Just received my 2407 A01- No problems with it

Question

And I can't find anything wrong with it.

DVI mode:

I did the gradlin test and could barely see any banding. Zero dead pixels. Games look perfect on it.

Haven't tested a DVD yet but I tried some divx movies and they were fine.

If DVD's are fine I'm not going to bother getting an exchange for an A02 and risk getting dead pixels.

The picture quality is way better than my 17" Sony and I consider the Sony a good monitor still.

Regards

Happy Customer

Have you checked on the panel's backlighting ?

Does yours have a brigter display on the Left side than on the right ? The RHS has a slightly blue tint and darker too .

Appreciate if you could help us check on this.

Goldy67blue · Answer

I didn't notice that at first. Yes it is a little blue on the right. Is this a returnable fault? I'm not particularly worried since I use this monitor for CAD and mostly have a black background.

Sounds like a manufacturing problem or maybe not .

Goldy67blue, please check these images. Japanese found banding problem with their 2407 A01-DVI mode . As for this problem, how to appear is different in horizontal and vertical gradation.

Goldy67blue · Answer

Holy, horizontal banding is actually quite bad and scrolling makes it twice as bad. Thanks for those pics. Guess I'll pm chrisM right now :(

Yea, I have an A01 as well and I do see some horizontal banding, but i'm not sure if it would justify sending it back and possibly getting a pixelated A02. Decisions decisions.

Whitey : Do you have the backlighting problem on your A01 ? Compare the brightness from left to right . Is it uniformed ? or darker on the right ....

Gymrat76 · Answer

How sure are you guys that the A02 doesn't exhibit the same horizontal banding observed in the A01? Don't wanna send back my A01 (which is almost perfect IMHO) for an A02 that has the same problems but with scratches and dead pixels :(

WHOAguitarninja · Answer

In the above picture I see NO banding in horizontal gradients. None. At all. There is banding in vertical gradients however.

I have my brightness at 20 and it seems fairly uniform. Of course I have worked for 10 hours today so.... maybe my eyes arent working perfectly.

On one hand I really do like to have the most updated version, but if they're going to just send me a relabeled A01 with a A02 sticker then I'm not sure it's worth it. Especially knowing that someone in a diff factory was manhandeling it and possible scratching it.

If it was right off the assembly line so to speak, then maybe.

Plus I'm just not sure that A02 is much of a revision over A01. Hmmm, I have to decide within the next 10 days or so before my 21 day is up.

Revision A02 Mexico - DVI-I Banding on Vertical gradient. - VGA No Banding at all (but fuzzy text)

Gpinner · Answer

I was working in Photoshop with my new 2407WFP A02 Mexico and noticed a new banding problem on Vertical AND HORIZONTAL gradients!

ISSUE : The banding is much MORE visible when working in 16bit channel than when working in 8bit channel mode,

Test it for yourself:
- Create 2 new images.
- One using 8bit channels (in photoshop go to Image > Mode > 8 bit)
- One 16bit channels (in photoshop go to Image > Mode > 16 bit)
- Create vertical gradients in both images (compare)
- Create horizontal gradients in both images (compare)

The result is terrible in 16bit.
Theoretically the 16bit image should display much less banding! But because the issue is monitor related, this theory doesn't apply here. Well, it kinda does, but in reverse! Therefore, for any sort of color correction work, this monitor is useless. It will display artifacts which will prevent you to accurately assess your images/photos.

This is such a disapointment because other than this major issue, this monitor is absolutely fantastic. Dell has already released two revisions, little by little they are getting closer to have it completely fix. Will they release A03? Pressure is on!

Well the panel is 8 bit only isn't it so 16-bit should look the same as 8-bit...unless the firmware screws up dealing with 16-bit colours which I think it what you're getting at.   Who here thinks that 2007s and 2407s were fixed by different teams?   I did the above test on my 2007WFP and the two look exactly the same. Now before anyone jumps to conclusions, I'm not saying it doesn't happen on a 2407 or what not, but these both have Faroudja problems, but fixed to different extents, which is why I'm thinking this 2 teams thing.   Although it seems clear that the place doing the actual flashing is the same thing for both monitors cos of these A02 labelled but seemingly unflashed ones are popping up everywhere. :smileyindifferent:

Gpinner · Answer

That's right. I was talking about how the firmware is unproperly dealing with 16bit images. You proved my point by mentioning that the 2007 doesn't display the same artifacts. ;)

BTW, all my tests are done using
- DVI
- No gamme/Color Correction
- Desktop mode (no Faroudja)

You proved my point by mentioning that the 2007 doesn't display the same artifacts. ;) What's the point? (really honest question :smileytongue:, I don't see it :smileysad:)
