Hello, I want to know 2 things:
1) If I connect a 2560x1440p or a 4K monitor to firefly RK 3288 Reload, I can see maximum 1080p resolution in android settings. I cant set it to higher?
2) Can the HDMI INPUT recieve and display 4K video? or for HDMI INPUT is it's max 1080p.
I read on forum that for 4k I need to dsiable dual display.. can anyone tell me how to do it? do I need to build kernel or trhere is a ready firmware for this. If it's possible can you make a custom firmware witrh dual display diasbled and put on the google cloud? would help very much.
thanks!

Hi
1 the max resolution of HDMI IN is 1080P.
2 4K display , there is no such a firmware for you , you need rebuild the kernel with the modification like this:
diff --git a/kernel/arch/arm/boot/dts/firefly-rk3288-reload.dts b/kernel/arch/arm/boot/dts/firefly-rk3288-reload.dts
index 2159526..1a428b5 100644

Isle, thanks for sharing the firmware for it in the other thread!
Are there any plans to release a firefly like the RK3288 Reload with 4K HDMI INPUT?
In general , If I need to connecct a 4K video camera to the HDMI INPUT, and send it to OUTPUT, is there any android box solution sold today that will allow me to do it?
I would order it right away.
