Looking for a 34-40 inch hd lcd, led, or plasma tv. I just want the clearest picture I can get for watching sports. Any suggestions on what tv?


Answer
LED is a just a form of LCD. What it does is allows the LCD to have better blacks, contrast, and colors. While not up to Plasma standards, its far beyond what normal LCD can do. But you pay a huge price premium for this feature. You can get a better plasma for less. Also, it doesn't solve the inherent motion blur problems of large sized LCDs.

LCD vs Plasma

LCD - is the everyman HDTV. It is cost effective, hence its popularity. It is also physically lighter than Plasma. It tends to draw less power than Plasmas as well (though good Plasmas are now competing with LCDs). It has a matte finish so is useful for rooms that have too much ambient light which can not be controlled. LCD whites are a bit brighter than Plasma whites (but how often do you crank your brightness to 100%). LCDs are considered better for gaming (but I don't think you'd be disappointed with gaming on a modern Plasma). LCDs are sharper in SD (think evening news instead of film); this isn't a good vs bad, its just a personal preference thing. LCDs also have a bit more muted colors; again this isn't good vs bad, its purely personal preference.

LCD technology has problems with fast motion though. That is why you see ones advertised with 120Hz or 240Hz refresh rates (100Hz and 200Hz in Europe). This does not come close to Plasma though. So they aren't as good for fast motion (sports and movies). The 240Hz ones are making good strides, but right now you're paying a HUGE premium for it.

LCDs are also not as strong with their ability to reproduce true blacks. Their blacks tend to be a bit grey and not a true black. LCDs with LED backlighting are coming out now though. These are finally starting to bring LCDs to the Plasma level in terms of blacks. However, like the 240Hz refresh rate, you must pay a large premium for this feature at the current time.

Plasma - they have better blacks (true black), contrast (greater ranges in blacks/whites so you get greys instead of clumps of black and white), and motion playback (their refresh rate is near instantaneous much like old CRTs were). Their overall image quality is better than that of an LCD. While prices on them are constantly dropping, they do demand a slight premium over LCDs of a similar category. The colors in Plasmas tend to have more "pop" to them; this isn't a good vs bad thing, its just personal preference. Also for SD viewing they are a bit "softer" (think more like film less like the evening news). This isn't a good vs bad thing, its personal preference. Most plasma owners get used to it and don't mind it.

Plasma's are glass though so are glossy. They can have reflection issues if you are in a room with lots of light that you can't control (you can't turn off the lights and you don't own any blinds). And good Plasma care would require you condition them. But its fairly simple to do. All you have to do is keep the brightness and contrast (picture) settings cranked way down for the first 100-200 hours, then optimize, and you'll have an amazing TV experience.

Plasma myth (1) - They experience burn-in. This is inaccurate, those days are gone. Just condition the gasses and then use it as normal and you're fine. Also, the better sets have built-in features to prevent this (on top of the technology just generally being better now than say 5 years ago).

Plasma myth (2) - They have short life spans. This is another inaccuracy. Most are now rated in the 60,000-100,000 hours range. At 8 hours a day 365 days a year that would mean a life of 20-30 years. So do you think you'll still want/own the same TV in 15 years, let alone 30?

Plasma myth (3) - They won't work in high altitude because of problems for the gasses. This is again no longer an issue. Current Plasmas can be purchased and used in mile high Denver, and above, so you'll be fine where ever you are (unless you're living in the Himalayas).

Plasma vs LCD - One important note though is TV size. In 42" and above you see and get the benefit of the Plasma advantages. But 40" and smaller and the benefits are diminishing. So if your needs are for a smaller television, LCD may be a wiser choice.

Plasma brands - Pioneer Kuro Elite is the best, followed by Pioneer Kuro. But these can cost as much as a small car. Panasonic Viera is the next best and is much more cost effective. The Vieras can give the Kuros a run for their money (they might not win, but they are no push over in quality). After that I would look to Samsung primarily as a Plasma option. There are also some LG models that have reviewed extremely well (but do your homework).

LCD brands - I would stick with Samsung, Sharp Aquos, and Sony (but only Sony if its on sale, otherwise it tends to be overpriced). Sony stopped manufacturing LCD panels, they now buy/use the same ones used in the Sharp Aquos sets. Samsung is a step above the rest if you go with the series 6 through 9 models. The series 4/5 are strong performers as well, but a bit better

Will I be able to adjust the refresh rate on my 600Hz Plasma?

Q. Hi, I'm getting a new LG 60" Plasma from Best Buy and I was wondering I know they're up to par with the refresh rate of gaming because i'm getting this because of the gaming...

I was wondering if i would be able to adjust the refresh rate on my plasma, and will i be able to use all the other modes other than "Game mode" without input lag... I just don't want a strong refresh rate where it will feel uncomfortable, but something smooth feeling and realistic feeling in gaming.

Also a little off topic i'm going for a 60" TV because i have a pretty big living room space, and was wondering if 18 or so ft. would be good for this size TV?

If i have anymore details to add i will do so down below, if any help would be great appreciated!

LG 60" Model No. 60PH6700
Actually I have the LG 2013 Model which is the 55LA6900 now that's LCD/LED and it has 120Hz which you can adjust the refreshh rate of TruMotion from 1-10 on any TV mode instead of Game Mode unfortunantly that's why I'm taking this back today, which of LG have great color and picture quality, i'm not saying Panasonic isn't good i've heard good thing's about both actually...

I'm wondering since this LCD/LED model now i have has the adjustments i'm assuming most brands keep they're adjustments the same so hoping maybe this LG Plasma all the adjustments as well for refresh rate....


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.
