Green border in CE9

Hello,

I have a green border (top and right) in the screen:

The only way to fix it to enable “Use 4:2:2 colour subsampling”:

Why it is happening?

Regards.

That to me looks like overscan, maybe you need to calibrate your display.

Thanks adamg,

Where could I calibrate the display? In the Kodi setting or in the TV settings?

Kind regards.

TV Settings. Calibrating in Kodi is last resort.
