Normally in the US voltage for TVs is 120 volts at 60 Hz (hertz). Many countries use 220, 230 or 240 volts at 50 Hz. To understand hertz, you need to understand AC voltage. AC voltage cycles between a positive voltage and a negative voltage. It basically goes up to the peak voltage, then comes down to a negative voltage. It does not do this instantaneously, but instead, does it over time. If you were to graph this pattern, it would form a sin wave, which would slope up, then slope back down. It looks like the tilde on a keyboard "~". Each time this full cycle happens within 1 second, we call it a hertz. So our 60 Hz system would cycle from positive to negative 60 times a second. When you see Hz, it means cycles per second.
I am not a TV expert, but I think some manufacturers double the cycles per second to 120 Hz so that they can refresh the picture twice as fast in order to try to get rid of flicker and show a cleaner looking picture.

∙ 15y agoIt's an HD TV-set running at 120Hz - meaning it refreshes the entire screen 120 times a second.
This makes for a much more stable picture, reducing fatigue while watching - which can cause severe headaches when watching for an extended period of time.

What does 115 volts ac 60 hz mean?
Multiple-standard television sets, laptop computer power supplies, etc., are usually designed so that they can be used internationally. For example, my LED television set is rated at 100-240-V 50/60-Hz , which means that it can be connected to any supply voltage between those limits, and will work properly at either frequency. So, while '100-240-V 50/60-Hz' isn't the SAME as 120-V 60-Hz, it simply means that the device can be operated quite safely AT 120 V 60 Hz in North America, just as it can be operated quite safely at 230 V 50 Hz in Europe.
