Question Acer Nitro XV272UP has a 5120x2280 resolution option in windows

[Rajivrocks]

So I bought a Acer Nitro XV272UP to go with my new RTX 2070 Windforce card. I installed the monitor today and its amazing. I got one question though, when I go to "Display" in the windows settings you have a drop down menu to select what resolution you want, seeing how its a 1440p panel 2560x1440 is the standard res and it says recommended next to it but, you got one option above that as well somehow that says 5120 x 2880, but what is this? This is a 1440p panel, is this windows being janky?

Here is a link to a screenshot of what I mean.

Hope you guys could shed some light on this, because on my other screen screen next to this one (my old primary screen) it shows me 4k res (its actually a 1920 x 1080) so 1080p would be "recommended" like in the picture above but 3840 x 2160 would be above that. So I guess its a windows bug? Because there is no way my old screen was 4K x)

Check if dsr is on in nvp.

Oh it probably is that, Where is this setting though, cuz I can't find it. I see the resolution in NVIDIA control panel under, "adjust resolution"

You have DSR 4.00x enabled in the NVIDIA control panel.

Manage 3d settings > DSR - factors.
