Color Depth choices removed?

Just installed Snow Leopard (surprise!) and am having an issue with the display.
Some older games which ran flawlessly under 10.5.x are now no longer working. Just a black screen when it launches, with full audio and keyboard interaction possible.
I suspect that 10.6 is not allowing the game to change the color depth to 256 color mode. I noticed that "Thousands" is no longer an option, either.
How can we get 256 color mode back?

Hello jonashly,
What make / model computer are you using?
What operating system?
Sounds like a possible video card driver issue, have you tried uninstalling and reinstalling new drivers?

Color Depth Choices Removed...Any other way to change?

SL removed color depth choices in displays. We use display link adapters (USB video cards) for extra external monitors (email/web etc) and setting the display to thousands increased performance dramatically. Now we are stuck at millions...
Anybody have some command line fu to change the display color depth?

AMD FireGL GPU + Creative Cloud app = Color Depth & other Issues

Hello, I am writing this post to help anyone who may have ran into the same issues I am seeing with my AMD FireGL graphics adapter when using the Adobe Creative Cloud app on a windows 7 PC.
I ran into a problem installing and setting up the Creative Cloud app on my new workstation that has an AMD FireGL graphics processor.
First off, the system is new (dell precision m4800, with an AMD FireGL V M5100 GPU), and has all the most current drivers and updates available.. that is to say, this is not a hardware issue.
The system operates just fine outside of the Creative Cloud app, but when I installed and attempted to login to Creative Cloud for access to download Illustrator, etc., the Creative Cloud app would open up and then only display a blank white page. No graphics, no data, just white.
When I got stuck at this point I called Adobe support and spoke to a rep who had seen the issue before. The rep worked around the blank white page in CC by loading the windows device manager and manually disabling the AMD FireGL GPU device to re-install and login to the Creative Cloud app.   This temporarily forced windows to use the default/dummy VGA graphics driver supplied with windows.   With windows using the dummy 256-color vga driver we were able to get the creative cloud app running and get me logged in to install my design software. HOORAY!--or so I thought....
At this point I assumed the issue was resolved, but I found that there was a new issue popping up every time I rebooted my system. Windows would load and log me in using the 32bit color depth setting, but as soon as the Adobe Creative Cloud app started up, my color mode would switch to 256 colors... D`oh!
Obviously I don't want to run at only 256 colors, and neither should you! Adobe, why does my color depth change to 256 colors every time the Creative Cloud app is loaded?
If you want to temporarily reset the color depth to 32bit, you can go to Control Panel -> Display -> Adjust Resolution -> Advanced Settings -> Monitor Tab -> & select "True Color (32bit)" from the Colors drop-down menu. Using this method will allow Adobe Creative Cloud app to continue running 24/7, however this is only a temporary fix, which will need to be applied every time the system is rebooted, or any time a user logs off then back in.. Frankly, its a bit of a PITA, so why bother?
The permanent fix is simple.. go to Start -> & do a Search for "msconfig".   Once found, run the msconfig utility and switch to the "Startup" tab, where you will be presented with a list of boot time startup items. Find the one labeled "Adobe Creative Cloud" and disable it by removing the check mark from the corresponding check box.   Then click OK. You will be warned that a restart may be required.. go ahead and re-start.   This time, when the system boots, Adobe Creative Cloud will not load, and your color depth will remain at 32bit. YAY!
If need be you can always load up Creative Cloud manually from the start menu if you need it, but it will knock your color depth back to 256 colors. Thus far i have had zero issues using adobe photoshop or illustrator without first loading the Creative Cloud app, so it isn't required. If i need updates or need to access other features within the Creative Cloud app i can, but it doesnt need to run 24/7 to use other adobe apps.
The short explanation is that Adobe is failing to fully and properly support the AMD FireGL graphics platform. The adobe rep i spoke to essentially said the same thing, but made certain to blame the graphics device and not adobe software--sure thing boss.   The truth is that the FireGL and its varients have been on the market as long or longer than the nvidia products that are supported fully by adobe.
It is clear that Adobe has made a choice not to fully support AMD Workstation graphics (FireGL) since not only is the Creative Cloud app broken and causing problems, but also no graphics acceleration features work in any of my installed adobe apps.. I basically get a message saying "please us a supported graphics processor". Seriously, how is FireGL not "Supported"?
I am not an AMD or FireGL fanboy.. Frankly I cant stand AMD graphics adapters and I genuinely prefer nVidia on my personal systems. At home, my 5 year old $100 nVidia gaming card is fully supported in all the adobe apps..
At work, however, I have no choice what hardware is provided to me and this lack of FireGL support has negatively impacted my productivity more than once. Admittedly, nvidia has much more market share than AMD in the workstation graphics realm, but that does not mean adobe should just ignore AMD completely!
Hopefully this post will shed some light on issues with Adobe Creative Cloud app and FireGL graphics cards that others may be experiencing.
Good Luck!

Minor correction... I called my GPU the FireGL, which is the old market name.. The current, proper market name is FirePro.. same line, just new branding after AMD purchased ATI.

How to fix gray background on images without checking "retain color depth"

I have a cover page on my report where the user can insert a logo image. The problem is that if the logo image has a white background it will turn the white background gray. I have figured out how to resolve this by checking "retain original image color depth.u201D The problem with this is that all the images in my report are larger so the report pdf file size goes from 3mb to 30mb. Is there a way to make the logo image appear as normal without having to check the retain color depth? I have tried adjusting the image in photoshop several different ways but havenu2019t figured it out yet.

That is exactly why the option is there. And why it is unchecked. Most people prefer to have smaller report size. The choice is small reports with the option unchecked and the loss of picture quality, or bigger reports with the option checked, retaining the picture quality. THis a by design and is not consiered to be a "bug". If you post the issue into the [idea place|https://ideas.sap.com/community/products_and_solutions/crystalreports] perhaps it will get picked up as an enhancement, but that it the best I can suggest.

Changing Color Depth

I need to change the color depth of an external monitor, but it seems this has been removed from 10.6! How can I change the color depth of an external monitor? Thanks!

You can improve the framerate only if your application is fillrate limited, if it is polygon limited you will see no difference.
But yes often you get increased framerates, but beware that using 16 bit colours will on NVidia mean you also use 16 bit Z-Buffer, which can lead to annoying rendering artifacts.
You have two ways to set the colours:
1) Change desktop colours to whatever you wanna use.
2) Use exclusive fullscreen mode, and set colours.
How about rewarding me some duke dollars for that answer? :)

Adobe Reader changes system color depth settings to 256 colors

I am writing here for a friend who has a Windows 7 system and Adobe Reader in version 9.4
Each time he opens Adobe Reader the system settings for color depth are changed to 256 colors, which makes PDF documents barely readable. It is possible to change the color depth back to normal in the system settings, but each restart of Adobe Reader switches the system again to 256 colors.
Does anyone here have a clue how to stop this behaviour of Adobe Reader?
My friend has tried to remove Adobe Reader and reinstall it, but the problem remains.
Since I am a Mac user my Windows abilities are very limited and I am very grateful for any help.
Thanks a lot,
macvet

Could be a hardware malfunction. Maybe you should take that MacBook to an Apple store and have it checked out.

Unsupported Color Depth

I have a Gateway 500SE PC, Home XP, Nikon View 6.0.0, Photoshop Elements 1.01. I have a Nikon D100 camera. When I import a Nef uncompressed file into Elements it gives me an error box...Unsupported Color Depth. I must change these pictures to a supported color depth. This takes too much time to change every picture in a folder when you want to make a contact sheet What is this and how do I fix it?
Thank You Very much,
Sandy

That's because the nikon nef plugin is opening the files in 16 bits/channel and pse 1 (photoshop elements 1) doesn't support 16 bits/channel documents, thus that's the reason for the message about unsupported
color depth (bit depth and not the color profile). Pse 1 can only supported images up to 8 bits/channel so it has to convert the 16 bits/ channel images to 8 bits/channel.
(photoshop elements 2 can turn that message off and automatically convert the files to 8 bits/channel, but pse 1 doesn't have that option. And in pse 2 with the contact sheet II it automatically
converts the the files regardless whereas pse 1 does not)
You have a couple of choices:
1. Just press the Y or Enter key when the message appears
2. Print a contact sheet from Nikon View
3. Either copy and resize the images with the view browser (Tools>Copy and resize as Jpeg file(s)
or use the Nikon Capture Editor under Tools>Batch to convert the folder to another format like tiff 8 bits/channel
4. You might try a program called IrfanView for contact sheets.

If you use the batch from pse 1 then you have twice as many dialogs to deal with

Remote desktop from Win 7 to Win server 2003 only allows 16 bit color depth. How to increase to at least 24 bit?

Hi! I'd like to RDP in to a Win server 2003 computer from my new Windows 7 (x64) computer. There's no problem to connect but the connection only allows me to use 16 bit color depth on the Windows server 2003 client. The program I want to use on this computer requires at least 24 bit to run.
I've googled around and tried it all:
-setting the color depth to 4 or 5 through regedit (on both computers)
-creating a Group Policy object-snap in through mmc
-reading endless of forums but no one has had the same issue as I
My question. If all the ordinary solutions isn't working what could the issue then be? My only suspision at this point is the the RDP-client on Win server isn't working properly. The Windows Server 2003 client is fully updated machine and it should have the RDP 5.2-version installed but I can only find 5.1. Could this be the issue? That it needs to be 5.2 to properly communicate with a win7(x64)? If so, how can I upgrade solely the RDP-client since it seems not to have followed with the Automatic Update as it should?
All answers and feedback are very much appreciated!
Many thanks
Frank

Hello Frank,
Thanks for your feedback and the test.
I still recommend you to check the local group policy setting “Limit maximum color depth” on the Terminal Server side. Based on your description of Group Policy Object Editor, I suspect the loss of Terminal Services folder is caused by system.adm file not loaded successfully. Please try to fix it via the following steps:
1.     Open Group Policy Object Editor (run “gpedit.msc”) on the terminal server.
2.     Expand Computer Configuration \ Administrative Templates
3.     Right click Administrative Templates folder and select Add/Remove Templates, if system is not listed in the panel, go to Step 4; If it is, remove it and go to Step 4.
4.     Click Add button.
5.     In the next phase, it is Windows\inf folder, if it is not, please navigate to the folder. Select system.adm file and click Open.
6.     Check if the Terminal Services folder appears under Windows Components now.
Thanks for your cooperation and we’re looking forwards to the result. Thanks.
Regards,

Font Smoothing/Clear Type disabled on RDP Session, color depth low

Hello
One of our customers has a new laptop Asus G771JM-T7021H with Windows 8.1 on it. The graphics, font etc. is good as long as he works locally. When he connects to the terminal server (2012R2) via RDP, the resolution and font is hardly readable. It seems that
the clear type is disabled, everything is blurry and pixelated. The color depth seems to be very low. We've checked the RDP-configuration and the graphic card driver but couldn't find anything wrong.
Any ideas?

Does duplicating layers from an 8-bit PSD reduce the color depth of a new 16-bit edit?

I have been using several versions of Photoshop over the years starting with CS3, then CS6, and finally CC. Through 2012, all my RAW files were converted using 16-bit color depth in ACR. However, in examining my files recently, I noticed all were in 8-bit color-depth, which likely happened once I upgraded to CS6 and ACR left 8-bit as the default. As such, I now have hundreds of images that I wanted to edit in 16-bits that have been converted to 8-bit starting with my ACR export. The files are all RAWs from cameras like the Canon 5D, 5D Mark III, Olympus OMD EM5, and Sony RX100.
I have 8-bit PSDs of my edits of these files which contains multiple layers. I use features from the Nik and Topaz collections for noise reduction, contrast enhancement, black and white conversion, and sharpening. I also use layered Photoshop features like Selective Color. I want to know if I can simply duplicate the layers from the 8-bit PSD files onto a new 16-bit RAW converted background layer rather than re-edit each and every file. There would be no change in the crop of other reasons why the layers would not match up, but I am concerned that duplicating those layers might throw away the benefit of moving to 16-bit since they were created in an 8-bit color-depth.
As a test, I looked at a few files where I had pushed the shadows and colors to an extent and duplicated the layers from an 8-bit conversion to a 16-bit conversion and could see no difference. I am not sure if this is because Photoshop has become very good at reducing color-depth without a perceptible difference or if I am throwing away information in moving the layers.
I work off of a fairly modern computer and a top-end Eizo CG276 self-calibrating monitor and good video card. I am extremely sensitive to color and shade changes as well.
Thanks for any help, I am a bit stressed at the thought of re-editing hundreds of files from step 1, but it is important to me that I not throw away color information and it is better I start re-editing now rather than years from now.

While raw file contain a 8Bit jpeg previews image in some color space. The RAW sensor data is not a color image and has no color space and the bit dept of pixels depend on the manufacturing. Most sensor produce one value for each pixel 10 to 14 bit seems to be common. Sensors only measure the light intensity not color. If front of each pixel sensor is a color filter which lets Red or Green or Blue light be measured for intensity.
A RAW converter can convert your sensors RAW data into a color RGB image in any color work-space in 8 or 16 bit color depth. No Adobe update went around and scanning your computer looking for 16bit color depth images and convert all of them to 8bit color. Your ACR workflow settings may have been change from 16 bit color to 8 bit color by you or set to 8bit by some update or script used. So you current ACR work-flow setting may be converint tou raw datya into 8bit RGB images. As long as you have you raw files you can reprocess these to produce 16Bit color RGB Image by makinf the proper ACR work-flow settings. You can also change your 8bit image to 16 bit image mode. However this will not recover any color quality lost or posterization that has set in.. It will give you a bit more latitude using Photoshop filters which may help you not get banding posterization.

Display-Color-Depth

Hi there.
After an application-crash (After Effects) and cold restart my monitor-color-depth suddenly switched from millions of colors to maybe several hundreds of colors. I've tried cleaning the caches, throwing out preferences-files (out of library) and also resetting the color-depth by using third-party-applications. Still not working. I suppose it's some kind of problem in one of the preferences-files in the library, but I don't know which one.
The "About This Mac" section shows that the monitor would show some "Millios Of Colors".
As I can not work like this I made a new user-account. In the new user-account everything runs smoothly but for sure I would like to use my old user-account with all my settings and preferences instead of switching to a total blank one that I have to modify again to fit my needs. Does anyone have an idea what could be wrong or how to succesfully force the display to display millions-of-colors again?
When I log into my old user-account the display first shows normally, then switches to "hundreds-of-colors" after a split-second. Is there any way to slow down this process and monitor which preference-file the computer is loading in exactly this moment?
Also weird: when I connect to my old user account via remote access / screensharing (vnc://...) then the display looks normal from the remote computer.
Any ideas would be welcome. Don't know what else to do...
Cheers, Aeiou

What does it say if you go to About This Mac -> More Info -> Graphics & Displays -> Pixel Depth
1: Try resetting the PRAM.
2: Go to System Preferences -> Displays -> Color -> Select another profile or calibrate
3: Go to System Preferences -> Universal Access -> Slide the Contrast bar all the way to the left
Might end up just being a plist to snag though.

W500 - switches to 16-bit color depth after disconnecting LCD TV

Hi guys,
My W500 always changes the screen color depth to 16-bit when I select "Notebook only (factory default)" on Fn+F7 menu, after watching movies on LCD TV. It happens both on Display Port and VGA connector. I have set "separate displays" (no desktop cloning). I remember having the same issue with old T61p. How to prevent that from happening?
cheers,
Mika

Sun JDS Color Depth

I installed Solaris 10 06/11 on an x86 PC
I found that XSun drivers works well for my video and display
but when login to Sun JDS the Colors are limited.
all descussions I saw in the forum are about Display Resolution , But I think that it is a Color Depth Problem
Please Can any one tell me how to change the color depth for Sun JDS to be 24 bits only ?
Thanks

You typically use the 'fbconfig' command to change colour depth. Check the man page.

Color depth

What is color depth of macbook and is it possible to change it? from 32 to 16bit. if so does it improve system performance?

Hi dog,
apple macbook (at system preference) doesn't offer that 16 - 24 - 32 bit depth, but it offer 256 - thousands - millions color.
I think it might make the gpu task easier, but I doubt you will notice the improvement.
Better get more memory to improve your overall system and the gpu shared memory as well.
Good Luck.

Will mountain lion supports a 10 bits color depth?

Just wondering if and when it will, and how much it affects color accuracy in photography comparing to chain that supports a full 10 bits per channel color depth.
Thanks in advance for your answer.

Great machines but I liked OS X being different to IOS, now the line between both is far to blurred and seeing the same thing on every machine almost is not what I personally want, this is not innovation in my mind just assimilation, time to look for something else why my iMac still has some value.
Then please be realistic. The announcement just came out and people are already arguing over the cost or if it will be free. That will be well down the track. Just get on with using either Lion or Snow Leopard, whatever you prefer and worry about ML when it is released!
