The HDMI output seems to be left shifted. The leftmost pixel is not displayed on my screen:

Hi xypron,
This problem is caused by the resolution scaling which makes the resolution from 540p to 1080p. We have some imporvements which are under testing. If you want to have a try, you can change there files:

  1. Change the header file: 'include/video_eswin.h'
    #define DRM_ESWIN_FB_WIDTH 1920
    #define DRM_ESWIN_FB_HEIGHT 1080
  2. drivers/video/vidconsole-uclass.c, in function vidconsole_putc(), add below code before video_sync().
    #ifdef CONFIG_EIC7700_RISCV
    return;
    #endif
