A:Answer Hi tricksey,
Thank you for your inquiry. We highly recommend the use of the supplied TV stand. However, you can install a television swivel base. Please contact your local retailer to find a VESA stand that meets the size of your TV, your wall or environmental requirements, and stylistic preferences. You may open this link below for more information of VESA Hole Patterns for TV Wall Mounts. I hope this helps.
