Blotch on display

In the lower left hand side of my display there is a redish (when on a white background) blotch, that is see through, but reveals an uneven color quality on my screen, how can I fix this, or should I return my whole laptop?

I have a similar issue. On the menubar at the top of my 13" Macbook Pro, there's a reddish tint towards the right of the screen and a few pixels that appear slightly "blocky". The tint makes the color of the menu bar inconsistent from left to right.
I got mine right around Thanksgiving, but it looks like I'll be needing to take a trip to the Apple store...
What ended up happening with yours?

Blotches on display due to pressure

I was going to search for this first and then add to an existing topic (sure there must be one), but since the search facility has disappeared.....
I'm now on my second replacement screen for a 15" MacBook, which has been due to strange blotches appearing on the screen, a little like fingerprints, and more noticeable against a white background. These were in the centre and were a massive distraction when working on graphics etc.
When I last picked up my Mac, the guys at the service centre stated that they'd appeared due to pressure against the screen when the lid is closed. I cycle with my Mac, but it's in a very, very well padded Crumpler rucksack. It couldn't be any more protected.
The engineer showed me the insides of another screen/lid which had five or six little white pads surrounding the apple logo, and said that it was the pressure of these on the screen that had caused the marks.
This was only a couple of months ago and i'm now starting to very faintly see two more marks appearing on my brand new screen!
Can't complain about the AppleCare service when it came to the replacement, but how many times are they prepared to change this screen... is this something I've just got to accept?? I'm really looking after my Mac, I love this machine, but sometimes I despair about the quality of some of the components (and Apple's updates (10.5.3 for killing my Airport for example)).
Any comments/advice?

it is fairly new, better than my last bag, which was also good, but the problem occurred nonetheless. this crumpler bag couldn't be better padded, and the MacBook is meant to be portable... so what should i carry it in??

White blotch on display when dock is in view..??

When the dock is in view, there is a small white dot ( a lot bigger than a deal pixel) no matter what background i have. When the dock is hidden the white dot is not visible but when the dock comes up again it appears.
Can someone explain this to me?

Have you tried restarting your computer? Also, where is the white dot on the screen? And, create another user account (on Mac OS), and see if the same problem exists on the other account.

Display Problem on MacBook Pro 13-In: red blotch when screen is dark/black

I've been having a really weird problem: a red blotch near the center of my screen, visible if the screen is black, or dark background in video playback. It's about an inch off center (right) and it look like a "T" made by a paint brush stroke. When it first appeared (in the same spot to the left of center), Apple replaced the display (in the last year of Apple Care), and it disappeared. It reappeared 4 weeks later as clear lines (in the same spot). They replaced the display again, and it disappeared once again. It happened a third time 4 months after that, and they replaced the logic board as well as the display; again, "fixed." Here's the weirdest part: because, after all this, the computer would not charge, they threw up their hands and gave me a brand new MacBook Pro. That was a month ago, and last night, there was the red blotch again (except now, again, just to the right of center).
I can't find anything like this (online) happening to anyone else, and so far Apple hasn't determined what they think the problem is. I sort of feel now the problem must lie with me. But what could I be doing? I haven't dropped it; I'm just using it for email and reading online.
Anyone have any idea what this might be? Thank you very much in advance for any suggestions.

I can only do wild guesses at this popint, only thing I can think of on your end is possible AC power problems, but I've not been impressed with Apple's quality since the 68K or Beige days.
THe iMac7,1 I'm on now needed repair 3 times & still scares me with it's PSU temps.

Display 'blotches'

In the bottom right hand corner of my 20" 2GHz iMac G5 small bright blotches are appearing behind the display. These are more visible when there are ligher colours displayed on the screen.
There is also an area of the screen that is visibly brighter on the bottom left hand corner, about 5-10mm above the bottom edge of the display. This is more uniform than the other blotches.
A screen capture dosen't show any of these problems.
Can anyone shed any light on what this might be and how i might be able to cure it?
iMac G5 20" rev. B Mac OS X (10.4.4)

I also have this problem, still looking for a cure...
But my Imac is out of warrenty so I guess I'm stuck with it.

Large blotch appears on display

I have an iBook G4 which Apple replaced for my G3. The G3 was part of the extended logic board program; they tried to repair it three times but were unsuccessful. I've had the G4 for less than 12 months. I've never had a problem with it until today. When I turned it on there was a very large blotch of black and white in a free-form design covering 3/4 of the screen. I tried to restart, then shut-down and restart but nothing got rid of the blotch. I can see the outline of the blotch when the machine is off. Is this another logic board problem? I wrote to Apple and am waiting for their reply.

Not correct. You received a refurbished G4 as a
replacement for your G3.
Hmmm... Interesting concept. According to the
Customer Relations person who sent it to me
originally, it was new. According to the Customer
Service guy my husband talked to today, the only way
to get a refurbished laptop is to actually purchase
one (and he said he couldn't look it up by the S/N
because once it was registered to us, all he sees is
our info.)
Then this is an even better reason to buy from Apple. In the electronics industry, it is standard practice to use refurbished components when repairing/replacing defective one. That is what is written on the fine print of every RMA I have ever seen. That doesn't mean they can't or won't give you new parts for a repair or replacement. It just means if they do, they are going above and beyond anyone else. And, for what it's worth, I would take a refurbished Apple over a new PC any day. I am a proud owner of an Apple-refurbished iPod - works like a charm.
This whole discussion has re-lit the fire in my
husband and he is pushing the issue now (it is still
under warranty until Oct.)
Squeaky wheel gets the grease. I just think that if you had one of the lemon G3 that had to be repaired 6 times and finally replaced, and the replacement screen cracked, they should give you a new machine. You've suffered enough.
We would have purchased what instead?? A PC? And
perhaps run Windows on it?? (excuse me while I pick
myself up off the floor from laughing.)
That's nice to hear to a change. Usually it is something like - "I bought this first generation MacBook and it has a funny noise and runs hot. I'm filing a class-action lawsuit!!!"

Green-ey/White-y blotches around perimeter of screen when displaying black

Just re-hooked up my imac g5 which i sold to my dad 9months ago - in that time he hasnt used it! i know kinda what was the point in buying it! so rather than leaving it to rot in a corner, ive set it up so that i can watch the off dvd etc... (i now use a 17' powerbook for all my work)
i put on 24 and immedietly notice subtle light blotches around the perimeter of the screen when in black. Almost light green/white colour.
i dont remember noticing this before... perhaps the screen is on its way out? i still have 2 months left of the apple care so at least i can get it repaired if a major problem.

anyone got any ideas?
to narrow it down a bit, i think its the light emission that is causing it around the perimeter of the screen.

Nano display

My Nano display has a "blotch" on it and nothing else can be seen. I have reset it and nothing. I have restored and still nothing. Ideas?

The "blotch" looks like an explosion from the inside, a water mark. It is only 1 week old. I can only see the "blotch" on the screen, the background is white, but no words or letters. Not using anything else on the screen and it had been working up to a few days ago.

Issue with Macbook Pro (Screen Blotches)

I've got these issues with my screen, these bright marks appear when the screen displays dark colours, and I don't understand what's causing them.
I've got pictures of the problem here.
http://s891.photobucket.com/albums/ac118/zupnik/?action=view&current=screen1.jpg
http://s891.photobucket.com/albums/ac118/zupnik/?action=view&current=screen2.jpg
You can even see black dots in the actual marks themselves which I don't particularly understand. But will this be covered under my warranty? I haven't spilt anything on my Macbook and it hasn't suffered any knocks that I'm aware of.
I've checked the forums, but the other "blotches" which are mentioned are seen in light colours, whereas I can't see them at all in light colours.
Please give me some advice.
Thanks,
Anthony

I have exactly the same problem.
But since I download the las update, everitime i conect it both displays just turn black and i just see the mouse's pointer.

Images with black blotches showing up.

I have a wierd problem with picture quality that just started showing up.
The black detail in certain areas of the picture is becoming overly black. Blotchy black areas especially on the screen and in prints. Black detail becoming overly compressed. The gradation between light and dark on my 23 HD and 17 Cinema display shows as layers of black, not a continual gradation to black. To explain it another way, the gradation of black colors (when going from light to dark to black) appears on the screen almost like Newton's Rings. I'm starting to get blotches of black in the darker areas of my monitor images and now on the prints. All the pictures are RAW (shot in Adobe 1998) from a Nikon D70s. None of the images have been altered in any way. No color correction, exposure increase or decrease, nothing. Straight RAW files imported directly into Aperture from the camera. I have printed all these pictures before and they looked fine. Now they have these black blotches in them. Not all pictures have the problem but the ones that have the darker black gradations (primarily to deep black).
I have a custom .ICC profile I use for printing and the monitor was calibrated too, using ColorVision tools. Spider2Pro and PrintFix Pro. But even is I use the standard profiles for the monitor and the printer, it's still the same.
The wired thing is, if I open the image with an external editor, Photoshop CS2, I do NOT get the same problems on the screen as I do with Aperture. (I have not printed yet from Photoshop CS 2 since this started, only viewed.)
This is just a recent problem, and as I said, I have been printing the same pictures before and viewed the same pictures before with no problems. I noticed this starting to happen after the last 2 updates for Aperture, and it has progressively gotten worse.
Any picture that has a continual gradation from a light black to dark black to full black has this problem. (On a 9 zone gray scale - say zone 5 thru 9)
Equipment Notes: Aperture 1.1.2, Mac OS 10.4.7, Apple 23 HD display, Apple 17 Cinema Display, Dual 2 GHZ PowerPC G5, 3.5 GB RAM, 2 SATA internal Hard Drives, (the one with Aperture has 30 GB's left on it and the other that I use as Vault Back-Up has 164 GB's available. Video Card - ATI Radeon 9600 Pro, AGP bus, 64 MB RAM
Epson Printer - R2400, using K3 inks on Premium PhotoLuster paper.
Does anyone else have this problem? Do you know how I send this problem to the Aperture Team?
P.S.
I too have notice a tremendous slow down in Aperture as of late as other people have stated.
I too sometimes don't get a image in the viewer. I sometimes only get the Right half of an image in the view. I can get other pictures to the left and to the right of the image in question but Aperture sometimes just picks a picture to only give me half. I must shut down and re-open Aperture to get the complete picture on the screen again. I can't figure that one out.
Thanks,
Jim

Well, besides my 2 previous posts, I would like to add something. I started printing and everything was going well once I turned On Screen Proofing off.
Oh, I guess I must first point out that I have calibrated my Monitor and Printer, using ColorVision's Spyder2Pro for the monitor and their PrintFIX Pro for the printer. It looks pretty good. But here is the problem.
As I started to say, after I turned off On Screen Proofing everything looked good, on my screen and my prints. I started to print using my Colorvision settings and my custom ColorVison printer profile. It worked for a while on some prints but I ran a print with a long gradation of black to deep black and that replicated my original problem. Blotchiness and striations of black. I found that if I printed with Epsons' ICC profile it was fine. So the ColorVision profile didn't work on some prints with deep gradations of blacks.
So I called their tech support. They asked if I did their 225patch target or the more extensive 700 patch target (I'm not sure of the correct number of patches). I had done the shorter 225.
They told me this is a common problem if you only do the 225 Patch Target and that I would have to do the 700 Patch Target to not get black patches/striations in my prints. As a note: the striations looked exactly like the On Screen Proofing problem when it was turned on.
So as it turns out, I had 2 problems at the same time.
I haven't done the 700 patch test yet. I'll let you know when I get it done, how it works out and if the On Screen Proofing matches the print as suggested by firstlaunch.
thanks for all your help and suggestions!

What is causing lines in display and scrolling hangs

I have a 24” IMac, 2.16 GHz Intel Core 2 Duo with 3 GB of RAM. The following problems exist and they seem to be getting worse. I regularly get thin lines, sometimes of different colors, across the display. This happens with and without open windows. In addition, I often get irregularly shaped blotches of colors appearing in the display in windows or on the bare screen. Small swatches of distorted text show up from time to time in whatever I happen to be working with.
In addition, the machine regularly hangs when I scroll up or down in various windows. It seems to at its worst in web browsers—Safari, Firefox, Camino.
I have run, and passed, all of the tests available with TechTool Pro, I have optimized the drives, and I have reinstalled Leopard. The problems persist.
Help please.

Please see this thread:

It might be the logic board, but indications are that it's an overheated graphics card. I have the exact same iMac you do (even with 3 gigs memory upgrade) and have similar problems.

Dark blotches - Imac 27"

I have dark blotches in a large area of the upper right corner of my display on my Sep. 2010 IMac 27. Any one have a similar issue?

MBA external display video playback

I use MBA 2012 with Dell U2413 via miniDP to DP cable avilable from Dell. Everything works perfectly, full resolution and sharp image. Only thing that bothers me is when I play video in any program including from youtube. There is a purple blotch where ever video is playing (MBA or Dell). This's not a problem when not connected with external display. How to fix this problem?
Any suggestion is much appreciated.

Finally, I came up with the solution, the problem is at Dell monitor setting. In Display settings, Smart Video Enchance, turn it off completely solves the problem. Hope this may be useful for those having same problem as mine

10 bit colour display path for lightroom 3??

I have been following an interesting forum topic on the PS forum here about 10 bit monitor support in PS CS5.
For some background:
10 bits/pixel is becoming more prevalent with high-end displays these days (it provides 1.07 billion color possibilities instead of the 16.7 million colors available with the regular 8 bit display path). Getting a fully working 10 bit path from the app to the display appears to be more of a challenge though, but a challenge which appears to have been overcome now in PS CS5. I'm wondering if moves are afoot for Lightroom to also support the 10 bit color path??
This is my take for what you need for PS CS5 to display 10 bit colour in windows (sorry, I'm not a Mac person so couldn't comment):
Suitable graphics adaptor - Some ATI FirePro models and nVidia Quadro models support 10 bit color (cheapest is nVidia Quadro FX 580) - the availability/use of the displayport interface is most often the tell tale pointer as to whether the adaptor supports this. Only more recent driver packs provide 10bit API support for apps to utilise, so latest drivers are often required.
Displayport connection between graphics adaptor and monitor (DVI only supports 8 bit color)
A monitor which supports 10bit color - (High end NEC models (PA241W/PA271W models and new Spectraview Reference models in UK) now support this as does the HP DreamColor plus some Eizo and Lacie models to mention a few)
Enable 10bit color support in the Graphics adaptor control panel - this option generally only appears when all of the above is in place, and when enabled, provides the display path via OpenGL, for apps to utilise if they are coded for such (this option is known as 'Enable 10-bit pixel format support' for ATI, and 'Deep color for 3D applications' for nVidia)
Enable OpenGL hardware support (under Preferences, Performance, 'Enable OpenGL Drawing' in PS CS5)
So will this be supported in Lightroom 3 before long? Or perhaps it is already??
Anyone know this?
Thanks, Paul
p.s. I realise the above chain of requirements sounds complex, but I got it working this week for a new PC build and it was actually quite straightforward.

What would be the advantage of this?
If you google around for how many colours the human eye is able to distinguish, you'll find scientific research quoting numbers around 10.000.000.
Horribly false.
The prevalent sRGB color space is covered fairly well by the 8 bits per pixel depth most commonly used ("32 bit" or "True Color" color in Windows), and that is about 16.7 million colors. While bit depth and color space are different things, once you go to the wider gamuts in other color spaces such as Adobe RGB without using more bits you will start to see banding in similarly colored (blue skies is a good example) areas because there are not enough digital steps to make smooth transitions as the color gradually changes. Take my word for it (I've seen it in many of my own pictures.) or do more reading for more details if it's not clear, but the key points follow.
First go to:
http://en.wikipedia.org/wiki/XvYCC
and read about the xvYCC color space. In their reference number 2 down toward the bottom of the web page you find a link to:
http://data.memberclicks.com/site/hopa/2007_xvYCC_forHPA_FINAL.pdf
which is a pdf of a presentation discussing extended gamut color spaces. Check out slide 3 which is at the bottom left of page 1 to see examples of many things in the real world that are quite visible to humans but outside of sRGB.
Next check out slide 19 at the bottom left of the 5th page to see just how pathetic sRGB is at covering human vision. The small pictures on the right in this slide show the coverage of the various color spaces of the "Munsell Color Cascade". The gray areas indicate colors that each space cannot cover, and you can see sRGB has huge blotches of gray.
Munsell did some of the very early definitive lab testing of human color perception. You can start reading about him and his color system here:
http://en.wikipedia.org/wiki/Munsell_color_system
and continue reading other links found on that page for more info about the extensive lab testing of human color perception.
Looking back at slide 4 on page 1 of the presentation linked above you will find an odd looking colored region that is curved around the top. It looks like this:
That colored region is the estimated range of standard human vision. There is a version of that which has the sRGB color space shown on it at:
http://en.wikipedia.org/wiki/File:Cie_Chart_with_sRGB_gamut_by_spigget.png
And that large view also gives you a much better idea of just how pathetically inadequate the sRGB color space is at covering human vision. Again, bit depth is not color space, but 8 bits per pixel is pretty much maxed out trying to represent the sRGB color space without having to fake colors within it's triangle.
There are probably cases where banding can be seen even in purely sRGB images with only 8 bits per pixel. And every color that you see in that large region with the curve at the top (in the picture shown in the last link above) that lies outside the sRGB triangle will have to be "clipped", which is converted into some color that does lie within the space. That means you never see any actual colors that fall outside the triangle even if 8 bits per pixel could have covered them somehow using some other color space. They're simply lost.
If you do try to use 8 bits for wider gamut color spaces you end up with the banding I mention above because there are too many shades of color to be represented by 256 steps for each of red, green, and blue. Thus the need for 10 bits or more per pixel.
I hope this helps to dispel any more myths about the limitations of human vision falling within what 8 bits per pixel or sRGB can provide.

IMac Aluminum 24" with yellow horizontal blotches

We have an out of warranty iMac 24" with yellow/dark horizontal blotches on the screen. The closest I can describe is that they look like residue from someone smoking around the iMac and the internal air currents have deposited the smoke/tar onto the inside of the screen.
But since we do not smoke this isn't the case.
Is this a similar ongoing issue that I read about the 27" in that it is the screen and not some sort of haze forming on the inside of the glass panel?
Has Apple acknowledged this as a problem and issued an extended warranty or recall or is this down to the old 'squeeky wheel gets the grease scenario"?
It is most obvious with a bright white background but less so once you have a darker pattern up. Still makes me think it will throw off any colour correction being done and since we're talking prepress work....
Thanks
Kevin

This is sounding similar to what i am now experiencing. Bought the Mac in early Sept, this started yesterday (Nov 17th), after "waking up" my computer from sleep mode out of no where. I have a 27in iMac, noticed - what I thought were smudges or dirt in the upper right portion of the screen. It's not, right now as I am typing on the white page I see slightly light yellowish spots, blotches, one looks like a 1/2 inch "drip" pattern.
Appears it's apparently spreading as well, the upper middle, and upper left I am noticing it now as well. Yet the center and bottom of my display is fine..so far.
This is not the first post about this issue here, so there is an obvious flaw.
I bought the AppleCare, "One on One"..so I suppose I will try to get in touch with them Friday. What upsets me is this is my FIRST Mac..dealing with Windows since March 1994 until I simply had it with them. Never once had screen burns or issues with monitors.
I love this Mac, but darn this is not the great 1st impression.
