A.

When connecting Mac via HDMI cable, the monitor may show incorrect color and non-smooth tone.
 
In details, phenomena occurs such as:
 - High tone/low tone cannot be displayed correctly
 - Middle tones are skipped.
When these occur, we recommend using alternative ways than HDMI connection.

This is an intended behavior of Mac.

    When Mac has following output connectors, please use these connectors.
   - Thunderbolt 3 (USB Type-C)
   - Thunderbolt 2 (Mini DisplayPort)
   - DVI
 
2. Change the monitor settings (ColorEdge monitor only)
 
    You can avoid this HDMI issue with the following "Signal Format" setting.
 
     For CG277 / CG247 / CG247X / CX271 / CX241 / CS270 / CS240
      Optional Settings -> Signal Selection -> Signal Format -> HDMI
      Change the setting to "PC"
 
     For CG2700X / CG2700S / CG2730 / CG2420 / CS2740 / CS2731 / CS2730 / CS2400S / CS2420 / CS2410
