Why do Plasma TV's look so dim in stores?




.


I'd like to get a new TV... I've been wanting one for months. I read from online reviews that Plasma's look the best, but when I go to a store, like Best Buy or Wal-Mart, Plasma's look dim. The LED TV's next to them look brightly lit, better, etc.

What's the deal? How do Plasma TV's look best... when they're so dimly lit up? Or do LED's actually look better?



Answer
Big box stores are very brightly lit, which tends to wash out the screens of any TVs on display. LCD (both LED and CCFL, the two methods of backlighting LCD screens) HDTV adjustments include not only "Brightness" and "Contrast", but "Backlight" level. This last is always cranked as high as it will go on LCD screens to combat the store's lighting. Plasma displays produce pictures more like a CRT does (Cathode Ray Tube) with a fluorescent-like gas producing light which hits phosphors and while there are Brightness and Contrast controls, the overall picture brightness level is limited. This is not as apparent in normal viewing conditions.
Speaking of limiting, many plasma displays have a feature called ABL (Auto Brightness Limiter) designed to limit brightness so as not to cause damage to the display. This does cause some artifacts that some object to when very white scenes dim a bit.
Further, many plasma displays have a glass screen which is shiny, as opposed to LED and CCFL LCDs that have a matte surface, which cuts down on glare (another thing you see a lot in showrooms but less in typical viewing environments).
Many people swear plasmas look better overall, but there's not doubt they use more power, are not as bright as LCDs can be, and are a little more fragile (although the burn-in issue that was a concern has been largely eliminated).
However, IMHO, LED lit LCDs (either edge lit providing thinner displays or back-lit for more effective local dimming - a whole other discussion) are a better, newer technology and a better choice - but beware - 4K is coming!

Best Flat Screen TV out there?




Cool heads


I am curious what Flat Screen TV has the best quality, and durability... looking for something in the price range of 1k, and perhaps 37inch or 42 inch???

and where is the best place to shop for one???



Answer
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 beating 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.

It has problems with fast motion though. That is why you see ones advertised with 120Hz refresh rates. This does not come close to Plasma though. So they aren't as good for fast motion (sports and movies). The new 240Hz ones with LED backlighting are making good strides, but right now you're paying a HUGE premium for those features.

Plasma - they have better blacks, contrast, and motion blur. They are better TVs, but you often do have to pay a bit of premium for them. Images look smoother. They have greater ranges in blacks/whites so you get greys instead of clumps of black and white. The colors in Plasmas tend to have more "pop" to them; this isn't a good vs bad thing, its just personal preference. Plasmas are great for fast motion (sports and action movies).

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). 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.

They do have to be conditioned. The gasses of new Plasmas need to be conditioned. All you have to do is keep the brightness/contrast 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 BS, 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 more BS. You can leave your Plasma on 24/7 for 34 years before killing it. 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 you're going way smaller than LCD is likely the better option.

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. Then I would go with Samsung. For your budget, the Panasonic TH-42PX80 or PZ80 would likely be the best quality you'll get. And those are some amazing sets.

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 6, 7, or 9 series models. In your budget, maybe look at Sharp Aquos LC-42D65u or perhaps a Samsung LN40A630 (now been replaced by a new model, so if you can find this one on liquidation ought to fall within your budget).

What is the best reasonably priced LCD TV?

led tv matte screen image
Q. A TV under $2000 and not a power hog? Exclude sharp, or DLP type tvs. What is the best way to test or determine whether for instance like the differences between the tvs for different refresh rates say 60hz, 120hz or 240hz etc? What are your experiences with your tv that you have just purchased did you get a good deal and where did you find the deal?


Answer
Look into a Panasonic plasma. You can find up to a 50" for under $2000. LCD's are not worth the money. Pretty much any plasma you'll find out on the market now will out-perform any LCD you put it up against, even an LED. And dont be scared off by what some people may say about plasma's. Most of their information is out-dated. Burn-in is no longer an issue. You'd have to be TRYING to burn-in an image for it to even be an issue, even then its only temporary. Any burn-in will correct itself after normal viewing on the TV. Image retention on any LCD is permanent. Although its extremely difficult on either type of set. LCD's have poor response times which lead to motion-blur. Most newer plasma's have .001ms response times(almost instantaneous) where the best LCD response time I've ever seen is 2.4ms, with most LCD's having between 4-6ms response times. LCD's have poor viewing angles(when you move off center you lose picture quality and color) when comparing it to any plasma. And contrast and color accuracy are far better on any plasma. "Well what about glare?" loads of people would say. The only LCD's which actually combat glare have extremely matte finish screens. The color on those sets are horrible. It's as though youre looking at the picture through a foggy window, the colors extremely dull and faded. LCD's with the best color have a gloss on their screen which give equal amounts, if not more, glare than a plasma. As for power consumption, plasmas do use more power, but we're talking about $1 more than an equal size LCD. You can use the money you saved getting a plasma towards that $12 a year extra you'd be using. In the end, look up any LCD v Plasma rating that actually gives you a winner(not just state the differences) and you'll find plasma's blow LCD's out of the water. Plasma= more TV for less money.

Would you recommend a plasma or an LCD flat screen?

How to fix the back light on a laptop?

led tv matte screen
 on Flat Screen Tvs At Amazoncom - Home Design Ideas
led tv matte screen image



John


I had a co-worker come up to me today and ask me if I could help him fix a back light on a laptop. I don't own a laptop so I had no idea about the problem he was facing. He described it, if you held a flashlight at the back of the screen you could see it.

He said it would cost 200 dollars at best buy to get fixed and he said he wanted to do it himself.

Anybody have suggestions I can pass along to him?



Answer
Best Buy labor rates are high. There are repair shops that do the job with $35 to $85 in labor.
There are several here in Las Vegas, some of which work by mail also. They are easy to find on the internet with google.

Images of LCD screen are transparent color dots with light shining behind. That light can be either LED which all laptops (and most TVs) use or the older CCFL fluorescent. The fluorescents are no longer produced and went up in price and there are converter kits. When he says he shined a flashlight onto the screen, he means he can then see the images are there, but the backlight is out. There are two issues possible. The LEDs have a driver card and the CCFL has an inverter card. The electronic card could have died. It also could be the bulbs and that is more common in the CCFL. It could also be a bad connection in the cabling or connectors.

You first need the exact model of the laptop to find out if it is LED or CCFL and find the replacement screen. Then it is a choice of whether to find the driver or inverter card on ebay or Amazon or to try replacing the screen first or both as a pair.

There are sellers on ebay and amazon also
If it is an LED screen, it usually includes the driver card and is typically about $70
The exact size, connector location, pixel counts have to match. They can be matte, gloss with anti-reflective coat, or gloss without coating.
In CCFL, the inverter card may be included or not, and it is cheaper to get a converter kit and appropriate LED screen than a CCFL one.

Unless able to test things, normally you fix by replacing parts.
Instructions are available on youtube for many laptops. It is about a 20 minute job for most people.

adding: The bulbs are not typically replaced.

what is the best flat screen,plasma,lcd tv does ps2 works best on?







Which tv does brand and model or what not can make the ps2 fit the whole hdtv because it wont fit mine im willing to go buy one in talking about it wont fit the aspect ratio.


Answer
The LG LW5600 series evinced excellent color in bright and dark areas, along with relatively deep black levels and even screen uniformity for an edge-lit LED-based LCD TV. Its matte screen works well in bright rooms. The Smart TV Internet portal is well-designed with a solid selection of streaming services, and LG includes a Wi-Fi dongle. The secondary motion-sensitive remote provides a cool, easy-to-use control option. Passive 3D on this TV has minimal crosstalk, is brighter than active, and LG includes four pairs of lightweight, nonpowered glasses
