Update 7: Altered name of topic to be more descriptive. Reorganized sections and adjusted wording to fit. Minor change to formula in nonperpendicular multiview section to reduce complexity.
The main post has gotten extremely long, so I decided to move some of the more complex sections to their own posts to free up space. Hopefully it will be easier to find stuff.

Re: Finding the Mathematically Correct FOV & Multimon Settings For ANY Monitor Setup
Minor update: Fixed a flaw in a formula that was overlooked. Related diagrams updated to include more appropriate variables.
Explanation: I found a problem with the way I was calculating the FOV of nonperpendicular monitors. Simply put, the method I was using previously only worked if the monitor was angled more outwards, i.e. closer to a parallel setup. It would fail (give the incorrect numbers) if the monitor was angled more inwards, to create a more boxedin setup. The changes affect the nonperpendicular multiview and the universal formula sections. Unfortunately, it has made calculations a bit more complex where affected, as there is an additional "IF THEN" statement now, and an additional variable to compute. I hope my mistake didn't cause too much trouble, although given how mathheavy and niche those two sections are, I'm thinking very few were affected. Anyways, for the few of you out there with boxlike setups, my formulas should actually work for you now. Hopefully.

Update 8: Added reference to new calculator I'm working on; will be periodically updated to give better information. My setup has since changed, so the example pictures and videos have been updated and improved. Other small wording changes and a small addition in the miscellaneous info section.
