TMDS181: TMDS181: No signal output when configured in i2c mode

Part Number: TMDS181
Other Parts Discussed in Thread: TPD12S016

Hi ,all,

Using TMDS181 and TPD12S016 to build the HDMI signal channel between FPGA and display (FPGA is the sending end and the display is the receiving end).

The current problem is: HDMI don't output to 4K or 1080P in i2c mode ,but HDMI signal to display in pin strap mode.

Do you have any suggestion why TMDS181 don't have output ?
