You will need to know the VESA pattern (bolt pattern) on the back of the Tv you plan on using. It will be measured in milimeters ie; 100 X 100, 200 X 200, 100 X 200 etc. Once you find that out, call Brandon at Prime time & let him know which size you need for the back ov the Tv and he'll get one to you.
