德味儿推荐：
6.3折95美元，最大支持720p的视频无损输出到电视，静态图片最大支持1080p无损输出，视频和静态图片大于该尺寸也可以输出，只是会自动缩小画质到支持的最大格式。
投影仪等可以连接vga和hdmi的视频回放设备，因为接收端使用这两个接口，接收端的造型不错，大底座头顶鲨鱼鳍天线，放在电视顶部很好看。
音频输出只支持立体声3.5mm接口，比较普通。
最远连接距离30英尺。
电脑输出端是一个小巧的usb设备。
支持windows和macos系统，支持所有有线连接画面输出模式：镜像，扩展等。
包装重量不到1磅。
总得来说，视频不能1080p无损输出，音频没有5.1声道，所以不是高端的视频输出方案，但是在无线视频输出方案上，局限于无线数据承载量，这个产品已经是该领域的搞水准了。实用性么，如果没有专门配HTPC给电视，这个方案可以让用户不需要将电脑和电视整天插来插去的，但对于画质音质有高要求的，还是用有线方案吧。更多介绍请点击more看全文。
