Without doubt, the BEST monitor you can buy.
Got 3 on this desk at the moment and another undergoing repairs and another being used for spares.
Very large, VERY heavy, but superb in every way.
Using a 2900XT at the moment and running 2 of them at 2048x1536 and the last isn't running at the moment because the smoke escaped from my laptop that it normally connects to.
Nowhere really sells them anymore. Get in touch with any local design or art centers see if they have any they are planning to dispose of and offer to give them a few quid for them. Other than that - fleabay
If you're planning on getting one - check the amount of weight your desk can handle. I reinforced mine with steel brackets and rods.
