response time doesnt equal input lag, which will affect gaming much more.
without game mode/turned off processing, tv's can have up to 500ms input lag, vs around 30-50 max for a moni.
some vizio/sony/samsung/lg will do sub 100ms, but even the 30ms on the 43in UHD vizio (i tested), felt horrible compared to any monitor i had in the past 15y.,
and im not a mlg player that plays for cash prizes...
