Multiple-Monitor SupportĪny Mac that supports multiple monitors can apply the specific color profile for each display properly, and therefore you should generate a separate profile for each display that you want to use for critical color evaluation. When a CRT's brightness level drops below 95 cd/m2 after you set the black level, it's time to start budgeting for a new LCD monitor. If you're trying to eke out another year of use from your beloved CRT, keep an eye on its brightness level when you recalibrate it. While manufacture of high-end CRTs has essentially ceased, they still have their diehard fans. All of these systems can calibrate both CRT and LCD monitors, and any of them will do a better job of keeping your displays accurately profiled than any of the eyeball-based tools. We like the Eye-One Display from GretagMacbeth, Color Solutions' basICColor Display, or the Datacolor Spyder. Several good, relatively inexpensive hardware-based monitor calibration packages are available. We believe that every serious Photoshop user would be better served by using a hardware color-calibration puck to measure the behavior of the monitor, along with its accompanying software, which will set the monitor to a known condition and write a monitor profile. Unless you work in a cave, however, you'll find it's extremely difficult to get consistent results with such programs, because your eyes-and hence your "monitor calibration"-adapt to changing lighting conditions. The free, eyeball-based, software-only monitor calibrators, such as the Apple Display Calibrator Assistant, are better than nothing. If you want to be reasonably confident in what you see onscreen, some kind of monitor calibration and profiling is essential. If you still have an old copy of Adobe Gamma, avoid using it, especially on an LCD monitor. Looking for Adobe Gamma calibration software? Starting with Photoshop CS3, Adobe Gamma is no longer included (or recommended).
If you have a 3D video card that's sufficient to run general CAD programs, it's good enough for Photoshop Extended.

But you may not have to upgrade your video card.
The 3D capabilities of a video card used to be irrelevant to Photoshop, but since the addition of 3D and video editing in Photoshop CS3 Extended, 3D graphics hardware now comes into play.

If your video card supports OpenGL, you may see new, smoother panning and zooming options in Photoshop CS4, such as free rotation of the canvas. Photoshop CS4 is the first version of Photoshop that can take advantage of a video card's graphics processing unit (GPU) for some display operations (not image-processing operations, though). If you're running multiple large monitors, try starting at 512MB. Aim for a video card with lots of video RAM onboard-at least 256MB, and preferably 512MB. The one video card spec that affects 2D Photoshop performance the most is video RAM. The bottleneck in redrawing Photoshop images is almost never the video system-it's getting the image data out of RAM (or even worse, from disk) to the video system. Video Accelerationįor pure two-dimensional (2D) image editing, you probably won't benefit from spending more money on the kind of high-end three-dimensional (3D) video card that makes gamers happy. The good news? If you don't have an OpenGL video card, you aren't missing out in terms of performance. It makes image display smoother, and, through the new display features, more interactive and convenient. The new OpenGL support in Photoshop CS4 doesn't accelerate image processing or speed up image display. But because monitor companies like to brag about brightness, some inexpensive LCD monitors can't be turned down that far! To do this, a monitor must reach the optimal brightness range for calibration, typically between 100 and 120 candelas per square meter (cd/m2).
Maximum brightness is meaningless for photo editing, because what really interests you is whether the monitor can give you a good black level so that you can judge shadow detail. Contrast ratios are not standardized among manufacturers and often don't take calibration into account. Unfortunately, reading technical specifications such as contrast ratio and maximum brightness won't help you. When you shop for a monitor for Photoshop use, the primary criterion is whether the monitor accurately reproduces a wide range of color after calibration. Liquid crystal display (LCD) monitors have essentially replaced bulky cathode ray tube (CRT) monitors in most studios. Real World Adobe Photoshop CS4 for Photographers
