一、如何將電腦螢幕投射到電視上

如今，在家中享受電腦上的內容已成為一種日常需求。而要將電腦螢幕上的影像擴展到更大的電視螢幕上，就需要將電腦螢幕投射到電視上。這不僅讓我們能夠更好地觀看電影、玩遊戲，還可以將電腦上的內容分享給家人和朋友。本文將向您介紹幾種簡單易行的方法，讓您輕鬆實現將電腦螢幕投射到電視的目標。

使用HDMI連線傳輸

使用HDMI連線是將電腦螢幕投射到電視上最常見的方法之一。 HDMI（High Definition Multimedia Interface）是一種常用的數位音訊視訊接口，提供高品質的傳輸效果。要使用HDMI連接傳輸，您需要具備以下條件：

一條HDMI線一台具備HDMI輸出接口的電腦一台具備HDMI輸入接口的電視或投影機

接下來，您只需要將HDMI線纜連接電腦和電視，然後選擇對應的輸入來源即可。您的電腦螢幕上的內容將會傳送到電視螢幕上，實現螢幕投射。

使用無線投影設備

除了使用有線的HDMI連接，您還可以考慮使用無線投影設備，將電腦螢幕投射到電視上。這種方法比較便捷，不需要擔心線纜的限制。以下是一些常見的無線投影機裝置：

無線顯示轉接器：這是一種將電腦螢幕透過Wi-Fi傳輸到電視的裝置。您只需要將轉接器連接到電視的HDMI介面上，然後透過軟體安裝和設定即可實現投影機。 電視盒子：有些智慧電視盒子具備螢幕鏡像功能，可以將您的電腦螢幕投射到電視上。您只需要將電視盒子連接到電視，並設定連接電腦的無線網路即可。 智慧電視：許多智慧電視都支援無線投影機功能。您只需確保您的電腦和電視連接到同一個Wi-Fi網絡，然後透過電視上的投影功能，選擇要投射的電腦即可。

使用投影機

如果您沒有電視，但有一台投影儀，您也可以將電腦螢幕投射到投影機上。使用投影機的步驟與使用電視類似，您只需要將電腦和投影機透過HDMI線連接，並選擇正確的輸入來源。

無論您選擇哪種方法，將電腦螢幕投射到電視上都是一種便捷而有利的方式，既提供了更大的螢幕空間，又讓您更好地享受電腦上的內容。希望本文的內容能幫助您，感謝您的閱讀。

Select Yes, and your phone screen will be displayed on the computer. On. Expanded information Multi-screen interaction refers to the use of IGRS protocol, Miracast protocol, etc., through WIFI network connection, on different multimedia terminals (such as common different smart terminal devices based on different operating systems such as Ios, Android, Symbian, etc., such as mobile phones, PAD, TV, etc.), it can perform a series of operations such as transmission, analysis, display, and control of multimedia (audio, video, pictures) content, and can share display content on different platform devices at the same time, enriching users' multimedia life. To put it simply, the screens of several devices can be connected and converted to each other through special connecting devices. For example, movies on mobile phones can be played on TV, pictures on tablets can be shared on TV, and computer content can be projected on TV. This is a technology that is quietly emerging nowadays.

4. Why can the current computer screen be projected onto the TV screen?

In the past, if you didn’t use a wire to connect your computer and TV, you had to first upload the video to the website and then use the TV to download the video. In this process, the path of the video signal was computer-router-website server-router- TV, and then you will find that if you save the website server step, it will not save time, effort and money. So when wireless technology improved, the Wi-Fi Alliance released the miracast standard. Devices that support this standard can share video screens directly through Wi-Fi. So now it is equivalent to you uploading the video signal to the router, and then the router directly sends the video signal to the TV.
