How bad will a 1080p signal be on a 1440p Monitor?

Hi all,

Thinking of buying a 1440p monitor for my mac mini and raspberry pi 4

How bad would a 1080p signal look and 720p ?

Currently have a 32'' 1080p monitor, and is very old only has one dvi
connection

Thank you in advance

If monitor has DVI, dual link DVI can do up 2560x1600 at 60Hz.

Thank you, but how does that relate to my question ?

Mac Mini should be able to do monitor's native resolution even if DVI is its only "modern" display output.
(assuming monitor has DVI)

Rasp Pi 4 doesn't even have anything other than 4K capable HDMIs.
So assuming software isn't screw up, it can do 2560x1440.

i know that, i asked what would 1080p look like on a 1440p monitor
The pi 4 has a max of 1080p
i only have a 1080p monitor, but would like one with more connections on it , my mac mini max res is 1440p (its old)

No it doesn't

Pants, modern monitors with fixed pixels (LCD, OLED) will never look great with lower res signal. Buy a monitor you can drive at the native resolution.

What are you doing on it? One exception could be if you're just consuming video or similar, then scaling may not be too bad, but if you're reading text or games and sat close to it, then you want native res.

retro games on the pi and general computer work on the mac, i sit about 1 meter away

I had a 32" 1080 for a while to play retro RPGs and because of the really poor pixel density I'd prefer to use any other monitor on the planet at any res than suffer that again.

Do you mean a smaller monitor ?

Went 1440 32" and ran it at native res. Eventually went 4k 43", was fine with both.
For 1080 I'd want smaller, I've got a couple of 24" 1080 monitors which are ok.
