They want to know if audio can come from HDMI and video from DisplayPort using separate connections. Ideally, both cables would go into the monitor, with HDMI handling sound and DP handling visuals. This setup likely works only if the monitor supports that specific function. Usually, choosing HDMI as the source makes the monitor use HDMI for both image and audio, while DP alone won’t pull in any audio. DP can also carry audio, so quality shouldn’t differ much. It’s unclear why they’d need this special feature.
Connecting your PC to a soundbar through HDMI or a surround setup ensures the audio reaches that device properly. While my display uses DisplayPort with built-in speakers, my sound goes to my TV or soundbar via HDMI.
Open Windows sound settings, choose HDMI as the default. You could also turn off every other audio device just in case Windows makes a mistake later. If you don’t rely on HDMI for sound, consider keeping another device enabled as a backup.
You can lower latency by sending video via the DP port to your PC monitor and audio through HDMI to the AV amplifier. The Oppo 203 4K UHD model has two HDMI outputs—one for video and another for audio. If you turn off multi-display mode in the NVIDIA control panel, the PC will send clean audio only.
