We are now designing an HDMI output to connect to the TV,We found that HDMI devices could not be detected by TV if the connection was made with HDMI wires about 5m in length!When I use 2m length, TV can detect it! Is chip drive ability insufficient?Or which software or hardware parameters can be modified?How far can our chip connect to HDMI output?
