supply near connector.
HDMI 5V supply to connector: Connect to +5V on
HDMI Connector.
Note:
Any ESD and/or EMI solutions must support targeted modes (frequencies).
Table 45. Recommended HDMI / DP observation (test) points for initial boards
Test Points Recommended
Location
One for each signal line.
Near display connector. Connector pins can be used if accessible.
Note:
Test points must be done carefully to minimize signal integrity impact. Avoid stubs & keep pads small & near signal traces
