On average, the total amount of light in the room is 50 percent of what's possible. You have a maximum light on and a minimum light off each half the time. If you increase how often you switch the light, so fast that you no longer see the light turn on and off, instead of a flashing light bulb, the room will just appear dimly lit. This is, in essence, how a plasma works. As a plasma TV engineer once told me and I mentioned in the refresh article , plasmas create light with time.
To create different shades of gray, the pixel is on or off for more often. Because our TV system is 60Hz or in some places, 50Hz , and each one of those cycles has to be a complete image -- for example 60 images per second or 50 -- a plasma has to switch the subpixels on and off very rapidly.
You could call these, to steal the modern parlance, Hz. Most plasmas now have While not completely accurate, you can sort of think of it as the TV creates 10 dark images that your brain combines into one, full-brightness, image, 60 times a second. Bottom line As we discussed in "What is refresh rate? Plasmas, by how they work, don't have an issue with motion blur. The Hz claim by all the current plasma TV manufacturers has to do with how the TVs create an image, but is not images per second.
So yes, Hz is a marketing term. However, because plasmas don't require faster refresh rates to produce a clear, sharp image, and this is technically how they work, it's fair to give Panasonic, LG, and Samsung a pass Got a question for Geoff? Send him an e-mail! No, he won't tell you which TV to buy.
You can also send him a message on Twitter: TechWriterGeoff. The TVs refresh rate, i. Okay, let me start by saying the refresh rate of the TV means little to nothing, yes it could give you smoother game play, but if your card can only display with 60 fps, the tv with refresh at Hz still but the card only runs the game at 60 fps.
That tv is excellent for gaming on a console or something that relies more on the display but even then, if you don't have hardware to support the frame-rate in the first place, your display is not going to boost that.
If that's to confusing let me know, Its really early in the morning right now but that's basically all there is to it. It has nothing to do with vsync, or how fast your graphics card is. There is no such thing as a hz TV, it is a manipulative marketing term that means nothing. It describes how often the pixels are lit per second, not the refresh rate of the display. The question was why are there only 60 fps on a hz TV, I know how vsync works. Create a personalised ads profile. Select personalised ads.
