In general, it is very hard to say which computer component is most important. Probably there is no such component. Every part is essential to perform some task otherwise we wouldn’t need it. But there is one difference. With some computer components we have direct contact. One of such components is monitor. Computer monitor communicates with us in a very special way. It displays all the information about the status of the computer as well as windows of currently active applications. Therefore, it is crucial that this computer component is carefully selected and that it displays stable and sharp picture.

Currently LCD is the predominant technology for computer monitors. There is no big difference between computer LCD monitors and LCD TV sets. The only major difference is the additional interface electronics that makes a LCD TV set look like a television and LCD monitor to look as computer monitor.

Usually, when buying computers we look at the price tag. This is normal since price ranges can vary significantly. But the price should not be the only parameter upon which we will make a decision. When buying computer monitors we should consider the following:

Main Purpose of Our Computer
We can use the computer as office tool, gaming machine, designer’s drawing board, or a combination of listed and also other purposes. Each purpose needs emphasis on a different parameter. For example, designers working in desktop publishing need large desktops and realistic color reproductions, games need monitors with fast response, etc. The first step in choosing monitor is to define the main purpose of the computer.

Size
The bigger the better. This simple rule is valid for all computer purposes. With larger working area you will easily work with many applications at the same time. Application windows will not be squeezed to small cluttered rectangles, the taskbar will look as a nice informative bar and not like a bar with many small buttons, on the desktop you will be able to put more icons for frequently used programs, etc. Because all LCD monitors are flat there will be no problem with the space on the table. So the only disadvantage with large monitors is maybe higher price.

Resolution
Again, the bigger the better. The resolution tells us how many pixels or points the monitor can display. More pixels means larger monitor or smaller image dots. A typical resolution for multipurpose computer is 1920×1200 pixels. It allows comfortable work with office programs, web browsing and also good experience with CAD programs.

Interfaces
Almost all computer LCD monitors have DVI input. This is standard for computer graphics cards. If we intend to connect multimedia devices we also need a HDMI input. Many monitors have also integrated USB hubs. This is very handy to connect keyboard, mouse and external disks. Some computer monitors have also a TV tuner which converts them into a real TV set.

Choosing computer monitor is not an easy task even if you know what to look for. For more tips and hints you can visit the LCD computer monitors website which provides few basic facts about computer LCD monitors. Perhaps the most important fact you should remember is that you will be staring for hours into this flat panel. Make sure it will look pretty.

What’s the Difference Between Ccomputer LCD monitor and LCD TV?

Television is now making huge changes. The most obvious change in recent years is the changeover from analog to digital broadcasting. This change means only modifying the way television channels are distributed over terrestrial network. The old way that worked for decades was using one analog transmitter to broadcast one TV channel using analog transmission technology. The new approach uses digital transmitters that broadcasts a package of services (including many TV channels) called multiplex. The main reason for this change is efficient use of radio spectrum. This is a limited resource and therefore needs to be used efficiently. The other reason is implementation of new services and technologies that were not possible using analog broadcasting.

The first major difference is the picture resolution. The old analog TV is considered as a standard definition television (SDTV). This means that the picture has 480 lines (USA, Japan) or 625 lines (Europe and many other countries). Unfortunately, only about 90% of those lines are visible on the screen. This small number of lines (and also low number of columns or pixels in each line) limits the resolution of the television picture. The latest trend is broadcasting high definition television (HDTV) picture which contains more lines and offers better picture with more points. HD television is only possible with digital broadcasting. This new technology together with more TV channels using the same frequency bandwidth is the biggest advantage of digital broadcasting.

HD means that the television picture contains 720 or more lines. The best HD picture contains 1080 lines and each line has 1920 points. This resolution is called Full HD. There are also other HD standards that have the number of lines between 720 and 1080. There are two variants of the HD picture: interlaced and progressive. Progressive mode means displaying HD images with all lines in each frame (static image that constitutes a moving picture). This way assures the best possible HD picture. The other option is interlaced mode which means alternatively displaying images with odd and even lines. This mode reduces needed bandwidth but also slightly reduces HD quality.

There are two competing technologies for HD screens: plasma and LCD. The old technology for analog SD television was the cathode ray tube (CRT) screen which was developed before the world war II. Both plasma and LCD work well and make high quality HD images. In general, plasma is used for medium and large screens, while LCD is used for small and medium TVs and LCD computer monitors.

LCD

The main advantage of LCD TVs is that they render colors a lot more brightly. So when you watch something on an LCD monitor, you can see the colors pop out of the picture vividly. LCD TVs also do not run on high temperatures, are lighter in weight than plasmas of the same size, and generally have longer life spans – up to 60,000 hours or more.

However, LCD TVs typically lag when they show objects in fast motion. In addition, an LCD TV’s individual pixel cell may burn out independently, which can produce annoying speckles of black and white on your screen.

Computer LCD monitors can also be used as TV. Many have a tuner built-in, and if it is not built-in you can purchase an external unit. In fact, there is not much difference between cmputer LCD monitor and LCD TV. They use the same displays. The main difference is in the interfaces and integrated tuners and decoders.

Plasma

Plasma is a technology used to create HD screens. When you watch something on a plasma screen, you will find it hard not to be surprised. The image registered on a plasma TV screen is much more gorgeous than one you will see on an LCD monitor. That is because plasmas are better at color saturation and accuracy, and they show black more deeply. They are also great with tracking fast movements on screen.

The trouble with plasmas, on the other hand, is that they can get really hot to the touch. The individual phosphors in the plasma’s pixel cells can also burn in easily on static pictures. The life span of a plasma TV set is also smaller in number than that of the LCD.
