Resolume Forum

Found this little testcard application today (windows and source code only, no mac. maybe someone can make an ffgl plugin with the source!)

You can generate testcards for different resolutions, but it only supports resolutions of your main monitor.

For OSX: https://itunes.apple.com/us/app/testcar ... 9396?mt=12

Love that you can add your company name to it as well
