Hi David,


Apologize for the delayed respond.

I understand that this is not a bug.

Only active video frame is stored in frame buffer.

For example, when Htotal = 4400 Vtotal = 2250, only H-active = 3840 and Vactive = 2160 data is stored in frame buffer. The size of a frame in frame buffer is 3840x2160x byte of a pixel.


Thank you.

Best Regards,

Zul
