HP Compaq LA2306x Black 23" 5ms Widescreen WLED Backlit LCD Monitor 250 cd/m2 1000:1

Pros: Great LCD Monitor!!! Extremely adjustable from hieght to turning it. There is no glare and it just looks good for using at work.

Cons: The software that comes with it so you can turn the monitor simply does not work under Windows 7.

Other Thoughts: Recomend you do not use the software that comes with it and instead just using the software for your video card to turn the display with the monitor.

Pros: I have a great dual monitor setup of these at work. Not my purchase decision but I'm happy with what I have.
Height is adjustable and it stays where you put it.
Orientation is adjustable.
The base doesn't actually take up desk space because it's curved. The flat space is about 8"x8". The back half of that has a roughly 2" clearance (note I have monitors at full height).
YouTube looks fine but I can't comment on hd video playback because I use them at work.
I am no expert on color but my blacks look black and my whites look white.

Cons: No speakers. Not a flaw but something good to know if you're upgrading from one that does have them.
No left/right swivel but they slide easily

I stare at these for 40+ hours a day, 5 days a week. I think I would've noticed any relevant flaws.

Other Thoughts: My PC uses a DVI to VGA splitter, but the monitors have several inputs and USB ports.
USB ports are on the left back if you're looking at the monitor front. If you dual screen, you won't be able to access the USB ports of your right screen so you might want to have whatever you plug in there be more permanent.
