Hello everyone. I have a x96max+ tv box(s905x3,4G ram
64G rom) with android 9.0 and coreelec nightly on it，andriod on the emmc，and coreelec on the sandisk high speed tf card. But I got “no hdmi signal” when played a 4k@60fps video,which played well on the android.
By the way,I have another s905d tv box(coreelec 9.2 stable version) ,it plays the same video very well.

It could be a few things, but I would suggest you try the cable. In android it normally outputs at the GUI frame rate, In Kodi it will try to output at 60Hz which is a much higher bit rate and your cable may not be up to it. When you are playing it back in android press the info button on you TV and find out what mode your TV is @ when playing back under android.
thanks for the reply.I use this HDMI cable to connect my computer and TV,then playing same video(4k@60fps，via potplayer) ，everyting worked ok.
When I use this HDMI cable to connect my tv box and tv ,and try to play the 4k@60fps video via KODI,the signal lost… ,so I think the cable may be ok.
Not necessarily. The video signal has another properties like bit deph and chroma upsampling which could be different. CE tries to send the best signal which needs bigger bandwith which maybe not supported by your cable.
You can try to limit the signal to 8 bit and 4:2:2 in CE settings.
Also you should set up your tv if it capable to show of HDR video.
yes,I rebooted. I just turn VESA on (setting - coreelec - hardware - display),and turn off the 4:2:2 setting,and reboot the box,then I found the resoution of kodi CAN BE set to 2160p@60hz,but the hdmi signal still lost when playing ANY videos…then I think I should turn on the 4:2:2 setting ,after rebooted the box,I got a “no signal” screen after the coreelec boot screen.
What does the VESA used for?Is it the key-point?
Sorry about my poor english.
How’d you get to the hdr and vesa settings? I’m having the exact same problem, setting the UI to 4k causes the signal to fail, and playing 4k 60fps videos does the same.
I’m using Coreelec 9.2.1 stable on a Beelink GT1 standard, 2G I assume (if not fake).
EDIT: Figured it out, toggled the 8bit limit and 4:2:2 settings. 4k 60fps video now works. Didn’t realise I had to restart for the settings to take effect. Unfortunately the UI is limited to 2160p @ 30hz. I’ll change the cable.
