Monitor Recommendation - Portrait Orientation Next to ASD

[southerndoc]

I have an ASD, which I absolutely love. I'd like a little more real estate. I keep a Messages window open all the time, and would like a side monitor to display Messages and a few other smaller things.

I want something that in portrait mode would be about as tall as the ASD. No need for audio, webcam, etc.

Anyone have any suggestions for monitors they like that would fit the bill?

Thanks!
