HDMI向下相容DVI，利用轉接頭或轉接線；而DVI必須有HDCP認證才能接收HDMI訊號源
打個比方，電腦的顯卡是DVI輸出介面，螢幕有HDMI輸入端子
則利用DVI to HDMI或HDMI to DVI線材、轉接頭，即可顯示畫面，但無法傳送聲音
至於螢幕顯示解析度，就得視顯卡DVI所支援的解析度而定
但是若顯卡的DVI沒有HDCP認證，則沒有辦法輸出帶有HDCP加密保護的視頻資料，例如：藍光光碟(BD)
另一個例子，螢幕沒有HDMI端子只有DVI輸入介面，而DVD Player有HDMI輸出端子
則螢幕的DVI必須有HDCP認證才可以接收DVD Player HDMI端子輸出的視頻資料
由於HDCP授權金很高，所以支援HDCP的DVI螢幕會比一般沒有支援HDCP的螢幕貴上許多
XBOX360 Elite (HDMI 輸出) 可以透過 HDMI 轉 DVI
在沒有支援 HDCP 的螢幕正常顯示遊戲畫面.

HDCP-Free
Another aspect of the Elite that I really appreciated was the
complete omission of copy protection (HDCP) on the HDMI output.
There are hundreds of thousands of perfectly capable DVI monitors
out there that won't work with PlayStation 3 as they don't feature
the HDCP decoder chip required to descramble the image.
This is no problem for the Xbox 360 Elite, which only invokes the
HDCP encryption when viewing an HD-DVD movie.
