1.Checked the physical connnection between TE60 and the Laptop used for presentation source, confirmed that:
The TE60 used HDMI IN port to connect to the Laptop, and the connection was very good.
2.Checked the presentation source physical connection via WEB GUI of TE60(Page: Maintenance->System Status->Input Interface Status), and found that:
It showed the format of presentation source normally.
3.Checked the settings of Video Input via WEB GUI of TE60 (Page: System Settings->Input/Output->Video Input), and found that:
The Input source was set to HDMI(HW) ; It should be HDMI, but it's still failed to share presentation after changing it to HDMI.
4.Checked the settings of Presentation source via WEB GUI of TE60(Page: Device Control->Video Control->Local Video Settings), and found that:
The Presentation source was 2 PC IN(default settings), not HDMI IN. It should be consistent with the physical connection.
After changing it to HDMI IN, it's successful to share presentation.
When meeting such a problem, the steps can be followed to do the trouble-shooting:
1.Check and confirm the physical connection between Terminal and Video/Presentation source;
2.Check the settings of corresponding Video Input;
3.Check the Video/Presentation source selection.
