How to choose high-quality LED display?

The main element of the personal computer is the monitor. Therefore, choosing a new technique, it is important to pay attention not only to design but also on its technical parameters. From the right of the selected display it is not only the work of a computer, but the convenience and health of a person.

How does the LED monitor

The monitors with LED-backlight instead of fluorescent lamps, high-quality LEDs are used. Thanks to this technology to view video in FULL HD format is a pleasure. The image is bright and realistic.

In addition, LED-displays are durable, economical, they do not contain harmful to the environment and human substance.

The quality of the image depends on the following factors:

• contrast;
• brightness;
• angle;
• color range;
• Update frequency;
• blackness.

Due to this illumination producers have managed to increase the image quality, brightness and contrast. LEDs do not contain mercury, and 2 times consume less electric power.

Another advantage - LED-displays are thin and compact, does not occupy much space on your desktop. Dynamic backlight has a saturated color reproduction.

LED technology is constantly improving, so they are much cheaper and consume less energy than it did previously. They are resistant to rebooting, shocks and low temperatures are not exposed to high voltages and do not overheat.

The main advantage - the productivity and efficiency.

Features LED Monitor

When choosing LED-monitor is important to pay attention to the brightness and the backlight. The rates are higher, the less they react to external light sources.

When choosing new equipment for a personal computer it is important to pay attention to the technical characteristics of the device:

• screen diagonal;
• display resolution;
• coating;
• angle;
• response time;
• matrix;
• brightness;
• lighting;
• contrast;
• ergonomics;
• power consumption.

Select a screen diagonal depends on the purposes for which it will be used. For those who are professionally working with graphics fit the monitor with a diagonal of 25 inches and above.

fit displays with a diagonal of 19 inches for the office. For use in the home 19 - 25 inches. The image quality is dependent on the screen resolution. On the large screens at the same time convenient to work with multiple files.

Another important parameter is the response time of the display, at a time when changing brightness of the screen. The smaller the number, the faster the image changes. These parameters are particularly important for those who like to play games with 3D graphics for viewing high-resolution movies (FullHD). Optimum performance is considered to be the response time to 5 ms.

Coating

Covering LED-display comes in two types: high-gloss and matte.

Frosted less reflects light and glare from surrounding objects, compared to glossy. Glossy advantage that they have high brightness and colors. Optimum viewing angle - 176 ° vertically and horizontally, which allows the image viewed from all sides.

Functions LED Monitor

Modern LED-monitors are responsible not only for displaying information on the screen, but also equipped with additional features. With an HDMI port to connect to not only your computer but also other multimedia devices. In place of an analog connector VGA, in modern devices use a new - digital DVI.

In addition, most modern monitors have additional functions:

• 3D - support;
• USB;
• stand;
• TV-tuner;
• acoustics;
• MHL.

Some models have built-in speakers. This saves space on the desktop. The sound quality is not as high, but it is enough to communicate on the network.

Monitor Stand allows you to adjust its position, change the height or to turn it to the left / right. With it, you can adjust a comfortable position LED-display.

TV-tuner - can receive digital or analog TV signals, is equipped with a remote control.

MHL port for connecting mobile phones / tablets to monitor. This allows you to charge your smartphone or tablet, as well as broadcast video over the Internet in Full HD.

How to use

Although LED-displays are durable, it is still necessary to follow the rules of operation of the equipment. Please note that the correct installation of office depends on the state of the eyes, neck and spine.

monitor height should be slightly above eye level. If you look in the middle of the screen, the eyes should be directed downwards. This reduces eye fatigue. The display must be positioned on the eye in the region of 40 to 70 cm. To my eyes are not tired, every 10-15 minutes, focus the eye on the nearest objects. To warm up the eyes blink more often.

How to install the LED-display:

1. To reduce glare and reflection of other nearby objects, it is necessary to place the device at an angle of 90 °. This applies to devices with a glossy finish. The light from the desktop and ceiling lights do not reflect on the screen.
2. For convenience and comfortable viewing of the video you want to adjust the contrast and rage.
3. In the office and at home, when working with documents, it is better to use special holders to reduce head movements when working with documents.
4. Gadgets and other fixed elements, it is desirable to turn off while typing.

It is not recommended to connect in a place where direct sunlight, as well as near the battery. High temperatures adversely affect the performance monitors. They can fail before the warranty period.

The monitor should not lay anything, such as magazines, books, newspapers. They cover the ventilation holes, thereby impair the operation of the cooling system. Provide unobstructed air penetration.

Pets do not allow to be near a monitor, as animal hair enters the vent and prevents the normal circulation of air.

Shelves with flowers set away from the equipment to prevent water from getting inside it. Take care that small children do not touch the display with pencils, pens and other sharp objects.

Regularly remove dust from the surface of the special napkins equipment, at least 1 time per week. If not, you can wipe the screen surface with a soft cloth made of microfiber. Do not rub the screen hard tissue, they leave scratches on its surface.

To clean the case, disconnect the equipment from the power supply.

Precautionary measures

1. Do not open the protective cover of the product when connected to the mains. A high risk of electric shock.
2. It is not recommended to pull the cord to disconnect the device from the mains.
3. You can not use the sink in the kitchen or in the bathroom, with an unstable stand.
4. Do not install on an unstable surface. For drop can damage the matrix.
