How do you "downsample" an image to look sharper?

Like how some people have screenshots taken out 1440p or 2160p and then downsample it down to 1080p to look very sharp.

How exactly do I do that? I took some shots in Skyrim at 2160p and resized them to 1080, but it doesn't look as sharp as the other resized shots I've seen (actually looks the same as 2160p).

of course it looks the same as 2160p (or worse)

the idea is that itll just look better than 1080p

I'm pretty sure they're doing that in the game itself. If you set the target resolution to something higher than what your hardware is actually displaying it will downsample.

Thanks, I got confused since someone said they downsampled the shot afterwards in photoshop.

Too bad downsampling in-game only works for me in Skyrim, can't really do it in any other games since the checkbox for "display resolutions this monitor cannot use" is greyed out.

Then maybe they are just downsampling the shot afterwards. Are you sure they're actually sharper than your screenshots? Got examples?

Hm, kind of like this where it's insanely sharp.

With Nvidia control panel, you can set up custom resolutions. It involves a little playing to get the optimal sharpness on your screen (depending on the monitor's scalar) and keep it under the proper clock rate. But you basically pick a higher resolution and chose to display it at your monitor's resolution. The resolution is then listed as a supported res.
