Mount World 1056 VESA 200 x 200 Universal Adapter for Medium Mounts by Mount World

excellent

If you have a 4"x4" mount and an 8"x8" pattern on your TV (or anything in-between), this template is perfect. It comes with usable mounting screws, washers, spacers and even gripping bolts. Worked perfectly for me. It is made of steel, and the bolt pattern options for the smaller mount are 3+ for sure. I highly recommend this solution as it appeared to me to be the most stable and flexible.

Was exactly what I needed.

I used this adapter plate successfully for two separate jobs: first, to attach a Samsung 43-inch TV (200-mm Vesa pattern) to a medium-duty Huanuo single-monitor mount (75-/100-mm Vesa pattern, 19.8-lb capacity), and subsequently to attach a 43-inch Sony 'Bravia 3' TV (200-mm Vesa pattern) on a heavy-duty Huanuo monitor mount (75-/100-mm Vesa pattern, 26.48-lb capacity). In both instances, the adapter plate worked fine to bridge the difference in Vesa patterns. It was very helpful that the Mount Plus adapter plate came with a variety of nuts, bolts, and spacers to attach things together. For the first job, I needed no additional hardware because the Mount Plus 1056 came with everything I needed and did not have already. In the second instance, I had to add four optional washers to the mount bolts that attach the adapter plate to the TV. (The Samsung and Sony TVs require different-sized bolts for mounting.) The adapter plate did its job perfectly each time. Great job, Mount Plus! Pro tip: If you use this Mount Plus adapter plate, attach it to your swivel mount first, taking care to put the screw heads toward the TV so they sit flush without touching the TV. Tighten the four nuts so the adapter plate is fully attached to your swivel mount. Next (finally), attach the adapter plate to your TV. Don't over-tighten the bolts or they may damage your TV/monitor. If you reverse the order and try to attach the adapter plate to your TV/monitor in the first step (before attaching the adapter plate to your mount), you will have trouble tightening the bolts that attach the adapter to your swivel mount because they will spin in place as you try to tighten the nuts. You must have a screw driver and a small wrench or pair of pliers to tighten the bolts that attach this adapter plate to your swivel mount. Good luck!

i have a very old (and very tiny) samsung syncmaster b2230 that i love to death, but it only has 75x75mm vesa holes so that limits what mounts it can go on. i wanted to install it in my camp trailer, but the mount that came in it doesn't have the right holes.... this plate has ALL the holes! it works perfect for adapting between vesa sizes and comes with spacers to give everything enough clearances. i did have to go to the hardware store to get appropriate screws for my tv tho (the ones included were slightly too big) and also shorter bolts to give me enough clearance on the adaption, but that's not too big a deal. it does the job of holding my weird little tv in my camp trailer without having to replace my existing mount so im happy lol
