You might not have noticed this issue, but many do. The short version is that by increasing the number of frames (or another method we'll talk about below), there's a reduction in the apparent blurring of moving objects. You can read more about the what and why in What is refresh rate?. The main reason is to reduce motion blur. So if 60 is enough for nearly all modern content, where does 120Hz come from? A 120Hz model creates it, converting the incoming signal to that 120Hz. There are no 120fps movies or TV shows available. Unless you have a computer or an Xbox One, nothing you have will put out more than 60Hz.
REAL OR FAKE 4K ALITA 1080P
Getting different framerates to fit into 60 is a whole other topic, which you can conveniently read about here: 1080i and 1080p are the same resolution.įor now the important part to take away is that the stuff you watch matches, or is less than, the 60Hz of a normal TV. Some TV shows are 60 half-frames per second, or essentially 30 frames per second, while nearly all movies are 24 frames per second. Nearly all current TV content is 60 frames per second, or far less. For this discussion, you can think of 60Hz as 60 frames of video per second.
Matching the 60Hz of our electricity, TVs historically had a 60Hz refresh rate. How fast those image are shown - their frequency - is measured in hertz (Hz). TV is a series of still images shown fast enough that your brain thinks there's motion. If you live in Australia or the UK, just read "100Hz" and "50Hz" when you read 120 or 60. In the US, our electricity is 60Hz, and our TV system is based around that rate. The weird part is, the way manufacturers are coming up with these fake numbers isn't always total bantha guano. And even higher-end TVs, like Samsung's QLEDs and Vizio's P series, use numbers higher than 120Hz to seem even better with motion. On the other hand, true 120Hz makes a TV more expensive to manufacture, so it's rarely found in budget or even midrange TVs.
