Think you’re getting a 120Hz TV? Think again, you just might not be.
TV manufacturers claim refresh rates of anywhere from 60Hz to 240Hz, but how can you tell or know if you are truly getting what they claim? To start, lets establish a basic understanding of what these numbers and the measurement of Hertz are referring to. The number of Hertz refers to the refresh rate of the TV, or put more simply, the number of frames per second. The more frames per second the smoother the image looks. So 60Hz should be 60 frames per second, and 240Hz should be 240… but it’s not. Now let me drop a bomb:
There are no 240Hz TVs anymore
So you may be asking now how do all these TV manufacturers get away with advertising TVs that perform at 240Hz? They’re using words that technically mean nothing like “motion rates” or “effective refresh rates”. This falls in to a consumer beware or fine print type of explanation. Manufacturers are using tricks and loopholes to achieve a faux 240Hz rate. Two of the most common ways are BFI (black frame insertion) or creating and including an artificial frame from processing between 2 real frames. BFI is just as the acronym sounds;
A black frame is inserted between real frames to reduce the effect of motion blur. This take can take a TV from 60Hz to 120, or from 120Hz to 240 in theory, and is one example of how they get to claim 240Hz on their products.
The other method is to have an artificial frames inserted between real frames that the TV’s processor creates. While looking at two real video frames the processor creates an approximation of what in between frames look like and inserts them into the image. The problem that this process creates is that one manufacturer’s “240” could be a 120Hz TV, while another company’s “240” could be a 60Hz TV.
The final point that should be mentioned is that it is extremely rare that a budget TV will actually be 120Hz, keeping the truth in the saying too good to be true. If you’d like to find out more or to get the correct TVs in your home or business, schedule a consultation or give us a call today
