What are you guys even talking about? Both of you speak as if the recontruction tech we have today didn't exist. Not to mention that even plain 1440p in a 4K screen looks more than fine.It is only a issue in 4k TVs or 8k TVs.
The actual content in 1080p TVs sets are fine.
Games really need to introvert render, textures, etc for 4k TVs and it won’t happen with actual console hardware.
PC do a way better job for 4k TVs but it still not there… maybe next generation of GPUs.
I assume you both also only watch ultra HD blu ray as well correct?
