DRagor :
Human eye can only see the difference up to about 60 Hz. So unless you have superhuman sight, that 144 Hz gives you nothing IMO. If your TV is capable of 1080p display, I see no upgrade in this, going from bigger to smaller screen?
Anyway just go to any shop who has those monitors on exhibition and simply check with your own eyes if you see any difference.
This is ridiculous. After switching to 144hz I could never go back. You are better off going with a 24" screen regardless of refresh rate because the pixel density is going to be stretched out on any 1080p monitor that's larger than 24". 1080p looks worse on a 27" screen than it does on a 24". However, if you are going to buy a 144hz monitor you have to be sure that your hardware can put out 144 fps on the games that you play. If it cannot you are wasting your money. The other thing to look at is Freesync(AMD) and Gsync(NVIDIA) which is a feature that allows your monitor to match the FPS put out by your hardware, eliminating screen tearing problems when you can't output 144 fps all the time.
I'm guessing DRagor has never used a 144 hz screen in his life.
