什麼是 Displayport 與高畫質多媒體介面 (HDMI)?

Displayport 和 HDMI 是兩種流行的視訊和音訊接口,用於連接電腦、顯示器、電視 (TV) 和遊戲機等設備。它們的目的相同,都是傳輸高品質的音訊和視訊訊號,但它們之間也存在一些差異。

哪些設備通常使用 Displayport 和 HDMI?

大多數現代電視 (TV)、投影機、藍光播放器、遊戲機和筆記型電腦上都配備 HDMI 連接埠。另一方面,Displayport 常見於電腦顯示器、筆記型電腦和一些顯示卡上。

Displayport 和 HDMI 之間的主要區別是什麼?

顯著差異包括 Displayport 通常支援更高的解析度和更新率,使其成為遊戲、圖形設計和多媒體製作的理想選擇。 Displayport 還支援菊花鏈,其中可以使用單一 Displayport 輸出將多台顯示器連接成鏈。另一方面,HDMI 的應用更為廣泛,並且與更廣泛的設備相容。

我可以使用帶有 Displayport 的 HDMI 電纜,反之亦然嗎?

不可以,您不能直接將 HDMI 連接線連接到 Displayport,反之亦然。但是,您可以使用適配器或轉換器來彌補這兩種格式之間的差距。例如,您可以使用 Displayport 轉 HDMI 轉接器或電纜將 Displayport 輸出連接到 HDMI 輸入。

我應該使用哪個版本的 HDMI 或 Displayport?

您應使用的 HDMI 或 Displayport 版本取決於您的特定需求。 HDMI 2.1 是最新版本,支援 8 kilo (K) 解析度和更高的更新率。如果您希望您的設定能夠面向未來,那麼 HDMI 2.1 是一個不錯的選擇。對於 Displayport,2.0 版本是最新版本,也支援 8K 解析度。然而,Displayport 1.4 仍然被廣泛使用,並為大多數應用提供出色的效能。

使用 Displayport 或 HDMI 時是否有任何限制需要考慮?

Displayport 和 HDMI 都有一定的限制需要記住。 HDMI,尤其是舊版本,可能不支援與最新 Displayport 標準相同的高更新率和解析度。與 HDMI 相比,Displayport 電纜相對昂貴,尤其是對於較長的長度。此外,某些較舊的裝置可能僅具有 HDMI 或 Displayport 1.2 或更早版本,這限制了您可以實現的最大解析度和更新率。

Displayport 或 HDMI 可以傳輸音訊訊號嗎?

是的,Displayport 和 HDMI 都可以與視訊一起傳輸音訊訊號。這表示您可以將電腦或其他音訊視訊來源連接到顯示器或電視 (TV),並透過顯示器的內建揚聲器或外部音訊系統播放聲音。只需確保連接的裝置支援通過對應介面的音訊即可。

什麼是高頻寬數位內容保護 (HDCP)?

HDCP 是一種複製保護形式,可防止未經授權複製受版權保護的內容。 Displayport 和 HDMI 都支援 HDCP,並且通常需要播放受保護的內容,例如藍光電影和串流媒體服務。當使用相容的訊號源和顯示器時,HDCP 可確保內容安全傳輸和顯示而不會受到影響。

Displayport 或 HDMI 是否還有其他值得注意的功能或技術?

是的,每個介面都有一些特定的值得注意的功能。另一方面,Displayport 支援多流傳輸 (MST),可讓您將多個顯示器連接到單一 Displayport 輸出,並將桌面擴展到所有顯示器。 Displayport 還支援自適應同步,該技術透過將顯示器的更新率與顯示卡的輸出同步,幫助消除遊戲中的螢幕撕裂和卡頓現象。

另一方面,HDMI 具有乙太網路通道,允許相容設備共享互聯網連接,而無需單獨的乙太網路電纜。 HDMI 還支援消費性電子控制 (CEC),可透過單一遙控器控制多個裝置。

我可以使用 HDMI 轉 Displayport 轉接器將 Displayport 輸出連接到 HDMI 輸入嗎?

是的,您可以使用 HDMI 轉 Displayport 轉接器將 Displayport 輸出連接到 HDMI 輸入。然而,值得注意的是,此類適配器通常是單向的,旨在將訊號從 HDMI 轉換為 Displayport,而不是相反。確保根據您的特定需求獲得正確的適配器。

我如何知道我的電腦或顯示器是否有 Displayport 或 HDMI 連接埠?

要識別計算機或顯示器上的端口,您可以查找連接器附近的相應徽標或標籤。 Displayport 連接埠具有獨特的「顯示圖片 (DP)」徽標,而 HDMI 連接埠具有「HDMI」徽標。此外,您可以參考設備的使用手冊或規格,其中通常會提到可用的連接埠及其類型。

我可以在同一台裝置上同時使用 Displayport 和 HDMI 嗎?

是的,許多裝置(例如現代顯示卡和筆記型電腦)通常都配備 Displayport 和 HDMI 連接埠。這使您可以同時連接不同的顯示器或音訊視訊設備,從而為您的設定提供靈活性。您可以將一個介面用於主顯示器,另一個介面用於輔助顯示器,或根據相容性連接具有不同連接埠要求的裝置。

我可以使用 HDMI 或 Displayport 電纜進行純音訊連接嗎?

是的,HDMI 和 Displayport 電纜均可用於純音訊連接。如果您有具有音訊輸出的裝置以及具有 HDMI 或 Displayport 輸入的揚聲器系統或音訊接收器,則可以使用相應的電纜連接它們。這使您無需單獨的音訊電纜即可傳輸高品質的音訊訊號。

HDMI 和 Displayport 支援高動態範圍 (HDR) 嗎?

是的,HDMI 和 Displayport 都支援 HDR。但是,HDR 支援的等級可能會根據介面版本和裝置功能的不同而有所不同。 HDMI 2.0及更高版本支援HDR10,這是使用最廣泛的HDR標準。 Displayport 1.4 及更高版本也支援 HDR10,以及其他 HDR 格式,例如 Dolby Vision。

我可以使用 HDMI 或 Displayport 電纜將電腦連接到電視 (TV) 嗎?

是的,HDMI 和 Displayport 電纜都可用於將電腦連接到電視。如果您的電腦有 HDMI 或 Displayport 輸出,並且您的電視有相應的輸入,則只需使用適當的電纜連接兩者即可。這使您可以將電視用作電腦的更大外部顯示器,或在電視上播放電腦中的媒體內容。
