There are several advantages of LCD Monitors over the old CRT Displays. While LCD Monitors are compact and lightweight and consume less power approximately 20W whereas the CRT monitors are bulky and heavy consuming upto 150W. An LCD Monitor produces perfectly sharp images with perfect image geometry whereas in CRT the sharpness is limited and it tends to blur more at high brightness and with the aging of the tubes and suffers from geometric distortions.

LCD monitors have a consistent tonal scale and can display text with excellent contrast whereas the CRT monitors display strong bright areas which can cause other regions of the picture to dim and also has poor text contrast because of limited bandwidth.

LCD monitors do not normally flicker whereas a faint flicker can always be observed in a CRT monitor.

There are also some inherent disadvantages of LCD monitors over that of the CRT monitors. The contrast or the color changes with the viewing angle in a LCD monitor whereas in a CRT monitor it is always a consistent image irrespective of viewing angle. LCD monitors may cause motion blur and has a poor black on dark images. Whereas the CRT monitors usually portray motion well and also has good black contrast.

When viewing photos or videos on a LCD monitor it may appear flat and the peak brightness is limited by the back light. A CRT monitor displays movies/video/photos with a sparkle and life to images with very high peak brightness.

If LCD Monitor screens are damaged, it may develop stuck pixels whereas no such pixel based problems are present.

In LCD the natural interface would be digital e.g. DVI interface and the image can be sub-optimal with analog interface whereas CRT’s are naturally suited to analog interface.

On the basis of image-quality LCD monitor is best suited for technical/CAD applications and office uses such as large, detailed text-based but -non-critical color graphics while CRT still has the upper hand for high-end photography or art work and for television displays.

Unlike CRTs that are actively displaying the light through coated phosphors, an LCD actually takes white light and filters it to get the desired colors. To do this for each given pixel there are three sub pixels one for red, green and blue light. When the sub-pixel is off, the filter will block that particular color of light. When the sub-pixel is on, it will open the filter to let a desired amount of light through.

The Minor Issues

Dot Pitch/Pixel Size

Dot pitch is the distance between phosphor dots (sub-pixels) or between TFT LCD cells of the same color on a display screen. A smaller number generally means that the image on the screen is sharper, as there are more dots in any given area.

A display with a smaller dot pitch is usually better, but this is not always true because of the methods used to measure it. There are many methods of measurement as well as differing pixel geometries on the screen and differing screen resolutions when judging image quality on the display.

Most of the time, dot pitch is measured on the diagonal, this gives the most accurate representation of dot pitch of the display. Later some companies introduced a horizontal dot pitch measurement. By measuring only the horizontal dot pitch and not the vertical, cheap, low-quality displays can appear to have a smaller dot pitch.

For example, a display with a 0.28mm (diagonal) dot pitch has a horizontal pitch of 0.24 or 0.25mm depending on some monitor construction variables, a good quality 0.26mm (diagonal) display has a horizontal pitch of 0.22mm.

Be careful not to get the two different measurements confused as that 0.26mm dot pitch monitor may have more dots per millimeter than the 0.24mm dot pitch display.

Contrast and Brightness

Contrast is the ability for the monitor to vary brightness between the foreground and the backgound. It is expressed in a ratio ( i.e. 500:1). Typically the higher the ratio, the better the image quality will be as the display will be able to show bright colors next to dark without washing out the black or dulling the colors. Display brightness is expressed in candela (cd) and is defined formally as:

Phew, what this means to us it that the greater this number, the brighter the display is capable of being. However, you must watch the power consumption of the unit. A display that has a very high brightness level will consume more power than others with a lower value. The old adage, “a light that burns twice as bright lasts half as long” sort of applies here. So a trade off between brightness and power consumption is something to watch.

Viewing Angle

CRT monitors are viewable from almost any angle. That is to say if your view is not blocked by the curve of the screen or the surrounding plastic frame. TFT LCD’s have a narrow focus and therefore can only be viewed from inside a certain arc of angles. As the technology improves, this arc is being improved. This should not have any affect on the primary user of the PC, as they should sit facing the display. But if you like to have bystanders watching you achieve the ultimate score on puzzle bobble or you are trying to show off to your girlfriend your best trick in Tony Hawk’s pro skater, then you may have some issues (and they also might not be able to see the monitor

Analog vs. Digital connectors

More and more graphics cards are coming equipped with DVI connectors. But should you get a display with a DVI connector, and analog connector, or one of each?

The advantage of a DVI connection over the analog is that the DVI connection allows for lossless transmission from the computer to the display. Signal noise, for instance, should not be a concern with the DVI connection (no more hum bars on the monitor when the vacuum is being used). It also provides support for much higher data rates which are needed for the larger diplays (such as cinema screen size displays). Currently, no other advantages of the DVI connection specification are being exploited. If you would like to know more on this subject go to the Digital Display Working Group (DDWG) who developed the specification.

What To Look For When Buying

As mentioned earlier, Response Times are the primary concern of any TFT LCD screen. Viewsonic is advertising their VP201s monitors as having Response Times (Pixel Response, Video Response) that are fast enough to present “Realistic, artifact-free 3-D gaming.” These monitors have a “blistering 16 millisecond (16ms) Response time.” Hitachi also advertises their CML174B and CML 175B LCD monitors with Response Times of 16ms “enabling smoother computer video, animation and gaming movement.” Samsung goes one step better with their 172X LCD monitor that sports an amazing 12ms Response Time.

Next, be sure to select a screen that has a native resolution that meets your needs. That is to say, if your system can only play games at 800×600 then buying a 2048×1536 monster display won’t give you any advantage and will almost certainly do more to hinder your game playing and your enjoyment of it.

Check the dot pitch measurement and make sure you are comparing like-for-like if you are looking at more than one display, especially from different manufacturers.

High contrast and high brightness, but low power comsuption is a very good combination because this will give you impressive visuals and your display will hopefully last longer.

Other, smaller, concerns (like the price) I will leave to personal preference. A TFT LCD that satisfies all of these criteria will hopefully do justice to your game visuals and give you the gaming experience that you desire.

The first step in installing rack mount LCD monitors is to get out and get one. They are available at most any home office or electronics store. Since the rack mounts are becoming more popular, they are easier to find now then aver before. Once you have your set, bring it home and spread all of the parts out along with the instructions so you can find what you need.

The first step will be to install the slides on your desk. Some rack mounting sets will include slides that are “handed.” That means that each slide is assigned a side of the monitor rack, but there are also sets where either slide can go on either side. Consult the instructions with your set to make sure you have mounted them correctly.

Next of the steps in installing rack mount LCD monitors is to hook up the cable bracket if your set has one. The cable bracket will keep the computer cables from being tangled up in the apparatus of your rack mount. Generally these will go to the rear of the entire mount system.

Third, you will likely be required to install the fixed mounts. These are what will keep the apparatus stable and secure with your computer monitor in it. Follow directions carefully so that you can be sure to get everything installed tightly. This is what will keep your monitor safe, so double check all screws and studs. They will connect to the system which will then connect to the slides you installed to begin with.

Once that is all installed, it is time to get your LCD monitor put into the rack mount. This will allow you to slide your monitor and keyboard in and out from the desk. Overall it will save you a great deal of space. Make sure you carefully follow the directions and precautions contained in them. That will keep your equipment safe and your system stable. Once installed, you will be able to start using everything immediately.

Knowing the basic steps in installing rack mount LCD monitors will give you a head start when you go to install yours. You will be able to easily slide your monitor and keyboard in and out saving space and making you more comfortable. Once you get used to it, you will be in love with your rack mounted LCD monitor. Just make sure you follow directions carefully and double check every step of your installation. Before you know it, you will have a rack mounted LCD monitor ready to go.

The first of the tips in buying car LCD monitors is to decide what type of monitor you need. There are a number of types of monitors that show in cars now. Do you need an overhead video monitor so the kids can watch DVD’s? You may need, instead, a flip down video monitor that can be used to show videos and then fold into the ceiling.

Additionally, there are in-dash monitors, headrest monitors, and even sun visor monitors. So you need to make sure, before you buy anything, that you know which kind you are buying. Where the monitor is will affect the size you buy and the quality you get as well.

Next, you need to make sure that your vehicle will support the monitor you want to install. Check with the manufacturer to make sure your electric system and interior is capable of supporting the monitors you want to install. If you cannot install it, then you can save yourself the trouble of buying in the first place.

Once you know what kind of LCD monitor you need for your car and that it can be installed in your vehicle, it is time to shop. Your shopping should begin by getting an idea of the baseline costs of what you need. By starting with the internet, you can compare a number of prices in a hurry and get a feel for what the market is like. Once you know what the internet is offering, then start looking at brick and mortar establishments.

Talk to sales people and find out what costs are like. Compare the prices to the internet prices you got before and make sure you are getting the best possible deal. Additionally, you may want to inquire about installation as well. It can really save you the pain of trying to install a dash monitor or something in the head rest when you are not familiar with it. This is also the time to look into financing if that is something you are interested in. Get all questions out of the way early so that you know exactly what is going on.

Use these tips in buying car LCD monitors to enhance your vehicle. You can also make repair replacements if need be. The point is that you should be diligent and take the time to do a little homework. By familiarizing yourself with the prices, the compatibility with your car, and your installation costs, you will be able to make an informed and smart decision about the LCD monitor you buy for your car.

Colour:

The quality and clarity of colour is still better on CRT monitors when compared to a standard LCD monitor. But the new generation of LCD monitors incorporate technology which can compete with the best of CRT monitors. The new monitors are VGA TFT LCD and this makes all the difference. Placing them side-by-side, it would be difficult to spot the quality difference.

Brightness:

As LCD monitors contain more components than CRT monitors, it gives it an advantage when it comes to comparing brightness. LCD monitors are almost twice as bright as CRT monitors.

Size and Weight:

The comparison here is obvious. Almost all that LCD monitors are flat panel. This means they are easy to manoeuvre and placed in tight spaces. LCD monitors can be as thin as 1 inch. LCD monitors can appear on the smallest of devices such as pocket PDAs. Not only are CRT monitors fat and ugly, they can weigh almost 10 to 20 kilos more than LCD monitors.

Contrast:

The old LCD monitors weren’t very good in dimmed situations. The contrast settings on a CRT monitor portray light situations as they should. However, the new era of LCD monitors are much better at colouring tones than before. If you place new LCD monitors and standard CRT monitors side-by-side, the difference is negligible.

There are many more items you can use for comparison purposes such as power consumption, screen burn, dead pixels, screen flickering, response time, rack mounting, magnetic interference and video sources. To read more, visit www.monitor-land.com

In conclusion, CRT monitors were better than the standard LCD screens but with today’s technology, LCD manufacturers such as Sony and Dell, have moved forward and made the better screen type even better. I vote for LCD monitors.

I did some research before I bought this monitor which I would be delighted to share.

So why did I want a LCD in the first place? The advantages are many – easier to move around/clean as they are thinner, lighter and take up much less space, less eye fatigue, more energy efficient than a CRT (less power consumption) and of course LCD screens look good.

The first thing I thought about was the price obviously. I didn’t want a very expensive model but I wasn’t going to buy a ”no-name” brand either. Then came the size – I was using a 17” Samsung monitor so I7” was good for me. During my browsing, I saw how beautiful things look on a 19” screen and after comparing the price with India, I went in for a bigger screen. The next thing on my list was the response time. I wanted a fast response time (8-12 ms) so that when I played games, the image didn’t ”ghost” (motion blur). My Benq screen has a response time of 8 ms and I have not seen any blurring at all. I was also careful of the ”dead pixel” policy of the maker. You see, LCD screens are notorious for dead pixels – even one dead pixel in the middle of your screen can ruin your LCD experience. Before you buy your LCD, get the salesperson to display a full white image on screen first followed by a full black image (easily done in Microsoft Paint) so you can weed out dead pixels. Check the dead pixel policy of the company. If you do find dead pixels in the warranty period, will they replace your monitor? Do try to test your LCD monitor before buying it – make sure that the salesperson gives you the same monitor and not a new untested one.

A couple of things to remember about a LCD screen – it has a field of vision restriction which means that you have to sit directly in front of them to get a good view. The better the product, the larger will be the field of vision and there will not be a darkening of the screen from a ”not in front” position. All LCD monitors have, what is known as, a ”native resolution” which essentially means that they give their best performance at that resolution. For example, my 19” monitor has a native resolution of 1280 x 1024 (SXGA). Any other resolution looks washed out and blurry. Choose your resolution depending on the size of the screen you buy. For me the best resolutions are as follows: 15” – 800 x 600 or 1024 x 768; 17” – 1024 x 768; 19” – 1280 x 1024. Physically try out various resolutions before you buy the screen – maybe the salesperson won’t have a clue about the native resolution.

Game enthusiasts and DTP people will still prefer the CRT screen as they can buy bigger screens for the money they spend on LCD screens. In addition, the colours are brighter and there is no motion blur on CRT screens (provided you have a good video card). If you have space limitations or work extensively with ”words” – word processing, Internet browsing etc, go in for a LCD monitor, provided of course you can afford it. Some LCD monitors come with speakers which makes them perfect for offices. But serious music lovers and game enthusiasts will hate the tinny sound.

I am very happy with my Benq FP91G screen and would recommend it without hesitation. Other companies like Acer/Samsung/Viewsonic make LCD screens which are equally good but prices differ. So sniff around a little before you splurge.

The salient features of the LCD technology include brighter, clearer, and sharper images obtained at a click of a mouse. Features such as a high picture resolution, color, clarity and brightness coupled with improved visibility of smaller fonts and a reduction in response time have all contributed towards increasing the market demand for LCD monitors by industrial enterprises ranging from banking, ATMs, games to hospitals and restaurants.

The dynamics of constant research has resulted in many advances in this technology. Initially incepted for a screen of about 12 to 14 inches, LCD is now a popular choice for a 50-inch screen. Another benefit of the advancement of technology is that the manufacturers have been able to cut down on the cost of production. This in turn, has brought down the cost of LCDs thereby making it a feasible choice for various industrial enterprises. Also, the LCD has a long life of about two decades allowing a person to use it between 8 to 10 hours daily.

The advantages of LCD monitors are such that they are gradually replacing CRT or the cathode ray tube monitors. This is because LCD technology is better for the eyes. LCDs have uniform screen brightness. Also, the screens covered with a flexible surface are less susceptible to glare as compared to the CRT screen.

Given the advantages of LCD, it is not surprising that LCD monitors are slowly and steadily replacing the conventional computer systems that used CRT technology for the computer display.

A great place to start your search for a LCD monitor with TV tuner is through Consumer Reports. They will give you unbiased reviews of the LCD monitors with TV tuners out there. You can find Consumer Reports online at http://www.consumerreports.org.

If you are the type of person who needs to see in person what it is they will be buying, then it is a good idea to visit a major big box retailer in order to get an idea of what kind of LCD monitor with TV tuner you are interested in. Make sure you take a pad and pencil with you so you can write down the model numbers of the LCD monitors with TV tuners that you liked the best. This will give you a good place to start comparison shopping.

Here are a couple tips if you decide to buy a LCD monitor with TV tuner for yourself online as opposed to a bricks and mortar store. First of all, you need to take into consideration the cost of shipping and what that will add to the overall price. Let’s say you find the LCD monitor with TV tuner model you’ve been searching for online, it is in your price range and it appears to be a couple hundred dollars less than it would be if you bought it at a major retailer. Shipping could easily add an extra couple hundred dollars to the total price, so you wouldn’t be getting much of a deal after all.

Another thing to consider when shopping for a LCD monitor with TV tuner online is that you should shop through a reputable dealer. Before whipping out your credit card you want to make sure that they are a reputable business and offer a warranty as well as everything else you would get from shopping at a reputable bricks and mortar store such as one that might be located near your house.

That being said, LCD monitors with TV tuners currently available on the market change often so it’s hard to write a review that will stay valid for a long time. Things change often, so it might be best to just stop by our site and see what we have to offer you today.

No display or white screen:

If this is a new install make sure the refresh rate is not set too high. If you installed a new video card in your system make sure the refresh rate is not set too high. Under Windows, reboot the system and go into “Safe Mode” (Use F8 key on boot up) select safe mode and change the refresh rate under display properties to either 60Hz or Default. Then reboot the system and the screen will turn on. Maximum mode on 15″ TFT screens is 1024×768 and maximum mode on 17″ and 19″ TFT is 1280×1024. Check to see if the green light is on with the external power adapter. Make sure all plugs are secure and the video cable is properly attached to the computer.

Dark screen in games:

TFT Liquid Crystal Display monitors are a unique devices that are manufactured to meet excellent picture clarity and reproduction in a native mode. Outside a native mode graphics will be darker, fine lines and text will be thicker. Native mode for 15″ TFT panels is 1024×768, 17″ and 19″ TFT panels are 1280×1024. Most games can be configured to run at 1024×768 which should produce clean graphics.

Thick text:

As described above, TFT LCD monitors perform best in their native modes. Other modes can be used however the reproduction of text will vary in thickness depending on the mode the monitor is running in. Best text reproduction is view in the monitors native mode.

Faint or unseen text:

TFT monitors are Bright! So bright that sometimes text in a DOS program may be very faint or not seen. In order to see this text, you can reduce the contrast level down until the text is visible. TFT LCD monitors were manufactured to perform in a GUI environment such as Windows, Linux (X) and Macintosh. Older designed programs may have upgrades to enhance this effect to make the text legible.

Wavy lines on the screen:

In some instances you may encounter wavy lines on the screen. These are usually 1/4″ thick and move in a vertical motion. This is caused by a noisy electrical feed from a wall outlet. If you change your vertical refresh rate under display properties to 75Hz this effect should disappear.

Small dot on screen:

TFT panels by their very nature are difficult to manufacture. KDS uses displays from various suppliers including; Samsung, Hyundai and Acer, who all guarantee the display to be 99.99% free from pixel defect. What that means is a 15″ LCD display can have up to about 6-10 broken pixels and still be considered “acceptable”. Broken pixels are individual pixels, which are stuck on, off, or as one particular color. Depending on their location and intensity, they can be next to invisible or obvious. This is common to ALL TFT screens and is not considered a defect by the screen manufacturer.

Dark areas:

Retail TFT LCD monitor products employ the use of a single TFT backlight. This backlight is responsible to deliver full edge to edge brightness across the screen. On some models the screen may not be as bright in the center or the edges as other areas. This is due to the design the actual panel manufacture took to keep costs down so that the TFT panel is affordable for the retail environment. Prices of TFT panels vary according to added features (TV tuner, SVIDEO etc.). They also vary according to the number of backlights that are in the panel. High-bright monitors with multiple backlights can cost upwards of $2,500.00 for a 15″ panel.
