For instance, I first tested on 3 monitors (my personal rig), two LCD's at 1280x1024 and 1680x1050 (native resolutions) and a CRT at 1600x1200 (maximum resolution). Because the maximum horizontal resolution allowed is 3840 for three monitors, this setup was already over 700 pixels over. The vertical maximum is at 1200, which we can't reach since vertical resolution is based on the lowest common resolution, meaning 1024 or less.

That means it's alright to have a monitor that does 1440 and 1680 across, so long as the vertical resolution is consistent with every monitor. If they don't match correctly on LCD's, you'll effectively have one or two very ugly looking screens while one looks just right. For CRT’s, it just means a portion of the screen won’t be used. This happens anyways with "Bezel Management," which readjusts the displays to properly show the image on screen and not make the bezel, or the outside of the monitors, ruin it. And that system has so far been flawless by our testing.
