X-bit Labs took a look at three big ass LCD displays: the 30" Dell 3007WFP, the 27" Samsung SyncMaster 275T and the 30" Samsung SyncMaster 305T.
Here's a short quote from their report:
Today we are going to look at three solutions from Dell and Samsung with 27” and 30” diagonal. 27” monitors may be interesting for people who often watch movies on their PC and who need a large screen with a resolution sufficient for HDTV. 30” models may make a good work monitor for people who process complex design drawings and schematics or have to work with multiple documents at once. So, let’s see how good out today’s testing participants are!
