Extended Display
, available in the “Control Panel\All Control Panel Items\Display\Connect to a Projector”

9. Observe that the DisplayPort video is transferred from the host (PC) to the display monitor through the USB Type-C port.
10. Also observe the enumeration of the USB drive connected to the Type-C Multiport adapter on the host PC connected via
the CY4521 EZ-PD CCG2 EVK. Verify functionality by accessing files on the connected USB drive from the PC.
5.3.3 Common Problems and Troubleshooting
If the demo is not functional, follow these guidelines to troubleshoot:
1. Ensure that the CY4521 EZ-PD CCG2 EVK
’s base board and daughter card are powered by verifying that LED1 on the
CCG EVK base board and LED2 on the CCG2 daughter card are glowing green and LED2 on the CCG EVK base board
is blinking orange. If LED2 on the CCG EVK base board is not blinking, the CCG2 device is not active. Assert and release
the reset button (SW1) on the CCG2 daughter card.
2. Ensure that the CCG2 daughter card is mounted properly on the CCG EVK base board. All connections between the two
boards must be completely mated.
3. Ensure that the boards are powered before connecting the DisplayPort cables.
4.
Ensure that “Extended Display” in enabled on the host PC.
5. If the PC video is not displayed on the monitor, assert and release the reset button (SW1) on the CCG2 daughter card.
6. If the SuperSpeed USB device does not enumerate as expected on the PC, unplug the device and then plug it back in.
It should enumerate as a SuperSpeed USB device this time.
7. While connecting the video output from a Windows 7 (32 bit/64 bit) based PC to a 4K monitor through the CY4521 EVK,
ensure that the PC uses the latest version of the driver for the Display adapters. Update the driver as required.
