Christine,

As Steve wrote, all (most?) standard laptops and desktops would not have ability for video in, only video out.

There are small stand-alone LCD monitors (5"-10") that have HDMI inputs, and, I suspect might even work on batteries. I've seen those used for the video work with Canikon DSLRs.
As I pointed out in another thread, this Amazon store sells parts for
building rigs that would allow mounting such monitors to a camera:

I am sure there are others.


I also wanted to add a caution: I've never looked or tried, but before investing in any additional equipment, I'd check if the current Pentax DSLR firmware allows _LIVE_ displaying via HDMI. I know that some cameras that have HDMI connectors only allow playing recorded videos via them, say on a TV, not live display while you are shooting.


Finally, 2.5 years ago, I was asking for possible tethering solutions here. I remember there were a few options I considered, but since the immediate need disappered before I tried any of them, I don't know what would work. I don't remember all the details at the moment, but you can take a look at this thread:

Hope this helps,

that won't work; Christine would need an HDMI video capture device; i don't know the market, but something like this:


<http://www.amazon.com/StarTech-com-USB3HDCAP-Video-Capture-Device/dp/B00PC5HUA6/ref=pd_cp_e_0>

but since she has a pre-Thunderbolt Mac, she also doesn't have USB 3 and i suspect USB 2 is not fast enough to keep up; maybe if you found a device that broadcast a stream onto wifi .
