A:Answer I'm not clear on what you're asking. If you've got a 1080p set, then games (and video) are of course limited to 1080p.
Going forward, PS4 games are going to be enhanced when run on the Pro. It's up to developers how they want to take advantage of the extra power. Higher resolutions is one possibility, but not the only one. There could be smoother framerates, more physics, more graphical detail, etc., and of course all that WILL show up on a 1080p TV.
