The Late 2015 Retina iMac includes the first wide gamut display that Apple has made for a Mac, able to reproduce colors well outside the sRGB color gamut. At that price you get a quad-core 2.3-GHz Core i7 processor, 8GB of RAM, 256GB of flash memory and Nvidia GeForce GT 650M graphics. The MacBook Pro with Retina Display starts at 2,199. 2) Right-click on the app you want to open in low resolution mode from now on, and click on Get Info from the list. If you’ve got a Retina display-enabled Mac, you can follow these steps to launch an app in standard resolution instead of Retina Display resolution: 1) Open a Finder window and navigate to your Applications folder.
![]() However, the Color LCD profile is close to the sRGB profile, so I’m not sure why the Color LCD profile is even included with the iMac because its gamut is too small to describe the iMac display.Color LCD gamut over iMac display profile gamut (left), and sRGB profile gamut over iMac display profile gamut (right)At the Apple Store I didn’t have time to do much testing with real images, but an excellent article at astramael.com ( The Wide Gamut World of Color — iMac Edition) does use sample photos to show the tradeoffs between the Adobe RGB, P3, and sRGB color gamuts. According to the Apple Developer API Reference, Display P3 “uses the DCI P3 primaries, a D65 white point, and the same gamma curve as the sRGB color space.” It looks like Apple wanted to keep as many sRGB characteristics as possible as they expanded the color range to the P3 color gamut.What if we compare the iMac profile to the Color LCD profile that is also found in the list of display profiles on this iMac? The Color LCD profile gamut is much smaller than the iMac and P3 profiles. A backlit device display reproduces images differently than a cinema projector in a dark theater, so when Apple adapted DCI-P3 into their own profile that they call Display P3, Apple adjusted their version to be more consistent with typical computer displays. The difference between the Display P3 and iMac profiles is probably that the iMac profile represents the color gamut that the display panel is actually capable of reproducing.However, neither the iMac display profile nor Display P3 is exactly the same as the DCI-P3 digital cinema standard. Games Retina Display Movie Theaters OrThe Digital Cinema Initiative (DCI) standard also specifies a gamma of 2.6 and a luminance of 48 cd/m2 or 100 cd/m2 depending on whether you’re targeting movie theaters or television, and there are also various white point standards. The Apple Store I went to had no problem with me copying screen shots and profiles to my USB flash drive.Note that for true digital cinema work, just having a P3 color space isn’t enough. For that reason, both that author and I are comparing the Apple-supplied profiles that we found on the iMacs themselves. They report that the Apple Store staff did not allow them to connect and run the colorimeter. Quickbooks for mac 2017 user guideWhen those untagged color values are displayed on a larger gamut display, if their gamut is simply scaled up to match the larger gamut the color values can end up further out than they should be in the larger color space, appearing oversaturated.I believe I saw evidence of this when looking at the Late 2015 Retina iMac. This can happen when the color values of untagged objects are defined in a smaller color space such as sRGB, which is usually the case. How does the iMac P3 display handle untagged objects?One of the challenges of wide gamut displays is that the colors in untagged objects (objects without a color profile) can appear oversaturated. The tweets below explain why untagged colors in Safari are no longer as screwed up as they used to be on a wide gamut monitor: Safari now does the right thing, in that when Safari 9 sees colors without a profile (untagged) it will assume the colors are in the sRGB color space and convert to wide gamut from there. I see the same effect on untagged objects when my NEC PA272w display is in wide gamut mode.I hope to hear more about general untagged color handling on this display from anyone who knows more or is able to test it more thoroughly.As for the Web, it looks to me like untagged image and CSS colors are rendered correctly in the Safari web browser, but not necessarily outside Safari, such as in the Finder. To me this indicates that Apple may not have completely color-managed Mac system elements for wide gamut displays. Not just “this display shows more colors” saturated, but some colors seemed to have that unnatural “radioactive” glow that’s associated with untagged objects on wide gamut displays. Even when I turned up the brightness of the MacBook Pro all the way, the colors in the iMac screen were much more vivid. I opened the same windows on the iMac and on a 15” 2015 Retina MacBook Pro near it. When I searched the system help files of the iMac for “P3” or “sRGB” nothing came up. The Retina iMac doesn’t do it either way, or at least not in any way that I was able to find. Some let you switch to an sRGB emulation mode through a control on the front panel of the display with others you switch modes using utility software. Colors can appear unnaturally intense if they’re not mapped properly to a wide gamut display.Professional wide gamut monitors work around the oversaturation problem by providing an option that restricts their gamut to sRGB. — Ricci Adams OctoDoes the iMac P3 display have an sRGB mode?Wide gamut displays can be a challenge for developers of games, mobile apps, web sites, and other content targeted for average consumer displays, because of the oversaturation of untagged content that I just described. Safari will correctly treat CSS colors as sRGB, and render wide-gamut images.For web developers on the 2015 iMac: only Safari 9 correctly treats CSS colors as sRGB. So choosing the sRGB profile can’t and won’t make the monitor display the sRGB gamut. A display profile describes the color behavior of the display, but it can’t change that behavior. That is not going to help, because that’s not how display profiles work. If you have more information on this, please post in the comments.You may sometimes see a suggestion to open the Displays system preference and select the sRGB profile. I’m not 100% sure that there is no sRGB emulation mode on this display, but that’s how it’s looking.
