so to recap I'm still not able to do 4K60 playback on a RPi4. In Raspbian I can get 4K60 in the desktop environment, but not video playback. In LibreELEC I'm not able yet force 4K60 but 4K30 playback works.

I'll try again in a few weeks.

Here is what tvservice reports in LibreELEC; RPi4LibreELEC:~ # tvservice -s state 0xa [HDMI CUSTOM RGB lim 16:9], 3840x2160 @ 30.00Hz, progressive RPi4LibreELEC:~ # tvservice -m CEA Group CEA has 11 modes: mode 1: 640x480 @ 60Hz 4:3, clock:25MHz progressive mode 2: 720x480 @ 60Hz 4:3, clock:27MHz pr...

Have you tried hdmi_enable_4k=1 ? The last version I tried had firmware that needed that option, rather than the p60 variant. My Pi4 now has both, for when I update the firmware... Do I need to explicitly add "hdmi_enable_4k=1"? I already get 3840x2160 resolutions in both Raspbian & LibreELEC/KODI ...

When uncommented the line looks like; Just in case I get some comments.

You need to add the hdmi_enable_4k=1 / hdmi_enable_4kp60=1 to LibreELEC's config.txt (probably mounted as /flash), the same as Raspbian. For some reason, it isn't on by default in the current build. Thanks. I tried but no dice. I also have tried adding a custom HDMI mode , nothing has worked so far...

The H265 decoder isn't working yet in any Raspbian application. Indeed. Although it is working in LibreElec. (That's just a note for folk browsing this thread). Thanks. I have tried LibreELEC too (suggested to me near the start of the thread). In LibreELEC my monitor runs @ 30Hz instead of 60, so i...

hdmi_enable_4kp60=1 Thanks. Switching back to Raspbian Buster with "hdmi_enable_4kp60=1" added into my /boot/config.txt did make my desktop environment less jittery. xrandr looks to confirm my current resolution and frame rate; $ xrandr --listactivemonitors Monitors: 1 0: +*HDMI-1 3840/600x2160/340...

Use LibreELEC

https://libreelec.tv/2019/06/libreelec- ... ha1-rpi4b/

LibreELEC plays the video but the logging overlay says its maxing at ~30FPS. System settings also say the display resolution of my screen (32UD60) is 30hz. I'll have to investigate a bit, standby...

Thanks, I've used LibreELEC with other SBCs successfully so I'll give it a try.

I've picked up several RPi 4s (2GB models) and I'm trying to play 4K60fps content through them to no avail. I am using Raspbian Buster Full (2019-06-20) and I used apt update & upgrade to get latest. I have tried using several H.265 encoded MP4 video files as well as a few H.264 files. I have been u...

This worked for me, thank you. I'm streaming video from the RPi to a PC in a different room (VLC is being used at both ends).
