Belkin ScreenCast AV 4
Wireless HDMI transmitterBy Harley Ogier, Auckland | Wednesday, 20 June 2012
Belkin’s Screencast AV 4 allows you to wirelessly connect up to four HDMI video sources (Blu-ray player, game console, etc) to a single display, such as an HDTV or projector. It advertises a range of up to 30 metres line-of-sight and support for 1080p Full HD.
From a glance at the toaster-sized box, you can tell that this is no miniature plug-in adapter. The Screencast consists of two lightweight but bulky units: a transmitter that you situate with your AV gear (235 x 145 x 35mm), and a receiver that goes with your display (175 x 132 x 35mm). Each uses its own mains adapter, so you’ll need a spare power point by your AV sources and your TV.
Setting up the receiver is simple: plug in the power adapter and connect the receiver to your TV using the included metre-long HDMI cable. Transmitter setup is a little more complex, but only barely. Four HDMI ports on the rear connect to your devices: we tested with an HDMI-enabled DVD player, Blu-ray player and Freeview tuner, leaving one port free. You’ll need to supply your own HDMI cables to connect to the transmitter. Finally, plug Belkin’s ‘IR Blaster’ into the transmitter – this is a nifty little four-headed cable, each head tipped with an infrared LED. You run one of these to the front of each of your devices, lining it up with the infrared receiver – where you’d point the remote control.
While the transmitter sends Full HD video from your Blu-ray player or Freeview box to the receiver and thence your TV, the receiver sends back any infrared signals it receives from a remote control. You can stash your AV gear in a cabinet – or in another room – and still control it. It’s a common feature among wireless AV devices, not unique to the Screencast, but a good one to have.
Once youve plugged everything in, you use the three-button remote to go through some minor on-screen setup (it took us less than a minute), then you’re ready to go.
1080p video comes through beautifully and without stuttering or artefacts, along with 5.1-channel surround sound. None of our test AV devices posed a problem. Video also streamed fine from an HDMI–equipped PC, though we were unable to make a successful connection from a MacBook Pro using the official HDMI adapter.
We couldn’t test the full 30 metre line-of-sight range, but ten metres posed no problem and five metres through a couple of indoor walls worked equally well.
There’s minor lag when running at 1080p, but not enough to be noticeable – even if you’re running audio from your AV gear and sending video via the Screencast, the two seem perfectly in-sync. Lag becomes noticeable when gaming, however, especially in twitchy first-person shooters. It’s not really the ideal setup for competitive Call of Duty multiplayer. Keep your console connected directly to your TV, and save the Screencast for less-interactive experiences.
The only other downside is the price. At $400, it’s likely to be cheaper than a professional home-theatre wiring job, but not a clever-Kiwi’s DIY job. If you have a cinderblock room that makes wiring difficult, or you’re in a rental that you can’t drill holes throughout, the Screencast is worth every cent. Otherwise, cabling is likely to be the cheaper and simpler option.
