You are wrong about TV Refresh rate and you are wrong about Vizio, HDTV's , many are capable of being overclocked to 120hz but I don't think mine is, I already looked into it.

I get screen tearing in my games, it could be my monitor though, I am gonna test it on my secondary 32 inch to see if i notice it with vsync off. I only notice it the most in star trek online moving my camera around really fast, other games I can see it sometimes but it isn't a huge issue, just a moderate issue in star trek online.
PC games I play are Star Trek Online and Planetside 2, the main ones I play now. Obviously an ultra wide gaming monitor 144hz and low input lag, FPS games benefit the most from this. Maybe I could get a Ultra wide for 3rd person/1st person shooters like The Division, Planetside 2 and Warhammer 40k:Eternal Crusade and possibly any other fps or MMO I will play. Basically I will use the Ultra wide for MMO's and 3rd person/1st person multiplayer games.
I will use my main screen for single player games, console games, computer and Star Trek Online.
The thing is, if I get a new better TV, like one of those Vizios or the coming R-Series.

It will for sure do 120hz on at least 1080p but you can increase that while still on 120hz buy using above 1080p resolutions on Nvidia DSR or AMD's equivalent.
Basically the only draw back is no FreeSync/GSync but the only game I mostly notice it in is star trek online so it isn't a big deal, even in STO I only really notice it by panning my camera view moderately fast or really fast, also depends where I am in the game.
The R will have at least 15ms in game mode, only 10 mor ms than the top 5ms gaming monitors, I don't think it is really noticeable, especially at a small difference like that.
I can also easily do 21:9 on a Native 16:9 screen and it looks exactly like it would on a 21:9 monitor with no bars using a custom resolution. Due to my preference for playing on bigger screens, I think I should just wait and see if the Vizio R ever hits retailers and not just requesting to buy them at Design centers.
