I currently got a 3840x1080p super ultrawide monitor. In games like AC Odyssey, I still play on '7680x2160p' by having dynamic resolution on 200%. This looks way way better than just 1080p. So I would only assume it would look even better on an actual 4k monitor / 2160p monitor.
Now, I have experienced that lowering resolution (actual resolution, not dynamic resolution, while keeping the aspect ratio) on a 1080p monitor to 720p looks disgusting, while on a 1440p monitor -> 720p it still looks 'acceptable'. I get that, since 1440p/2=720p fits the amount of pixels better.
So this got me to my question... Is that the same with dynamic upscaling?
1080p -> 2160p dynamic upscaling looks lovely, but will 1440p -> 2160p dynamic upscaling also look good?
(which should of course look even better than the 1080p monitor, since its a 1440p monitor...)
Curious on how this technology works.. if the native is completely irrelevant for the dynamic resolution, or not.
