A:Answer Hi there, The 85Q950TS uses a different connection on the one connect than this model. If you are in need of a longer cable than the 15 ft. included with the TV, you may want to reach out to Samsung Support to see if there is an extension offered. Please reach out to Samsung Support via any of these options:
