Display Color Resolution

I have a remote application that needs the equivalent color resolution of 24 bit or 64 bit on a Windows machine. I cannot find a similar selection on my MAC display settings; just something called a color profile. Is there a way to change that setting on a MacBook to be compatible with the program I need to use? Thanks.

24-bit is the default setting of OS X. Under Displays Preferences it's called "Millions" of colors.

Display Color/Resolution Issues on Macbook 2.1 running 10.6.8

My macbook 2.1 (late 2006) is having display color issues. Computer starts fine but when it loads the desktop, the display seems to be mismatching colors and at a very low resolution. The error can be corrected by plugging in/unplugging an external display. Adjusting other display settings does nothing.

Hi Beeble80,
If the colors appear to be inverted, a function of Universal Access/Accessibility may have been inadvertently activated:
Apple Support: Mac OS X displays inverted image colors (white on black, reverse type)

If the display issue you are seeing is something else, you may find the following article helpful:

Messed up color display and resolution because of mini-DVI to video adapter

Once I connected the mini-DVI to video adapter to the tv and got weird colors on my screen for a while but then it worked out, then after a while I disconnected the cable and turned my computer off. After that, everytime I turned my macbook on, the color is fine for two seconds and then it turns into a weird offset color, really bright colors, kinda sketchy and just a few colors, and a weird resolution and display obviously, but then I just connect my Mini-DVI to video adapter and disconnect it again (quickly) and the color returns to normal. How can I make the normal colors stay and not have to connect the mini-DVI to video adapater everytime I want to see the normal color display and resolution??
please help!

Open the Universal Access pane of System Preferences, click on Seeing, turn off the White on Black, VoiceOver, and Zoom options, and drag the Contrast slider all the way to the left. If the issue persists, create a new folder on the desktop, drag half of the items from the Library/Preferences/ folder of the item in the Finder's sidebar with the house icon into it, and narrow down the files until you've isolated the one responsible.

How can I reset the screen colors/resolution on an old white macbook?

My screen shows neon colors and a zigzag shapes. How can I reset the color resolution? This laptop was supposedly fixed but when returned all my data had been "lost". The certified mac tech said he reinstalled the OS but lost all my desktop files and HD and couldn't recover. ODDLY, when I started the machine and started fresh, my old hard drive was still there! Although he'd wiped out my current desktop files- gone. But, the screen colors went wonky all of the sudden and I don't know how to resert or correct the resolution. Can any one share a suggestion?

With that kind of issue after returning from a repair where a tech was inside the computer, it should be returned to the same place for an evaluation of the problem, a diagnosis, and perhaps they need to check their work to see if something came loose while they had it apart.
The System Preferences> Displays has a panel to select settings.
You may have to try & see about a reset of System Management Controller http://support.apple.com/kb/HT3964 Or, if reset of NVRAM http://support.apple.com/kb/HT1379 may help. Not sure if these would do anything if there is hardware damage.
Good luck & happy computing!

Can't Bomgar in since upgrade - Screen sharing ... disabled ..unknown display color depth

Since upgrading multiple customer systems to Mountain Lion, I am no longer able to use Screen Sharing in Bomgar. The following message appears: Screen Sharing has been disabled by the customer client. [Uknown display color depth: 0]
The only brief workaround is to tell someone on the other end to manually change the display setting to Scaling instead of Best for built-in-display will allow a one-time access as that setting immediately reverts back to Best for built-in-display. Dumbing it down might make it persist, but that isnt' feasible.
Bomgar support is closed over the weekend. I contacted Apple, and they said that there is no way to make the setting persist. That rep also didn't know of any terminal command that could be used to set the Display Resolution to Scaled either.
If there were a terminal command to set it to Scaled, that would help much because the Command Shell option in Bomgar does work, and I am able to launch a terminal.
I also tried to see if there were any settings I could manipulate in Screen Sharing in OS X, but there were none. I am getting the same result with Screen Sharing enabled or not enabled.
Anyone else experiencing this?

I'm sure you've tried reading https://bbs.archlinux.org/viewtopic.php?id=57084
and http://wiki.cchtml.com/index.php/Configuring
and I'm sure you've done
aticonfig --initial
I had to use https://wiki.archlinux.org/index.php/AT … leshooting, specifically the part about disabling EXAPixmaps to make my card work.
What model is your ATI card? that would help. A LOT of ATI cards were dropped from proprietary support with the Catalyst driver.

Display Colors in Negative

I've had my computer for less than a year. My MacBook suddenly changed in terms of its display colors. Rather than showing colors normally, I'm seeing my entire display in what looks like a photo negative. I'm not sure what to do to fix this problem. I've done all of the updates, and nothing has changed. When I initially restart it appears normal for just a moment, but then it changes to this "negative" display.
Has anyone else had this problem, and how did you fix it?
Thanks!

I tried this option under Universal Access but this did not work for me.
My situation is that it looks like colors are "blurred" for lack of a better word. I can see text as long it is not munged by colors.
I thought it might be a resolution issue but I tried setting under Display in System Preference with no result.
As some others have reported, the MacBook Pro can get very hot under the bottom so I am wondering if the heat messed up the display?
Other ideas to look for? Thanks.

External display - maximum resolution only works in safe mode on MBP

I'm having an issue with an external display connected to a 2012 non-retina MacbookPro 15" i7 running 10.9. Monitor is Dell U2713HM, which has a maximum resolution of 2560x1440, and is connected via a Mini-Dipslayport to Displayport cord.
My setup has been working great for over a year, where while at my office I use the macbook closed in "clamshell mode" with the Dell monitor being the only display in use, running at 2560x1440. However today when I came into my office and connected to the dispay as usual, the resolution on the Dell was noticably scaled. System preferences is showing it running Scaled at 1080p, and when I select Best for Display it stretches to a very wide and distorted resolution. I can hold alt and click the Scaled button to display additional resolutions, however the maximum resolution listed is 1600x1200. Same problem regardless of clamshell, mirror, or extended desktop modes.
I've been trying to track down the problem, and have run though the usual procedures: restart, shutdown, reset PRAM, reset SMC, check cord connections, verify disk, repair disk permissions - all to no avail. However when I boot in safe mode the display runs as it should at 2560x1440 without issue, which lets me know its not a problem with the cord or connectioin, but rather something on the OS / GPU side.
I can't for the life of me figure out what is causing the issue. Considering its been working fine for quite some time, and I've made no unusual changes to the MBP in the past 48 hours when the display was working properly, I'm not really sure where to go from here. Hoping to not have to migrate to a new user or repartion my HDD.
Any suggestions on possible solutions?
Thanks.

I stumbled upon a fix. Still not sure what caused the issue in the first place, but for anyone having the same issue, the display override script contained on the site below seems to have fixed the issue.

Display color problem - asking for a color solution

So I have this serious problem with my Macbook Pro.
Some months ago I suddenly saw green colors in black area's and pink line colors in white areas.
Text on white background was extremely frustrating to read, since it was surrounded with small pink lines and flickering.
Note this was only near max white and max black areas of the screen.
I found out that it was due to a hardware failure, since slightly bending the laptop (!!) would remove the problem
Attaching an external monitor doesn't show the defect, and booting in Windows 7 (bootcamp) still shows the same screen problem.
Searching the web, it appears that it was a NVidia related heat problem, known to my model, but the offer to get it fixed for free by apple (since it was a known issue) had already run out december 2012 (!!). I think my laptop is about 3-4 years old, and the battery pretty much died on me the first year, probably due to heavy usage and the graphic card getting too hot. There are small sweat/corosion marks of where my hand are placed when typing, on the aluminium, due to how hot my laptop got. It sometimes got so hot I couldn't touch the aluminium on the top left corner near the 1-2-Q-W keys.
Fixing my Macbook is too expensive. Just getting someone to look at it to diagnose it (without repairing it), costs a lot in my country, and we have no official apple store, only authorized resellers. I know it's probably the motherboard, because I tried to unscrew the backlid and gently touch certain area's on the motherboard with a pen, while the computer was still running, to find out where the short circuit was. I only started this kind of trying to "self service" it, because I knew how expensive replacing the motherboard would be (if that was even the issue?).
I have multiple times tried to place something up against the sensitive area's on the motherboard, and then screw back the backlid, to put some pressure on it, which at first worked brilliantly and removed the color issue for some weeks, before it started reappearing. I think the heat from the laptop slowly makes the motherboard adapt, and the problem returns. Extremely frustrating indeed.
I hope I can one day afford a Macbook Air, but until then, I don't want to throw more money after my poor macbook (which I pronbably can't sell anyway, like previous mac's I've owned, the day get a new. It's too worn out + battery got only 5min on a full charge).
I think it's wisest to rather save the money for a Macbook Air, and try to survive until then. Therefor I was hoping someone could help me with a temporary solution.
In Windows 7, using the Nvidia Control Panel to apply color management, I was able to adjust the individual color output values, and thereby remove the the screen issue! Maybe the colors are not as good anymore, but it sure beats not getting a headache after 10minutes trying to read an article.
I tried the same thing on the mac, using Preferences>Displays>Color>Calibrate, but this guide is much harder to use to get a decent result (since only the last 2 options really makes a difference, but changes the colors completely, which I can't change by going back to the first color settings since then it just undos the last step I just did. I'm currently writing this with a very blue pale screen.
I also tried to use ColorSync Utility, expecting to enter values manually, but contrary to the articles I read about using ColorSync, I cannot edit the values in the color profile I created (I can only change the ASCII text input fields). Trying to save the profile gives me the error 'The Document "screenbug.icc" could not be saved.'
I tried to look for alternative color calibration software, but most of them required hardware, or expensive full version to unlock the settings I needed (like SuperCal).
I hope some tech savy users out there that can help me, or at least make my life with my macbook less of a pain.
All help is much appreciated!!
PS: I've been a loyal Mac user since always. Few things I've learned is:
1) Don't buy the first version of new hardware. Wait about a month for reviews, to check for issues. I had a problem with an expensive MacPro that had to be replaced, but luckily for free since it was Apple's mistake. Sometimes Apple products also get minor internal changes/fixes without announcements, to help solve reported issues from early buyers.
3) Take care of you Mac, especially so because you can often sell your used Mac's for quite a value the day you want to upgrade. I've sold about 3 Mac's in my lifetime, for quite a gain, though I don't expect this macbook to do as well, if at all. But it's normally something to be cautious about.
3) Don't order custom configurations from the Apple Store, if you can live without it (+ it's usually crazy overprices). I payed extra to get the NVidia GeForce 9600M, and was happy with it for the first couple of years, but is now causing me all the problems I have today + made my Macbook worthless.
Stick with what the default configuration if possible, as other configurations might not have been tested carefully.

Who exactly is your comment "I am asking you to fix this problem soon" directed at?
Remember that you are posting on a user to user forum so nobody can really help you. If you want to give feedback to Apple, then contact them directly at http://www.apple.com/feedback.
Also, if you have an iPhone 3G and iOS 4.2.1 is the latest software that you can install on your phone, then there is absolutely nothing that anyone can do to fix the problem if you want to install Skype that requires iOS 4.3 - what do you think anyone can magically do?
iPhone 3G is a very old phone now and if you want to install Skype on your phone, then you need to go out and buy a new iPhone - either a 4s or a 5. Nothing more to it. Buy a new phone.

Bridge displays color images as b&w

I assume this has something to do with settings in Bridge CS4, my platform is MacBook Pro OS 6.8.10.
This question might confuse some people. To beging with, I do shoot my images in RAW files, I even have Bridge convert them to DNG files.
Upon download the images are displayed in color as they should be for RAW files. After editing images in Camera RAW, I convert most all images to sRGB. When some of those edited images come back to Bridge, they might be presented in B&W, though no color is lost to the file upon displaying in Photoshop, and I did not edit the file to be a B&W image. I have DNG, Canon RAW, Tif and Jpeg files, and most of these are displayed in color, but some are not, and I have not figured out the missing link just yet. So to be clear, I have Jpeg color images, displaying as b&w images, but they are color images. Only b&w images should be displayed as b&w.
This problems started once I learned I could edit one image in photoshop out of a series of images, then after editing, i could bring the single photo file back to bridge, and then copy/paste image settings onto a groups of images in Bridge, and all those images would then have the same adjustments made to them as a batch edit adjustment.
But now sometimes I get a B&W display on some images even when I do not apply a Bridge settings edits, and when I never edited the image for a B&W display. I has to a setting somewhere in Bridge, and I just have not figured it out yet.
Thanks in advance for all suggestions:

Yammer asked a pertinent question that remains unanswered—is that “settings” badge (small lines-triangles-in-a-circle) shown on the B/W image thumbnails (at least). If you’re not sure, then include a screenshot of a few Bridge thumbnails where some are color and some are B/W, using the little camera icon on the web version of the forum messages.
And the answer is NO!. I only have those showing up associated with the .DNG files (Camera RAW)
Another similar question would be if you see a B/W thumbnail in Bridge, try doing a right-click (or whatever the Mac equivalent is) and choose Open in Camera Raw. Is the image in B/W or color in Camera Raw.
A <Control Click> (on MAC), opens the .jpeg file in b&w, as shown in the thumbnail.
Can you upload three versions of one of the images that display as B/W: the original PSD/raw/TIF file, a normal Save As JPG that is in color, and a Save For Web JPG that is B/W? Use something like http://www.dropbox.com/ and post a public download link to the images, here.
NO, I thought I explained that real well. Only the .jpeg file that was saved through the "Save for Web" processing ( that is, the a jpeg the goes through greater compression to reduce image file size for web display), is the image file process that produces the b&w thumbnail in Bridge ONLY. All opened images, of various file formats (ie: DNG, Psd, Tif, Jpeg, & Jpeg for Web), all present Color presentations (for editing in Photoshop, and or in display browsers). It is only the thumbnail of that particular jpeg formatting processing for Web Images that produces the b&w image "THUMBNAIL" in Bridge.
When you Save As JPG or For Web, are you ever overwriting the original image with a new one or do you always save the PS-edited image with a new name?
No, never. I leave my RAW files, as RAW originals, and work on newly names images files.
A theory about what is happening is that Bridge uses Camera Raw to generate its thumbnails, and the images that are B/W have some embedded Camera Raw setting, perhaps pasted from a different filetype, that makes CR think the image should be rendered as B/W, but when you open the images on Photoshop, you are opening them directly, without using the Camera Raw plug-in, so any embedded settings are ignored, and the image displays in its original state without the settings having been applied.
It makes since, (what you are saying), and it certainly does respond in that fashion. Your suggestion to open Ctrl Click, or Right Click to open the thumbnail in Camera RAW, was an interesting test, and the response was to open the previously save color image with a b&w thumbnail, into Camera RAW as a b&w image. So Camera RAW is responding to what is in the xmp settings that describes this images thumbnail to be displayed b&w. It is weird that a browser does not.
As to what is in the window selections for the "Save for Web" editing windows, Presets for jpeg are :
Progressive
Optimize
Embed Color Profile
And I use Embed Color Profile.
Even the Preview button at the bottom of the window, shows the color image as displaying color.
I vaguely remember about a year ago doing some CS 4 Photoshop and Bridge web tutorials from an unnamed tutoring website and guy named D_k_ . It is his fault. Just kidding, I actually enjoy those tutorial.
**** Okay, this is perhaps originating from Camera RAW presets, where you can apply previously made settings to other images and then saved them as Presets. Though I don't have this checked in Camera RAW ( still something goofy is going on there), I did find that in Bridge I can reset the individual "saved for Web" image thumbnail back to the the color image by :
Right Click (Ctrl Click, MAC) on the thumbnail
menu down to the "Development Settings" and select :
"Previous Conversion", and this presents the color thumbnail.
I have now tested all the Camera RAW settings in Camera RAW, by opening an image in each one of these :
Image Settings
Camera RAW Defaults
Previous Conversion
Custom Settings
and then reducing image file size, and saving for the web, while changing file name, and each and every one of these Settings produces a Sepia Toned thumbnail. I found out the images were a subtle Sepia Toned image by enlarging the Bridge Thumbnails bigger for a better view. So I can correct the thumbnail after it has been created, but so far, I can't get the thumbnail to be correct on first creation of the web saved jpeg image file. Regular jpeg image file thumbnails save correctly.

[Solved] Can't get external monitor to display correct resolution

I have a laptop with 1280x800 resolution, I hooked up a spare monitor we had sitting around that has a native resolution of 1280x1024 to my laptop. When I hook it up the external monitor displays a resolution of 1024x768. I use KDE 4.5, so I tried to change the resolution for the external monitor in System Settings but 1024x768 is the highest resolution listed.
I've tried messing around with xrandr through the command line (somewhat anyway) but I'm at a loss in trying to get the external monitor to display its native resolution. I'd like to get the external monitor to possibly replace my laptop monitor as it would add another 224 vertical pixels. Anyone have any ideas?
Last edited by herrvideman (2010-08-31 02:17:48)

You had said the native resolution is 1280x1024 -- I therefore assume this is an LCD monitor.
I would not generally expect LCDs to flicker. At what vertical frequency are you driving the display? Most LCDs operate at 60Hz. This is regardless of the local power line frequency or television standard.
Many CRT monitors are driven at 75 Hz to keep them from flickering or from "beating" with ambient lighting that is flickering at the local power line frequency (50 or 60 Hz). Again, this is not the correct thing to do with LCDs.
Bottom Line: Make sure your vertical frame rate is 60 Hz.

HOWTO: Can't display any resolution above 640x480, or other crappy res

I've been working on this problem for half the day, and finally figured it out after many hours of frustration. During my search for a solution, I've seen other people who had the same problem but was never resolved on these forums. Rather than bumping an old post, I've decided to create this "howto" hoping that someone experiencing the same problem may find this post.
The problem is that Xorg refuses to display any resolution above the minimum, which is 640x480. This was the resolution in my case, and searching around, it's the resolution many other people experienced, as well, who experienced this same problem.
Check your Xorg log in /var/log/Xorg.0.log . Search for "No valid modes for". If you see something like this, then you are experiencing the same problem I had:
(WW) NVIDIA(0): No valid modes for "1680x1050"; removing.
(WW) NVIDIA(0): No valid modes for "1024x768"; removing.
(WW) NVIDIA(0): No valid modes for "800x600"; removing.
(WW) NVIDIA(0): No valid modes for "640x480"; removing.
(WW) NVIDIA(0):
(WW) NVIDIA(0): Unable to validate any modes; falling back to the default mode
(WW) NVIDIA(0): "nvidia-auto-select".
(WW) NVIDIA(0):
In my case, this only occurred when I was using the nvidia driver (it went away when I just used nv).
Ok, so here's how to solve the problem...
Has your monitor worked with your machine before?
If your monitor, graphics card, etc. has worked with your machine and xorg file in the past, and it suddenly stopped working without anything changing, then try rebooting your monitor. (I'm serious!) Log out, turn off your monitor, and unplug it for several seconds. Plug it back in and log back in. This ended up solving my problem, after I edited my xorg file (see below)... but just editing the xorg file and rebooting X wasn't enough
If monitor rebooting didn't help, or you've never got your monitor/graphics card/xorg.conf working together in the past
If this is the case, your xorg.conf probably isn't configured correctly. Assuming you already have a xorg.conf file (this post is NOT meant to replace the other howto's on how to configure your xorg file), here's the basic rundown of what your xorg file should have...
Make sure that you have the "Modes" set in your Display subsection of Screen. Here's what my Screen section looks like:
Section "Screen"
Identifier "Screen0"
Device "Card0"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Depth 16
Modes "1680x1050" "1024x768" "800x600" "640x480"
EndSubSection
SubSection "Display"
Depth 24
Modes "1680x1050" "1024x768" "800x600" "640x480"
EndSubSection
EndSection
(the line(s) in bold are the ones you need to make sure you have)
If this still doesn't work, make sure that you have the appropriate Modeline set. I chose to make a Modes section like this:
Section "Modes"
Identifier "16:10"
Modeline "1680x1050 (GTF)" 154.20 1680 1712 2296 2328 1050 1071 1081 1103
EndSection
Your Modeline probably won't look like mine. Hopefully, you know the specs of your monitor (or can look them up). You can use this tool to generate the Modeline for you:
http://xtiming.sourceforge.net/cgi-bin/xtiming.pl
Finally, make sure that the Monitor section includes your HorizSync and VertRefresh options. These are values specific to your monitor (again, you'll need to look up your monitor's specs)
Here's my Monitor section
Section "Monitor"
Identifier "Generic Monitor"
HorizSync 30-83
VertRefresh 60
Option "DPMS"
UseModes "16:10"
EndSection
Log out and log back in. If the problem persists, reboot your monitor as described above.
I hope this post will help someone, someday!

Hi-
You can plug a DVI-I dual link female into the DVI-I single male on a graphics card.
From the outside, the male has all the holes for all the pins on the DVI dual, there are just no wires attached to the center group of the DVI single male.
The Radeon 9800 is a DVI-I single link card. There is no getting around it.
The maximum supported digital resolution for a Radeon 9800 is 1920x1200:

U430 dull display colors

I got a new u430 touch. Everything seems great except the display. I get the feeling that the colors are washed out and no black levels. Tried a simple test http://www.lagom.nl/lcd-test/black.php
Unable to see the first 5 black squares. Poor contrast. These are visible in my 5 yr old dell vostro. Is a dull display and lack of vivid colors on u430 normal? Pretty disappointed since display colors are very important for me. Surprised how even a latest display is not vivid. Can someone advise what my options are? Does only U430 suffer from this problem? Are there any calibrations that can fix this to some extent? Are there any lenovo laptops with good display under $600

Did you find a solution? I've got mine rigged to a really old monitor - shamefully the display on that is miles better than the U430 - feels totally washed out!!
