Also forgot to mention, I prefer to shoot around 18mm for product shots, so about 28.8mm full frame equivalent. When I'm talking in front of the camera, I would use either 30mm or just the 18mm.
But I do need that slightly wider look, so 12mm-14mm on GH3, on GH4 that would be around 12mm due to 2.3x crop.
Mine doesn't. I'm running hackintosh, and it won't recognize my 1440p as a main display automatically. If I unplug all other displays and restart, my screen looks like an awful 768p upscale, even if it shows 1440p selected in the scale setting.
Another annoyance is I like extending my workplace, but the dock stays on my TV unless I want the 1440p monitor to look awful.
Oddly enough if I set the TV as the main monitor (like the hackintosh does automatically) then my 1440p monitor scales properly.
It's almost frustrating, expect that hackintosh was free, so I can't hate. Just glad I Dual Booted with Windows, otherwise I'd be stuck removing Hackintosh later on.
