So, its fine to leave the resolution in the screenshot settings on the Pro at 4K?
Does that technically mean when viewing them on 1080p, there supersampled down? Or do we need to use a program to do that?
Just want to make sure before I go on a screenshot binge I have the best settings.
Sorry, I've only just seen your reply.
Bear in mind that when I'm replying that I'm replying in general terms and that there may be games that have specific modes or differences in the way that they handle the different resolutions.
How are you showing the images on your screen? Are you landing them on a PS4 or something?
I've not really messed around with screenshots on the Pro yet but in the options menu it gives you the choice of capturing them at 1080p or at 4K and irrelevant of the screen that your playing the PS4 Pro on, the image that they capture will be identical. There will be nothing to differentiate them because they're taken from the raw image before the PS4 sends it out to your screen.
Forget about the screen being used when taking the screen shot as it has nothing to do with the screen shot at all. Nothing.
What ever method you are using to test these on your PS4 you do not need to do anything to them until you're viewing them. Clearly, a 4K image is going to be too big for your screen so you'll need to zoom in the app that you're using to view them so that they fill the entire screen.
If you do that, what you will see is the same as what you would see if you were playing the game on your Pro. The only differences that you may get doing that is that if the app you're using to display or the hardware that you're loading it onto to display on the screen may not handle "downsampling" as well as the PS4 Pro does through summer sampling. If that was so I would imagine that difference in quality isn't going to be noticeable unless you have your eyes against the screen, if at all.
If anything, the quality will be slightly better when the game is running live on the PS4 Pro rather than doing it in the way you want to sample these shots but you will essentially be seeing exactly what you would be seeing if you were playing the game yourself.
I hope that helps?
EDIT:
I'm probably pointing out the obvious here but I should add that if you are using images taken in a photo-mode, some games add additional processing to those images which will make those images look better than raw gameplay. If you use one of these screenshots then what you'll see is the same as what you would see in the photo-mode of that game rather than in raw gameplay.
