Band of discoloration on C2D LCD

Hello, I'm having some trouble with my C2D (not santa rosa) lcd screen. I was wondering if anyone has advice or has experienced this?
Early today I noticed that on the right side of my screen there was about an inch of screen that was darker or differently colored than the rest. On white/gray backgrounds it appears somewhat yellow, and on light blue it appears dark blue. It doesn't fade into it, but rather starts abruptly about an inch from the right hand side and continues all the way to the edge.
Anyone seen this before?

Contact AppleCare as most likely it's a hardware issue. You could try resetting PRAM…

Gradient banding in Samsung 20 inch LCD

Now idk where to begin, ok here's the best info i can give
I just assembled a new pc for graphic work/budget gaming 2 days ago:
intel core i3 530 mhz
2 gb ddr3 ram 1333 mhz
xfx nvidia geforce gt 240 1gb ddr5
windows 7 ultimate 32-bit
Samsung Myst Eco B2030 widescreen 20 inch lcd monitor
Now when i opened an old psd which contained some brushing and gradients, i could see bands in the gradients, even the wallpaper i put had bands on it. I even noticed that everything on my lcd looks hellish sharp, and when i force my head really close, i can see small square pixels all over the l cd. Is it due to the analogue output(VGA)?, should i switch to DVI?
I use 1600x900 res (native) at 32 bit
Then to test whether all gradients look the same, i opened a new ps document and made a black to white gradient, but it was smooth, there were no bands in there. But when i made a simple white box, applied full gaussian blur, and zoomed in around 2000% i could see the gradual bands again though not as bad as in the colored psd. It seems the problem only happens when i give a glow, or blurs. Then i played Splinter Cell Conviction (everything Maxed out) and again i could see gradient bands forming up in dark places, like when i die and a small cutscene is played, i could see gradient bands on the 4 corners. What could be the problem, is it the card? the lcd? i am new to lcd monitors so i dont know how to calibrate or whatever.
Please check if anyone else can see the bands on their lcd?

Regarding calibrating your display, it's not strictly necessary, but you did mention "oversaturation" in a post above. It's certainly your call whether you want to make your color-managed applications put out calibrated color.
Re switching to DVI, that's falling out of favor... How are you currently cabled to your monitor? HDMI? VGA? You've mentioned both. DVI would CERTAINLY be better than VGA.
This "Coarse effect" you speak of... Are you talking about jaggy fonts, or what? If so, do you have Font Smoothing enabled?
When I first switched from CRTs to LCDs (in 2004) I marveled that most graphics created by people using CRTs were actually butt ugly, simply because they could not see the actual image content very clearly and tended to overlook things and overcompensate for their own monitors' shortcomings.
On a good LCD using a good interface (DVI or better) you can see every pixel as a discreet element. That's a given.
After my switch from CRT to LCD I had to reset my perceptions - I had thoughts just like yours! After a while you start to realize that what may look oversharp and harsh to you may even still be too subtle for CRT users. For some time there's been a mix of CRTs and LCDs in the world, though honestly lately I've started to ignore the former as they are truly a dying breed (just try to buy a new CRT monitor nowadays). It is not wrong to concentrate solely on making graphics look good on ultra sharp LCD monitors. Don't be too hard on yourself for what you've produced in the past, when you couldn't "see clearly" yet.
That said, I should note that there are some LCDs that are not sharp at all. From time to time people post on this forum that they have trouble seeing the Photoshop UI elements at their fixed small size, and as you're no doubt aware now with your monitor there's really no problem seeing them on a very sharp display.
You could try taking a macro photo of what you're seeing on your display that you don't like. Other than that it's very difficult to communicate about such issues on a forum.

"Bad" colors/banding when going into Edit mode with Canon RAW files

Just got my iLife '06 suite yesterday and ran into something very disturbing: something wrongwith the colors of RAW files once you go into editing mode. In the library view, they're fine. Try to edit one, and after a few seconds, there's a final refresh of the image window that heavily alters and bands the colors. (Looks almost like a poor conversion down to 256 colors or less - it's that bad).
This is happening on Canon 300D and 20D raw files, and did NOT happen with iPhoto 5. The RAW files open up and display just fine in Preview (as well as 3rd party apps) - problem is in iPhoto 6 only. I've already sent in a bug report - has anyone else tried double-clicking on a RAW file to go into Edit mode yet?
David Miller

I use Huey from Pantone to calibrate my monitor for consistancy in different lighting situations and across applications. But the same effect happens by choosing any one of the non-standard monitor calibrations.
Try this:
Choose a RAW photo and monitor calibratioin that causes the banding and discoloration.
Open the RAW photo in Edit mode and wait the couple of seconds for banding to appear.
Next, adjust the image size slider so that scroll bars appear at the bottom and right side of the photo. It doesn't take much. Notice the banding disappears!
Now grab one of the scroll bars and move it. Observe the banding and discoloration. And, when you release the scroll bar the banding disappears again.
I don't remember this happening with iPhoto 5.
I think it has something to do with the display
calibration. After I first saw this I switched back
to my default iMac G4 profile, and the problem wasn't
there anymore. I'm not sure what the difference is. I
set up several different profiles, each with
different choices for Advanced, White Point and
Gamma, and some trigger this banding, and some do
not.
Anybody have any similar experiences?

Gradient banding on X220 IPS screen

Over on the Faint Ghosting on X220 IPS screen thread, I mentioned (twice, actually) that I see gradient banding on my X220 IPS screen. Nobody else has brought up this issue, and at the moment it seems that I may have a defective screen.
Here's a test image to check for gradient banding: http://www.lagom.nl/lcd-test/gradient.php. View and compare how it looks on other laptop and desktop monitors. Gradients appear smooth on my desktop PC (Dell monitor and low end Radeon card) and MacBook Pro, but banding is easily visible on my X220 with IPS screen. I even see faint banding when I view this forum, the subtle gradient background at the top of each post. My display is set to 32 bit color and 60 Hz refresh.
I'll take it up with Lenovo support. Meanwhile, anybody else who has the issue can post and discuss here.

I have the exact same problem.
When there is a gradient (like on the login screen, or the webpage linked earlier) I can see the image moving for a couple of seconds. This kind of behavior from the screen also makes my eyes painful after a while.
I love this laptop otherwise, but this is a terrible quality issue. I tried to explain my problem to lenovo with no luck.
Anyway, from what I read here, it's common to most x220, what can I do.
If at least lenovo was helpful. Or if they could let me return the laptop without the absurd 15% restocking fee...
Edit: Alright, found by myself after a couple of hours searching: The moving bands when the display is "adjusting" to the new picture is in part due to Intel's power saving tech "Intel Display Power Saving Technology" which can be disabled in intel's control panel. It causes flickering of the screen in general, but mostly gradients.
For those wondering, yes, it does save some power. The computer idling with this feature uses 10 watts. Without it's 11. I don't know how it'll affect battery life, but if I really need longer battery life, I'll turn the brightness down myself.
I still notice some flickering, I'll see how it goes. The banding, while now static, is still clearly visible though.
Maybe someday they'll learn LG is not good at IPS screens (see the ipad2 fiasco too)

Photoshop CS6 Color Management Inaccuracy

Adobe: Just a reminder, this color-management problem that I reported against Photoshop CS5 is still around:
http://forums.adobe.com/message/3475331
It's illustrated here in this screen grab, showing the visibly inaccurate result of Photoshop's transform, done in the GPU, from RGB values in the ProPhoto RGB color space to the sRGB IEC61966-2.1 color space. Note the circular banding and color shifts in what should be a perfect gray gradient.
Do you think you could find it in your hearts to fix this before moving on to layer more features on an imperfect code base?
Thanks.
-Noel

I would like to include myself in the list to request the Adobe Photoshop CS6 team to look into the discolorization issue. I am using the entry level nVIDIA GT 430 for its basic openCL features for PhaseONE CaptureONE PRO.
I created a 16-Bit monochromatic image in CaptureONEPRO 7 and opened in CS6. My RGB working profile is ProPhoto and my 16-BIT BW TIFF is in the ProPhotoRGB space. With the GPU settings to "Normal" and "Advanced," I could see the discolorization and banding on my images. I have found that if I go to "View" and click on "Gamut Warning," the discolorizatioin seem to disaappear.
Having the GPU to "Basis" clears everything up as Noel Carboni first reported. I only have the banding and discolored appearing when GPU is on "Normal" or "Advanced."
Yours sincerely,
Ronald

Dead or stuck pixel. well I got one

It ***** it is right in the middle it looks grey more than black or anything . I read some stuff but cant really figure out if there is anything to do about it. Does anyone know of anything to fix this? thanks

Some people have success gently rubbing the area around the pixel, others find running unstick_pixels.MP4 (1.5MB) for a few hours over the area can 'unstick' them ...
If it's black (dead) then you're unlikely to get it back, if it's a primary color (stuck) then it might kick back in.
If it's grey ... it could be discoloring in the LCD screen layer and not the pixel layer ?

Broken screen on iPod

I'm just wondering if there is anyway that I can take my iPod to a service dealer place and get the screen replaced. Is it even possible to replace the iPod screens?

if its the plastic front i wouldnt worry to much as long as it doesnt seem to bother you much. if its the lcd eventually it will crack more then bleed then become more of a pain to see. you should be able to see if its the lcd you will notice some discoloration on the lcd screen. eventually it will die, the lcd that is. they are easy to change out. i've done these models before. its a black and white screen right, same as this ipod..

External LCD monitors with DVI PowerBook: Banding Issues

I have a DVI PB and would like to attach an external LCD monitor. I've looked at both Samsung 20 inch and ViewSonic 19 inch versions but whenever I attach them, I get "banding" around the edges of the external monitor. Tonight, I went to CompUSA to look at the Samsung 204B 20 inch. Taking my PB with me, I hooked up and set the resolution to 1600 x 1200 and the Samsung had huge, fat black banding all around the monitor. If you don't know - banding looks like a large, black border going around the screen. The sales guy pushed some auto-set buttons (which is said always work to remove the banding) but it didn't fix the issue. Any suggestions? Is there some secret that I'm not aware of on how to attach and use an external LCD monitor with the PB? One note: I did set the resolution down to 1280 x 1024, which worked fine to remove the banding but it monitor looked horrible. Not the best resolution for a large monitor.
Thanks,

Hi, Bill. I can't speak to whatever happened with the Viewsonic monitor, since you didn't tell us about that, but it sounds as though the Samsung was in display mirroring mode rather than extended-desktop mode. The F7 key on your Powerbook's keyboard toggles an external monitor between the two modes. In mirror mode, the external monitor displays exactly the same thing as the built-in display. In extended-desktop mode, it functions as a separate portion of your desktop, and you can drag things (windows, icons) from one monitor onto the other. If you're going to use both displays, extended-desktop mode is probably what you'll want: why keep two copies of the same thing in front of you?
In mirrored mode, the fact that your Powerbook's display has a maximum resolution of 1280 x 854 means that only 1280 x 854 pixels of the external monitor can be used — leaving wide black borders of untapped pixels around the copy of your PB's display that's centered on the external monitor. In extended-desktop mode, the external display's native resolution of 1600 x 1200 can all be used, provided that your 32MB of VRAM is sufficient to drive the total of (1280 x 854) + (1600 x 1200) = 3,013,120 pixels, at the bit depth you've selected. (You might have to use the extended-desktop mode in Thousands of colors, rather than Millions.)
Another issue that comes into play with display mirroring is that the 4:3 aspect ratio of the 1600 x 1200 Samsung is different from the 3:2 aspect ratio of the Powerbook's display. If you set the Samsung's resolution to 1280 x 1024 to match the pixel width of the PB display, the top and bottom of the Samsung will be black bands, because the PB isn't manufacturing any pixels to fill those bands. And it will be blurry, because the Samsung has to interpolate to make 1600 pixels look (sort of) like 1280 pixels. Unlike a CRT display, the actual number of pixels in an LCD is fixed. When you change resolution settings on an LCD from its native (maximum) resolution to anything less, the image is always blurred. Only the native resolution can be really sharp.

Gradients showing with bands on new LCD

Hello,
I am not sure this is Fireworks problem and I would be quite
surprised if it is. I just upgraded changed monitors from a SamSung
CRT to a LG LCD. Now when I open my old source files containing
gradients - especially the vertical gradients - I see a lot of
'bands' or 'stripes' showing instead of nice smooth gradients.
I must say I just re-installed Fireworks (version 8) to fix
some file association problems but I would be very surprised if
this re-installation is what's causing the 'jaggies' in the
gradients. The fact that my old CRT still shows smooth gradients
tells me that's it's the LCD. But, I have also tested my images on
5 different LCD monitors, and I still saw the 'bands'.
Any thoughts would be much appreciated.
P.S. Using JPGs and PNGs for my linear gradients. Though the
'bands' are somewhat less visible in the PNGs than in the JPGs,
they are still very perceptible.

Dynex 32 LCD -Half of the picture goes green with a red band

Hello- I purchased a Dynex 32 LCD TV around Christmas and As a TV it was a great buy, however when I use it as a PC monitor using either DVI, VGA or HDMI connectors I get an intermittent issue with half of the screen. The right side of the screen (From the middle of the screen to the far right) will turn a light green, (almost like it goes 16 colors) and has a red veritical band from the top to the bottom of the screen. Sometimes turning the TV on and off will fix it, or changing pages on a web browser will cause it to go away, sometimes it just stays. Anyone heard of this issue? I use LCDs as monitors at work and I've never seen this happen before.

Sounds like it needs servicing. If you bought it in September it should still be under the 1 yr manufacturer warranty. You can bring it into the store with your receipt and have customer service send it to service for you. It will be returned to the store and can be picked up when service is complete. I will say, however, warranty service can be lengthy. Expect to not have your TV for a few weeks.

T410s vertical band in my LCD

I have had my t410s for a couple of months, yesterday a vertical band appeared in my display. A quick search online brought up this: http://www.youtube.com/watch?v=rM9_ZM_8qkQ
which is exactly what I see.
I am about to lose my t410s for a couple of weeks (or so I am told by the Lenovo support rep), is this a problem that Lenovo is able to reliably fix? (namely it is clearly endemic to the t410s as I have seen many posts on the matter, my concern is that their fix is just temporary until it happens again)
Do others who see this problem find that the repair sticks?
btw, I have to say that the Lenovo return mechanism which required me to talk to someone I could barely understand did not help. I used to love the Thinkpad line for its robust design (and had many), the T410s, which was not inexpensive, felt flimsy in comparison and having the screen die in such a short time is disconcerting (and seeing how many people are dealing with the same thing is a further concern).
Solved!
Go to Solution.

For the record: Technician came and replaced the LCD. Took maybe 10 minutes. Works perfectly now :-)
I asked him if he noticed anything about T410s displays failing and he was not aware of any issue with that particular model.

T400 LCD discoloration

Hiyas, I have a t400 2764-CTO and Ive noticed a Pink and Yellow discoloration in the bottom right hand corner of my LCD...
http://img100.imageshack.us/img100/6564/img2473r.jpg
I was wondering, what is the cause and how can I fix it? Is it a LCD problem, or a problem with the connector and if so if any of these things can be fixed with the warranty.

discolouration like this is usually the problem with the LCD itself.
This should be repairable under warranty, call 131 426 press 1 and then 3.
But you should put a 3M sticker note on the LCD telling them where to look for the problem.

Jin Li

Screen Issues - Scratch on LCD / Discolored Aluminum on left side

I purchased my MBP July 2008 ... I have handled this laptop with kid gloves. I've been seeing a few things that concern me as of lately. First, I have the matte screen which is developing a horizontal scratch (looks like from the sharp edge next to the space bar). As if that isn't annoying enough, on the left side of the screen, the aluminum between the LCD and the edge of the screen is starting to discolor in spots causing it to turn white. Originally, I thought that there was something on it, but this doesn't come off...It is as if the finish is damaged. What gives?
I spent a fortune on this computer and am shocked to start seeing things like this given how well it is cared for. I have Googled and common reasons for the scratch is applying pressure to the screen which doesn't fit my situation. The scratch on the screen is a little ridiculous as it seems to be getting worse with time.
Is this something Apple will do anything about?
Thanks in advance!

Okay...Now I need to give an update and ask again for help from the experts. At the same time I discovered my screen getting a horizonal scratch, my iSight camera quit working. I took it in to the Apple Store and they agreed to replace the screen as the hardware was faulty (broken camera) and sold me a piece of soft material to put between my screen and keyboard to prevent scratching after they replace the screen. I couldn't get it repaired the weekend I took it in due to their scheduling and the fact I live 100 miles away from the store. So they told me to bring it back to any Apple Store when it was convenient to do so and they would be glad to replace my screen as agreed upon. They noted the situation and I was set.
In December, I finally made time to have the computer screen replaced. Needless to say the tech who worked on it was either in a hurry or didn't care. Long story short, they gave me the last display assembly in stock which was warped and they didn't get the computer back together correctly because there is a gap on the rear of the display assembly on the left side where there shouldn't be one. Despite the mediocre repair, my iSight camera worked and they told me bring it to any Apple Store within 6 months and they would replace the screen again to make me "happy." This is after an employee at the Apple Store tried to convince me that my warped display was normal because of unavoidable manufacturing imperfections. My last display sat flat, so that excuse didn't fly. If I owned a Dell, that might be a different story, but I paid over $2000 for a machine and I expect better. Fast forward to tonight...I was going to get a iChat session rolling only to come to find that my iSight went out again (assuming another hardware failure). I know the screen is supposed to get replaced again down the road because of the poor repair job on the first go around, but how many hardware failures do I need before things work and continue to work?!? I cannot afford to drive 100 miles down to the Apple Store every 3 months because something else is broke. This is the second time the iSight went out for no apparent reason. What is the lemon law for computers?
I know I sound like a disgruntled Apple customer, but let me assure you that I'm venting. I love my MBP, but am disappointed with this situation and am seeking advice what to do about it.
I thought about trying to get my computer repaired at a local Apple Authorized Service Center where they order the part and fix it when the part comes in. I've seen their work for a keyboard replacement on a family members computer and it appears they do good work. Are there any downsides to having an Apple Authorized Service Center replace my screen for the second time?
Thanks in advance for any advice or insight you could shed on the current situation.
