Portrait/Landscape Monitor Orientation

[mbcollins93]

I built a pc with the help of toms hardware two years ago, and I am now wanting to buy two monitors for it. I want to buy two monitors and try a P/L orientation. I am currently looking at the ASUS VS239H-P series of monitors. They look like the best IPS monitor for the money. ( I am up for suggestion though. My only requirement is that it have HDMI and be 16:9 for xbox.) My question is, what size is best for portrait orientation? I mainly want to use the portrait monitor for web browsing and coding. Thanks a bunch!

The ASUS VS239H-P comes in 21.5 and 23. So, I was thinking 23 landscape and 21.5 for portrait, or a 23 for P and another 23 for L. If another size is better, I am up for a recommendation of another series of monitor.
