Dumb question about screen resolution

[Cappuccino]

I have a 1440p monitor.

1.) I download 1080p desktop wallpaper - Will I see the picture in 1080p or 1440p? And how do I know if the picture is 1440 or 1080 or even 4k?

2.) I download 4k wallpaper will I see the picture in 4k or 1440p?

3.) I download 1080p or 4k pic will it just automatically convert the wallpaper to my original resolution which is 1440p?

Dunno why this is confusing I am curious and would liek to know the answers

I am dumb. I like small cats.

a) Depending on how you set the background picture to show, you'll either see it upscaled to 1440p ("fit", "stretch" or "fill" modes), or at 1080p with a border ("center").

b) Either open the picture in a program meant for viewing pictures and view the metadata there (in Windows 10's Pictures you right click the image and click "File info"), or right click the file, open the file properties, and click the Details tab. Resolution should be under the Image heading, not quite at the top.

c) See a). Center will show you a cropped full resolution image, the others a shrunken version.

d) Yes, if you choose the correct settings. See a).

No questions are dumb. Not asking questions is what is dumb
