Hello,
Could you please help to get HDMI 2K Screen (1440x2560) working with Rock 5B and Android?
The screen is https://www.waveshare.com/wiki/5.5inch_1440x2560_LCD, works perfectly fine with Raspberry.
The screen by default requires 206MHz pixel clock that Rock 5B can not set - as a workaround I modified EDID with 198MHz as pixel clock. 198MHz pixel clock works fine with Raspberry, but screen does not work with Rock 5B and Android - even backlight is not turning on.
HWComposer: presentAndGetReleaseFences: present failed for display 0: NoResources (6)
Is observed in the logs (logs are attached - screen connect/disconnect cycle)
