Best monitors for online play?

I've got a budget of $200, $300 maybe but no more.
Also I play on a small Vizio TV, from like 2011 or so. Will a monitor make a big enough difference to where it's worth getting?

Here's a picture of what I have

If your TV is that old, chances are it’ll make a big enough difference that you’ll notice
