RK3328 : Not all HDMI modes works #19

Closed Kwiboo closed 4 years ago

Kwiboo commented 7 years ago

With the changes in latest kernel update the ROCK64 device started to report 4K60hz modes, but not all modes reported seems to work.

For 1080p only 60hz works on my Sony KD-65X8509C TV. 50, 30, 25 and 24 hz do not produce any picture.

All modes (including above) reported on my Tinker Board running same kernel work using same HDMI-port and cable.

I will check it. Please check the /sys/class/display/HDMI/debug node info first, and provide it to me.

check this node : /sys/class/drm/card0-HDMI-A-1/debug

857041e.diff.txt Please use this patch to test again

Kwiboo commented 7 years ago

@yanghanxing thanks!, that patch solved my issue with 1080p modes, but there is still an issue with the 4k 50/60hz modes not getting signal. Will update this issue once I have had time to test more.

LongChair commented 7 years ago

I can confirm what @Kwiboo mentioned above, Any mode starting at 3840x2160 with frequencies starting at 50Hz don't display anything (No Signal). tested it with 3840x2160@60 and 4096x2160@60 ->No signal Both 3840x2160@30 and 4096x2160@30 will work fine.

Koloss78 commented 7 years ago

In Android i can activate 3840x2160@60(50) and 4096x2160@60(50) but not in libreelec

Kwiboo commented 7 years ago

@Koloss78 please note that this is not a LibreELEC issue tracker and as noted on https://github.com/Kwiboo/LibreELEC.tv/tree/rockchip/projects/Rockchip/devices/ROCK64 supported 4K modes have been limited to 24/30hz, mainly because of the kernel issue reported here.
