Most TV's use LED PWM Dimming or Flicker which ruins motion clarity (increases blur and cause obvious double image ghosting at flicker rates below 480hz and are not multiples of the native refresh rate of 60hz) and makes some people suffer from health issues like headaches and/or eyestrain.

OLED and most Sony LCD TV's do not use LED PWM Dimming; some Sony LCD displays do regardless of the back-light setting, or when the back-light is set below a certain setting (8/50 and below for the X900E), but usually at a higher frequency than competitors.
Samsung sells a few displays such as the MU7000 which are Flicker/PWM Free as long as the back-light is not set below a certain setting (10/20 for the MU7000) while higher end models use PWM regardless of the back-light setting.
Many TV reviewers use the middle screen Leo Bodnar input lag measuring device at 1080p which includes the vertical, top-to-bottom LCD refresh rate and pixel response times. The top screen measurement is a truer measurement of the device-to-display delay or input lag, and is typically around 7-10ms lower than the middle screen measurement reviewers provide. For example, the typical middle screen measurement for monitors is around 10-12ms while the top screen measurement is between 2-4ms.
