A:Answer “The Beast Heavy Duty TV Wall Mount With Long Extension Arms” will work! Had this TV, TCL 98” installed today at my house and I purchased the above mount from Mount-It.com, also available at Home Depot and shipping was fast. It cost $199.99, holds 275 pounds, has a 10 year warranty and compatible with TV”S up to 800x600 so that includes the 500x600. I just learned all this recently. Our installers were VERY impressed with The Beast said it was the best they’ve ever seen, easy to install, extremely sturdy and it worked beautifully. Our new 98” is hanging right now and will extend well over 30” front the wall. I purchased the Kanto mount from Best Buy for this 98” TV & I was told it would work, But I contacted Kanto asking if their Kanto PMX700 is compatIble with TCL 98” TV and they responded, “this TCL 98” TV is not compatible with ANY OF OUR Kanto TV Mounts.”. That’s when I researched and found THE BEAST! AND WE ARE SO THANKFUL WE DID! I hope this helps someone, Thanks
