I am supplying 5V power to my esp. Would that mean the data cable is only providing 3.3V?Reread my question. If you are going directly from an esp chip 3.3v to a pixel you will have problems with a distance greater than about 50cm no matter what cable you use. You need to use a buffer chip or famp to bring the data voltage up to 5V
So if I were to create my own differential controller using MAX485 boards or using pre-built boards, would that solve my issue?
Do I need to bring the data up to 5V from the esp before it reaches the differential transmitter?
