The One Connect “cord” is lengthy, I would say about 8 feet long. I didn’t measure it before I installed the TV, but I was pleasantly surprised at how long it was as that was a concern of mine. The One Connect box is what allows the TV to be so thin – the power supply and all the myriad connectors are all on the box instead of the TV.
