TL;DR : if you want to mount monitors vertically side-by-side, try before you buy.

One thing to watch out for if you install two vertical side by side monitors is that many monitors (especially gaming monitors) are optimized to be watched horizontally.

That sounds weird, so let me explain:

LCD's have a sort of a "field of view": if your watch them straight (at 90 degrees), the amount of light reaching your eyes is maximum. If you look at them sideways (eg 45 degrees), the amount of light that reaches your eyes decreases (this typically happens when you look at a co-worker screen while sitting next to them).

Good LCD's have a wide field of view: you can look at them from the side and still see a good image.

But the expectation is that you will watch them from the side, not from above or below, and manufacturers have taken advantage of that fact: they optimize for a wide horizontal field of view, but the vertical field of view is, on some monitors, terrible.

It does not matter unless you mount the monitors vertically, in which case the vertical FOV becomes your horizontal FOV, and you might not even see the image on the outer edges of the monitors.
