It's GPU scaling of the output, it doesn't care what is at that output. It works all the time.

4k=2160p is 2 times 1080p for scaling purposes. Obviously an area of this has 4 times the amount of pixels.

An nearest neighbor scaling at whole number scale will have no issues other than loss of resolution. If you want to you can use better scaling algorithm and actually have better than native 1080p output that is smoother thanks to supersampling.
Some GPU drivers now offer the whole number scaling, as useless as it is for 99.99% of people.

TVs can have crazy post processing including scaling to deal with all the low quality and low resolution sources. On PC you deal with it on GPU using your video player and renderer.
Monitors are made to show what is sent to them, not to add tons of rubbish effects like TVs that can't even be turned off at times. Though monitors in the "gaming" part of the market do tend to have some of the crappies firmwares with added undesirable effects at times, usually they mess with sharpness and don't even let you change it back to neutral but there can be more than that nowadays on some of the gaudy models.

Want 4k TV, just get a 4k TV.

I said why go down to 1080 from 4K. You can watch 1080 vid at 1440 or even at 4K.

You can go down to 1440, and again, not suffer any IQ, especially in games. The screenshot may not represent actual IQ but you'll get an idea about the difference in text and icon sizes (left side is 1440 and rt side is 4K).

Wow I did not know that. Is there a any down side to running 4k at 1920x1080 besides resolution?

skupples isn't that the main difference between TVs and monitors?

i'm no expert here though.

I typically use the custom resolution setting via NVCP, or in-game scalers if I need to drop below 4K for some reason. Either way, its always going to introduce some amount of blur... thus where driver level, or monitor HUD sharpening come into play.

I wonder why there isn't a Star Wars - Jedi: Fallen order QQ thread? It's an even hotter mess than RDR2 was. Stutter city. Is the subject matter just too holy?
