Display Maestro 4+

Do not download it from here- Application will not open. Download from website in upper right corner. That one works good, but I was not seeing any more resolutions than are available in other freeware on the app store. I needed 1440x900 according to my monitor's manufacturer. This is not an option, not even an unsafe one. Obviously I don't know anything about what the requirements are for generating a list of resolutions to choose from, but it seems to me that the ability to imput custom sizes would be a desirable feature for the the target demographic- people that download this application in a desperate hope to make their hardware work. For now this will probably help most people, not everyone though.

I tried half a dozen apps/extensions to set screen resolution. I've used SwitchResX for yeats. They all work, but Display Maestro is the easiest to use. One nice detail is that if the menu bar is too full, so Display Maestro doesn't fit, then a popup appears teaching you a keyboard shortcut to open it.

This is a great little app for anyone who wants to change the resolution of their display. There was a time when it was easy to go to your System Preferences and change the resolution but those days are now long gone. This app is easy to use and shows a great variety of options. I was having trouble hooking up a large display to my iMac and with Display Maestro showing me the possible resolutions along with some online research I came to realize that I was using the wrong sort of cable which was why my choices in resolution were so limited.

Most people want their screen at maximum resolution and just want to keep it there. Display Maestro will help verify where your monitor is set and enable you to change it if desired. This is indispensable.
