Posted by Parkzone Corsair in computer on August 30th, 2010
Light Crystal Display, the Clear Future of Monitors
The use of liquid crystals has been a breakthrough in monitor technology as well as in various display applications such as watches, televisions, and cellular phones among many others. The old CRT Monitors have been huge and bulky while the use of liquid crystals in every pixel has allowed a slim and sleeker look for monitors and display devices. LCD monitors are also electricity efficient, instead of having monitors that consumes a large amount of energy, LCD monitors require minimum energy consumption and it can also be made to run on batteries. That is why it is very versatile and can be used in many different mobile devices.
LCD monitors have a distinctive amount of pixels or fixed-pixel-array displays. In simpler terms, LCD monitors have a native resolution or a specific set of pixel density which in turn displays a specific resolution. The display resolution or pixel dimension tells the customers about the capability of the monitor to clearly display an image. All LCD monitors of the same sizes display the same resolution because all LCD monitors have native resolutions regardless of what brand it is. Putting a different resolution outside the native resolution will cause extrapolation; this causes multiple pixels to produce the same image causing a blurry display. Buyers need to be advised that buying large LCD monitors will actually lead to smaller image displays, this is one of a few cases wherein bigger is actually smaller.
Buying an LCD monitor is definitely a cost effective decision on the buyer’s part. The advantages that LCD monitors present far outweighs the very minor special considerations. Compared to cathode ray tube monitors or CRT’s, LCD monitors generate less radiation because there is no build-up of heat on its backside. It is very easy on the eyes and working with it is far less stressful and straining. It does not contain phosphorus and thus it will not cause any image burns during prolonged pauses. Aside from its modern and stylish look, LCD’s are very cheap and easy on the budget, it can also help lessen monthly electrical expenses since it consumes less energy during usage and while on stand-by. When buying LCD monitors choose the ones which are suitable for your needs in terms of display resolutions. Though it is quite appealing to have huge widescreen monitors, try to see how it looks when you open websites and documents so that you can check out if they are suitable for your needs. Ask for energy save devices that will add more savings from your bills.
What to Consider When Buying an LCD Monitor
A lot of clients drop by and have a barrage of queries about Liquid Crystal Display Monitors. A lot of clients do want to change their computer monitors; however, most of them are still quite hesitant to actually buy them. This is mostly because of the many aspects that you need to consider when buying an LCD monitor. Contrary to popular belief, LCD monitors are not expensive, in fact, it might even cost as much as when you first bought your old CRT monitor. It is also quite the money saver, so you really are getting quite a value for your money. In order to shed some light with regards to the amazing capabilities of LCD Monitors, here is a list of the most frequently asked questions about them and their answers.
What is native resolution?
The screen sizes for LCD monitors are expressed in pixels (e.g., 1024×768). CRT monitors have various numbers of pixels, but LCD monitors however have only a single value or number of pixels no matter what brand they are as long as they have the same sizes. This means that all LCD monitors have a designated resolution that clients should consider because if they want the best results, they will have to comply. Bigger LCD monitors will mean that the images displayed will be much smaller while smaller LCD monitors will actually display bigger images.
What is aspect ratio?
Aspect ratio is the ratio of the number of horizontal pixels to vertical pixels. Most monitors have aspect ratios of 4:3. The new widescreen LCD monitors however, have aspect ratios of up to 16:10, the high definition capabilities of LCD monitors can even have up to 16:9 while ultra wide monitors have a whopping 2:1 aspect ratio. This displays the far more extensive capabilities of an LCD monitor in terms of image clarity and definition.
What is Response time?
In order for the liquid crystals to display a color or an image in a specific area of the monitor, an electric current must pass through the LCD panels. The amount of time that it takes for the current to pass through the panels and the amount of time it takes the liquid crystals to alter it state, to turn on or turn off is called the response time. Response time does not only refer to the turning on or turning off of the monitor but also in displaying bright images as well as dark or black backgrounds. In general, LCD monitors’ response time is quite fast. The rising time or the time it takes to turn on is very fast but the falling time or the time it takes to turn off is a little bit slower that is why you will notice a short blur when images suddenly shift to bright streaks on the monitor with a dark background. This is a factor to consider especially when you are buying an LCD monitor for gaming.
What is viewing angle?
As the electric current runs through the LCD panel, the pixel displays the corresponding shade. The pixel however displays the shade directly in front of it towards the viewer seated directly in front of the monitor. This characteristic of the LCD monitor does not allow for clear images when the monitor is viewed on the side or any other angle other than directly in front of the monitor. Though it does require a straight on viewing, this characteristic is actually a sought after feature especially when clients would prefer more privacy with their screen. This is also a great reason why clients often times opt for dual widescreen monitors.
What is Brightness?
Brightness is the capability of the monitor to radiate light or display color. Most of the new monitors have the capability to be very bright. This allows the clients’ eyes to be most comfortable during prolonged use. New LCD monitors have advanced features when adjusting brightness. Adjusting the brightness depends on the clients’ personal choice. Having a monitor that is very bright can at times be helpful while at time this can also be bad especially when the ambient light is low. New LCD monitors can automatically adjust the brightness of the monitors through sensors and thus it can be quite advantageous to opt for them.
Is image quality important?
Definitely yes, buying LCD monitors is all about getting the best quality images and videos. Having the best images on your monitor together with having the ease that LCD monitors have on the eyes is by far one of the most enticing aspects when buying one. Since CRT monitors are quite limited in their image displays, LCD monitors offer clients precise, crisp and clear images because of its very wide range of aspect ratios and resolutions ranging from widescreens to high definition capabilities that display life like images. The image quality of LCD monitors is definitely one of the main reasons why clients fall in love at first sight for them.
Shopping tips in buying LCD monitors
LCD monitors are clearly the future of computer monitors and other display devices. Its cutting edge advantages and features are clearly what next generation monitors should be. When shopping for LCD monitors, try before you buy. Ask the technician to turn it on for you before you buy it. View the images on the screen and try opening web pages and documents on it that you routinely view or open at home and see if the image display is suitable for your eyes. Check on the brightness of the screen and try out different sizes. Each size displays a different resolution, so make sure that you find one that suits you best. If you need to replace old CRT’s then why not go all out and buy the best, try out High Definition LCD monitors and I’m sure you will be amazed at the results. You also need to consider screen real estate. Screen real estate is the amount of space that you can work with on your desktop. Other desktops do display bigger images but provide less screen real estate. You wouldn’t want to see applications and pages overcrowding your monitor right? Check screen real estate and see if you have enough space to view pages and applications without having to scroll through documents as if they were a mile long. If you definitely need a lot of space then I suggest you go for dual screens. Dual LCD monitor screens definitely make your desk look cool, it also creates a greater screen space for you to work on comfortably (I personally use a total of four LCD screens in my office). Dual LCD screens are definitely the way to go for all your multi-tasking needs. Look for monitors that have USB ports on the side. Having USB ports can increase efficiency and accessibility. This helps a lot especially when most of the ports are located below your desk in the CPU. You can also try out LCD monitors with built-in Speakers. The speakers can accentuate your existing audio devices and can possible create a sensor round sound atmosphere. In shopping for LCD monitors, always try out the newest models with the most accessories and features.

3 Things to Know Before You Buy Digital Memory
Posted by Parkzone Corsair in Business on August 5th, 2010
Buying digital memory should be easy, but there are pitfalls waiting to swallow your time and money. Avoid disaster by following these three steps before you buy.
1. Research your products
Don’t buy on price alone, because what seems like a great deal can turn out to be a nightmare. Reports are growing of fraudulent and fake digital memory products turning up on ebay and other market places. These fake goods are sold as being high capacity – frequently 16gb or more – but the truth is that they hold little more than 2gb of memory.
Innocent buyers, thrilled to be getting a bargain, are left with corrupted files and lost memory when the re-programmed memory device they bought fails to live up to the promise. These cards are incapable of holding anything like the amount they claim, so the excess data gets dumped or heavily compromised.
Research either in shops or on manufacturer websites so that you can recognise genuine products. Kingston is just one memory manufacturer which colour codes its goods according to capacity. Seen a green Kingston keydrive for sale with 16gb capacity? It’s undoubtedly a fake – a 2gb device re-programmed and re-labelled – the true Kingston 16gb key drive is crimson. Some of these disreputable sellers sell memory in capacities not even offered by the brand they’re supposedly offering. Others offer non-branded goods claiming to be a higher capacity than they are. A brilliant source of data on this issue is http://fightflashfraud.wordpress.com/ the Fight Flash Fraud blog.
2. Research the seller
Whether you choose to buy from ebay or a known online shop, it pays to read the reviews. The beauty of ebay is that buyer feedback soon shows up problems with products. The downside? When it comes to buying digital memory from ebay, few buyers think to test their new device on arrival. The products arrives on time looking good, so the customer leaves positive feedback without realising that they’ve been conned.
The answer is to really scan the feedback, looking for signs that any other buyers have had problems with the goods. At any sign of fake products, look elsewhere. It’s no bargain. And ebay sellers who keep their feedback private? When it comes to buying digital memory, avoid them totally. These type of sales have no need to remain confidential – the seller is hiding something.
If you buy from an online shop, you can check out review sites. You may need to make an allowance for the fact that they are more popular with the grumblers than the praisers. A seller’s response to questions is often a good way of judging their service – and how long they have been in business. A poorly-run business will not last long in today’s economic climate. The About Us on a website should give you a good feel, as should the amount of contact info.
3. Identify your need.
This is where you should be looking when trying to save money. Why cough up for a 16gb sd card if you actually only need a 4gb one, or even a few 2gb cards? Bigger is not always better. With technology moving apace and costs tumbling all the time, you may find that the cost of a high capacity memory card has halved long before you’ve had time to fill the one you bought at high cost.
You can easily fill a 2gb memory card with more than 600 images, possibly double that, depending on megapixel size. Even professional photographers rarely take that many images in one session, so the amateur snapper probably doesn’t need a 16gb card in his camera, unless he films a lot of high resolution video.
It might be convenient having everything in one place, but you probably don’t want to store all the photos you’ve ever taken on one SD card. It makes more sense to download images regularly and store them securely. You can replace a lost or stolen camera, but if you failed to download your images simply because you had a high capacity card, your images will be lost forever.
Don’t waste your money either on single high capacity key drives when you could grab a bargain with a multipack of lower capacity keydrives. A very handy key drive is the Dane-Elec zLight 2gb. They come in five-coloured multipacks, allowing you to easily separate your photos from your music or data files. If you’re backing your hard drive, you may well need a weighty drive, but otherwise you could be wasting your money.
So, the conclusion? Think before you buy. Don’t just make a grab for the first low-cost digital memory offer you see. Doing some research only takes a few minutes and can be the difference between success or disappointment.
