All TV manufacturers now provide fixing points on the back of their televisions where you can attach a TV bracket. The spacing of these fixing points is called the VESA spacing. VESA stands for Video Electronic Standards Association and is a worldwide standard for computer equipment and TVs. The VESA spacing of your TV is actually the distance between the fixing hole point spacing at the back of your TV.
Do TV brackets conform to VESA standards?
Most TV brackets that you buy today are VESA compliant. This means they have set spacing of mounting holes on the bracket. Most TV brackets have a few sets of mounting holes so larger sized TVs can be fitted onto the bracket if necessary.
If you already have a TV, take a tape measure or a ruler and measure the distance between the mounting holes on the back. You can then use this figure when you are going to purchase a TV bracket. Because the holes will then match up, you can mount your flat screen TV to the TV bracket really easily.
