What's the latency like? Is it better than cheaper alternatives?
Another concern I have is that my gaming rig is connected to my monitor through HDMI and I don't really want to have to mess about switching between the WDA and my HDMI cable - any solutions?
Also, powering it is a concern. Sounds like it would be useful to take out of the house and use on the move, but requiring a power supply sounds like it would limit the device.
Ahhh, great questions and concerns.
I can tell you that at home on my network there is practically no latency and am totally comfortable referring to it as "instantaneous." But I haven't had an opportunity to test it on the road, where I always use my Mi-Fi device.
It does cost more than similar devices but as I previously stated, it doesn't require the use of a specific app in order to stream content.
So your monitor only has one HDMI input? That would be surprising because I'd expect at least two. Anyway, if there's only one, you can always get an HDMI Switch and some of these intelligently automatically switch, based on active input data (search
Amazon, for example).
I, too, was originally concerned about powering such devices and when I was researching and read the instructions "plug it into the HDMI
and USB ports of the TV," my first reaction was that not all TVs have a USB port or one necessarily close enough to an HDMI port. But as a friend pointed out, in such situations you'd need to use an adapter to plug to your PC, the wall socket, etc. Anyway, that's the way all these devices work, but it would great if they could also be self-powered by lithium battery or something.
But at home on both my TV and A/V Receiver, I have a USB port right next to an HDMI port, so no power issues whatsoever (I have it connected t my A/V Receiver). On the road, however, I used to travel with a mini-DP-to-HDMI cable, but that's now replaced with USB Extension cable (in the event that there is no USB port or it is not close enough to the HDMI port).
