Today only, Microsoft Store offers its Microsoft Dual-Band Wireless Display Adapter, model no. CG4-00001, for $39.95 with free shipping. That's tied with our mention from last week as the lowest total price we've seen. (It's also a current low by $10, outside of the price below.) It's compatible with Miracast-enabled Windows 8.1 devices and Miracast-enabled Android devices with v4.2.1 or later. This adapter allows you to mirror content from a compatible device on an HDTV or monitor.

A close price: Triplenet Pricing via Amazon charges $40.85 with free shipping.
