2407 Rev A02 Does NOT fix Banding! ATTN CHIRS!
Hello Everyone,
I've just received my Rev. A02 monitor and set it up next to my 2405. While horizontal gradient banding is better, it is still present in the vertical and terrible in the brighter half of a 45 angle gradient. This is simply unacceptable.
To top it all off the 2405's stand is FAR superior as it is much higher.
The 2407 is going back and I'm keeping my 2405.

The 2405 is better built, period. I bought the 2407 to replace my 2405 and I was surprise to see an ugly housing, all silver on the back. The stand was clumsy and would not lock in a horizontal position. It kept leaning to one side. The monitor has a silver outer lining that you can see from the front view and takes away from the black bezel. I like the looks of the 2405 a lot better.
If you don’t have to have 6ms response time then this monitor is not for you.
I never could get my 2407 to display for more than 1 second before going to a blank screen. I returned it and got my money back. I will not buy another one just because I was disappointed about the overall build quality (or lack of) of the 2407 compared to the 2405.

Are you in "Desktop" mode? I see absolutely zero banding from all angles on my 2007WFP.781

Just received A02 replacement - same banding problem as A01 has. It's not the same as A00 had but still not acceptable.
Especially if you work with PhotoShop the banding is clearly visible and very annoying.
So what's the solution Chris? If there is a fix what should we do? If not both 2407 going back for a refund.

All,
When testing the monitor in Desktop Mode, all Photoshop "Adobe Gamma" changes must be turned OFF.

Just got an A02 (assembled in Mexico) and the banding is VERY evident. Using that horizontal and vertical RGB and combined gradient image that has been floating around here, it looks totally smooth connected through RGB input, but there is TONS of banding from brightest to darkest in the vertical gradient and some broad wide bands at the darkest 25% of the horizontal gradient.If I rotate image 90 degrees, then same results, the now vetical bands have banding from top to bottom and the now horiz ones have it at the darkest 25% end.I don't know what the story. Maybe some fatal flaw in the DVI input chip or firmware coding for gamma profile for DVI input? Very frustrating, this could be a simply amazing monitor, but banding mars DVI. (and there is also the silly issue of why in the world was this old Faruodja chip used that can't even handle 1080i especialy with the big deal about HDCP?? would anyone have objected to $20,$50 or whatever more when it already costs $800-950? but more concering is the banding, since that part I thought had been fixed before I ordered). Is it time to just end production and release 2408 with proper chipsets? Seems a shame to go 90% the way, using a great panel and all, and then mess it all up in the last few tiny details of electronics and programming.In the vertical gradients I swear I can only see something roughly like 90 distinct shades, not even 7bit performance!781

It seems I'm not alone. I should point out that I didn't PM Chris about this and just had Dell Canada ship me another one figuring that I'd get an A02. Are there verious versions of the A02 Revision? I'm pretty set on keeping the 2405 and sending back the others. By the time I need HDCP I'll probably be upgrading anyways...
I can't see a difference in response time either...
I'm in desktop mode, no Gamma or LUT corrections applied. Even using my spyder doesn't help things (it makes the 2405 gradients smooth as glass).
I may have been one of the first to discover issues with the 2xx7 series when I had 3 2007FP's with horrible banding before giving up and getting the 2405.

Chris, it's not only in PhotoShop. Gradient test images and gradlin app have vertical banding plus 45 angle gradient is also horrible.

slava55,
Then we can issue another exchange or you can return it for refund.

Hi, yes, turning off Adobe Gamma does help a good deal, now the horizontal banding is 100% absolutely gone even into the darkest shadows. However, while the vertical banding was also a bit reduced it is still clearly there in red and green (blue is still there, but now very hard to spot unless much closer than normal viewing distance).
So, yes, thanks, that fixed the remaining horizontal banding and helped with vertical, but, I have to say vertical banding is definitely still there, certainly muted now, but all the same I don't have to look hard to spot it either still. So there is still some sort of issue. It is weird that the bands are many pixel thick, so why it should be able to distimnguish vertical from horiz I'm not sure (i know the dot stripes RGB are aligned vertically, but I would think over a number of lines it would avg out more and not look like this).
