The computer sees the resolution, it has no way of knowing the actual size of the screen. So to the GPU, the 1080p screen is smaller.

What do you mean smaller? Smaller icon on the settings menu? Or it uses 1080p resolution on both monitors?

I never thought of it that way. Is it possible to make my GPU think it's a 1440p?

 

I doubt it. You could set the res to 1440p, though it'll look all stretchy and bleary and yucky. Why do you need them to both look the same size in the display settings?

I don't really care if they're the same size in display settings, it's more that it's out of sync when moving my mouse across monitors, if you know what I mean.

Ooooohhhhh. I don't think there's really a way to do that. There may be, but IDK how. Can you sell the 1080p monitor and save a bit for another 1440p?

I think that'd be my best option right now. Thanks.

or just downsize the 1440p monitor to 1080...

EDID is actually able to include physical dimension data.  Windows 10 uses this to default to different scaling options.
