|Microsoft Wireless Display Adapter|
The ability to beam video to a HDTV screen without wires has been promised for quite some time, but the product methods on offer (DLNA, Miracast, Wi-Fi Direct) have proved to be disappointing, complex and/or problematic. This update adds an additional option.
Microsoft Wireless Display AdapterPromising easy setup and compatibility with both Android (4.2.1 and later) and Windows (8.1 and later), Microsoft Wireless Display Adapter comes close to hitting the mark. Setup is indeed easy (though not entirely free of problems, since more than one connect attempt may be needed), and audio sync and video quality are quite good (significantly better than Chromecast), but motion tends to be a bit jerky (1080p video tested over a short distance from Windows 8.1 with Intel i7 processor, Intel HD Graphics 5500, and Intel 802.11ac adapter), clearly not as good as HDMI cable connection. (Frames are probably being dropped to maintain streaming.)
DLNAMany "smart" HDTV sets claim DLNA Player support, which should make it possible to beam video to them over a network connection (wired or wireless), and the ubiquitous Windows Media Player includes DLNA Server support. (See Media Streaming with Windows 7) But try to make it work and you're very likely to run into compatibility problems, since many HDTV sets are very fussy about what video formats they will (and will not) play, and Windows Media Player does not support transcoding between formats. (While there DLNA servers that can transcode on the fly, they can be difficult to set up, and the resulting quality is often mediocre. Your best bet is to use Handbrake to transcode to MPEG-4 in advance.) But even when it works, video quality is noticeably inferior to a wired HDMI connection.
Bottom line: Beaming of HDTV video without wires remains a work in progress.
- For best quality use a wired HDMI connection.
- If you must have wireless, Microsoft Wireless Display Adapter is the best bet.
