Computer screens as an alternative to TVs and laptops
The current period is witnessing a wave of desktop computers, due to the demand of users to buy modern “laptops” to accomplish their work, due to the light weight and high performance of these devices, in addition to many other advanced functions. Despite this, traditional computer screens still maintain their position in the market, as users rely on them as a large screen for laptops, and they can also be used as a substitute for a television set. The German Association for Communications and Information Technology in the capital, Berlin, indicated that there are many users who do not install TFT screens in desktop computers, but they use them as an external display unit for laptops.

| HDMI socket The HDMI socket is not only limited to TVs, but it is becoming more common in monitors such as other DVI connection ports as well as DisplayP. However, companies fail to include an HDMI cable in the monitor kit, and the user usually has to purchase this cable separately. Some models have two sockets, while others offer several connection ports, which allow the monitor to be connected to any computer. Some models are characterized by an increasingly blurring of the boundaries between the screen and the TV, and some TFT screens, for example, come with a TV tuner to receive digital TV channels, or their equipment package includes a media player. These monitors are able to play videos from external hard disks, without the need to turn on a computer, but the disadvantage of such add-ons is the increased consumption of electrical power. |
This is due to several reasons, including health factors, because the large screen maintains the health of the eyes and back, through a standing sitting position in the case of fixed work at the desk, and this applies to users who sit for several hours at once, or every day in front of a computer screen.
“Large screens are not only useful for owners of (laptops), but can also be used by users of computers with small screens or old screens using cathode ray tube (CRT) technology,” says Roland Stele of the German Association for Entertainment and Communication Electronics. All new models are currently working in Ultra High Definition (HD) technology, and Full HD technology has now become a standard equipment in almost all screens. This screen is on the market.
UseGerman experts advise that before buying the monitor, the user should think carefully about the exact purposes of use, because the critical values and functions in the purchase process differ depending on the purpose of use. The German expert, Stiele, explained that “the user who needs a screen to display files and data only, can overlook the response time to some extent,” because spreadsheets and word processing do not rely much on the issue of changing the image quickly, but for computer game lovers and ultra-high-definition movie enthusiasts They have to take into account the issue of the speed of changing the image, and therefore the focus should be on the response time to be as fast as possible. Experts advise that the response time is three to four milliseconds at most. It is also important in such cases that the screen be as large as possible, and such screens are currently working with a newer technology than Full HD, and no distorted “pixels” appear on these large screens in the wide screen setting mode. There are some 27-inch screens, for example, that display images with accuracy and clarity, but the high density of the number of “pixels” requires a graphics card with a high capacity, in addition to that it is not possible to display some computer games with such high-resolution clarity. Experts explained that the screen is excessively large, if the user cannot see the entire image without moving his head, and therefore the space available on the desktop and the distance between the user and the screen are vital when buying a new screen. It is also important for the screen to have the ability to rotate and adjust in terms of height, as the German “Ship Test and Cave” magazine indicates that a user who is unable to perfectly align the screen position in proportion to his sitting position as a viewer, may experience neck pain in later.
