Display Maestro gives you full control over attached displays, allowing the use of all available resolutions and bit depths. Mac OS X 10.10 Yosemite strips out the useful ability to set specific resolutions and presents a more user-friendly approach.
Experienced users, especially graphic designers and presenters, demand more precise control of their devices. Access exactly the resolution you need with Display Maestro's traditional-Mac-OS-like menu.
Pro users can also view advanced resolution and device information ranging from gamma configuration, RGB color points, scaling, samples per pixel, screen dimensions, device vendor IDs, refresh rate, manufacture dates, dots per inch, Retina (HiDPI) status, and more.
Also view feature information such as if the following are enabled are supported: pan enabled, simulscan enabled, is stretched, television mode, Desktop GUI support, interlace mode, mirroring supported, built-in, high-resolution capable, accelerator backed, and more.
