Your question was answered previously by Kanto support to another buyer regarding 200x200 for Kanto Model:TTS100: "Your TV has a compatible 200x200 VESA, should work well!"
I have this Kanto Model:TTS100 stand and it works very well. Very sturdy. No worries about it tipping over. I first had an LG 55" LCD (400X400) mounted on it. Now using the stand with a Hisense 55" 4k tv. (200X300) Setup is very easy...helps to have another person to assist with the lifting...I didn't....My hernia now has a hernia!
