Resolution and FOV calculator

This tool can be used to calculate several things, allowing you to find either FOV, aspect ratio, or resolution.

 

Calculating resolution with aspect ratio

 

You can calculate a desired resolution using an aspect ratio. Simply enter the aspect ratio (or calculate it using field of view) into W1 and H1, then enter either a height or width in W2 or H2, and it will find the other respective value using your aspect ratio. This is useful if you want to play using a specific aspect ratio in windowed mode, but you only want to use a set height or width on your display.

 

Calculating FOV with aspect ratio

 

Halo calculates vertical field of view based on your horizontal field of view and your aspect ratio. Normally, only your aspect ratio can be changed. Horizontal field of view remains set to 70 degrees, and this results in your viewpoint appearing zoomed in when you switch to an aspect ratio that is wider than 4:3. Fortunately, HAC2 allows you to set your horizontal field of view. However, if you do this, you then change vertical field of view. If you want to keep your viewport from appearing distorted while taking advantage of your wider aspect ratio, you will need to find a horizontal field of view that works with the stock vertical field of view at your aspect ratio. Here's a GIF that shows you the optimal horizontal field of views for Halo's default vertical field of views for a few aspect ratios:

What if you find Halo's default vertical field of view to be a bit narrow and you want something a little wider? You can also choose the slightly wider Xbox field of view as well as specify your own vertical field of view ("Custom") if you want to customize it further. Then you can set your FOV using HAC2 to the horizontal FOV given by the tool and you will get the vertical FOV as well.

 

Calculating aspect ratio with FOV

 

This feature is a little advanced but provides you the most control over your field of view. Enter your desired vertical and horizontal field of view and you can calculate an aspect ratio that will give you those fields of views. You can use this ratio to calculate the resolution you want to use to achieve this field of view. When you have your aspect ratio set up, set your FOV using HAC2 to the horizontal FOV given by the tool.

Tiddy-bits:

I've uploaded the HTML file for download if people want to include the calculator on their website without having to save from a web browser or use tools like wget or curl.

A few people have noticed that Halo increases the field of view very slightly when you increase the resolution. I'm not sure how much it does this, but I thought it'd be worth pointing out, as some consider it game-breaking due to how they exploit grenade tricks by using the HUD and the geometry as a reference.

 

To reiterate, this is not a problem with the calculator, but a problem with Halo.
