Hi @Andrey Zorkin
The resolution you are trying has a couple issues. It is not a “Standard” HDMI resolution. This doesn’t mean it can’t or won’t work, but it certainly hasn’t been tested. I did post some hints about what resolutions have been tested, and where the source code is located HERE.
Having said that, the hardware it may well work, just not tested. The HDMI output is generated by a MIPI-CSI to HDMI bridge chip (ADV7535), the actual MIPI-CSI output on the 410c chip is fully capable of generating 1920x540 native resolution. There are hints on how to program the MIPI-CSI output HERE
The other issue is the Android operating system (the higher layers above the device driver), again your resolution has not been tested, and again it may work, or it may require some patches. There is some more information about the Android display system HERE.
Hope this helps.
