Question Set custom resolution

[I Mess With Windows]

I have Windows installed on my 2017 iMac 18.2 through bootcamp, playing Minecraft on it and it performs pretty well, I get above 100 FPS, but it lags a little bit when there are a lot of entities. This thing has a 4096x2304 Retina display, and I found that lowering the resolution to 1080P reduces lag a lot, but also looks awful as neither of these calculations 4096/1920 or 2304/1080 gives a whole number. I want to set the resolution to 2048x1052, which is not an option even in advanced display settings.
I am OK with using a third party software for this as long as it is free.
Any help would of course be greatly appreciated.

I have no experience with such apps, but a simple google query spit out the two next websites: http://easyresapp.com/ and https://www.madrau.com/

Seems like both could do what you'd like it to. If that doesn't work, maybe that means they're only preset resolutions. It's possibly to make custom resolutions for external screens, maybe not so much on iMacs..
