So I just realized that the editor resolution is apparently in 1280x720. Is there a way to push it to run 1920x1080? I thought there was a setting for this a year or so back, but now I can't seem to find it in the Editor. The closest thing I can find is the NDI Settings as well as the ATVO settings itself - which I have it set to 1920x1080. I can't seem to find a similar setting in the editor.

When you create a new theme you can choose the resolution. After you've created it, you can change it by selecting the main theme item in the Theme Explorer tree and changing the properties. Note that your widgets will not grow/shrink when you change resolution.
