Dell 2408WFP Now Available

Ok, here is a new movie to view. Just to be sure I'm not seeing things, I checked it out on my PC CRT, family TV, and iPod Touch. The green is not present in these devices on this next photo. Please have a look and tell me this scene is not all green ... except a few places on the face which are pink, looks really weird:

I do see those images greenish. The one you posted last has the worst green. Only noticed this though when comparing browser window between 19" TN monitor and 2408WFP.

TheBlackHole and ReelMcCoy, did you check those images in another monitor as well and still didn't notice any green? At least for me it was initially hard to notice without comparison, but once seen side by side the greenish tint was easily visible.

Can anyone post any images of the supposed banding issue on the 2408WFP please? Also any video clips of the "DLP type rainbow effect" would be handy to see :)

In the 15 minutes I had with mine, I noticed no banding on the testing website mentioned above. I did however notice the rainbow effect, but as described earlier in the topic, it isn't a function of the monitor but a function of your eyes if they are moved from light back to a dark area of screen quickly.
 
To Overspeed:
For the green tint problem, try to set the monitor to sRGB preset and change brightness to 30 and contrast to 45. With these settings I have a good compromise (it's just a 'little washed' out compared to wide gamut presets but not so far from standard colors). Let me know if it work good for you. Bye!

It's funny, I already tried those exact settings. All it seemed to do was reduce the saturation, but it didnt correct the colors in any way. What should be blue, was still green, just a little less saturated. I fear I will not be able to keep this panel. It's a shame because other than the color issue, I think it's the best out there. No dead pixels, minimal backlight bleed, abundance of inputs, bright and clear, what a shame.
 
Well I was so impressed by the specs and other people's opinions that I decided to buy one as my first LCD. I've been a CRT die hard until now.

In many ways it is quite impressive, but, after setting up the screen as well as possible with the nvidia display optimisation wizzard I tested the screen with Passmark's Monitor test V3. I was very dissapointed to find what I would class as serious banding issues.

Has anyone else with this monitor got similar banding issues on gradient tests?

I can't decide whether to try to get a refund, or RMA hoping that a different one won't have these banding problems. If this is a common issue with these then I'll just go for a refund as I can't live with those bands, especially in an expensive monitor which sells itself on the high colour gamut!
 
I don't think a "CRT die hard" will be content with any TFT <1000 EUR (maybe even 1500) for the near future.
Not even I am, and I am coming from an older PVA-Panel that seems to have much better properties than current ones (213T).

It's pretty much the SAME problem that I have. Visible bandings and pink/red predominance on some greyscale bands. After several tests I can say that the monitor show some bandings but it's VERY acceptable... the problem is mainly the graphic adapter (shitty nVidia on the 2D side). Why I'm saying that? Because I've connected the monitor both to a Matrox Parhelia and an nVidia 6600 GT and the difference in bandings is astonishing! On the Parhelia the monitor show very very light bandings, no pink predominance on greyscale and the gradients are overall smooth. With the nVidia the gradients are visible, pink predominance on greyscale and all the other flaws already mentioned before. Probably the weak point of the nVidia board (2D) is enhanced in this monitor. Changing the monitor will not resolve for sure your problem! Regarding ATi graphic adapter.... is way better than nVidia (tested on this monitor too) but visible inferior to Matrox... so if you want the best colors/fidelity/reproduction you need to use this monitor in conjunction with a Matrox graphic board. If you want a good compromise go for ATi and if you want pure power on the 3d side go for nVidia (but at the cost of the 2d quality)

After in-depth testing IMHO the problems of this monitor are:
- More steps in Sharpening settings (50 is too high and 25 is too low)
- Color uniformity (red colorshift on 100% white background on the right... visible in browsing internet or wordprocessing... where a white background is quite common)
- Color settings: sRGB is under-saturated and other profiles are oversaturated.... a 'middle' settings would be perfect for all environment (exluding photo-retouch where a wide gamut is better)
- Backlight bleed on the monitor corners
- DLP effect where brightness/contrast are under a certain level (but to me this is less important)

Assuming the monitor is connected via DVI there is no rubbish 2D part on the nvidia cards since the signal is digital. VGA(analog) is another story since the quality depends on the DAC and filtering which can vary even between batches of the same card!

The banding is the monitors fault or your input signal isnt 32-bit.
 
That's not fully right. Sure from DVI and VGA there's a difference since in VGA the original (digital) signal is converted to analog and then re-digitalized back by the monitor electronics where in DVI the digital is "passed through" so no conversion is applied (and this means better quality). The nVidia TMDS transmitter is known to be really poor and some boards have also a Silicon Image TMDS (often the cards with 2 DVI output... where 1 DVI use the internal poor TMDS and the other use the external TMDS). The nVidia specs doesn't say much about TMDS quality and nVidia itself in his reference board uses its poor TMDS. With single link DVI (1 DVI port with 1 TMDS) the max resolution is 1920x1440 at 60Hz (165MHz bandwidth). You see that if the TMDS works at a lower bandwith (like nVidia has) the quality at max-res supported could be 'lower' (a dual-link DVI could be a solution). This explain why some monitors lose the signal or doesn't detect it at all if the TMDS is poor.

What's change is also how the 2d graphic is internally made by the chip (not only how is outputted to a cable) and here is where Matrox made the difference (just see that on the Parhelia you'll get 10bit per channel output).

Anyway, I've made the test with the same computer with the same monitor with the same resolution/settings (1920x1200@60Hz - 32bit on DVI connection of course!). The only difference was the graphic adapter (nVidia, Matrox and ATi) and here is where the differences comes to light (Matrox is way better than ATi and nVidia... with nVidia the worst).

The Matrox card is not mine (I have the nVidia!) so I'm not by Matrox side... but I have see the differences with my eyes!

Things have changed, all this is back in the day.
The 8800GTX for example handles all the display h/w externally using the NVIO chip.
NVIO is 400MHz DUAL DUAL-LINK, it is still 8-bit however there is no advantage with the matrox since your output device is still 8-bit.
 
Dunno which nvidia card Tigger01 have, but I own a 6600 GT and I have the same banding issue. I don't have an 8xxx series so I cannot compare the 2D performances of the new nVidia graphic adapters. I tested my 6600 GT with an ATi x700 (if I remember correctly) and a Matrox PCIe and the differences are summarized in my previous post.

The 10bit per channel are useful really for avoid banding problems (or limiting the problem anyway) in a similar way as the 8bit, 10bit or 12+bit LUT in a monitor.

A bad transceiver causes loss of signal and certain kinds of artifacts, but no banding or other subtle image degradation.
Also, both of the ports of my 8800GTS manage to pass a 1080p60 signal over a cheapo 15m cable (27 EUR) so they can't be that bad.
Either way, it has nothing to do with banding.
 
Ooooohh!

I didn't expect that!

I've just updated the Nvidia drivers to the latest and it has made a huge difference to the banding issues I was seeing. I can still see some fine bands, but the problem is so much better now.

I've got an Nvidia 6800GS by the way, with the display connected via DVI, and set to 1920x1200 at 32bit colour. I was using forceware 93.71 (yeah about 2 years old, I know!) and have just updated to 169.21.

This is what my gradients look like now, showing just the left half of the screen as the bands are more obvious at the dark end. I've deliberately got the Dell logo in the picture so you can see exactly how much of the screen you are looking at.

Grey close up. You are seeing about 80mm of actual display width here (sorry about the map measuring ruler). The slight light and dark splodge in the middle is just a reflection.
2321100436_e3d134b323_b_d.jpg



So how do these images compare with people's expectations of colour gradients on LCD displays? Although I can still clearly see bands in the gradient, about 2mm wide, I think I might be able to live with these, unless anyone knows of another similar sized display which shows no banding at all?

Useful only if the output device can handle it, yes it will make a difference if you own an Eizo/NEC with 12-bit LUT, the DELL is 8-bit all the way.
 
Tigger01, that's more like what I see with the 2408 hooked up to two systems with 8800GTXs with the latest drivers.

Hmm... so you claim that your SRGB colors look good and only bit washed out compared to wide gamut colors?

I am asking this because in my 2408WFP SRGB looks really horrible and washed out no matter what brightness & contrast settings I use. Like as if there was gray between my eyes and screen ruining the colors.

And that is not only compared to vivid wide gamut colors but also visible when using another monitor as reference.

I am wondering if mine is somehow defective or do everyone else have this problem also? It's rather annoying when SRGB is completely unusable and wide gamut colors in turn are shown all wrong (colors look a lot brighter and have different tones than they should have).
 
There's a workaround... using wide gamut with correct colors but this affects only photoshop and websurfing with FireFox 3.
If you change the windows default colorspace from sRGB to AdobeRGB 1998 and then enable the color management in FireFox 3 then the colors are corrects (with the monitor in Custom RGB with all the 3 channels set to 100). This fully resolve the problems for those applications that use color management. In Windows the desktop will still be oversaturated due to the fact that the colors are still converted to sRGB prior to go out to the display. Probably in Vista this problem can be resolved too but I haven't tested since I don't like Vista very much.

This monitor has a Sharpness setting :confused:? I've never seen this setting before on any monitor I've used when connected through DVI. I was under the assumption that digital connections (DVI) didn't need any sharpening, but maybe I'm mistaken.

Yes it has. I have seen DVI sharpness also in Samsung monitors (970P/971P), but Samsung made the control work correctly with enough steps and also with correct default value. Dell 2407WFP-HC also has a sharpness adjustment but it only works in scaled resolutions, in default resolution it does not work and sharpness is correct without any problems. Maybe the 2408WFP was going to be the same, but Dell made a mistake in the firmware and enabled it in all modes?
 
Are the 2408 slanted (right side lower) on the stand like many of the 2405's and 2407's were?

Click to expand...
The 2408 when mounted to it's own stand can be rotated 90 degrees (or more?) and it sort of snaps into the horizontal or vertical position. The 2408 I had (it was returned to Dell today) wasn't slanted, but even if it were you could probably fix it by rotating the screen a little bit.
 
I know they can be rotated but when in the maximum horizontal position, is the display level?
The sagging problem used to plague the 2405's and some 2407's.
 
I just wanted to update everyone that I did return my 2408 and did not get a replacement. This will be a great monitor once dell works the kinks out of the display.
 
Anyone here upgrade from a 2405? I have one still and I'm wondering how this will compare. The input lag is awful on the 2405, as well as the ghosting. Is this much of an improvement? I really hope so, its upgrade season.

 
Hey everyone, first post here.
I ordered a 2408WFP the day they came out and received it on Feb. 18th. It is really a crisp monitor and with the settngs set to custom RGB and each setting at 75 it looks great except one issue... The over saturated red that makes everything red look almost neon pinkish-orange, very cartoon like. I called Dell and they sent a second one out, same issue. Today they sent a 3rd one and again it has the same issue. It really is too bad because they are a nice monitor other then that. I am going to do photo editing so color is pretty critcal to be at least near what I see on screen. I will be returning this for a refund and am considering a NEC in the 24 or 26 inch IPS monitors but I would be open to other suggestions.
 
Wow, sounds like you guys are getting some decent service in the states - here in New Zealand it's horrible. I've just shot this email to Dell in the hope something is done:

Because of Dells slow response, I have already initiated a replacement via phone on Friday. I was given the reference number x.

Half an hour after my phone-initiated replacement request, I was phoned to be told that there would be an unknown delay in me getting that replacement and I would be told how long that delay would be on Monday (today). I have not yet received this phone call.

I would appreciate this matter being escalated as all this buying experience has been is failure after failure.
Click to expand...

So far, Dell has failed on the following points:
  1. Sending me an obviously damaged monitor (had the monitor been turned on at the factory for basic QA this would have shown up)
  2. Not replying to my replacement request via the web until 48 hours later
  3. Not bothering to return my call to inform me how long the replacement monitor will be after I phoned in my request (as at that stage I hadn't recieved a response to my web request)
  4. Honouring their next business day warranty - apparently it means they'll reply to an email within 24 hours, not have a replacement monitor on its way to you :rolleyes: (that'll take about a month here in New Zealand by the looks of it)
Yeah, not happy :mad:.
 
I have tested the 2408WFP with an ATI HD2600Pro video card, I earlier had an Nvidia 8600GTS.

I have noticed these two big differences:

1. With the "Eizo test" color gradient banding is almost gone, it's much better than with the NVidia.

2. The ATI Catalyst Control Center has a DVI-panel adjustment called Avivo Color that has adjustments for desktop saturation and hue. Those adjustments allows you to reduce wide gamut monitor's oversaturation (you can adjust colors to zero i.e. black and white picture) and also correct greenish blue to more correct blue tint. (This is a different adjustment than Avivo Video that only adjusts video content.)
 
hey i have a 2407wfp. I am looking at getting another. But they only sell the 2408wfp. From what i read on like page 6 the 2407wfp and the 2408wfp look the exact same, cosmetically. Meaning If i have dual displays side by side, they will look the same right?

I just want to clarify this. The 2408 looks the same on dells website.

That is the same issue I had, except I had read many others had the issue so I returned it. I also had severe color distortion at the right and left edges than many others also reported. It is easy to see that issue with this test:

You may want to read about the issues many people are having with this display before you purchase. The 102% gamut seems to be a technical challenge they have not yet solved. The specs are different.
 
what a joke, things go from bad to worse... why are there still pending issues.
 
i want to ask a question for you all. i have an old samsung syncmaster 204b 20.1" 1600x1200 lcd monitor, would you get (if it was you) a monitor like this 2408wfp dell 1900x1200 lcd, it got 1200 lines like my monitor, would you any?

300 pixels horizontal obviously won't make that much difference to you but if you like the widescreen for movies, the various inputs, enhanced color or design then I might suggest it.
 
thanks overspeed. and how about the image quality, my lcd is tn, and dell is pva i think?
