Most of your high end TVs have a native 120Hz refresh rate. The Samsung Q8 and Q9 series even have freesync with it.
The issue is you are going to be looking at easily $1k for a TV with that refresh rate, I believe the Vizio P series has a 120Hz rate, and the Samsung's start at $2k. You would probably be able to buy a good monitor for less money at that refresh rate.
