台灣在今年7月底終於販售了Apple M2 版本 MacBook Air ，除了更改原有的楔型外觀讓機身更輕薄外，也新增特殊色以及螢幕瀏海、還原舊有的MagSafe 充電埠、當然還有最重要的新晶片。本次我們將使用剛入手的 M2版本 MacBook Air 來實測與進階款電視棒的相容性，即將揭曉實測結果囉！
前置步驟：安裝與連接電視棒
本次使用進階款電視棒進行實測，使用時請確認電腦與電視棒連接到相同的WiFi 網路
實測1.螢幕鏡像輸出
螢幕鏡像輸出畫面會依照電視棒解析度進行調整，實際使用上是沒有問題的
實測2.播放YouTube
實測播放YouTube影片 ☑️
實測3.延伸螢幕
使用延伸螢幕 ☑️
總結
經以上幾種方式，M2 MacBook Air 無線投影電視棒相容性都沒有問題，另外我們也準備了小鴨版本的實測篇提供給大家呦！
電視棒 介紹影片
Miracast is a standard for wireless connections from sending devices (such as laptops, tablets, or smartphones) to display receivers (such as TVs, monitors, or projectors), introduced in 2012 by the Wi-Fi Alliance. It can roughly be described as “HDMI over Wi-Fi”, replacing the cable from the device to the display.
The Wi-Fi Alliance launched the Miracast certification program at the end of 2012.Devices that are Miracast-certified can communicate with each other, regardless of manufacturer. Adapters became available that may be plugged either into HDMI or USB ports, allowing devices without built-in Miracast support to connect via Miracast.In 2013, Nvidia announced support for Miracast.
Miracast employs the peer-to-peer Wi-Fi Direct standard. It allows sending up to 1080p HD video (H.264 codec) and 5.1 surround sound (AAC and AC3 are optional codecs, mandated codec is linear pulse-code modulation – 16 bits 48 kHz 2 channels).The connection is created via WPS and therefore is secured with WPA2. IPv4 is used on the Internet layer. On the transport layer, TCP or UDP are used. On the application layer, the stream is initiated and controlled via RTSP, RTP for the data transfer. (by Wikipedia)
