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.
It'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.
Has 3x HDMI inputs, 120 Hz refresh rate (no ghosting), multi-system, 120-240 V
A standard 60 Hz TV cannot be increased to 120 or 240 Hz due to limitations with the equipment. These higher refresh rate televisions are specifically built this way from the factory and offer no upgrade options for older models.
If the power from a wall socket is 120 V and 60 HZ, you can. Anything else will burn out the TV.
There could be a few reasons on why the motion blur is bad on a 120 HZ TV. I would take it to a repair shop and see what they say about the TV.
The Orion 46 Inch TV Model SLED4668W is a 60HZ television. The price range for this television is between $400.00 to $500.00.
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.
In my opinion some of the best brands for LED TVs that are at least 55 inches are; Samsung UN55B7000 55-Inch 1080p 120 Hz LED HDTV and Samsung UN55B8000 55-Inch 1080p 240 Hz LED HDTV.
600. Absolutely.
Yes !
The Samsung is better.
hz or more correctly Hz is a unit of frequency meaning cycles per secondhtz is a common misspelling of Hz
It is if you watch sports.
