The link below provides the issues that 2407wfp customers are experiencing with A02:
http://forums.us.dell.com/supportforums/board/message?board.id=dim_monitor&message.id=60244&view=by_date_ascending&page=1

So, Dell does not mention if a fix is under way.
This is unfortunate since I am very interested by this monitor.

This is my interpretation of the 2407WFP A02 targeted users
1) Colors picky peoples (such as photographer, Web site designer) should look elsewhere since of the vertical banding
2) Multimedia oriented peoples should also look elsewhere since the component is currently useless
3) ATI owners that are 1600*1200 oriented (!) should also look elsewhere
4) FPS gamers with high end video cards should be happy (Input Lag and Responds time are low)
5) Programmers should be happy
6) UPS/FedEx shareholders should be happy since of the high number of returns...

Chris,
 
1. Banding still present in A02
Did you or engineers have a look at vertical banding? if you try some new games you will see alot of things that especially use light sources on objects or things like smoke particles are extremely affected by this banding... it really does look bad, just using desktop for webbrowsing and normal use is fine and looks good. but games where light and shades are used looks very bad, can you look into this please?
 
4. Incorrectly displays 1080i over component giving an usable image
Using 720p over component still gives a bad picture sort of like a dark slightly blurry fuzzy picture... its not clear enough and the image colour or contrast needs to be adjusted. please also look into this, especially noticeable on xbox360, the image is unusable.
 
Composite picture is still also unusable image as there is all blurriness and a weird pattern line effect you will see this easy if you plug in a dvd player via composite.
 
Also another issue is my LCD drops/leans more to the right side.... i have received 3 of these monitors and all 3 have the exact same problem where about 10mm lean to one side and is noticeable...if you try forcing the LCD the other way n bending it it still eventually sits back to the right side, this is especially noticeable when you tilt the LCD into portrait mode..
 
All these faults above i get identical in all 3 LCD's i have.... hope revision A03 will be released to fix all issues, maybe the scaling chip needs to be replaced in all the units to fix alot of input issues?

Banding is fixed in desktop mode.




Banding is fixed on 2007 not on 2407 do you use a 2407 or is Dell wise enough not to give its employees defective monitors?

Please revise it to tell the truth. Banding is not fixed.

I also have banding issues in desktop mode, so there’s no way that can be considered fixed its bad enough with default color settings that I even noticed it on the taskbar :/

But I also have noticed another problem that I have not seen mentioned in a while. when in S-video or Composite mode the source is stretched horizontally this is especially noticeable when circles appear on screen

Add another vote for banding still present, although I can't see it doing much good. There's been complaints of banding still being there since the A02 first came out but Dell still wants to claim it doesn't exist. Banding is still present in vertical gradients in Desktop mode on the A02 model using DVI. It's noticable in all aspects of using the monitor -- websites, the windows UI, pictures, photoshop, everywhere. Sure it's nowhere near as noticable through VGA but I bought a monitor with DVI input for a very good reason... to use DVI!

yeh i am also getting a stretched picture through composite.... if you set it to 1:1 or 4:3 i think the picture looks ok (apart from quality) but as soon as you put it to fill it stretches to a point where it doesn't look right... even with a widescreen enhanced DVD it still look stretched...
 
Xamayon aside from this do you get a funny blurry and pattern like picture through composite?? or are you happy with the picture quality..

For me its not just in Fill mode that it is distorted, in 1:1 and 4:3 it displays slightly wider than it should be, throwing off the whole picture. but yeah Fill is amazingly bad :)

as for blurry, and pattern through composite, yeah It is pretty blurry through composite, and if you change the sharpness, it creates a weird pattern of moving brightness on certain colors

there is a 'checkerboard' pattern that appears on a much wider scale in S-Video mode but only on a specific brighness of colors it is somewhat disturbing, but the colors arent the most common in the world. the Blue GTA3 Arrow's color, and a shade of red in the Sunset of the opening movie of FFX are two examples where it really stands out. I managed to mostly eliminate this pattern by lowering the default sharpness, not an ideal solution, but it works for me.

All,

I have asked Product Group to read through your responses on this thread.

We recommend 720p over component for the best image quality. 1080i deinterlacing is enabled but you may experience artifacts in some images.

5. Video tearing on 720p over both component/DVI when in 1:1 mode
We are investigating this issue.




4. 720p is hardly an improvement over 1080i via component. Only difference is that the image doesnt shake. It is still blurry, washed out, dark, and over saturated. What I want to know from the product group, is why did the component input work SO much better on the 2405fpw? How is it that you broke something on the new model that worked fine with its predecessor? That is unacceptable.

5. It is important to note that video tearing also exists with the VGA input when stretching an image by maintaing the aspect ratio. It goes away temporarily when you restart the monitor, but comes back often. It needs to be fixed

Regarding banding: yes, it has been fixed... ON HORIZONTAL GRADIENTS! Did dell forget that there are vertical gradients as well? Vertical banding is still very bad, and needs to be fixed.

ChrisM,

Does this thread mean there might be a new revision? A03?

I'd like to buy one of these monitors, but will wait till I hear back from you.

Thanks.

Totally agree with this statement. Vertical banding is NOT fixed. Very noticeable in everyday use with web pages, etc.

I posted this in another thread but realized this one is the happeneing one so I'm reposting it here.

------------------------------------------

hmmmmm. This subject has been beaten to death and everyone still talks about it. I for one kept believing that this issue of banding was so minor that it didnt matter. So I ordered a 2407. just got it 2 days ago. I love having a huge monitor. Its really great.

 
But that gradient issue is still very there. you can even notice it in games and websites. Its not just when you do finiky work in photoshop.  True it is mostly a vertical gradient but its more then just that. horizontal gradients mixed with the verticals turn out rather strange like a baddly compressed jpeg. My worry isnt so much the gradient as why its there and why it "disappears" when you put a complex photo on. I dont believe there is just a "simple fix"
 
Let me explain: the dell 2407 (from the many hours of research of done) is a 8-bit display powered by 6-bit electronics that dither up to 8 bit. (this means that the statment that it has 16.7 million colours is a very sneaky statment and a partial lie. It displays them sure. but it takes 16.2 million colours and guesses the inbetween stuff.) I don't know if I'm correct in saying this but I think the gradients is the one part where dell can't hide the fact their electronics are a bit subpar. Their dithering "electronics" get confused with gradients and cant fake the inbetween colours.
 
Now the part that really worries me. You dont notice the gradients in most fairly complex images. This is because the 6 to 8 bit dithering works quite well in hiding the fact that its not displaying you the image as well as it should. but its not really hiding it. its compressing and then showing you an image that actually looks a bit compressed.
 
If you just play games and a bit of web browsing then this monitor is great "for the money. it has a fast response time(because it doesnt display as many colours). Although I tried it with Prey and half-life 2 and found it not perfect with gradients. other then that its a great gaming monitor. the size is perfect for awesome widescreen gaming.
 
If you want this for HD quality movies or for photowork your looking at something that might not be good enough. You will notice gradients in movies unless a lot is going on(an example would be the WMV logo 1080i sample movie). and even then you are not getting as good colour as a true 8 bit monitor.
 
I love gaming but I also need this to be fairly good for photowork and I really dont think it is good enough. dell cut back on the electronics and it really shows. Im going to try one replacement and see if its a bit better but I doubt it will be judging by the tons of issues Ive read online.
 
Sorry Dell but you definately made a mistake with this one.

edit: apparently chris says it is "true 8-bit." I've read so many things otherwise. One was from someone who said that they talked to someone who worked on the european model and was told it was 6 bit with ditehring up to 8 bit. I don't really know if thats true or not. I do know what I see though. and what I see feels like 6-bit. Am I wrong? maybe. butthen maybe dell should make true 8 -bit electronics that look 8-bit. 

If this 8- bit is true then I have another question:

can I hold onto this monitor until revision A03 and then exchange it? I want to know this because then I might considere hanging onto it with the hope I will get a better version. But if I will be forced to stick with this one then I think I shall return it.

on last thing - Ive had 2 other dell monitors and they were both quite good. Ive always loved dell monitors. Thats why I'm really hoping this thing gets a bit of an upgrade. Ill pay an extra 100 bucks for a bit better electronics.

sorry for so much writting. I relooked at chris' message that the "PANEL" is true 8 bit. The past part of my message agreed with that anyways. it maybe a 16.7 million 8 bit panel but the electronics powering it can be 6 bit and then dither it up to 8 bit. Id like him to clarify that everything about this monitor is 8 bit, not just the panel.

Banding is definitely not fixed, even in Desktop mode. I can clearly see banding in most of my wallpapers! It really is still quite bad. The quality of component in from the Xbox 360 also leaves a lot to be desired, and games generally look disappointing.

Also curious if a Rev A03 comes out, will the A02 folks be able to to an exchange as the A02 panels are STILL defective.

This is what I've experienced also.
