Un55B7000 Led - Finally An Lcd Competes With The Best Plasmas

The UN55B7000 LED is Samsung's current flagship model and is the successor to the LN55A950.

Picture Quality
A full LED backlit LCD offering a stunning 7 million:1 contrast separates the UN55B7000 LED from other LCDs by reaching deep into pitch black, formerly only possible with plasmas. Some LCDs turn off pixels to achieve inky blacks - ok for still pictures, but too slow to work with most video - basically a gimmick to inflate contrast numbers. The UN55B7000 LED however, masters the darkest blacks and brightest whites to produce a bold three dimensional effect or "pop." In a dark room, the UN55B7000 LED outperforms every LCD on the market, shy of the coveted pioneer plasmas. In a moderate to bright environment however, the UN55B7000 LED absolutely dominates.

The highly reflective screen can be annoying for those with unfortunately placed light sources or windows without blinds. A matte screen, as on the LG 55LH90, might be a better fit for some, but a matte screen diffuses the light causing the entire screen to lose those desirable inky blacks. I can't say one is better than the other, but for a TV that can produce such dark blacks, I think the glossy screen makes more sense.

Motion handling is the best of any LCD I've seen thanks to separate blur and judder adjustments and very few motion artifacts. Blu-ray discs will exhibit perfect cinema-like panning or, if you want, a more smooth and clear pan similar to a home video. My verizon fios hd occasionally shows judder when there should a smooth flow of movement. The UN55B7000 LED can help minimalize this, but it is not powerful enough to eliminate it and if set poorly, it can be made worse.

After some quick, basic calibration colors are vivid and mostly accurate. Noise and artifacts are very minimal on 720p and non existent on 1080p. Haloing (i.e. white text on black background cause background to lighten near text) is only visible rarely unless viewing from greater than 30° off center and increases in severity as viewing angle increases. Viewing from greater than 30° off center vertically or horizontally also causes a slight loss, contrast and color depth. Viewing from greater than 50° off causes a significant loss in contrast and color, creating a flat image and showing major haloing effects. The ideal viewing range is within 15° of center, though if centered vertically, image is barely degraded at all up to 30° off center. Ideal viewing distance is roughly 8 to 14 feet for 720p and 5 to 10 feet for 1080p, though don't take those numbers too seriously, you can obviously enjoy this TV from just about any distance. At 4 feet or less though, the 46" model is a better choice.

Ease of Use
The preset picture modes are all quite good for those who aren't picky and just want to watch their TV and the UN55B7000 LED does a decent job of assigning settings automatically based on the input. Of course, high-end buyers are more likely to calibrate sources to their liking or hire a pro. The TV will remember settings for dynamic, natural, standard and movie profiles for each source. That gives you a lot more flexibility than only having one or two, but it is complicated by a confusing lockout of various settings depending on how the source is identified. You can change the name of a source and find more or less settings available for adjustment, but how this works should be clearly documented. Also, there is a little lag when navigating menus, making constant adjustments of the many, many, many settings somewhat slow and annoying. The layout of the menus themselves and the amount of adjustments available is wonderful. The remote control works using RF so you don't have to point the remote at the TV. The remote is a little bulky, but offers all the buttons you'd want for operating the television easily. The scroll wheel is inaccurate for navigating menus and only really works as a directional pad.

Design
While, I prefer the touch of grey on some other Samsung, the small blue light on the bottom of the UN55B7000 LED is stylish, attractive and best of all, can be turned off. The bezel is attractive, thin, and highly glossy, but can be distracting when it picks up too many reflections. The 1.6" thick screen is amazing, but how often do you look at the side of your TV? The 61 lb. weight without stand is quite light for a 55" TV, but again how often will you move it? It does seem to use fairly little power and creates much less heat than a plasma TV. The swivel stand works well, also quite attractive with a brushed gunmetal finish.

Sound
I did not play around much with the sound as I use a 5.1 setup. I assume most people purchasing this TV will use external speakers, but the internal ones sounded just fine for what they are.

Comparisons
Competing models include the LG 55LH90/55LHZ, Toshiba 670u, Pioneer 500m/600m, Samsung 52B750/55B650/58B860, Sony xbr8 and Panasonic V10. My personal experience with display models showed the plasma screens to perform poorly in bright environments. Given the open layout and 20' ceilings of my living room, plus my wife's preference for at least dim lighting, this ruled out plasmas. The 58B860 in particular lacked the light output to produce bright enough whites in all but a pitch black environment. The 55LH90 seemed to be the closest competitor and much cheaper, with the xbr8 and 52B750 being close behind. The LH90 however, seemed to produce too many motion artifacts, couldn't deliver quite as much "pop," along with a slew of more minor negatives.

Misc.
Upgrading from a Syntax Olevia 37 hvs (matte screen LCD), this TV has truly blown me away. While the perfect (OLED?) TV is still out of reach, the UN55B7000 LED leaves little room for improvement. Input lag, a major concern for video gamers, runs under a tolerable 40ms according to my Rock Band 2 manual calibration with game mode turned on. With game mode off, the input lag increases to 140ms, which is easily noticeable. If running through a receiver, try component -> component instead of component -> HDMI for least lag. Game mode disables some processing but not the LED backlighting. The picture with game mode on even using a component connection (1080p) is incredible, though in need of some anti-aliasing on occasion. Turning off extra processing not disabled by game mode seems to have little effect on further decreasing lag, but I tend to turn them off. Auto motion is disabled in game mode, so expect some minor blur/ghosting.

The Samsung UN55B7000 also has a ethernet port for connecting to the internet and your home network (including DLNA or Anynet). A CD included with the TV helps you play media from your PC. Widgets will automatically update to display weather, sports, news, etc., but are a little slow and less convenient than popping open a laptop. Still, it's a good idea to plug in the TV to your router at least occasionally for firmware updates.

Conclusion
For those in the market for a 55" HDTV, the UN55B7000 LED is the most versatile and polished product out there. While a couple extremely high end plasmas beat out the UN55B7000 LED in a dark room, no other LCD performs as well and the plasmas quickly lose out as you increase ambient light. The attractive and practical design and feature rich menus complete this incredible package. While the 55LH90 is easy to recommend to those focused on price vs. performance or in love with matte screens, the UN55B7000 LED is clearly a step up and would make a remarkable addition to any loving home. Prices should come down as we head into the holiday season and onto the super bowl, however these seem to be selling as fast as they arrive for now.

UPDATE: After upgrading to firmware 1008, I experienced a sort of "crop circles" phenomenon caused by a malfunction in the smart LED backlighting. If you search online, you'll find several reports as it is a very widespread problem. I have posted a picture exhibiting the problem above. It can be fixed easily by turning your TV off and on again, but may reappear occasionally. I'm guessing it will be fixed by firmware update eventually, but no word from Samsung. Regardless, I'm still very pleased with my purchase. If the crop circles weren't so easy to fix, I'd probably be fairly upset with the problem. However, it was subtle enough only to notice against a still, uniform and light background.

2nd Update: Crop circles have not returned yet. I expect them to from time to time, but it seems more of a random thing than a problem that takes time to set in. Forum posters seem to have received word from Samsung that this issue is resolved and they are starting to roll out firmware updates (for now just as USB sticks to those reporting the problem)

As for calibration, I used Spears & Munsil High-Definition Benchmark Blu-ray Disc Edition [Blu-ray] to get my brightness, contrast and sharpness set properly. I came up with very similar numbers to what I've seen others post. Contrast 87, Brightness 47, Sharpness 30 (though I couldn't tell much difference fro 0 to 30). Setting the color space requires pro equipment, so I looked online for some numbers and they seemed to work better than default. Of course, it's a great idea to get your set calibrated by a pro because optimal color settings are not going to be the same between most UN55B7000 LED 's. I use dynamic profile for daytime, standard for game mode, natural for sports (and some other TV shows), and movie for everything else.

Internet stops working then starts all of a sudden?

My internet stops working when I have on my AC and TV, but when I take off either of those or both, it starts working again. Could this be because there isn't sufficient power getting to my wireless router? Can the internet be affect by how much electrical power is running through the wires?

I called the Time Warner Cable people and they said that it shouldn't be the case that the power affects it, but the guy I spoke to said he wasn't sure and that he would call a technical specialist and get back to me.

NOTES:
My computer, TV, and AC are all in separate wall outlets.
My AC is energy star LG single room 8000 BTU.
My computer is a small E-machines computer
My TV is a 50'' PLASMA
My router is LINKSYS broadband wireless-G 2.4 GHz
I live in a small apartment.

ANY help is greatly appreciated.

Have you tried switching them around just to see if it's a faulty wiring. or maybe your having some issues with your router signal, try moving it to an optimal location.

I hope this helps,

Plasma Cutter Compressor

Buying round grill grates?

I have a large tank. It is heavy plate tank from an 80 gallon air compressor. I'm wanting to convert it into a large upright gas smoker. I am wanting to set it up so I can install wire grates every three inches for items such as pork chops and ribs then remove grates for larger items. I need to know of a supplier that sells round grill grates by diameter. Replacement Weber grill grates is all I've found so far doing google searches. I'm looking for a company that sells a selection of sizes. I've just purchased the tank and havn't touched it with the plasma cutter yet to know the inside diameter of the tank.
Thanks for your help!

If you have a plasma cutter, why don't you just buy a sheet of expanded metal and cut the grates yourself. (A lot less expensive than buying pre made ones)

Since this won't be over direct heat, use a decent thickness of Stainless Steel.

UV Light - the Dangers and Benefits

When people think about UV light they usually imagine lying out on the beach, the sun shining high above, searing the sky and surf and slowly roasting them to a delectable lobster red. With the sun's force tempered by the Winter, people tend to forget about the dangers of UV, think that the cloud cover or lowered temperatures mean that their skin is safe, that there's no risk of burning or worse. This is wrong, and since each passing year brings about further erosion of the ozone layer's protection, it is especially important to learn about the realities of UV light, and how we can best protect ourselves from its pervasive threat.

What is UV light? Simply put, it's electromagnetic radiation with a wavelength that's shorter than that of visible light, and longer than x-rays. Visible light, UV rays, x-rays-all of these are just names for different wavelengths of electromagnetic rays. It's called ultra-violet because these frequencies are higher than the wavelengths that we humans identify as violet. There are five kinds of UV light, but the first two, Vacuum UV and Far UV are both completely absorbed by the atmosphere.

UVC is also rarely found on our planet due to its absorption by the atmosphere, but is sometimes used in germicidal lamps due to its ability to kill germs. UVC is absorbed by the outer, dead layers of our skin, and can cause corneal burns (commonly termed welders' flash) and snow blindness, a severe sunburn of the face. Though extremely painful, UVC burns usually clear up in a couple of days.

UVB is the most dangers of the commonly encountered forms of UV. It has enough energy to wreak photochemical havoc on our cellular DNA, but not enough to be absorbed by the atmosphere like UVC. UVB is needed by our skin to generate Vitamin D, but too much exposure can cause sunburn, cataracts and can lead to skin cancer. People who work outside are at the most risk of these dangers, and cloud cover is not enough protection to block UVB.

UVA is the most commonly found form of UV, and is responsible for the tanning effect we see in our skin after time spent in sunlight, and can cause sunburn if exposure is excessive. The atmosphere does very little to block this kind of UV, and it's needed to help generate Vitamin D. However, too much exposure can cause our skin to grow tough, hard, and wrinkled. It can also suppress the immune system and cause the creation of cataracts. Most tanning booths and phototherapy use this kind of UVA.

UV light has too much energy for us. While visible light does little to our skin, UV is to jazzed up. They create heat in the same way that rubbing your hands does-but instead of simply causing the molecules of our skin to vibrate they can actually knock electrons right out of the atoms, or cause molecules to split. This results in a change of the chemical structure of the molecule. This change is especially dangers to living organisms, as changing the composition of your DNA can lead to mutations, which can lead to cancer.

So be careful with exposure to the sun. Even during the winter it's likely that you're being exposed to UVA and UVB, and with skin cancer rates rocketing, it's critical that we take care of ourselves by reducing time spent in the sun and being sure to protect our skin from UV when we're out and about.

If you're interested in UV protection, take a look at a variety of UV sun blocks, hats, or
sun protective clothing
. Be sure that your sun block protects against both UVA and UVB, and that it remains effective for more than an hour or two, or invest in

Spark of light ?

What is it about the spark ( light) produced from an Arc Welder that we should not stare at the spark produced?

I think this is because, the arc produces many different wave lengths including UV and X rays, looking at it continuously may harm the ratina.

One more safety aspect - when we look at intense light, temporarily we may be blindfolded. Most of the welding is done at industrial / construction sites. Getting temporarily blind may cause accidents.

Why not Rent a Limousine for the Olympic Games

The Olympic Games 2012 is coming to the UK; London has hosted the Olympic Games two times in the last century. First was in 1908 and then in 1948 they were also going to host the Olympic Games in 1944 but it was cancelled due to World War II. London is the only city in the UK to have hosted the Olympic Games, and London has never hosted the winter Olympic Games. I gather as we never get snow in London and can you imagine them building a bobsleigh team around central London. As it would be history to watch London host the Olympic Games I suggest the best way to remember the event is to hire a chauffeur stretched limousine to take around London. There is a lot of benefit from hiring a limousine as you don't have to drive yourself, you can have more than 5 people sitting in the same vehicle at the same time, you can enjoy the complimentary bubbly and you can also act like a celebrity. What's more this is a once in a life time opportunity as the London Olympic Games may not come again for about 60 years and also this would be history and a story to tell all the younger generation.

Limousine companies know that it is going to be a once in a life time opportunity for customers to book their limousines for the London Olympic Games, because of this limousine companies have put the price up a bit and are taking bookings from now as it will become a very busy time and it will become very hard to have any last minute bookings.

Imagine the limousine arriving to take you the London Olympic Games, your chauffeur will be at your door in the morning with your limousine all ready with your complimentary bubbly chilling in the cooler with champagne glasses and strawberries with cream. You can listen to the radio as the limo drives off to get you to the arena. As you look thru the tinted window, you will see the public all making their way to the area either by car, bus, train or coach. This will make you feel extra special and may even feel like a celebrity.

Once you arrive at the arena the chauffeur will make an entrance with the stretched limousine and this can become a real head turner, the limos I suggest would be more suitable for this type of event are:

Hummer H2 limos

Ford Excursion 4x4 limousines

Lincoln Navigator limos

Audi Q7 limousines

Chrysler C300 baby Bentley limos

Jeep Expedition limousines

BMW X5 limos

Lincoln Millennium limousines

These limos hold between 8 -16 people and are inclusive with mirrored ceilings, fibre optic lights, mood lighting, T.V's, DVD's, privacy screen, mini bars, plasma screens, excellent sound systems and complimentary bubbly.

If these limos are not as big or you may want something a bit more memorable, here are a few ideas:

50 seater party bus limo

Pink Hummer H2 limousine

Pink Lincoln millennium limo

Fire engine limousine.

Why not have pink limo hire, stretch limo hire or hummer limo hire.
