Agreed, TVs just aren't the same as Computer Monitors. Dot Pitch is much worse, because they're designed to be viewed from much farther away. ie a 22" Monitor @ 1920x1080 vs a 32"+ TV @ 1920x1080. Same resolution, TV has larger pixels. They often have other things not optimal for PC gaming as well.

I use a 30" @ 2560x1600, won't ever go back to something smaller unless I have to.
