1:1). Where the character rate exceeds 340Mcsc, HDMI 2.0 mode will be enabled (in supporting devices) and the Clock will be slowed to just 1⁄4 the character rate;
E.g.; 297Mcsc TMDS = 297MHz Clock 594Mcsc TMDS = 148.5MHz Clock

[fritsch]

Yeah :-) - so all fine?

[wesk05]

Blah I goofed up. I got it confused with the TMDS character rate, because that is what is actually defined in HDMI 2.0 spec and is reported in HDMI Forum Vendor Specific Data Block (HF-VSDB)
Oh! I didn't even notice that I typed "TMDS pixel clock". I guess it is time for lunch!

The Sink Device shall indicate the maximum TMDS Character Rate that it supports in the Max_TMDS_Character_Rate field in the HF-VSDB (Section 10.3.2) if it supports TMDS Character Rate above 340Mcsc and upto 600 Mcsc. The Source shall not transmit at TMDS Character Rates higher than the maximum rate supported by the Sink, as indicated by the Max_TMDS_Character_Rate field of the HF-VSDB

This is with HDMI or DP?

Use at your own risk. LE: /storage/.config/xorg.conf Normal Linux Distro: /etc/X11/xorg.conf - you obviously need the DP (HDMI 2.0) being the connected one.

Hi,

my issue is that 2160p60 is working fine but 2160p50 gives only a black screen on my Panasonic DXW, so is there anyone out there with a similar setup?

I try to find someone who is able to use 2160p50, all reports I'm able to find have 2160p60 but I need 50Hz.

I am able to use 2160p50 - I added the modeline manually and it works.

May be your TV doesn't "like" the GTF timing in the modline. Try a CEA or CVT-RB timing and see whether it works.

[fritsch]

Can you post those @wesk05?

[wesk05]

I can do that later today. I don't have access to a timing calculator now.

Here we go:

@9000h: try the CEA timing first since your TV declares support for VIC 97 (2160p50).

works fine with my Sony KD-65XD7505

but how can get 59.94fps UHD Videos playing at 3840x2160@60Hz. They playhing here at [email protected]

[fritsch]

You won't without adding a 59.94 modeline. I implemented it that way: check 100% matching refreshrate. If that one is found, find a better resolution with the same or better matching refreshrate.

[fritsch]

Thanks very much @wesk05! I will update the default config line.

Can you post another one for 59.94?
