After fiddeling with my TV's UHD settings - for me 4k@60 and 4k@50 works without any additional changes. So not sure what we fix here :-)

Out of the Box with LibreElec?
Get this not working with my config
Pioener VSX-930 with Sony KD-65X7505 UHD TV. Only 30Hz at 4K.

EDIT: Note for myself.... RTFM Found some infos in the manual. Will test it tonight.

I have a denon avr-3300x and LG Oled B6 and not get 4k@50 hz if not add manually the modeline

[fritsch]

On my Samsung I enabled uhd for hdmi1, rebooted and had 4k@60 and 50,24,23,30,59.94. A Denon AVR is in between. I used Standard HDMI 2.0 capable cables, cheap ones from Amazon Basic.
Sidenote:without setting the tv up correctly it did not even accept 4k 50, 60 manual set xrandr modes.

I can provide my edid to overwrite yours if needed.

I have LG oled B6 with UHD enabled in HDMI2 and the denon 3300x between, my cable is from amazon too https://www.amazon.es/gp/product/B004BEM...UTF8&psc=1 get 4k@60hz withouts problems.

If you send me your edid i can try load in boot with your manual and send my xrandr modes

PD: I really happy you adquired one J4205! The case mtech is beatifull, i have one origenae s10v and only replace the motherboard and hdmi cables, If I did not have the originae would buy the mtech

Here the howto: http://forum.kodi.tv/showthread.php?tid=...pid2479154
Here the edid: https://dl.dropboxusercontent.com/u/5572...non-4k.bin (256 Byte in size)

If you follow the howto correctly (and use Ubuntu), you should end up with that in /etc/default/grub:

Code:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash video=DP-1:1920x1080@50D drm_kms_helper.edid_firmware=DP-1:edid/edid.bin

And the kernel should tell something like that:

If you use LibreELEC, you can find the howto in the linked thread.

Edit: I run the TV in 1920x1080@50 as I mainly watch LiveTV 1080i50 and let that upscale by the TV. For (rare) 4k@Whatever content kodi automatically switches up.

The issues with 2160p50 and 2160p59.94 couldn't be related to 4:2:0 vs 4:2:2 / 4:4:4 compatibility could they? I know some displays only accept 4:2:0 at this resolution and frame rate, as they are still using the lower bandwith HDMI 1.4 physical hardware which can just about handle 4:2:0 at 2160p50 and 59.94, rather than the higher bandwith (optional) modes which add support for 4:2:2 and 4:4:4 at these frame rates.

AIUI this is one major reason that a 4:2:0 mode was added to the HDMI 2.0 spec, and meeting it is enough to be considered HDMI 2.0. (And given that pretty much all consumer video is, and will remain, 4:2:0, the only major issues is for UIs and Photo-type display applications, until you need 12 bit for HDR. Not sure if 10 bit is supported or not)

I have to add something, the 50p mode is missing for me ... while the 60 is there. I created an xorg.conf that adds it on top. Until I like to alter my edid.

So you cant get 50p neither with your edid?

It seems besides the 60p - the EDID contains nothing ... I looked in the 1080p line when I thought all is there.

Does 4K Netflix work on Apollo lake under Windows 10 / Edge browser ?

It works at 4k in the app, it doesn't work in the edge browser. Also, there was some choppyness during playback even though the CPU was only at 25% or so. Not sure what caused it, i only tested for a few seconds.

System is up and running:

Case: http://geizhals.de/ms-tech-ci-70-a725798.html (63 Euro)
Board: http://geizhals.de/asrock-j4205-itx-90-m...25586.html (120 Euro) alternative: http://www.mindfactory.de/product_info.p...25605.html (90 Euro)
Memory: 2x http://www.mindfactory.de/product_info.p...14925.html (50 Euro)
SSD: https://www.alternate.de/Transcend/TS16G...ct/1171310? (30 Euro)
Sum: 263 Euro or 233 Euro - fully silent.

One thing that is missing is VP9 Profile 2 support. But hey (consider the 200 rule), meaning the core components (Board + Memory) < 200 euro as you can keep the case and the ssd.

Edit: For now I think you can also savely go with a 3445 version of the board and save another 30 euros.

The case you linked to is fantastic, I was looking for something similar available in the U.S. but am only able to find a "Thin" mini itx from silverstone and I do not think the board will fit.

Has anyone come across a good case option for this board in the U.S. with an external power adapter?

Thanks, not sure how I missed that. Searched pretty good I thought. Quite a bit pricier though.
