That is damn fine, lovely set up.
Thanks
^^ Very nice indeed! I've always had mine in landscape mode, never even thought of going portrait due to the thick bezels on my monitors. What cards are you using to drive 3 monitors like that....
Portrait mode is insane, even more with debezelled monitor, but one of mine is a TN panel, while the other two are IPS panel
in landscape it's fine because the horizontal angle on TN panel are good, but in portrait mode the (originally) vertical angle turn out to be the horizontal angle now, which mess up the screen unless you sit right in front of it.
TV Show, movie are strange to watch when the actor's faces gets right between two monitor (even with bezel correction).
Also, 23" might be a little bit narrow for portrait surround, maybe 27"+ should feel better.
