The reason for skipping 1080 @ 25/29.97/30 is interlaced content which needs the "double" refresh rates to render (Kodi always outputs progressive) but there is no interlaced broadcast 4K media so you don't need to do the same thing. So whitelist whatver 4K modes are visible.
Hi,
so that means i add all available modes for 3840x2160p in my whitelist?
Is it worth to set Kodi menu to 3840x2160p with 60Hz ?
Hi there,
on my fullHD i add following resolutions to my whitelist:
1920x1080p - 23,98 Hz
1920x1080p - 50,00 Hz
1920x1080p - 60,00 Hz
Libreelec/Home Menu is 1920x1080p with 50 Hz.
All works fine.
Which resolutions should i add to whitelist with a 4k tv? Same like 1080p?
3840x2160p - 23,98 Hz ?
3840x2160p - 50,00 Hz ?
3840x2160p - 60,00 Hz ?
And is it worth to set the home menu to a 4k resolution?
i remeber that chewitt give a recommandation but i dont find the thead.
Thanks ins advance!
Here's a new testbuild with HEVC decoding fixes: LibreELEC-RPi4.arm-9.80-devel-20210210171544-68ac68f.tar
Some HEVC files showed pixelation artefacts (decode errors) and the "Samsung Wonderland Two" demo from 4kmedia.org resulted in a hard crash because the decoder ran out of memory. The HEVC decoder now handles out-of-memory situations much more gracefully and we've increased the default CMA memory size to 512MB so the file can be properly decoded.

Hi HiassofT
is that part of the newest nightly image?
Display MoreJohnWayne111 just talked to RPi devs but you might not like the answer:
RPi4 doesn't have hardware support for HDR-to-SDR tonemapping, it might be possible to tweak things a bit but the result will always be off - either too dark or too light.
Simple solution: don't use HDR encodes if you don't have a HDR display.
You could also try to re-encode the HDR files on your PC, ffmpeg (and probably other encoders) should support that with tonemap filters (never used that myself though).

Hi HiassofT
ok, what a pity!
But, and really NO JOKE, my neighbour bought a 65 inch Sony Bravia and dont need his 55 inch model from 2017 (Sony Bravia).
This TV has 4k and HDR Support!
And the best - i get it today for nothing! LOOOOL 
JohnWayne111 HDR to SDR tone-mapping is a completely different beast, purpose of these testbuilds is to check if true HDR output works fine.
so long,
Hias
Thanks for your reply HiassofT
I will wait
Hi HiassofT
is there an option watching 4k HDR Files with an full HD TV with non-HDR?
Will there be with this new release a correct color representation?
Is there an option to get the correct color represntation with a Full HD Tv which has no HDR ?
Or is this not implemented yet? (just a question)
I test this build with my Full HD TV (Non HDR) cause i want to know if HDR files has correct color representation.
Cant get a feedback, still hope in future it is possible 
THANKS ALL for your good work!
Let's see after the team call
Hi chewitt
any news about this?
"Just" nightlies or offical alphas/beta LE 10 releases ?
Tanks, but im confused. Reason:
Current plan is to release official Alphas for RPi4 along with the other Alpha builds.
RPi2/3 releases will probably follow later as there's a major issue in the video driver (screen going blank). Once that's fixed RPi2 alpha builds will follow.
so long,

HEVC has been working for months (H264 is/was the hold-up). 4K is working now (not 4K60, but that's will be along eventually). HDR is complicated but will come. Upstreaming will take time.. but getting it all working comes first. We aren't going to do a formal Pi release for LE10 out of an abundance of caution (we have hundreds of thousands of Pi users) but things are moving along nicely..
HI chewitt
i guess its time for a offical Alpha LE 10 version
Will LE going on a another release strategy like only nightlies and then final version?
Or will there be "official" Alphas and beta releases?
Well, write speeds sure are better on a SSD than on a SDcard. And they last longer, I've binned a couple of SDcards in the last 2 years.
I'm using a Startech.com USB3/SATA cable adapter and an almost 12-yr old prehistoric 60GB OCZ Vertex 1 (sata II) SSD.
60 GB for LE !? 
16 GB are enough? Why so much?
Hi Klojum
ok, i switch from SD Card to USB 3.0 Stick with latest Pi4 Firmware.
That was worth!
Can i expect more speed from a USB 3.0 Stick to a SSD ?
It this worth Libreeelc on a SSD ? Which one do you use ?
Ok, thanks four quick response.
I can wait. I have a full HD TV and im more interested if there an general technical way on Pi 4. (HDR to SDR)
