With my AMD card, there is a specific setting in the graphics card driver to enable 10 bit output.  Once enabled, you need to reboot and Windows automatically disables Aero.  There is no need to disable Aero manually.  This is also true of other video/graphics changes which are incompatible with Aero, which is that Windows disables Aero automatically. I didn't see where you mentioned changing a setting in your display driver to enable 10 bit.  If you haven't tried that then look at all the settings in the display driver for your card.  And I just noticed Chris Cox mentioned this already with the "Deep Color" setting. ...

Paige, You apparently didn't go to the link provided above.  It's the Camera Raw Preferences from the Edit menu.  No rebooting necessary, no unplugging, and not a calibration issue.  Here is the dialog box: Just make sure you have jpeg and tiff support disabled as shown. ... View more

Georg, The hardware may technically have the ability to handle 10 bits, but unless specific support has been added to the display driver it will not work.  Unless there is something new in the standard (non Quadro) Nvidia drivers, you cannot get 10 bit with a GeForce based card.  Another way to put it is that a Display Port interface may be necessary for 10 bit, but it is not sufficient.  Ask Zotac to send you the screen shots of the display driver settings to enable 10 bit and see what kind of answer you get. ...

I can confirm that 10 bit color works fine in PS 12.0.4, just like it did in 12.0.3, so "NEC271" the problem is on your end.  I have an ATI FirePro V4800 with the driver info below: Note that if any 'element' of the taskbar (pop up, jump list, whatever) appears over the Photoshop window, the banding will appear until that element is no longer over the PS window.  Also, if you hold down the left mouse button in certain areas within PS (the top bar of any of Photoshop's child windows {e.g. the Navigator window} qualify) the banding will appear.  I assume it is possible for other scenarios to also break the 10 bit color pipeline. Since you said you had 10 bit working before, I assume you already have this set: I have Win 7 64 bit, in the event that makes any difference. ... View more

"gator soup", You've got two sRGB users here (in the recent posts) already who appear to very technically savvy about using sRGB.  I don't see your posts contributing to the discussion at hand. P.S.  For myself I have zero interest in the "sRGB is the holy grail" mentality that guys like Greg Ballard are preaching because I know just how limited sRGB is versus what the human eye can see.  Regardless of the widespread use of sRGB, simply continually repeating that using sRGB is the answer just acts to help hold PC color technology back.  One goal should be a much wider gamut across the board for all users, and another should be sure fire ways to avoid the issues that people are describing in this thread. ...

Connie, Indeed there was information earlier in the thread about your color management settings, including in your original post.  (At this point one problem is there's reams of info in this thread.)  One thing I quickly noted is that you've gone from "Relative Colorimetric" rendering to "Perceptual".  Do you know if this change made any substantial difference? I also note that on the Advanced tab you're using "WCS profile for sRGB viewing conditions" instead of "WCS profile for ICC viewing conditions".  This is one I'm in the dark on but my instinct was that with any custom calibration the ICC choice would be the way to go.  Now that you've thrown in another curve ball with turning off the Windows Color System service I'm not sure this even matters at all.     Have you received any knowledgeable help on this setting that panned out? Also, if you're sticking with sRGB why not have your Dell's mode set to sRGB instead of Adobe RGB?  Did I see that right in the picture above?  (I'm trying to go Adobe RGB all the way through except when I share images with others for use on other PCs, so I'm using the U3011's Adobe RGB mode.) ...

Connie, In Windows 7, could post screenshots of the 3 tabs of your Color Managment dialog box? Perhaps with the drop down of all device profiles showing such as below?  I know you probaly can't get all of them showing at one time, but perhaps your monitor related profiles are grouped together. Forgive me if you've already been through this exercise, but it's really not obvious how this is set up in Windows 7.  And it's apparently not at all obvious how Adobe is using whatever color profiles are available either.  I'm hoping I can learn a bit more from your ordeal so I don't repeat it. Johnny, Keep us posted on anything you find.  I suggest reading through the reviews at  http://www.tftcentral.co.uk/  (both the wide gamut monitors as well as the calibration tools) if you haven't already.  Their info is why I plan to go with the Lacie solution. "gator soup", How about giving the "convert to sRGB" mantra a rest?  Johnny is obviously already fully up to speed there and I'll bet money that Connie is as well. ... View more

Johnnysks76, Your original pics didn't show as big a difference as what Connie had.  It even looked like there may have only been mostly a brightness difference.  When you're optimizing photos of course you don't want even the small change, and since you've bought a wide gamut montior you're interested in quality. I would guess that the standardization on sRGB years ago is the main cause of the problem.  If you're properly calibrated and color managed things should look the same on wide gamut or limited gamut monitors.  Or if you set your wide gamut monitor to do the limited gamut of sRGB you may be okay with and without color management in software. I have my Dell set to Adobe RGB mode and I've calibrated using a Spyder 2 Pro but with the ColorEyes Display Pro software.  I do plan to upgrade to the Lacie software and X-Rite hardware kit, but I'm not sure that either my calibration method or using the Adobe RGB mode of these is causing the large shifts I see, or in the large differences between some of the thumbnails vs. the full previews in Bridge.  It looks to be a more substantial change to me, similar to what Connie showed. Are you using the sRGB mode on your Dell? Update: Your last post came in after the above text.  Those pics are interesting. Message was edited by: Chris_BC_1 ... View more

I first suggest ignoring "gator soup" and continuing your comparison of monitors, and add in some different settings in Bridge. Of course everyone should always be using color management and ALL programs (Perhaps things like Notepad are exceptions, but not anything that displays graphics.) should be capable of color managing, but your experiments between limited monitors and your new wide gamut montior could be quite valuable, and this may be the the right thread.  (If you're turning off color management only to try and duplicate the color shift in Adobe Bridge you see that may be valid.  Gator soup appears to assume you don't know that turning off color management will change the colors you see on a wide gamut monitor.) I have a Dell U3011 and can see the color shifting behavior in the thumbnails in Bridge as well as the full size preview in Bridge, but I don't think this is happening for me on pure jpegs.  I have found a couple of different ways to see the colors shifting in .CR2 files from a Canon 7D.  One is to change the option for thumbnail and preview generation near the upper right of the Bridge window.  It's in the lower toolbar just above the main preview window when you are in "ESSENTIALS" view.  (It's still there in the other views in the same general location.)  When I toggle from using the embeded image to generating a high quality preview, the thumbnails will go from dull to oversaturated.  The large preview appears to be about right in some cases and thus does not match the thumbnail.  In some cases though I'm seeing colors that are dull. The other way to see the changes is by changing the camera raw defaults, and then reverting back to them.  In my case both issues I'm talking about are Adobe specific.  To be relevant to Connie's original issue, and to what I'm trying to work on, I think you will need to be looking at the differences in the Adobe software.  I think there may be an issue which is unknown to Connie and others or at least not fully understood, and/or there could an unintended "feature" in Adobe's color management that is causing problems. I look forward to your feedback based on changing preview settings and perhaps other settings in Bridge and comparing the differences on your limited gamut montiors vs. your new Dell wide gamut. ...

Connie, Interesting problem.  I'm sorry you've had so much trouble.  I also have a Spyder 2 Pro that I used on a Dell 2405FPW, a couple years ago under Windows XP and recently under Windows 7.  I also use Photoshop and Bridge (often using the Adobe RGB color space) but didn't experience any problems such as yours. I recently got a wide gamut Dell U3011 and hooked it up before uninstalling or trying to disable the Spyder's profile change that occurs every time Windows is booted.  I had gone to TFT Central and installed the Adobe RGB profile they created for a Dell U3011, and on the next boot the Spyder software spit out an error message about the profile having too much information.  (I have since uninstalled the Spyder software.) Perhaps that doesn't tell you much, but if it turns out that your issue is related to the Spyder calibration, the video card, an incompatibility between the video card and the Spyder software, with Windows and the Spyder, etc., or some other non Photoshop problem, you owe Adobe a big apology. Please update us all when you have more info. ... View more

My apologies if I stray slightly off topic.  I feel for you guys and agree with your expectations that the company that is supposed to be the leader for photo/video pros should be ahead, not behind. Since a couple of you sound like you are pros I thought I would ask if you have any counterparts working in Windows who are using 10 bit color on their displays.  I've started a separate thead to ask current 10 bit using about their hardware.  Please pass the word along and/or provide your own feedback.  Thanks. ...

Chris, I was hoping for some new updates.  Any info on 10 bpp support on cards other than the Quadro or FirePro workstations cards would be greatly appreciated.  Even if it's just links to other sites that you feel might have good info. I just upgraded from CS3 to CS5, and I finally sprung for a Dell 30" monitor, in this case the 10 bpp capable U3011.  I have an Nvidia 8600 GT based card from XFX right now so I'm looking for an upgrade.  The FirePro V4800 is available for about $160 and indicates full 10 bit support all the way through.  ATI also provides step by step instructions showing how to make it work in their driver and then in CS5. My concern is that the V4800 workstation card may not be the highest performance option all the way around for me to use.  (I don't do gaming right now but would like to keep that possibility open.)  Any info on performance would also be appreciated.  Even if in informal tests you've done at Adobe.  ATI lists this card as for entry level on Photoshop even though it has 1GB of GDDR5, and as part of their description they mention smaller files and lower resolutions.  (The "mid level" FirePro V5800 has the same RAM {and standards support, e.g. Open GL 3.2} but 800 stream processors instead of 400, and it's over twice the cost at around $400 and that's a good bit more than what I want to pay.) I'm going to be editing RAW files from an EOS 7D (as well as older ones from an EOS 40D) and my thought is that they would qualify as large.  I can edit them now with the 8600 GT card but I did notice a big slowdown in CS5's response when I went from 1920x1200 to the 2560x1600 of the Dell U3011.  My goal is to get the performance above that I had before and at the same time get the 10 bpp display capability. Feel free to put whatever disclaimers you want on any info you can provide, but please let me know what you think of the V4800, and also what other options in the non-workstation card you have "confirmed" to work.  Also note that preliminary info on stuff coming is fine as well. Specifics would be great. I'm already in contact with XFX and so far have received contradictory info.  The first tech said only a workstation card would do 10 bpp, but then a 2nd tech came back and said their Radeon cards with DisplayPort would do it as well.  I replied back to request a confirmation (asking for some specs and/or a technical document) but have yet to get a response. Thanks in advance for your help, and thanks to Adobe for pushing the envelope to bring us better performance. ... View more
