It depends on what kind a game im playing. If i play something like dota, cs:go ( pvp in general ) i wont use tv because the important variables are response time and refresh rate. Modern TVs are good at response time and refresh rate but they are not even close to regular gaming monitor. But if i play games like rimworld, civ IV (turn based , can be paused or slow game play ) i could use TV because you dont need higher response time or refresh rate on whose games.
