Formula for screen aspect ratios

[SpaceBeeGaming 3]

Hi, I'd like some help with calculating the aspect ratio so that the whole in-world screen is filled. Like having 4 wide and 3 tall screen and have it filled. what if 3 wide and 2 tall?

I gave this a whirl and it proved to be a bit more challenging than I thought it would be, and I'm not really content with it.

It works to a certain degree, works better for some ratios than others and whatnot. I couldn't seem to find an algorithm that would work properly.

I tested with all tier screens and a tier 3 graphics card. It should work with tier 1 and 2 graphics cards as well.
You can run monitor.test() and break/add some screens to see it in action.
If there's any code you're wondering about, feel free to ask 

Edit: It feels like it should be a lot simpler but idk

@Slamakans You can use gpu.getResolution to get the currently set screen resolution. It returns two numbers. That may simplify your code a bit.

I'm taking into account the max resolution based on the screens as well, not sure were you think I should use that instead of something else?

The current resolution doesn't matter much since I'm setting the resolution anyways. If you mean that I should use it instead of monitor.getResolutionFromTier, I guess I should've named it getMaxResolutionFromTier cuz that's what it does

 

Forgot to say that monitor.fill() would be what you'd use to fill the screen but maybe you got that

 

Edit: I forgot that gpu.maxResolution() returns the lowest of the two. A bunch of the code can be removed if that is used instead: https://pastebin.com/1jtwLRQA (untested)
Amazing how you never learn not to code when tired af
