I have had this for awhile now. Played around quite a bit and the stand is top notch quality wise. You can manipulate your screens however you want to.
After much playing around I wanted to try portrait mode. It's great.
But......you need to have screens that are very thin bezel to really be happy. The fact you have 20+ inches of bezel running right down the middle of your screens in 2 places takes up some prime real estate. If you have dialog on screen like choices to be made etc in the Walking dead games it makes them hard to read if your bezel is to big. In landscape no real issues but if Im going to go portrait any time soon I getting different screens. The good news is for my first go round with multi screen setup I chose 23 inch and less expensive models for monitors. I knew I would end up wanting something different no matter what happened. LOL
