To enable HDR function, you need to have a compatible player and content.

are supported. Note that the 4K content on a FHD monitor get resized and is displayed at 
1920 x 1080. 
2.  Make sure HDR content is available. Content may come from a FHD/4K player.
3.  Make sure the player and the monitor have been connected via an appropriate cable:
• the provided HDMI / DP / DP to mini DP cable / USB-C™ cable (if available)
• an HDMI cable that is HDMI High Speed or HDMI Premium certified (for models with HDMI 
inputs)

• a certified USB-C™ cable (for models with USB-C™ inputs)
Enabling HDR function
If the instructions in Working with HDR technology on page 39 are followed and the input 
content is HDR-compatible, the OSD message HDR: On is displayed on the screen. This

Press   on the remote control (EW3280U) or the HDRi hot key (EW2780U / EW2780Q) 
to bring up the HDR settings and select from the list. Alternatively, go to Color > HDR Mode 
for selection.
Enabling HDR-emulated mode
If the connection is complete and no OSD message is displayed, this means the content player 
and/or the content are not HDR-compatible. The monitor stays to the color mode recently
