Will this look ok?

One potential issue I see is that your center, main monitor appears to lack VESA mounting holes to attach a different stand to. You would likely need to add an adapter to allow the monitor to attach to third-party stands. Something like one of these, for example, though you would want to verify that the bracket works with your particular model...

Of course, it's possible that you might be able to skip getting a stand entirely if the height matches up relatively close between the screens.

Also, the second page you linked to is for their KA series of monitors in general, which includes multiple monitors in various sizes. One thing worth noting about them...

Also, the second page you linked to is for their KA series of monitors in general, which includes multiple monitors in various sizes. One thing worth noting about them though, is that while your center monitor has very thin bezels, most of those screens appear to have more typical, wider bezels. The exception might be this model, which appears to also have relatively thin bezels, though you would want to verify that...

Having thin bezels would obviously be better if your intention is surround-gaming across multiple screens.
