First, as a rule, I hate Dell products.
That said, Ive owned a 2405FPW for several years now, and it was/has been a great investment. I bought it to replace an NEC 18 inch LCD, for use in 2D/3D graphics, video, word processing, web browsing and as a TV, with the occasional game.
The 2405 has reasonably fast response time for an older VA panel, generally good color reproduction (see below) good viewing angles and nice ergonomic features -adjustable hieght, tilt, swivel and rotation. A decent OSC, DVI, D SUB and S Video inputs, plus an onboard card reader and usb ports, all of which Ive used.
The only real downside is the color gamut. Far superior to any TNs of the same era, the blue range is a little limited relative to newer VA panels, and this redution in blue range translated to some difficulties with subtle shades of green. The test I got used to using for green was the bamboo forest scene from crouching tiger hidden dragon. On the dell it gets a little blocky, but its not noticable unless your sitting right up to the monitor. The gamut tools I use (for CorelDraw - I dont use adobe) shows the greens fine, and I dont get uptight about the greens when Im working graphics.
My only other problems are pet peeves.
1)The screen in screen feature allows you to use either the DVI or the DSUB and any of the other inputs, but not both the DVI and D sub. Obviosly you cant do this anyway, but it would have been nice to run systems simultainoiusly.
2)The card reader does not handle the newer high capacity class 6 SDHC cards, even with the last driver updates from dell.
I recently purchased a HannsG 28in monitor to replace this Dell, but Ive been so spoiled by the Dell that I sent the Hanns back and took a considerable loss on a restocking fee.
So is $320 worth it?...Maybe. If its in great shape, yes. If its in poor shape.. not really. There are a lot of newer monitors out with attendant improvments in technology, and prices have droped considerably over the years.
