i just tried this, can someone tell me if I did it right/it works? I don't have a Touch to test it on, and I'm not that good with PS.

The negatives are not necessarily the RESULT of the viewing angle, but of bad gamma which is exacerbated by the viewing angle. Download my test images and see for yourself what can be done with a simple gamma adjustment. In my case, I tweaked the images, but the same thing can be done by tweaking the screen (except that Apple has to do it...).

Here you go, in varying degrees of correction:
Original
Heavier Correction
Lighter Correction
Load into iPod touch and compare to computer screen. See???
Bob
That did the trick for that particular image. The lake shadow reflection has a negative effect in the original on my touch, while the corrected one looks the same as the original on my MBP's LCD.
Sweet, I just took a real guess at adjusting the black colours!
This thread needs sticking NOW. I think we can safely say the "Bad screen" issue is now officially fixable.

Please excuse me not being a native speaker and I try to write what sounds most like it. lol
I was thinking about your method in the beginning except I don't know how to do it and I only have MS paint on the computer I now have access to.
I doubt if Apple is able to find out about the identities of the malfunctioning units or is going to adopt your solution because they had not issued a single notice either to the reviewers or its customers.
And yes congratulations on calling me a punk because I am not.
I have a much higher moral standard than that of a punk.
I now have a conclusion on Apple's options adopting your fix.
Apple will NOT be able to do this because there are variations among the malfunctioning units; unless they release a adjustable software repair.
Sorry, but I thought you were being sarcastic to me, and that's a "punky" thing to do. There are not variations among malfunctioning units. It's ALL SUBJECTIVE. Send me any image from any 'malfunctioning' unit and, without changing the settings, send you back one that you would think is perfect. No kidding.
Bob
I have a strong feeling if Apple will correct this issue in firmware it will be corrected this week. The new iPhone firmware should be out by the end of the week, and most likely Apple will push touch firmware out as well.
If the issue will not be corrected in firmware, the pre-order online shipments will have corrected screens and no firmware changes.
I'm crossing my fingers I'm right, because I want to have a solution to this problem shortly. I don't want this to be another random shutdown issue (like the MacBook).

I am not sure but perhaps they are subjective but there are some reports from the people who returned their units and got a replacement of which screen shows better images when playing the same video. It may well be subjective opinion like what you said. But what if they're telling the truth?
Actually if the video card is crap, the best display made will look bad. The display is the result of hardware/software design.
Post a link to a very short Quicktime vid, and I will alter it, telling you exactly what I did. Then we can compare.
Bob
I would rather test with one of the movies I have encoded and watched on the touch repeatedly. I'll consider just registering quicktime pro for this purpose.
Bob, Please edit your post in the beginning of the thread and add these photos. This is quite an amazing feat you have accomplished!!!
STICKY!
Bob,
This was one of the test videos someone mentioned (they said it was the last 30 seconds or so where you can really tell). Please edit it if you can and repost.

What the ****?
Photoshop has nothing to do with this. I've been photoshopping for years, and all it is is an image editing program. I can take a bad screenshot of an iPod touch screen and make it look like it has no problems. But that's Photoshop. What the hell does that have to do with your claim? You think simply because you can Photoshop the images perfect, like any person can, that the problem is a video driver software issue? WTF
You don't know what you're talking about.
If it were a video driver or software issue, it would make no sense that all the iPod touch's are shipped with the same software/drivers, but different units have different screen qualities.
There is nothing amazing about me being able to photoshop this:
into this:
Sorry to be a detractor... but all this does is make images/videos completely washed out. What you're seeing is in no way an accurate representation of what you *should* be seeing.
Haha, you're an idiot. I bet you don't even have a Touch.
It's about displaying it right. I'm not even going to bother arguing with you, but the whole Photoshop thing simply proves the screen problem isn't hardware.

Actually he does. Yes we know photoshop is an image editor program but the significance of this is, essentially the iPod itself can adjust all videos and images to the proper contrast (provided the firmware is updated)
I'm not sure if I know what I'm talking about here, but I think both of the "parties" may be correct on this one.
Bob, I completely see your method, it makes sense, and it works. Bravo. And this fix I also believe could be implemented in a firmware update. I also have not seen a post in which someone returns their iPod for a better one. And the percentage of repeated duds seems inordinately large for a small segment of the manufactured units.
However, I think the root of the issue actually does lie in the reduced quality of the screen. If I'm correct, lower quality screens have a narrower range of contrast and actual color that can be correctly displayed. So, for the purposes of my argument, let's say the iPod touch has a lower quality screen than the iPhone does. It is also well-known by now that the touch shares an almost identical firmware with the iPhone (see the various posts about the string "iPhone" failing to be replaced on the touch). Doesn't that mean that the touch would also theoretically share the same video driver code?
Aah i guess I've been verbose enough, what I'm trying to say is I think the touch's screen problems stem from a lower quality screen/less contrast range, and apple failing to account for that in its firmware. Pleases all?

********.
All iPod touch's are shipped with the same software and drivers.
Yet why do they all have different screen qualities?
Just because I can photoshop a negative picture like this:
into this:
Doesn't prove squat, especially that the iPod touch's problem is "software".
Right, but that doesn't necessarily mean it isn't a hardware problem either.
And since each iPod touch has different screen qualities, a firmware update would effect each iPod differently. No?
Also, software doesn't explain as to why some iPod's just look horrible at an angle, some look perfect at every angle, and some look horrible and negative at all viewing angles.
The iPod touch's software sometimes identifies itself as an iPhone. It's probably shipped with the same "video drivers" as the iPhone. Why doesn't it display it as such?
Guys, the whole point is the correct display values are relative to the device. Your PC is doing gamma correction and whatnot to everything you're seeing here too, you just don't know it. the actual modification of the media that bob did was to simulate what would happen when they fix the firmware.
