I did a little testing this morning. Macbook Pro OS 10.11.6 El Capitan, DataVideo SE-1200 switcher, cheap HDMI monitor.
The resolutions options are are available on the external monitor as soon as you plug in the cable (your KiPro in this case). Actually, plugging in the HDMI, gave me ONLY video resolutions, and doing the option+scaled gives you non-video resolutions.

The resolution settings are displayed on that 2nd monitor, but if there is a mismatch, you wont’ see an image or maybe a distorted image, and you may not be able to mouse to the resolution you desire. The case for SwitchRezX is that it is on your main computer screen and you can switch resolutions until you get one that works.

(while using SwitchResX)I have come out of both the HDMI and with a thunderbolt-to-hdmi cable with success.
Quitting SwitchResX and going back to Apple Display settings, all 3 monitors show up, display correctly and they are now mirrored from the desktop, but it held the video output resolutions on the 2 outputs. Unclicking mirroring, the display settings panels now jump to their respective monitors. This is OK since the resolutions held. Had they defaulted, you’d be back to the (possible) inability to see the see the settings box.
OpenOffice Presentation (I don’t have PPT on this MAC): Both outputs can be connected and you can choose which output to use. Choosing ALL sent output to only 1 output and a 4×3 presentation was right-justified in a 16×9 frame. I’m having a brain fart and can’t seem to figure out how to make a 16×9 presentation in OpenOffice, don’t know how that might look when choosing ALL. Choosing either external output worked fine.

Playback Pro: Can only output to a single external monitor, so both outputs can’t physically be connected simultaneously.
Hope this makes sense.
