How do I Export a still at 4K?

I'm exporting stills from the color page but they are all coming out as HD. I need it to be source resolution (3840x2160). Why cant I get a 4K still out of Resolve? Even my timeline is set to 3840x2160.

nobody knows how to export a 4k still from Resolve???

Well, it seems nobody is seeing the same behavior. If I use a timeline in 4K, grab a still and export that frame, it is saved just fine in 4K. Are you sure about your timeline resolution, BTW?

As far as I can determine, the stills grabbed in the stills bins are at the same resolution as the Project settings output scaling.
