Thanks for this. This brings up an option to set the Mode.

I have a Samsung 65 Ultra HD, 3840 x 2160 pixels so presumably there is a benefit in setting the Mode to 2160p and resizing the OSD Position to fit, rather than just leaving it on 1080p which doesn't need resizing?

Is this just a better scaling option or is there any picture quality improvement? Hard to tell visually

Cheers
