Which Pentax DSLR models have active video output via HDMI while recording?

I am looking at getting a brand new, latest model camera for video recordings with which I can use an external EVF and/or external LCD monitor for framing/focusing while recording video. To do this, the camera should be able to give out a an active 1080p or at least 720p video via the mini HDMI jack while recording said video internally. Or, at least a 480p standard-def video if it also has an analog AV output port besides the mini HDMI.

Would anybody know which Pentax DSLR model will let me do this? Plug-in via HDMI port (or analog jack, if any) an external EVF or LCD monitor for framing and focusing during video recordings to the camera's flash card. Obviously, the signal coming out of the camera would need to be ACTIVE, i.e. continuing regardless whether I am recording or not recording with the camera.

Thanks!
