There are several reasons. Now I am not saying you cannot game on a TV, but for some persons the tradeoffs are not acceptable.
Input lag - the amount of time it takes for the picture to be processed by the display device.
Pixel Density - The amount of pixels in a square in(cm) of screen realestate. Larger displays of the same resolution have a lower pixel density
Pixel response time - How long the acutal pixel takes to change state (motion blur) (generally also included as part of input lag)
Monitors for computers usually have less processing going on prior to displaying the picture and also are usually made with faster responding display's, thereby reducing input lag and motion blur. Also, monitors are made to be used at the close ranges that most pc users sit at (<3')(or the length of the persons arm). TV's are made to be view from a greater distance generally.
TLDR: it's more personal preference. Sudden death twitch shooters it would matter more for.
