[SOLVED] Virtual display software

[DynV]

Unfortunately my display has a lowish resolution (1600x900 px) and I'd like to screenshot something at a higher resolution; if I had a friend with a 4K display, I'd ask (but I don't). I'm wondering if there's a free software to do so (either as in freedom or as in no cost), which is what I think is called a virtual display (perhaps it's a real term?). If there's no such think or it's too complicated to set up, I'd like the following.

I can't get a large enough version of http://www.google.com/maps/d/viewer?mid=11nyC6TX49v1JL-t2VblCTyPwlFrmDkrK in a screenshot. The biggest I made was by making my display in portrait mode but it's small; I've added red lines near the corners of what I require to be in the screenshot making

If someone with a large resolution would kindly zoom as much as possible so *all* the required area (within the red lines) is included and is as close as possible to the distance indicator (currently at the bottom) ? The sidebar is not required; one may hide it in its header 3 vertical dots (clicking on it) then Collapse map legend.

I used DSR on a 1080 display,hope it's good enough.

Yes, thank you again.

I used DSR[...]

The only results from "DSR software" seem to have nothing to do with image scaling or display manipulation (including GPU manipulation). Could you let me know what it is so I don't need to rely on someone else if I have such an issue later?

It's from the nvidia control panel ,Dynamic Super Resolution it let's you play games at 4k on a 1080 screen,for whatever reasons I don't get it either,but it's fun to play around.
