Got this for the 4K display. Works precisely as advertised. Very fast and allows backgrounds for Zoom. Just one thing, the Display Port to HDMI converter is installed, which is nice but the HDMI does not carry the audio signal. It displays video beautifully but, the audio out is a separate port. It seems obvious now but, I did spend some time trying to troubleshoot the no HDMI audio 'issue'. There is no audio problem with the unit.
