I just received, last night, a 2407 made in Mexico and A02 on the firmware. I do not see any banding on either the VGA or DVI inputs in any of the three modes. Having said that you may care to have me run a specific test to see if perhaps I am not looking at this correctly.
You should also know that I am using this for PSCS2 (Photoshop) work and really do not have an interest in 1600 x 1200 resolution nor a 1080i input or (you forgot) HDCP compliance. The only game I play on my computer is solitaire.
So my only real concerns are gradient bending and banding. Neither of which seem to be displayed to me here.....but I would like to apply your methods of detection to ensure I have covered the gamut before I proclaim I got lucky and snagged a decent one.
My primary complaint is an uneven brightness from left to right....but that seems inherent in almost all LCD's to some degree.
Not only is this monitor experiencing major design and display problem it is poorly built compared to the 2405. The stand will not stand. The monitor leans because it won't lock in a horizontal position. The back of the monitor is all silver and not black like the 2504. The front view has a silver outer lining that causes an eye distraction when viewing. This monitor is inferior in everything compared to the 2405 in my opinion.
Just to be sure: Using checkmon color gradients, you ARE SUPPOSED to see banding in ALL strips except the ones in the very BOTTOM strip of each spectrum. The other strips are step-wedges of various density steps. Did you see banding in the bottom strips? If not, you're OK. Caveat - checkmon only checks for vertical banding. A better alternative is to create radial gradients in PS which will tell you of banding at all angles.

Shilesh--
I think your summary is correct. I see banding on the "color spectrum" test in CheckeMON--this screen is basically equivalent to radial gradients. When I bring that screen up (using DVI), I get regular banding up and down my screen (but no banding using VGA input).
Also, if you look at the thread referenced in my posting above, there is a black and white radial gradient among the images. On my screen it looks almost like radial banding with DVI (and smooth with VGA).
You can get an idea of the improvements made on the A02 by switching from Desktop mode into the other 2 modes. Additionally, you might want to take a look at the graphic in VGA input--no banding whatsoever, regardless of the mode (doing this comparison also makes the banding on Desktop in DVI that much more apparent when switching between VGA and DVI in that mode).
Randy--I don't think there's a problem with the LCD, because the images seem to work with the VGA input, rather it appears that the problem's with the DVI in the 2407.
Is there anyone out there with a China 2407 A02 who is experiencing banding on DVI?
Well that green / purple thing did it for me. I brought it up on my 4 year old 21 Dell 1130 monitor and it was silky smooth. I just brought it up at work on a really old Dell 19" crt and it looks nice and even and smooth as glass.
It looks like absolute junk on the brand new (Wednesday arrival) 2407 from Mexico Rev A02. I only checked in DVI mode because that is how I intend to use the monitor. The best rendition was in desktop mode, but still nowhere near as nice as the CRT's.
So, is this just the way things are with LCD's? or is this a 2407 specific issue? ChrisM....any guidance for us?
I just ordered one yesterday, and it shows it shipped today (I'm sure that means UPS will be picking it up from Dell on Monday). I am fully aware of what problems I
may encounter, but I am fully confident in Dell as a company that if I do happen to have problems that I notice on a day-to-day basis, that they will correct the problem for me. Wether its the next revision (A03?), or the next model, I'm certain Dell will take care of it for me. I also got the 4 year warranty with it, so I fell OK about my purchase, and think its a good time to buy one seeing how they are on sale from Dell directly currently :-)
