Originally posted by Class A If streaming to an external monitor (e.g., smartphone or tablet) works well then I'd say that beats an articulated monitor easily.
Actually, HDMI monitors are the de-facto standard for video operators now and there are nice ones even adding peaking. No problem to use them with the K-5.
However, some monitor the clean HDMI output directly (requiring a much more expensive rig) which has full HD resolution beating the LV monitor. That's not possible with the K-5 as it outputs a lower resolution video over HDMI during recording.

No reason to speculate, you could have asked a question instead.
LV over WiFi or USB is both reliable and fast. Same quality as on the rear monitor. Just some extra latency which however, isn't that much larger than the K-5 already has to its rear screen.
I tried with Helicon Remote over USB (Nikon), iUSBPort-Camera over Wifi (Nikon), Builtin-Wifi (Sony).
I know the inner details of the protocol used by Sony. They transmit a stream of 1 JPG/frame over http (so, a VGA-sized MJPG stream basically). Which should be no more than 10 Mbps (for 30-50 KB JPGs). No problem at all for a current Wifi, esp. over short distance.
