QuickRes is the best way to switch between screen resolutions on your Mac 🖥

With any MacBook Pro with Retina Display, QuickRes will enable you to bypass Apple's restrictions and safely set your resolution all the way up to an extreme native 3840x2400 and on a 5K iMac you can reach the highest resolution of 7680x4320! With Macs that have legacy displays, you can set your resolutions to things you've never seen before, including a HiDPI mode, which is as close as you can get to a Retina Display on a standard monitor.

*Although we cannot confirm this, many users report better battery life and higher performance when using higher resolutions on computers with Retina displays
