Mount-It! LCD TV Wall Mount Bracket with Full Motion Swing Out Tilt and Swivel Articulating Arm for 13-42" Flat Screen Displays with VESA 75 to 200, 44lb Weight Capacity WITH 18" EXTENSION https://www.amazon.ca/dp/B00R8KPN4S/..._L2V3xb66HVTF0
I bought 2 of them one for bedroom other for above dinette. Just remember to buy shorter bolts to screw into wall and don't use the ones that come with it or they go right through the wall.
Also that link is for Amazon Canada but I'm sure you could find it in the states.
Oh and I have 2 24" flatscreens
