Figured there would be some people here interested in this..
The Belkin Screencast AV4 has come down a lot in price over the last 3-6 months at $150 (at Harvey Norman) and $140 at officeworks. Staticice can't find anything cheaper.
We got one for work the other day due to cables in walls getting a little lengthy and causing picture quality issues. It worked out cheaper than getting an electrician in again to make modifications or install amplifiers and probably shouldve been done in the first place.
It can take 4 HDMI inputs and send the signal wirelessly to a HDMI out (tv/projector). Works fine with computer, compatible with 3D 1080.
I tested it at either end of the office (30m~) with only glass in the way and it worked fine still. Even trying in different rooms it worked okay through the walls. It comes with a remote control extender so you can shoot your remote at the box at the tv, and have the output devices in another room receive the IR signal (though we are not using this as its all setup in one room).
Super simple set-up, plug in and click OK on a remote a few times and it just works. No more complicated than using an actual cable IMO. HDMI is sent over 5ghz.
Physically the receiver is about the size of a standard home router, and transmitter not much bigger.
I would recommend this to anyone who needs to get HDMI to different rooms (i.e. use a PC in another room as your HDTV), want to setup output devices at different part of room (tv on wall), or needs to setup cables running along a room (but doesn't like the mess).
Note: There are two screencast versions, this one has the AV4 at the end. The other version only has a receiver box and uses Intel's WiDi for sending video from a computer over wireless without hooking a HDMI cable in - so no good for blueray, etc (unless they are compatible?). The Non-AV4 version is cheaper again.
How far were the HDMI cables being run in your case Jerry?
at a rough estimate about 15m - which could also be due to cable quality - either way it was cheaper to do this than to re-wire or otherwise
$140 seems like a good price. Is there any latency?
I can run a fast paced test on it in about a week when im in the office next - there is this video on youtube i didnt watch fully but they were comparing it against a 60ghz system: https://www.youtube.com/watch?v=xXyhKMadKhc
see 6-8 minutes or watch from beginning.
they said they didnt notice any lag caused by these
So the PC is in another room, how do you control stuff?
IR remote + IR extender.. or tablet/phone as wifi mouse/keyboard (plenty apps for this)
I had these installed behind the tv's (one pointing upwards to the ceiling, and two paired on the same wall to run concealed wires between the tv and another device) and one behind my computer pointing upwards
Thermite, I wired up some wall plates with speaker wire (so instead of being an 'open to the wall cavity' type wall plate, it was the banana plug type) at my parents place. Aside from crawling around in the roof cavity and the associated d*** around feeding cables down the wall space, it wasn't much work, and means a cable free lounge space.
