Latest 2407WFP Q&A
1. Banding still present in A02
Banding is fixed in desktop mode. For multimedia, gaming and non-prime modes, we have left the complete set of Faroudja video processing enabled so banding may still be visible in some cases when the color enhancement processing kicks in.
2. Doesn't support 1600x1200
2407WFP supports 1600x1200 in fill mode only. 4:3 aspect ratio is not supported.
3. Doesn't support 1080i over DVI
The DVI connection is designed for PC connectivity. Simliar to the 2405FPW, 1080i is not supported in this mode. We support 1080p over DVI for HDCP usage. Progressive video has better performance over interlaced formats.
4. Incorrectly displays 1080i over component giving an usable image
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.

Chris,1. Banding still present in A02Did 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?Message Edited by AssyrianKing on 07-31-200605:42 PM

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.785

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 screen785

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!785

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..785

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.Message Edited by Xamayon on 07-31-200610:15 PM

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

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.Message Edited by altdelete47 on 08-01-200602:32 AM

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.

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...
