This is the monitor I recently got, my budget and desires were pretty much the same as yours. Its 1600x1200 and can turn vertical or horizontal, its also on a swivel so you have alot of control over the position of it.
I just purchased a MAC CPU, and i need to buy a monitor. I will be using it to do grapics.
I would like it to be:
1. Under $400
2. Over 19''
3. High Resolution
Please help me pick a monitor for my needs. I am looking the get the absolute best monitor for my money. Thanks in Advance
