ユーザーは、ビデオ入力用の DVI ポートが 1 つと、ビデオ出力用の HDMI ポートが 1 つしかないデスクトップ コンピュータに新しいディスプレイを取り付けようとしています。技術者がセットアップを完了するには、次のうちどれが必要ですか?
正解:D
Explanation The technician will need to connect the DVI port on the computer to the new display's HDMI port. To do this, a DVI to HDMI cable will be needed. This type of cable will allow the computer's DVI video signal to be transmitted to the new display's HDMI port. A digital-to-analog converter (DAC) is used to convert a digital signal to an analog signal. An A/V switcher is used to switch between multiple audio and video sources and display them on a single monitor or display. A DisplayPort to HDMI adapter is used to convert a DisplayPort signal to an HDMI signal, but it is not necessary in this scenario as the computer has a DVI port and not a DisplayPort.
