Very useful free software to correct your display output resolution (a common problem for Mac OS X)
Hi all (Mac users),I just want to share this free software that I found during my last show. Since I upgraded to Yosemite, the external display resolution becomes quite sketchy and in Mac's display preferences only gives me very limited options, and I was going for pixel to pixel kind of work going thru another hardware switcher, so this can be a headache. I know there are lots of software out there that corrects it, but I just found this one which was very easy and useful to resolve this issue, I highly recommend anyone who deals with video outputs to have it.simply download [the free RDM.app](https://www.dropbox.com/s/5foco7kjl7cyu5b/RDM.tar), place in your application folder, then double click on it. the RDM software will appear in tool bar at the top, and you can then click on any resolution options.
