Problems with video output by HDMI

Hi guys! Using the keyboard and mouse from the Black Shark via an HDMI cable, while playing games, the control rotation is set incorrectly. The mouse and keyboard reads the screen as "portrait mode". Which is accordingly impossible in games. What should I do?
Black Shark 3 Pro + JOYUI 12.5.21.08.27 + Black Shark One Hand Keyboard + Black Shark Mako M1
Cable : Deppa USB Type-C - HDMI, 4K, 60Hz
The control works, but by turning the mouse to the left, it turns up, etc.

I have the same issue. Keyboard mapping doesn't work correctly when connected via HDMI. Were you able to come up with a solution?

No, official support is not responding. I want to try to buy the original Black Shark HDMI cable.
