Globally lock output settings for hardware playback

Premiere Pro is the only post app i use on a daily basis where the hardware output signal follows the source. While this makes sense on paper, it doesn't work well in practice. The two biggest flaws with this concept are the proliferation of UHD content but not UHD monitors, and social media deliverables. 

UHD content on a non UHD monitors means the signal has to be cross converted to display a signal. 

Social media deliverables like 9x16 don't display properly on hardware devices like BlackMagic ultrastudio. 

The solution is to introduce the ability to lock playback for hardware devices to a standard. This is how Davinci Resolve, Silverstack Lab, Livegrade and FCPx all work. 

If i can set my output to 1080p23.976 globally, then Premiere can push all my signals into that box. My hardware and Flanders monitor would be much happier.
