I am on the prowl for a monitor I can pair with my Current 27" monitor. I am not too considered about quality of screen, as it is only going to be used for websites, html, and file management. I would really like it to be portrait, preferably able to rotate out of the box (like a stand that swivels). I don't need it very big, maybe 16" and up. but I don't want to spend over 200$ for it after tax. and the closer to 150$ the better. Any incites or suggestions would be appreciated, thanks.
