@shiner LCD and OLED TV’s suffer from Motion Blur (“Herky Jerky”). Motion blur happens when an on screen object is moving fast or when the camera pans across the screen quickly. Sports in general see both these situations and that’s why most folks notice motion blur only when watching sports.
TV’s manufactures use different tricks to help compensate for motion blur. The main one used by all is the Refresh Rate. TV’s will have either a 60Hz, 120Hz, or 240Hz refresh rate. Standard definition (SD) TV’s have a 60Hz refresh rate, but High Definition (HD) TV’s can have any one of the three available rates. 120Hz is the bare minimum to compensate for motion blur, but many bargain HD TV’s all the way up to 60 inches only have a refresh rate of 60Hz. You basically get what you pay for. Very few TV’s have a 240Hz refresh rate and if you can find one they will probably break the bank.
One thing you have to watch out for is that some manufactures mislead consumers by using 120 and 240 on their packaging referring to something else other than refresh rate. You should pay close attention because the 120 and 240 will not be displayed with hertz (Hz). For example:
TruMotion 120 = 60Hz refresh rate
TruMotion 240 = 120Hz refresh rate
Image Motion 120 = 60Hz refresh rate
Image Motion 240 = 120Hz refresh rate
Motion Rate 120 = 60Hz refresh rate
Motion Rate 240 = 120Hz refresh rate
Most E-series and M Series under 60 inches = 60Hz refresh rate
Over 60 inches = 120Hz refresh rate
AquoMotion = As listed
Note - Sharp clearly differentiates between the listed Refresh Rate and the AquoMotion rate.
All TV’s = As listed
Frame Interpolation and Black Frame Insertion (BFI) are also used to compensate for motion blur. Terms like “TruMotion”, “Image Motion”, and “Motion Rate” refer to all the tricks combined in one basket. The manufactures say that those combined elements make, for example, a true 60Hz TV to behave like a 120Hz. It’s misleading, but that’s how they talk their way out of it. It’s always best to do your homework and stick to the reputable manufactures. Also,stay away from those bargin brands if you are stickler for video quality.
With all that said, you still have to consider the quality of the video stream. Garbage in equals garbage out.
