Users of the Dell 28 Ultra HD 4K Monitor - S2817Q may encounter no video on the display while it is configured in the HDMI 1.4 mode (Default) when connected to the HDMI port of a DA200 adapter.
Due to the DA200 limitation of HDTV 1080p resolution (1920 x 1080 pixels), the DA200 adapter is not a recommended adapter to use with the S2817Q.
The Dell 28 Ultra HD 4K Monitor - S2817Q has a default Ultra HD resolution of 4K (3840 x 2160 pixels) @ 30 Hz, HDMI 1.4.
If you need to use a system with a USB Type-C port to connect to a S2817Q Ultra HD 4K Monitor, Dell recommends a basic USB Type-C to HDMI cable (See Figure 2.).
