Decent set. Just be aware it is a 60Hz set. |
I'm starting my research for BF. Why does 60Hz matter? chmanson, why red? |

By having a higher frequency and doing some other processing, TVs can have less flicker. Keep in mind that 480i/1080i has 30fps (frames per second) and 60 fields per second while 480p/720p/1080p has 60fps. So if you are updating the TV 120 times per second, you are either repeating frames/fields or doing some additional processing. All of that being said, I wouldn't hesitate to get a good deal on a 60Hz TV. |
IMO, 120hz doesn't matter. 120hz is only applicable in situations where the original content was recorded in a frame rate divisible by 120 (i.e. 24 fps hollywood movies). The 60hz or 120hz is the refresh rate of the screen, or how many times the image is drawn each second. If you are watching network television or playing a video game, 60hz works, because they are produced at either 30 or 60 frames per second, and the image gets drawn once or twice per second. The "problem" is when you have material at 24 frames per second. 60 ÷ 24 = 2.5, so you have a whole 1/2 a frame per second that must some how make it on the TV. This frame is usually dropped according to an algorithm, and you get the special hollywood movie "look". If you have a set that does 120hz refresh, 120 ÷ 24 = 5, therefore the original image gets written 5 times per second, with no frames dropped. This yields a (i'll admit) a bizarrely smooth image. I personally do not like it, as it makes blockbuster films look like they were filmed on a handy cam. That's just my opinion. Go to the store and take a look at a 120hz set running a movie. If the store has it set up to be running basic cable, you will not see any difference at all. |

Europe has 100Hz TVs because of the 50fps of PAL. 100 is not divisible by 24. |
69ragtop said: Yes, that is how they achieved it technically. 120hz's only use however is 24x5 |
printit said:I'm not coming up with the same deal. The Sears Sunday filler has the TV featured on the front as: it has been fixed. However, some people have other Sears promos to apply against this (like the eBay Gift Cards/with live Cash Back, other coupons, etc.) so it may still be a great deal for some. My apologies on the math error. |
Accepted although not required! Math major here. |
