What would be best if they’d just render the green part, at the native pixel resolution of that green box and then transport that. However I guess that’s not possible due to the scaler for example. This would have resulted in a much better picture quality for the 8k. Also it would have increased performance BIG time.
Thinking of this, why not just kill the scaler in the 8k? Then again, they’d probably need custom hardware to map that green box to the panel?
