Quality of 60hz and is 120hz neccessary?



  • Question about the difference and need for 120hz. Looking to buy a 4k tv this upcoming holidays and I am hesitant on the 60hz versions. Is there a huge difference with a 120hz version?

    How is upscaling and watching content off Netflix?



  • Hello Kaygen, Simply put, yes there is a difference between the two. Most 4K TVs come with either 60, 120 or sometimes 240Hz native refresh rates and in order to make their models look better, the majority of manufacturers also add in an artificial frame interpolation bump (each brand calls their version by a different name) which doubles the actual native refresh rate, at least on paper. Thus, if we're talking about, say, an LG 4K model, it might have an actual native refresh rate of 60Hz and a "TruMotion" rate of 120Hz, or a native refresh rate of 120Hz and a "TruMotion rate of 240Hz.. However, the extra 60Hz (or 120Hz) are basically fake and work as more of a marketing gimmick then a real benefit to the TV. In simple terms, if you want a 4K TV that's good for sportscasts and other fast action native 4K content, go for higher native refresh rate wherever possible.

    The problem with this is that many manufacturers sort of try to hide their native refresh rates, but you can usually easily guess native refresh by looking at the "enchanced motion" rate. (Called "TruMotion" for LG TVs, "MotionFlow" for Sony, "Motion Rate" for Samsung TVs and "Backlight Scan" for Panasonic models).

    In the overwhelming majority of newer 4K TVs, a rate of 120 means a native refresh of 60Hz and a rate of 240 means a native refresh of 120Hz and any number above these means either a native rate of 120 or 240Hz. Any stated motion rate that goes above 240 is useless and doing nothing for the TV anyhow. It really disguises a native rate of 120 or 240Hz. Fortunately, TV makers have now mostly stopped exaggerating their motion rates beyond the 240Hz limit.
