How To Choose A Monitor For Your Computer


Tips for Choosing a monitor. Best monitor for your PC.


We think that once you have decided to buy a monitor, then you have an idea of why you need this device, and in what area you will use it. Play games or to design, build graphs or typing, to train or attend a different page on the Internet. Let us say at once - modern monitor, no matter what you choose, will do an excellent job with the tasks that you put in front of him. "What's the difference? - You ask - because on the counter a lot of models with different prices and features. " We will get back to you - the difference is still there.
  • First, the type of matrix - perhaps the most important feature! The type of matrix depends on many things: contrast, brightness, response, viewing angles.
  • Second, the diagonal and interfaces connected to a PC (DVI, VGA, HDMI).
  • Third, the design (do not laugh, it is often the design you overpay for a good part of the cost of the monitor).
  • And finally - the manufacturer. The more known the firm, the more expensive monitor.

I think that now the first thing you should pay your attention to when buying a monitor, it is the type of matrix. But this is where you will be and for a surprise! The market is mainly represented by only one type of «TN + film», and monitors other types of matrices are extremely rare and the price they are much higher than their «TN» fellows. Accordingly, the characteristics of monitors about the same. What do we have - the most important characteristic is known, and what monitor to choose - no. Our advice: Decide on design, price, firm, ask the dealer what manufacturer the best service in town, and then ask the monitor. If an image of them suits you, feel free to take - do not lose. And do not worry - despite all the shortcomings of the matrix "TN", it works fine for most jobs.

If, however, you decide to find out in more detail the types of matrices and choose the one that will best meet your needs, we give a brief overview of the main types:

1. TN + film (Twisted Nematic + film), part of the "+ film" means an additional layer of film that is used to increase the viewing angle, because now it is used in monitors everywhere, the name of the type of matrix is often shortened to just "TN".

This is the cheapest and most popular type of matrix. The relatively low response time and power consumption of the drawbacks of the most important are inaccurate color (due to the use of only 6 bits per color channel, and missing shades are obtained by mixing the different ways available), low contrast and relatively small viewing angles (especially vertical). Also, in case of failure or sabpikseley pixels on these matrices (so-called. "Broken" pixels) in most cases they remain constantly lit ("burning").

2. IPS (In-Plane Switching). All matrices with technology In-Plane Switching, originally characterized by the best of all types of matrices viewing angles and color reproduction. Contrast and response time are highly dependent on the specific implementation of this technology, it may be noted that the IPS matrix have an average response time of more than TN, and worse contrast than the best representatives * VA matrices. Defective pixel or sabpiksel on these matrices always remains in the extinguished state.

At present there are the following types of matrices that can be considered as derived from IPS: 
  • 1/2. S-IPS - proposed in the 1998 version of the IPS with a reduced response time. 
  • 2.2. AS-IPS - Technology Advanced Super IPS; was developed in 2002. In fact, is a S-IPS with improved (to the level of S-PVA) contrast. 
  • 2.3. A-TW-IPS - Advanced True White IPS. Is an S-IPS panel with a color filter True White («real white") to give the white colors more realistic and wide gamut. This type of matrix is used to create professional monitors for use in photo labs and / or publishers. 
  • 2.4. H-IPS - The latest version IPS, which appeared at the end of 2006, characterized by a greater contrast and more uniform visual surface of the screen. Largely devoid of stray light - for example, there is no "firm" purple hue when viewed on the screen with large angles, but it took a bit of sacrifice proper angles. 
  • Currently monitors of technology-based IPS monitors are the most popular on the matrices NEC LG, Philipps
  • 3. * VA (Vertical Alignment) The first matrix of this type, which is called "VA" was developed by Fujitsu. In the future, these matrices improved and made a number of companies. They are characterized as a compromise for most of the features (including the cost and power consumption) between TN and IPS, as well as the latter left the faulty pixel or sabpiksel in the extinguished state. Their main advantage is the high contrast, with good color reproduction (especially the latest version), but in contrast to the IPS has a negative feature, which is manifested in the failure of shadow detail at normal look and color balance of the dependence on the angle of view.
  • 3.1. MVA - Multi-domain Vertical Alignment. The first widely spread type of matrix of this family 
  • 3.2. PVA (Patterned Vertical Alignment) - * VA technology development, proposed by Samsung, is characterized primarily by increasing the contrast of the image. 
  • 3.3. S - PVA (Super-PVA) from Samsung, 
  • 3.4. S - MVA (Super MVA) from Chi Mei Optoelectronics, 
  • 03.05. P-MVA, A-MVA (Advanced MVA) from AU Optronics.

Advised to pay attention to the following points:
  1. Prices for monitors in September and October of each year are creeping up. This is explained by the fact that in this time of year pupils and students acquire massive computers. Therefore, if we decide to buy a monitor, it is better to do it in the spring and summer.
  2. Visitors to our site have the opportunity to buy the best monitor for your PC with a discount! Print discount card , present it to the seller - and save you money!

Monitor Buying Guide Tips


Panel technology 
CRTs have effectively been replaced by their thinner and brighter sister, the LCD. Under the umbrella of LCD technology, there are a few choices to consider before buying a monitor. First, you'll have to decide which panel technology is right for you.
The three main panel technologies currently used in LCDs are: twisted nematic (TN), vertical alignment (VA), and in-plane switching (IPS). Manufacturers make the vast majority of consumer monitors using TN panels.
Not surprising, TN panels are the cheapest of the three technologies to make. With a few exceptions, monitors that cost $300 or less will likely have TN panels. The main advantages of TN panels are their fast--usually 2ms--response time and, of course, low price. Their major disadvantages are narrow viewing angles, relatively low brightness, and inaccurate color reproduction.
Next up are VA (mostly seen as S-PVA) panels. VAs have improved viewing angles compared with TNs, better color reproduction, and they typically have a much higher maximum brightness. Also, they tend to have the lowest black levels of all three panel technologies. Unfortunately, a VA panel's response time and input lag are not quite as fast as a TN panel, and they can cost anywhere from $400 to $800, and sometimes more depending on the panel's size. Also, you can expect a VA-based monitor's profile to be wider than a TN's.
Lastly, we have IPS. IPS-based monitors are usually the most expensive; however, the new e-IPS panels cost as little as $300 for a 22-inch model. They also have the best viewing angles of all three technologies and produce the most accurate colors; however, their blacks are not as deep as VA panels'. IPS monitors are the slowest of the bunch in both response time and input lag.
Backlight
Let's clear this up right away: LED and LCD technologies are not mutually exclusive. To ask what their differences are is like asking what the difference is between Vibram Five Finger shoes and rubber soles.
So let's break down what LCDs and LED backlights are, as they relate to monitors, and delve into the real advantages of LED backlighting technology.
The term LCD stands for liquid crystal display. LCDs are an upgrade (in most respects) from tube-based CRTs (cathode ray tube) from years of old, although some still prefer CRTs over LCDs. In short, LCDs use liquid crystals to express what you see on the screen. The crystals act as a shutter for the backlight, and, depending on the type of charge given to them by the monitor's built-in electrodes, the crystals will either allow light through to the user or shut it out, thereby allowing the pixels to express their appropriate colors, making up what you see on the screen.
LED-based monitors are still LCDs (they still use liquid crystals to express images onscreen), but they use a different type of backlight than what is normally used. Most monitors of the last few years have used cold cathode florescent (CCFL) tubes as their backlight of choice.
Today, more monitor vendors are fully embracing LED backlight technology, with Viewsonic recently announcing that it's shifting its entire monitor line to use LED backlights.
To understand LED backlights, you must understand the three types currently being used in modern computer monitors.
Types of LED backlights
First up are edge-lit backlights using white LEDs (WLED) or EL-WLED. This is the type of LED backlight most commonly used in today's monitors. This entails white LEDs aligned along the edge(s) of the monitor matrix, right behind the liquid crystal array.
Using a special diffuser, the light is spread to cover the entire screen. Monitor vendors have recently refined the technology so that only one edge (not four) need be outfitted with LED lights.
The EL-WLED solution is the cheapest and smallest of the three technologies, which is why it's the most widely used. The advantages of its small design can be seen in displays like the superthin AOC e2243Fw and Samsung PX2370. You'll also see these used in many notebook and Netbook screens, and recently HDTVs have begun adopting the technology as well.
Our next technology is RGB LED. Instead of using white LEDs on one edge of the screen like the previous technology, RGB LEDs are aligned all over the panel matrix.
Each individual light is capable of producing red-, green-, or blue-colored light. This gives the display access to a high color gamut with colors more accurate than what's capable on EL-WLEDs.
Unfortunately, you won't see this technology in use everywhere, as it's very expensive and doesn't allow for a thin design. The $3,500 HP DreamColor LP2490zx uses RGB LED backlights, and its panel measures about 2.25 inches, compared with the $300 Samsung PX2370's 0.6-inch panel depth.
The final type is WLED on a flat array, covering the entire screen. Think of it like an RGB LED that's only using white LEDs instead of tricolor ones. Currently, it's only used in LED-backlit HDTVs; CNET's own David Katzmaier writes about it in depth here.
This brings us to the real question you should be asking: what advantages do LED backlights provide over CCFL backlight solutions? Well obviously this depends on the type of LED backlight; for our purposes, we'll discuss the two used in modern LED-based computer monitors: EL-WLEDs and RGB LEDs.
The following are the most frequently touted advantages of LED-based monitors. Let's get to the bottom of them.
LED backlit monitors have high color gamuts and provide more accurate colors.
Color gamut is controlled by the monitor's color filters and the backlight's radiation spectrum. While CCFL-based monitors typically offer between 72 and 102 percent of the NTSC color space , RGB LED can cover up to 114 percent. EL-WLED does not offer high color gamuts and typically hit around 68 percent of the NTSC color space.
When it comes to color accuracy, before the backlight can be a factor in the precision of a monitor's colors, the display itself must first be capable of producing a high color bit depth. While the color gamut refers to the range of colors a monitor is capable of producing, bit depth determines how many steps of those colors are within that range. The HP DreamColor LP2480zx for example has a 10-bit panel, which allows it to theoretically produce 1.07 billion different colors. Most monitors are limited to 6-bit panels, allowing only 262,000 colors, but through a few technical tricks can "fake" up to 16.2 million colors.
The use of RGB LEDs for backlighting can provide a color spectrum that closely follows the color filtering in the LCD pixel itself. This method allows the color component to be very precise with the color it's using. Also, each individual RGB LED can be tailored to produce the most vivid colors. EL-WLED backlighting is not capable of influencing color in this way.
LED backlit monitors are always superthin.
Only if they're using EL-WLED backlights, as most LED-based monitors do. It's a trade-off between cost and performance. RGB LED provides incredible color performance, but is expensive and bulky. EL-WLEDs don't really influence performance, but can produce monitors less than an inch thick.
LED backlights have lower power consumption.
Yes! At least EL-WLED backlights do. Well, for the most part. The biggest factors that affect monitor power consumption are screen size and luminance. Check out our most recent monitor power consumption chart. Most of the LED-based monitors (all using EL-WLED) are rated as "Good."
LED backlights take less of a toll on the environment when it's time to dispose of them.
True. CCFL technology makes liberal use of mercury, and thanks to the element's high toxicity level, can be a danger to the environment. LEDs contain no mercury and can be recycled much easier.
For most consumers (buying EL-WLED), LED-based monitors will offer low-power-consuming thin panels that are much easier disposed of than CCFL-based displays. Beyond that, unless you're willing to shell out $3,500, that's all you get. Not to shake a stick at power consumption or the environmental impact your purchases have, but you should know where you stand when browsing through the monitor aisle at Best Buy.
The real question is: when will vendors began offering more than just TN-based LED monitors in great numbers? Both BenQ and NEC have made some announcements in this regard this year. Keep an eye on the monitor hub for more coverage on this.

Computer Monitor Accessories Top My Holiday Gift List

Computer Monitor Accessories Top My Holiday Gift List

Although the PC has revolutionized the way we work, live, shop, and play, the promise of a "paperless office" has never materialized. Indeed, having been in the workforce for close to thirty years, it seems as though I had just as much clutter - if not more - in my office as I did before the widespread adoption of the personal computer.

The truth is that papers, sticky notes, business cards, copy clips, and office accessories were strewn around on my desk, and even a desktop organizer or card holder didn't seem to help. Each work day, I found myself searching for a phone number I need, a business card I misplaced, or - worst of all - sticky notes that somehow fell off of my computer monitor and were lost in the detritus, resulting in my forgetting to attend a meeting or missing a deadline.

What I really needed - and ultimately found - were computer accessories that actually helped me get and stay organized. I was overjoyed when I discovered a frame that fit around my PC monitor, and that held all the sticky notes, pictures, and business cards that I wanted or needed close at hand. Better than a desktop organizer, card holder, or any other number of home office accessories, this PC frame allowed me to streamline my workspace and get rid of much of the clutter.

I use the frame around my monitor to slip in a variety of important information. Along one side, I'm able to slide in those annoying sticky notes that would always fall off when I tried to stick them to the my monitor frame or that left residue when I used tape to attach them. I use the sticky notes to remind me of meetings, deadlines, and other "to do's" - and I never have to worry about them falling off. Plus, once I complete a task, it's easy to just slide one out and toss it away.

Along the top of my computer monitor, I use the frame to slip in photos of family members and friends, as well as a wallet-sized calendar. I can see the month at a glance, and every time I look up, the smiling face of my daughter looks back down at me. I love it!

I use the right side of my PC frame for a variety of items, like a list of phone numbers I frequently call, an index card that lists the steps I need to take in order to complete a repetitive task I perform at my job, and business cards from people I recently met and with whom I have to follow up. Again, it's easy to slip the papers in and out of the frame, making it a dynamic tool to help me stay organized.

Because so many of my colleagues have asked about my monitor frame, I've decided to give everyone in my office computer monitor accessories for the holidays. Several of my family members and friends have home businesses, so I'm planning to give computer gifts to them as well. Life is just so much less stressful when the clutter around your computer vanishes and you have everything you need to get the job done within plain sight.

A 17” Lcd Monitor Brings Computer Images To Life



If you have not purchased a new computer monitor recently then you might not realize how far technology has come. While everyone knows that the memory speed and capacity of personal computers has continued to grow by leaps and bounds each year, there are many people who still continue to use computers monitors that utilize outdated and archaic technology. If you want to see everything your computer can do in brilliant colors and sharp resolution, then a 17” LCD monitor is the first place you should look. 

LCD – or liquid crystal display – provides a quality display for your computer that is unrivaled. A 17” LCD monitor – a size that will fit nicely in nearly any computer hutch – has a striking resolution that can not be had in other kinds of computer monitors. With very small pixels that create the picture, the screen produces images that are clear and lacking in the grainy quality that other monitors produce. Adding to the appeal of a 17” LCD monitor is its energy use. In a world where we are increasingly cognizant of our electricity consumption it makes sense to utilize technology that uses very little electricity, such as LCD technology. 

A 17” LCD monitor does more than produce a good looking picture; it looks good while doing it as well. Gone are the days where a computer monitor was as deep as it was wide; like a small television set on your desk. The big, bulky monitors of the past are history and in their place are the slim, flat profiles that you can find in a 17” LCD monitor

The technological advances that can be found in a 17” LCD monitor do not begin and end with its brilliant picture quality and slim design. In fact, one can purchase a 17” LCD monitor that has touch screen technology that will allow you to navigate your computer using just your fingertip, or with the touch of a stylus. 

Not every 17” LCD monitor is created equally, so be sure to investigate the specifications of a monitor before you purchase. Different models vary in things like their resolution, contrast ratio, brightness, and viewing angle to specify a few. Depending on their features the prices can range greatly, from under $200 to $1000 or more. You will also find that most 17” LCD monitors are both MAC and PC compatible.
