We recently took an exclusive look at the Neoya Wii2HDMI adapter for the Nintendo Wii. It's a small $40 attachment that plugs into the Wii's A/V-out port and successfully carries 480p video and stereo audio over a single signal.
Since its launch, we've been desperate for a way to make the Wii an HDMI device because of how easy the interface is to work with; especially with the rise in HDMI-compatible receivers. Better yet, the Wii2HDMI adapter also offers a separate 1/8 inch audio-out for those receivers that can't process audio over HDMI.
We didn't notice any boost in picture quality (compared with component cables), thus the Wii2HDMI adapter should only be purchased as a means of convenience rather than an upgrade in resolution.
