Occasional pixelation on darker colors

I am having a display issue with my MacBook (mid-2007)
I am getting occasional pixelation on darker colors. The pixels turn redish/purplish/pinkish...If I press on the screen near the Apple logo (on the top cover) and on the lcd screen I can sometimes get the issue to go away. When I plug in an external monitor the pixelation does not show up on the external monitor but will stay on the laptop lcd display. I do have windows also installed and the pixelation shows up in windows as well....
So my thinking that it is likely an issue with the LCD cable or LCD dispaly....
I don't mind taking on a project...I have no issues trying to fix this thing myself...Any thoughts of things I should check or try?

Well...I was curious so I took the LCD bezel off and removed the LCD and bracket. The issue is with the data display cable or the LCD screen. Tapping/pressing on that connection clears up the issue for a bit. Is there a way to "tighten" up that connection? Any thoughts anyone?
Thanks!

Bright Pixel on Light Colored Backgrounds

Hi fellow Mac Friends,
I have a quick question for you all that has been bugging me for over a month. I recently bought a Mac Book Pro and it came with a beautiful LCD screen with no issues. A few weeks after I bought it, it developed the awful whine that everyone was talking about. I took it to the Apple Store and they fixed it within a couple of days.
Great!
However when I got it back, a week later I noticed that now something was wrong with one of my pixels. The pixel is not stuck (Red/Green/Blue) nor is it dead (black or off) as far as I know. The pixel is bright but not all of the time. It is only abnormally bright on light colored surfaces and its brightest against white. Now as you know, most web pages have nice white backgrounds so this is painfully annoying. Emotionaly its hard to swallow after I just dropped so much money but the the impefection is painfully clear.
Despite my feelings on the subject, I was hoping someone else might provide some information on this. Is this a "dead" pixel? Or a "stuck" pixel? Or is this something fixable. I have tried all of the stuck pixel programs out there but I don't believe this is a dead or stuck pixel.
I have heard the term "hot" pixel but then I would assume that this pixel would burn white in all situations including dark backgrounds.
If there is any information out there that someone might know on this subject, I would greatly appreciate it!
Yours Truly,
Rilely

Right, that particular pixel would not be able to render all the colors. With dark backgrounds, the pixels are shuttered and not passing light. So even the sub-pixel where the color filter material has chipped off will not be illuminated and showing brightly. It will only be for certain colors and white where the brighter-than-bright pixel will show. You should be able to use a test program and determine which sub-pixel, R, G or B, has the missing color. Just put up successively an all red, all green and all blue screen. One of those screens should have a white pixel. If, for instance, the red screen has the white pixel, then it is the red sub-pixel that is missing it's color filter layer for that particular pixel. Here is a link to my favorite freeware program that can provide the required test patterns:

How to avoid darker color behind a gaussian blur effect?

I have used the effect gaussian blur with black text on top to make a logo.
My problem occures when I try to place the file on a coloured background e.g. a photo and print it. A darker colored area appears behind the gaussian blur. The logo is to be used by others and hence I would like to keep it a vector/illustrator file (not a pixelated photoshop file).
- I have saved it as an ai
- I have all the artwork in one layer
- I have tried object > flatten transparency (but then the area turns white)
- I have tried effect > Document raster effects settings (resolution 1200 dpi / add 35,28 mm around object)

- I use Illustrator CC v. 17.1.0. 64-bit
- the file is cmyk and I only use process colors
- the line is 8 pt and effect is applied with 8 px blur
- everything else in the document is outlines and some text and lines are crossing the blurred object
- color settings: European coated offset ECI
I hope I haven't missed anything. The logo is not launched, but I have enclosed I photo file that is similar and where the same problem occur. The file is placed in InDesign on a blue square and printed from InDesign to a OKIC8660 laser printer.
The light blue to the left is the correct color. The darker blue is not supposed to happen. The yellow is where the gaussian blur is applied.

When painting a light over a dark, at low opacity, i am getting an even darker color. How to fix?

I'm using version 1.4, running on a Samsung Galaxy Note 10.1. Both when I set the pen pressure to opacity control, and when setting the brush to an overall lower opacity, my light color turns a reddish dark where it overlaps my dark color, almost as though i'm using the burn tool. i havent noticed this problem before, and i've been constistenly using pstouch to paint, since i bought this tablet nearly 3 weeks ago. I'm painting a dark muted orange over a slightly darker, slightly more intense (but still mainly muted) red. It looks almost like a watermark effect. each transparent brushstroke has sort of a fringe around it where it looks as though simulated pigments collect in a concentrated way, creating a dark ring around my slightly less dark brush mark.
This might be related to a color picker problem i have consistently noticed. it seems that the color picker tends to pick darker versions of the colors i sample. this might have something to do with the fact that my brush is usually set up with less than 100% opacity, and maybe, for some reason, the color picker is programmed to compensate for that. In any case, the color sampler doesnt work fully as it should, and this obviously affects my ability to use lowered opacity to blend colors together.
That said, even when i sample a color, then manually lighten it to match the lightness of the sampled color, i still get a burn tool effect when making transitions between my slightly darker and slightly lighter warm mute dark colors, using a color with lowered opacity. the only way to make the lighter color lighter than the darker color, is to simply bring it to full opacity, but then i get no transition between the the colors.
I assume this is a bug that needs to be fixed, but if anyone knows of anything i might be able to do in order to solve this problem, I'd really appreciate it.

Actually, here's a clearer image. The middle stroke is with 20% drawing smoothness, and 100% pressure strength.
The top stroke is 100% both, and the bottom is 100% drawing smoothness with 20% pressure strength.
In all three instances, the dark watercolorish ring persists.

Problem: eyedropper tool gives me darker color

Hi all, I hope someone can help me with my problem. I'm on motion 3.0.2 that i have been using for a while but now I have a problem I can't find an answer to. For the past months, the eyedropper tool of any color property and effects gives me a darker color than what I click on. It's the same color but darker, a real hassle when trying to match two colors. Help anyone? Thanks

I've noticed this at times. I have no solution.

XH-A1 dark colors

hey
just got done shooting some footage with out brand new XH-A1 and was disappionted with the "dark colors", especially black and dark blues that didn't turn out...
they look grainy when played back...what's the reason for this?
all other colors look great and sharp, but the blacks just aren't up to par, is that due to insufficient lighting and if so can that be corrected through settings in the camera (white levels?)
appreciate any help...just getting into this stuff....very exciting!
Thanks
~Will-i-am~

hey
ok...I guess I'll just start asking the questions then.....
when shooting in low light situations how do you eliminate the graininess?
what settings have to do with graininess in low light situations?
I'm guessing there are no filters you can add during editing to help this?
Thanks

How do I change beige tabs with white text to beige tabs with black (or some other dark color) text?

Classic Restore changed by FF 29 tabs to beige with black text on the active tab and to beige with white text on the other open tabs. The white text is not visible. How do I change the white text to a darker color?
If this cannot be done, is there a way to reinstall FF 29 with just the security updates (and not all the other gimmicks) so that I can retain my FF 28 settings? Thank you.

# Open the Add-ons Manager (Ctrl+Shift+A; Mac: Command+Shift+A), then the Extensions category.
# Next to Classic Theme Restorer, click the Options button.
# Click the Custom Colors tab, then the Tab (active/hover/default) tab below that.
# Below Tab (active), check "Text", then click the color swatch and pick black.
# Click the Tab (unread) / New Tab tab.
# Below Tab (unread), check "Text", then click the color swatch and pick black.

Canon Pro9000 Mark II prints dark color tones muddy on gloss paper

Boss accidentally bought gloss print paper, but I figured that might work out for our art renderings. However the ink bleeds... strangely, only on dark color tones. Image is below. It's a Canon Pro9000 Mark II. It seems to be dark tones that bleed only. The light gray is perfect, and even a well-saturated yellow-orange looks decent. It doesn't appear to be the saturation or amount of ink that is the problem, but the darkness of the color. Is it the printer, the paper, or the ink? Is there a solution?

It really doesn't matter if you don't have the proper profile for the paper. Do you? If not you really can't use that paper at all. You might try to see if another profile will work but that is mostly fool's play. The correct profile is mandatory. Most good paper suppliers provide the correct ICC profiles for their paper. Canon, Red River, Moab, Artic, etc.

IMovie '11 Exports are distorted with dark colors.

Hello everyone, I have a bit of a problem with iMovie 11 exports. I usually capture video games with an HD PVR (.mp4 files)
Once I import those videos - without converting them to .mov or any DV formats, I edit, export, and save the video to my desktop. However, once I watch the videos- no matter what format I save it in- the video comes out a little disorted, or blurry, and you can specifically see the problem with the dark colors and any darkened spaces in the videos. Anyone with the same problems/solutions?

The blurry video is likely caused by the de-interlacing of the video. iMovie doesn't handle interlaced video properly where Final Cut Pro does.
The dark color are likely caused because you are comparing a video from your television on your computer screen. Video on the computer screen always looks much darker than your television. They are different color spaces, TV (yCbCr) and Computer RGB.

Cannot read track number box if using dark color configuration

The color options are fantastic in 3.0 but for one single problem. If configured to a dark color - I use a very deep blue - the Track number box in multitrack mode cannot be read without putting the cursor in the window (then it blinks brightly because it is highlighted and ready to be relabeled). It seems that it needs to be programmed to show against any color configuration, without having to place the cursor there.

>So who decided to "fix" it?
Hmm... this all happened with AA2.0 initially - and that was done to an Adobe corporate (grey) plan, to all intents and purposes. There are some things that are bigger than all of us, it would seem...
I suppose that in an ideal world, a lot of people would say that being able to 'skin' Audition would be the answer, but that doesn't really do it for me, I'm afraid. My attitude to this is quite simple; Audition is a tool, and I don't care what colour it is, as long as it works properly. Yes, it should look okay, but mostly that's to do with being able to see what's necessary at any given time, and by and large, I can.
But, doing what you want could be regarded as an option, and as I've said elsewhere, I think that options are a Good Thing. The only snag is that I rather suspect that more colour options will come some way down the priority list -
unless, that is, they are easy to do. In that case you perhaps stand a better chance!

Screen covered with green and blue pixels (visible on dark colors)

Hello,
I have this tablet since beginning of April, and since few days I've noticed the little dots on the top of the screen.
From far away it looks like dust behind the screen, but by having a closer look, it's like pixels that stay green and blue when the rest of the image is dark.It's very visible when I'm using the tablet with no lights around me. i've tried to restart the tablet, and even when It's loading with the SONY sign, I have that! what should I do ? Did people had that issue before ?
(BTW, The screen is also unresponsive when plugged to charge)

I encounter the same problem. I bought my Z2 tablet 16GB from the Singapore Sony Store. I got it for one month and the same pixel problem appeared. I send it in for servicing at the Singapore Sony care centre at 313 somerset outlet.. One week went by and nothing happened. The service was bad, no reply from the customer care or technician. They gave me a website so i can check the status of the servicing but all it shown on the page was pending.. one full week and still pending. I had to call them once and asked them what happened, the Sony personal over the line could only say they can check and get back to me. The next day i called again to check if any technician has even start and immediately right after that they called me to go down to collect. Turn out they are giving me a new tablet. And the screen protector was not refund to me as they said that the device was still in the service centre.. had to buy a new one for myself. Such a disappointment in the servicing.. and now the current one i am holding as the same freaking problem.. also i notice the corners of the screen has some yellowish hue.

Late 2011 Macbook Pro green pixels on the screen where dark colors should appear.

I have a late 2011 Macbook Pro I bought it new with 4 gb of ram. About 4 months ago i purchased 8 gb of pny ram for this model and upgraded the ram. I followed all of the safety precautions and discharged my static electricity before upgrading. It increased the speed of my mac and helps with certain tasks. About 2-3 weeks i notices my mac froze and strange green black and pink bars appeared on the screen so i hold the power button to shut it down and it solves the problem this will happen about once a month but otherwise my mac works perfect. Now about a month ago I powered my mac on and low and behold The screen was covered in green pixels. I tried rebooting twice and it didn't do anything then i let it sleep for about 5 mins opened my mac and the green pixels were gone. Now my mac is still usable and everything works its just sometimes like once in a while ill get a few pixels and closing and opening my mac fixes it. I was curious if this was related to one another or is my mac just starting to die....

I have been getting green pixels/boxes the last while...
I have noticed it after waking the machine from sleep. Not 100% sure if that is the only time it happens. It goes away after a few seconds, typically.
Any idea what is going on?

Gif images, pixels and hex colors

I'm not a java developer, though I at least have attempted to learn it. This may be a strange place to ask this question but java keeps coming up in my search so what the heck!
I am a highschool biology teacher-to-be and I am trying to design a lesson about DNA transcription and translation. I want the students to play a game where they take hex color codes (codons) and place a color card (amino acid) the hex code represents so that they build a big pixelated picture (the protein). I don't want to do the work of writing down the hex code for each and every pixel of the image, and was hoping there was some way to reveal as a list the hex color of each pixel in some sort of ordered fashion. I tried just dragging a gif file into a text program, but that didn't do it, ha!
Any ideas?
Thanks

When I am streaming videos there is a dark green tint to the darker colors on the screen.

When I am streaming a video, there are dark green shades to some of the darker areas on the screen. For instance if someone in the video has dark hair, there are green tints to the hair. It almost looks like a color negative, but not quite. This has just started happening. I've had my mac book pro for about 2 months.

Could you please give us a picture of what is going on. This is a picture of what the top of Safari looks like when I go to the Help menu. I typed in the word cache and a number of options appeared below. Is this not happening for you?

CS3 PRINTING VERY DARK COLOR PRINTS ISSUE

Hi,
This is the situation:
I work on an Eizo CG241W calibrated monitor, and Epson 9880, 9800 and 4800 printers profiled with i1 PRO and EYE-One Match Software. But recently we made a move from Windows to Mac, and since then the color prints are being printed much darker then they used to. I havent been able to figure out was causing it. The issue is the same with all printers.
With the black and white prints printed in Advanced B&W and selecting "normal" (not dark, or darker...) they come out perfect. Just as in the screen. But not the color prints. I need to make them really look very very light on screen to get them where they should. Before I needed to make them lighter, but not as much as now. Same images and files Im talking about. Ive used Epson canned profiles and im having same results, variations, but as dark as with the created profiles.
Thanks for reading and any help on this.
Best,
Alex

Hi,
Thanks Seth, Ballard, Lundberg, and everybody.
The problem has been solved but the mystery remains.
The issue wasnt in the steps needed to print. Thats what I do in the studio where I work most of the time. We calibrate monitors daily and the printers every month more or less. Ive been doing it here for over a year with no problem. This started when we changed platforms and equipment.
However, tired of this, we decided to wipe out clean the printers mac station. Reformat, reinstall all software and drivers, reconfig, etc. And now is working. What was the problem? Who knows.
Thanks again to all,
best,
