I recently bought a wide screen CTL display for my MacBook Pro, in order to be kind to my neck while also keeping the same aspect ratio as my built-in display. I accepted Nancy’s recommendation of CTL as the price for this budget display was just over $200! Upon first use, I was dismayed to discover that the image quality was muddy and feared that I might have bought too low on the display food chain. However, the Apple display calibration tool saved me. It turns out that the display was calibrated to a PC gamma standard — the Mac standard (or better yet, a custom value) makes it look normal again. The image doesn’t look as great as an Apple studio display, but hey, it’s one-third the cost! The assistant is available in System Preferences -> Display -> Color -> Calibrate.
