Ä°s there any major difference between 400hz and 800hz?
Answer
Brands that I like the most and probably from best to least:
- Panasonic, Samsung, LG, Sony, Toshiba, Phillips.
- When you buy a tv, make sure it good and has all the input and outputs that will be needed.
Plasma >=< LED > LCD (LED is the same, but a upgrade from a LCD).
- Best picture quality = Plasma. (Plasma's are not good for bright rooms and the way plasma's are designed don't really need higher refresh rates to fix motion blur = plasma's have little to no motion blur). (LED's are good for bright rooms, but need higher refresh rates to get less motion blur, but higher refresh rates can cause a soap opera effect).
- Best audio quality = Plasma.
- Best energy consumption and environment friendly = LED.
- Best reliability = LED. (Plasma's can have burn in and don't last as long as LED's).
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.
- Another way is 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.
- Many vendors allow viewers to turn off interpolation and force the television to repeat the same frame a number of times or use a more traditional 3:2 or 2:3 pulldown. This creates a more cinematic effect.
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.
I am not really a fan of projectors either.

Do hertz matter on a smaller hdtv?
OneGuy
I plan on buying an HDTV (1080p 60hz) that's 22 inches from Amazon for about 200 bucks. I know that hertz matter for fast paced movement on television, but can you really notice the lack of hertz on a smaller tv (22 inches)? Thanks peeps.
Answer
- Top brands: Panasonic (Plasma) and Samsung (LED). (Plasma > LED > LCD). (LCD is going to be discontinued. A LCD tv uses cold cathode fluorescent lamps/CCFL backlights. A LED tv is a LCD tv, but with white or red, green, blue LEDs on the edge of the screen or a full array on the back of the screen).
= Plasma has best picture and audio quality (best response times, best viewing angle, best color quality, less/no motion blur for crisp/clear images because how it's refresh rate works). Newer Plasmas have improved their burn issues by using pixel shifting/scrolling. LCD/LED is best for bright rooms and have most light coming off the screen (Plasmas are not great for bright rooms because of screen glare and faded whites, but do great for dim or dark rooms). Newer Plasmas use less energy consumption and they are cheap to buy. LED are more popular because the manufacturers want to sell you their LED expensive tvs rather than their cheap Plasmas.
- I recommend 1920x1080p for movies, computer monitor/display, some tv shows, and some game console games and I recommend 1280x720p for some tv shows and some game console games. I recommend 40+ inches for movies and/or tv shows and 20-30 inches for computer monitor and 30-40+ inches for game console games.
- FPS (frames per second): Every video consists of a number of frames per second, think of a video as a fast moving flip book. NTSC countries use 60i or 30i FPS (newer stations use 30p or 60p FPS) for tv shows. PAL/SECAM countries use 50i or 25i FPS (newer stations use 25p or 50p FPS) for tv shows. Movies use 24p/25p/30p FPS (first movie to use 48p was LOTR: The Hobbit). Games use anywhere to 2 to 120 FPS (older games use lower FPS while newer games use higher FPS, usually they are up to 60 FPS today).
- TV refresh rate (measured in hz): Example, A tv with a refresh rate of 120 hz means it refreshes/flashes the entire screen 120 times a second.
- How do LED or LCD tv refresh rates work with the FPS of a video? (I recommend real/true 240hz refresh rate, some tv advertising may fool you by listing the fake interpolation or fake backlight scanning/dimming refresh rates).
- http://en.wikipedia.org/wiki/Motion_interpolation (Names of the new technologies for newer tv's at the link): Motion Interpolation or Motion Compensated Frame Interpolation (MCFI), is a form of video processing in which new fake frames are generated between existing ones to up the FPS of a video to reduce motion blur and/or for judder removal/judder adjustment. MCFI video processing may cause gamer input lag and/or artifacts such as the soap opera effect (may ruin the look of a video).
- Many tv's allow viewers to turn motion interpolation (MCFI) off. The tv repeats the frames a certain number of times to match the tv's refresh rate. Example; To display 24 frames per second on a tv with a 120 hz refresh rate, each frame is repeated 5 times every 24th of a second.
- But what happens if the FPS of a video does not match the refresh rate of the tv? Then you get a pulldown, a pulldown is what causes a jittery screen (aka judder) because the tv repeats the odd frames a different amount of times the tv repeats the even frames. Example; A 3:2 pulldown is post popular because it is needed to match a 24 fps video with a 60hz refresh rate tv, odd frames are repeated 3 times (12x3=36) and even frames are repated 2 times (12x2=24) and 36+24=60 FPS for a 60hz refresh rate tv.
How does Plasma tv refresh rates work with the FPS of a video?
- It will take each pixel in a frame and and repeat it a number of times based on the number of sub-field drives (SFD) the tv has with it's refresh rate. Example 1; (NTSC countries) 600hz sub-field drive/motion tv means 60hz FPS x 10 sub-fields per frame = 600hz refresh rate. Example 2; (PAL/SECAM countries) 600hz sub-field drive/motion tv means 50hz FPS x 12 sub-fields per frame = 600hz refresh rate.
- What is focused-field drive (FFD) on Neo-Plasmas? (Light switching speed = better colors and less motion blur) 2500hz focused field drive means sub-fields are virtually packed into 1/2500th of a second as a sharp impluse, creating crisp motion images even in very very fast movining images (FFD is defined as a inverse of light emission period t. 1/t = 1/0.4ms = 2,500 FFD). Regular sub-feild drives like 50 FPS x 12 sub-fields = 600 hz, light emission spreads as wide as 1 field time (1/60th sec) maximum which results in blurry images for very very fast moving images.
- Refresh rates on Plasmas work similar to LED/LCD tv's. These settings are usually automatic, but you can change them in the advanced picture settings, Example 1; 2D 24p FPS mode and choose refresh rates of 48hz/96hz or 30hz/60hz with pulldown (might use interpolation frames for pulldowns), Example 2; 3D mode and choose refresh rates of 96hz for 24 FPS or 100hz for 50 FPS or 120hz for 60 or 24 fps.ect Of course it has gamer mode or many other adjustments.
