*Make sure power is on *Check the socket and power cable
1. Make sure the 3-in-2 cables are well connected.
2. If you use a desktop, make sure the HDMI port is plugged into the graphic card on the
tower, but not into the motherboard.
3. If you use a Windows OS computer, make sure to press ''Windows+p'' on keyboard,
then choose Duplicate or Extend. Don't choose Computer Only or Projector Only.
4. If there is no HDMI port on your computer, you need an extra HDMI adapter. We DON'T
recommend a USB to HDMI adapter. Also we don't recommend a USB hub. We recom-
mend DVI/ VGA/ Display Port/ Type-C/ Thunderbolt, etc to HDMI adapters.
1.Make sure the power cord is well connected.
2.Try different power socket.
1. It is because you are under extended mode right now. It is normal situation.
2. If you are not familiar with extended mode, we recommend you to use in Duplicate/
Mirror mode. Windows OS: Press keyboard combination---windows+p---then choose
Duplicate
Mac OS: System Preference---Displays--- Arrangement--- Check "Mirror Displays"
3. If you decide to use in Extended mode. Make sure to choose pen display as Work Area
in GAOMON Driver. It is usually ''Display 2''.
Please set the display resolution with 1920 x 1080.
Check the pins of the signal wire are not bent or fractured.
As the regional color temperature is different, so minor chromatic aberration is a normal
phenomenon.
It is likely that there is electric equipment nearby that brings about electronic interference.
