For an HDTV 42 or 46 inches, what is the difference in 60hz and 120hz?
Stuartdavi
I've done quite a bit of research and find answers that vary. Is the refresh rate of 120 so much better that its worth paying an extra 20 dollars for? Best Buy has a 46 inch LED with a refresh rate of 60hz for 440 dollars, while the 120hz is 460. Is it worth paying extra for?
Answer
60 hz is bad, you get a lot of pulldowns and motion blur. I don't recommend anything less than 120 hz.
Brands that I like the most and probably from best to least:
- (Top brands) Panasonic, Samsung, LG, Sony.
- (Top offbrands) Toshiba, Phillips, Vizio.
- When you buy a tv, make sure it good and has all the input and outputs that will be needed, also know that there are smart tv's.
Plasma >=< LED > LCD (LED is the same, but a upgrade from a LCD).
- Best picture quality = Plasma.
- Best audio quality = Plasma.
- Best energy consumption and environment friendly = LED.
- Best reliability = LED.
- (Newer plasma tv's fixed their burn in and use little less energy and a little better for bright rooms, the way plasma tv's are designed have no motion blur problems).
- (Newer led's use motion interpolation frames to up the frame rate of a video to fix motion blur, but can cause the soap opera effect, led's are good for bright rooms).
1920x1080 resolution or higher resolution is good (1920*1080=2,073,600 pixels).
- 1080 resolution is better than 720 resolution.
- Bigger tv's are better with 1080 than 720 (If the tv is around 32 inches or less I would go with 720, any bigger I would just want a 1080 especially for tv's that are over 42 inches).
- Farther you sit away from the tv means it's better to go with 1080 than 720 (If you watch more than 6 feet away from your tv, then I definitely would go with 1080).
Progressive scan > interlaced scan.
- Progressive scanning is a way of displaying, storing, or transmitting moving images in which all the lines of each frame are drawn at the same time.
- Interlaced scanning is a way of displaying, storing, or transmitting moving images in which all the odd lines of a frame is displayed first then all the even lines of a frame is displayed second.
- Example: 1080p > 1080i
- Example: 720p > 720i
- Example: 1080i > 720p (because more resolution is better for slower passed videos).
- Example: 720p > 1080i (because fast pass videos you be better off with progressive scan).
FPS = frames per second (of a video).
- Frame rate is how many individual images are displayed in a second. Think of a video as a fast moving flip book.
- NTSC countries use 30p or 60i fps.
- PAL countries use 24p/25p or 50i fps.
Hz = refresh rate (of a tv).
- Example: A tv with a 120hz refresh rate, meaning it refreshes the entire tv screen 120 times a second, some tv's use black light scanning.
- Many tv's allow viewers to have a computer program in the television digitally analyze concurrent frames and use the data to create intermediary frames. The insertion of these frames is called interpolation and they are what cause the soap opera effect by creating more fake frames (higher fps) in between the real frames to match the refresh rate of a tv.
- Many tv's allow viewers to turn off interpolation and force the television to repeat the same frame a number of times to match the refresh rate of a tv or use a 3:2 or 2:3 pulldown to match the refresh rate of a tv (a pull down will cause jittery screen also known as judder).
For NTSC countries:
- Example: To display 30 frames per second on a TV with a 120 hz refresh rate, each frame is repeated 4 times every 30th of a second.
For PAL countries:
- Example: To display 24 frames per second on a tv with a 120hz refresh rate, each frame is repeated 5 times every 24th of a second.
When the frame rates of a video cannot not divide into the refresh rate of a tv equally like the above examples, there is more math to it and there is 3:2 or 2:3 pull downs.
I am still new to 3d tv's, ill have to get into them as well and I am not really a fan of 3d tv's anyways.
- All I can say for now is I only like it for very slow moving scenes.
- When most movies start using a higher fps (EX: Lotr-hobbit with 48 fps), 3d will look better and less blurry during face pass scenes.
I am not really a fan of projectors either.
