Fault symptom:
YOGA4 pro (YOGA900 13 ISK) uses the Type-c interface instead of the mini HDMI interface of the previous generation. In the environment where projection is required, you need to separately purchase the Type-c adapter cable.
Solution:
The available L2 test models are as follows:
VGA cable:
APPLE MJ1L2FE/a usb Type-c vga Multiport Adapter
UGREEN 40274 Type-C to VGA converter/adapter USB3.1 to VGA converter line
Biaze usb 3.1 Type-C to vga high-definition converter (only supports replication and expansion mode, single screen display will flash screen)
HDMI cable:
IPhone USB-C Digital AV Multiport Adapter converter
UGREEN 40273 Type-C to HDMI Converter/adapter USB3.1 to hdmi hd Converter line
CE-Link USB Type C to HDMI adapter
Tip: The specific problem needs to be analyzed. If the display itself is incompatible, the projection cannot be output.
