Samsung now invades the computer monitor industry. Their recent LCD TV models are now capable of functioning as a computer monitor. With a Samsung LCD TV’s dual use, you will truly get your money’s worth. But how exactly do we use our LCD TV as a computer monitor?

Because LCD TVs do not suffer from burn-in problems, this is the best unit to replace a computer monitor. It promises clear and vivid images necessary for computer and video games. This is basically why LCD TVs attract more customers. Its versatility is truly something that gives value to the hard-earned money of its numerous buyers.

In reality, LCD TVs were derived from the computer monitor technology. Because LCD computer monitors have been a huge success, TV manufacturers decided to use the Liquid Crystal Display technology for home televisions. They almost have the same characteristics, only that LCD televisions have a more brilliant image resolution. They made it this way primarily to compete with the Plasma TV technology.

So if you are really eyeing a TV to be used as replacement for your computer monitor, better get the ones like the Samsung LCD TVs. You wouldn’t want to pay for AV inputs, a tuner, and other features you do not really need, right? Samsung LCD TVs have television models with 30-inch screens. The Samsung Ln37A450 and the Samsung La32A650 LCD TV are best choices for big screens that you can flaunt to your gaming fellows.

Most of the LCD TV brands, especially Samsung, have a VGA option that allows you to connect the LCD TV to your computer or even to a gaming system like Xbox and other gaming consoles. The one feature that you should never forget to look for when buying an LCD TV is the option for you to connect the TV to your personal computer.

Furthermore, you should also place your computer near your LCD TV. This will make everything else easier for you since you do not have to untie knots of cables and wires. You may also consider running the wires and cables through your walls for an organized look. It will also be a smooth transition between using your LCD as a computer monitor or as a home entertainment unit. If you know something about electronics, you can also set up a channel change or a switch that will shift you from a television screen to a computer or gaming monitor.

Choosing a television unit that has dual purpose is advantageous to every consumer. It saves you not only money but also space, and time and effort to change from one purpose to another. The screen is larger hence giving you a better contrasted and clearer picture. Indeed, LCD TV’s dual purpose is an exceptional feature every consumer should take advantage of.

Though both LCD and plasma displays come in the form of slim flat panel displays, yet from a technology perspective, these two flat panel displays process the image in a totally different manner.

Plasma uses a matrix of tiny gas plasma cells that are charged by precise electrical voltages to emit light and hence to create the picture image. Liquid Crystal Displays (LCD) panels – work by trapping a liquid crystal solution between two sheets of polarized glass. When an electric current is passed through the liquid crystals, they change the polarization of the light passing through them in response to the electric voltage – as a result of which, more or less light is able to pass through the polarized glass on the face of the display.

It is not the scope of this article to go into the actual details of how these different display technologies process the image – after all, what really matters is not what is going behind the screen but rather how these different display technologies perform as a television screen. At the same time, it is worth taking note that it is these same differences that give each of these display technologies, its strengths and weaknesses, and that therefore render one more suitable than the other in certain circumstances.

The list below highlights the most important differences between these two flat panel display technologies:

Size: For the time being, collision between plasma television and LCD TV occur in the 40 to 50 inch screen range. In reality, most LCD TVs top out at around 50 inch; larger screen sizes are also available though choice is still very much limited. This means that for anything larger than 50-inch, a plasma display is your only real option if what you are after is a direct-view TV system. On the other hand, at the smaller end of spectrum, namely 15″ to 36″ TVs, LCD is the way to go if what you want is something stylish and slim (at under 4-inches in depth).

Price: Here, the playing field is leveling at a fast rate. Up to very recent, plasma was the obvious choice for all screen sizes where collision between these two technologies occurs; this is no longer the case. In general, plasma still leads by a good margin only at the bigger screen sizes – 50-inch and upwards. At the smaller end (up to 44-inch), the price advantage when it comes to plasma vs LCD TV sets, starts to shift more towards LCD TVs.

Overall Picture Performance: Both plasma and the latest TFT-LCD flat panel displays are capable of producing excellent picture quality – with bright, crisp clear images. However, plasma flat panel displays are more suitable for basic home theater usage than LCD. The gas cell structure within a plasma display is such that there is no light leaking between adjacent cells (or pixels). This renders plasma displays capable of displaying deeper blacks – hence more suited to television and movie scenes where lots of dark and light content is shown simultaneously.

In comparison, the nature of LCD technology – where a backlight shines through the LCD layer – means that it is hard for it to achieve true blacks (i.e. true absence of light) as there is always some light leakage from adjacent pixels.

This does not mean that LCD panel s are not suitable as TV screens; today’s LCD TV sets make use of extreme high contrast panels that are capable of displaying very deep blacks, yet the latest plasma TV sets still have a slight edge.

Viewing-angle: What used to be a clear advantage for plasma displays is becoming more and more a non-issue especially with the latest generation of LCD televisions, however…

Do not always assume that viewing angle is no longer an issue when comparing plasma vs lcd TVs. The tendency – in particular with the cheaper LCD TV sets – is that the deterioration in picture quality with off-axis viewing is more accentuated with LCD than with plasma displays.

Image Retention and Burn-in: LCD TVs enjoys a technological advantage; they are not prone to burn-in, and image retention in LCD TVs – referred to as ‘image sticking’, is often completely reversible.

It is important to realize here that while burn-in in plasma displays and image sticking in LCD panels both lead to image retention, yet these are two completely different phenomena.

Burn-in is no longer much of a concern as it used to be with plasma televisions up to the recent past, especially for people with normal TV viewing requirements. Similarly, image sticking with LCD TVs is unlikely to take place under normal home entertainment use.

Viewing Distance: It seems that the pixel size and shape of an LCD panel renders a smoother picture than an equivalently sized plasma panel for the same pixel count.

This means that even if your viewing distance falls within the recommended distance of approximately twice the screen width for an HDTV, if this is less than at least nine feet, most probably you will be better off with an LCD TV.

Life-time: This is a non-issue with either technology. In fact, both plasma and LCD TV sets come with a quoted half-lifetime of around 60,000hrs. Even if this were just 30,000hrs, it would imply more than 14 years of use at 6 hours a day. And this when the average household in the US replaces the TV set every 7 years!

In other words, both plasma and LCD TV sets make use of extremely stable and reliable display technologies. As such, lifetime is more dependent upon manufacturer quality rather than upon display technology.

Response: Plasma TV sets carry an advantage here because even though LCD technology has improved to the extent that this is becoming less of an issue, yet LCD has still some way to go to achieve the same level of pixel response times as phosphor based displays.

Power Requirements: The advantage here goes to LCD panels as these consume less electricity. Estimates show that the use of LCD panels can result in some 30% power savings for the same screen size than plasma display.

Making the Choice

There is a market for both plasma and LCD displays – Plasma gives you a bigger screen for your dollar, deeper blacks, but then LCD do not suffer from burn-in and at the smaller end of the market (less than 40-inch screen size), LCD is your only way forward if you want something slim and stylish.

It is all a question of knowing what are the advantages and limitations of each with respect to your specific needs.

This article is an excerpt from a series of informative guides appearing on Practical-Home-Theater-Guide.COM under the Plasma and LCD TV sections of the site.

It covers only the very basics when it comes to compare plasma vs LCD TVs. There are a lot more considerations one has to take into account when selecting the display technology for a flat screen TV.

Because of their many advantages over traditional incandescent and fluorescent light bulbs, LED lights are poised to transform all forms of lighting. Selecting and purchasing LED lights requires buyers to learn new terminology and take into consideration factors that they don’t have to think about when buying traditional types of lighting. This brief article provides some basic background and purchasing considerations for first-time buyers of LED replacement lights.

As most people probably know by now, LED stands for light-emitting diode. LEDs are actually semiconductors (just like computer chips) that produce light more efficiently than traditional light sources. When electricity is passed through them, they emit energy in the form of light. These semiconductors are doped or injected with chemicals that determine their light color. LEDs convert the majority of energy passed through them to light, as opposed to incandescent bulbs that produce light as a by-product of being heated. For this reason, LEDs can be up to 90% more efficient than traditional household filament light bulbs.

LEDs have been widely used in as displays and indicator lights for nearly 40 years. Only recently, though, have engineers figured out how to make and mass-produce bright, white LEDs that can be used for general-purpose lighting. The high brightness and point-source characteristics of LEDs have made them the first choice for traffic lights and car tail lights, where visibility and dependability are essential.

So, what should you know when purchasing LED lights bulbs? The following list provides some basic guidelines:

1. While the initial cost per bulb is still high, the total lifetime cost of an LED light bulb is actually lower than that of equivalent incandescent and CFL bulbs. Taking into consideration energy costs as well as time and resources required to replace incandescent and CFL bulbs, an LED bulb that lasts 80,000 hours has a much lower lifetime cost.

2. LEDs are diverse, and – as unlucky purchasers are all too likely to find out the hard way – many types are useless for general lighting applications. The finest LED chips emit light with a Color Rendering Index (CRI) of 85%. The CRI, by the way, is a quantitative measure of the ability of a light source to reproduce the colors of various objects faithfully in comparison with an ideal or natural light source. LED light bulbs that use top-quality LEDs will last much longer than the novelty bulbs that many are selling and 60% longer than many competing bulbs that use inferior LEDs.

3. Contrary to what you may read some places, LEDs do generate heat, and this heat is actually the biggest problem that manufacturers face developing LED lighting applications. Manufacturers can now produce individual LED chips that are as bright as a 100-watt incandescent bulb, but these LEDs are practically useless for general lighting because installing them in a fixture creates ventilation problems that have not yet been solved. LEDs installed in fixtures and bulbs must be ventilated properly, and the better the chip, the more difficult it is to properly cool. There are many LED light bulbs on the market that do not take this into consideration and either use cheap chips so they don’t have to ventilate them, or do not ventilate their chips properly, significantly reducing its lifespan. While the typical LED light bulb is barely warm to the touch, if the chip is not properly ventilated, it can fail prematurely.

4. While LED light bulbs do last much longer than conventional bulbs, look closely at manufacturer claims for bulb life. The life-span of an LED light bulb should be its “half-life.” LED light bulbs do not burn out; rather, they gradually fade out. When a vendor says an LED bulb will last 80,000 hours, they mean that at that point, the chips will have reached 50% efficiency, and the bulb ought to be replaced. So, the bulb might last 100,000 hours or more, but its efficiency will have degraded greatly by that point. Using this 100,000-hour life as a selling point is therefore misleading. While LEDs don’t last forever, they will last 50-75 times longer than a comparable incandescent and 6-8 times longer than a CFL.

5. Searching the web, you will quickly find that the LED light bulb market is inundated with product. Many of these bulbs are relatively inexpensive (less than $20); however, you may find that many of these LED bulbs consist of questionable materials and dubious craftsmanship. Good LED light bulbs cost more than these cheap ones because they use high-quality chips with prices firmly set by reputable manufacturers like Cree. This means that though these LED light bulbs are more expensive, they are far superior.

6. LED light bulbs can’t be dimmed with traditional dimmers. LEDs require constant current to operate. Because of this, if a standard dimming method is applied, it will flicker at regular intervals, or worse, simply not work. In order to dim an LED light, a 0-10V dimming module is required in order to “trick” the LED into emitting less light. In theory, all LED lights are dimmable with this module.

7. When comparing LED light bulbs, you need to understand lumens. The lumen is a standard unit you can use to compare LED light bulbs to standard bulbs, such as incandescents and halogens. Roughly, a lumen is a measure of brightness. Lumen quantity is important, but maybe more important is lumen quality, i.e., luminous efficacy (lumen/Watt). Today’s quality LEDs have a luminous efficacy between 60-70 lumens/watt.

8. Color temperature and beam spread are the other key tools for comparing LED lights. Both color temperature and beam spread are measured in degrees. Color temperature refers to the color of the light emitted. In general, 3000 Kelvin is warm white (closer to infrared light) and 5000 Kelvin is cool white (closer to ultraviolet light). Cool white is brighter because it is the natural color of LED light, whereas chips that emit a warm white light require a phosphorous “filter” to “warm” the color temperature, thus reducing the chip’s brightness. Beam spread is the angle of the light that is being emitted. The lower the number, the more like a “spot” the light is.

The kitchen has always been one of the most important and one of the most used places in a household. There are always some delicate things present in a kitchen e.g. knives, cutters and other similar sharp things like these which can cause damage. One of these delicate things includes gas grills.

It is very essential that you keep your kitchen appliances covered properly for the safety of yourself and your family. The covers will also keep the appliances safe from any damages and rust. Most kitchen appliances are shock-proof and weather-proof these days but still necessary precautions are needed to be carried out just for the safety of people around.

What’s the use of Gas Grill Covers?

One of the most commonly asked questions that you will encounter on the internet is what are grill covers used for? Proper and regular maintenance and protection of delicate appliances like gas grills is very essential and the grill covers give you that protection. The effectiveness may decline if we do not cover them up properly. Here are a few reasons why you should buy grill covers.

1) Grill covers will keep your appliances safe from any external damage that can be caused by natural surroundings. Your grill will not get dirty very quickly and will require less maintenance. Also the covers save the grills from moisture which cause rust in metals. Most of the kitchen appliances are made up from metals especially grills.

2) Most of the gas grills are used for outdoor purposes and in open air environment, they are very likely to get moisture and in result prone to rustiness. They get directly exposed to sunlight and rain etc. If you get a cover, you will have complete protection against all of these threats.

3) With the addition of gas grill covers in your home appliances, you are ensuring that your appliances are long lasting and there is no decrease in their working and their efficiency. With the usage of these grill covers the appliance can be used for years and years to come without any decrease in quality.

So do buy a grill cover as it will only add to your protection and comfort.

The debate whether the charcoal or gas grills are better started in the ’60s, and there are no signs it will end soon. Charcoal gives meat a special flavor, but its use can be more complicated than a gas grill. Gas-grills are becoming more and more popular, and Weber is the best brand for barbeques: Weber-grills can be really expensive, so if you decide to buy a gas grill, it is wise to protect it with an appropriate Weber-Grill cover.

There are three series of gas style grills at Weber: Spirit is for the young people on a budget. The Genesis series are more advanced and stylish, and the top is the Summit series, featuring the latest technology available today. It is good to include in the budget for your Weber grill a genuine gas grill cover, especially if you will leave the equipment out in your backyard. This way snow and rain will not harm your grilling equipment.

Generic covers are much cheaper than a real Weber grill cover, but the difference in price shows in the quality: no-name covers are not made of the best materials. If you decide to buy a Weber cover, you should visit the Weber home page: at the Gas Grill Accessories section you can find the special covers for each grill series.

These grill protections are made of high quality vinyl, meaning that these covers are waterproof and very durable. The price of a Weber grill cover is between $40 and $60, and the manufacturer will usually deliver it within 3-5 business days. The price tag may seem expensive, but user testimonials make it clear that it is worth every penny.

A Weber gas grill cover fits tight, but it is easy to put on, and it never sticks on the grill under wet conditions. It can be folded and put under the grill, and because of its tough vinyl material, it can last for ages.

If you are in the market for a quality string trimmer, your options are much greater than they were just twenty years ago. When I was growing up these only options you have for trimmers, or weed whackers, were gas powered. No you have your choice between gas, battery powered, and electric powered line and string trimmers. How you will be using your trimmers will help guide you in making your purchasing decision. The common string trimmer review will remind you that gas powered trimmers are generally more powerful, and you don’t have to be restricted by being around a power source like those of the electric powered. The environmental impact however is not in favor of the gas powered trimmer, but the decision should ultimately be yours.

Battery operated string trimmers are great for home owners. In fact, a lot of urban or suburb home owners and renters choose this option over any other. These trimmers are great for light to medium use, which is perfect for the smaller yards of the suburbs. The bigger benefit is that you do not have to purchase fuel, and with the advanced batteries and battery chargers today it is easier than ever to keep powered. A string trimmer review can help you decide if this is the best weed eater for you to use. The electric trimmer is basically the same option as a battery powered option. The only difference in the two is that the electric trimmer still has the cord attached to it. Overall the same concept, but this is how the suppliers and retailers separate the two. These corded options are not as popular for obvious reasons, but for those with a small space to keep up then these options are ideal.

Reading a string trimmer review can help influence your buying decision. Seeing how other people have used and judged these products can help you make a more precise and confident decision. Trimmers are affordable and can be found most places locally and at online stores and retailers. Home improvement and warehouse style stores are the most common to use when shopping for your trimmer, but your location will decide. Shopping online can sometimes be beneficial to take advantage of some great savings, but the shipping and handling cost may end up costing you more in the end. No matter where you decide to buy your trimmer, always try to do a thorough job of shopping around first.
