Best Portable LCD Monitor
LCD – Liquid crystal display device
LCD screens are the most popular for professional screens. The LCD (Liquid Chrystal Display) image is generated by the backlighting of liquid crystals, which are illuminated by fluorescent tubes. Now, the majority of professional screens are equipped with LED (light-emitting diode) lighting, so that the liquid crystals are lit not by fluorescent tubes but by light-emitting diodes. In principle, there are two types of LED backlighting: Edge LED and Full LED.
As for the Edge LED, the light emitting diodes are only distributed around the periphery of the screen and are facing inward, so that the entire surface of the screen is illuminated via a photoconductive glass plate. With the Edge LED, a perfectly uniform light distribution is not possible, however the Edge LED flat screens are very advantageous in terms of price.
For Full LED backlighting, many small light emitting diodes illuminate the entire screen covering the entire surface of the screen. With the Local Dimming function, some parts of the picture can be darkened and others brightened, so that the contrast is better and more dynamic.
How to choose your PC Monitor?
To choose the best PC monitor for your personal needs, you should also know the definitions of the features that you will find mentioned among the prices of the different models. In addition, you need to know the size of the space you want to occupy on your desk and the diagonal of the image display surface.
Technologies: IPS, VA or TN?
Let’s immediately start to distinguish between the different types of screens currently available in stores and see what are the technical characteristics to consider before buying one. The first choice you have to make is on the type of panel: all screens currently on the market are LCD (liquid crystal, with LED or fluorescent backlight) but be careful, all LCD screens are not the same. Depending on the type of panel used, they can be distinguished into TN, IPS and VA.
The TN monitors (Twisted Nematic) are known for their low response time (up to 1 ms) and are often available at a good price. They are best suited for video games and viewing 3D content.
The IPS panels (In Plane Switching) on the other hand, are more oriented towards the world of productivity and multimedia, as they adjust the colors better than TN and angles much observation, but the response time almost always Student.
VA monitors offer a good viewing angle and contrast, but don’t have very low response times, and color reproduction is not as perfect as on IPS panels. They can also suffer from the annoying ghost effect. They are divided into PVA (Patterned Vertical Alignment) and MVA (Multi-domain Vertical Alignment) having even more marked contrasts than the first ones. This type of sign must be taken into account especially in the workplace.
Each monitor may support higher or lower resolutions, or technologies that may or may not be useful in certain areas. Below, we provide some definitions of the essential characteristics of monitors.
You should not only look at the size, which is the number of inches, but also the resolution, which is the maximum number of pixels that can make up the images on the screen. Display sizes typically range from 18.5 “to over 30”, while when it comes to resolutions, we have several options available.
HD monitors: The cheapest monitors available on the market today are those with HD resolution, equal to 1280 × 720 pixels in 16: 9 aspect ratio. To date, they are a bit anachronistic and we do not recommend them, unless you are very demanding and want to spend the bare minimum.
Full HD monitors: They have a resolution of 1920 x 1080 pixels and are currently the best solution in terms of value for money. They are also ideal for games. The recommended dimensions for this type of screen range from 21 ″ to 27 ″, also because if you play too close on a large screen, you risk eye strain.
2K monitors: They have a resolution of 2560 x 1440 pixels and are particularly suitable for working with photos and videos. The recommended dimensions for this type of display range from 27 inches and larger.
4K or Ultra HD monitors: Featuring a resolution of 3840 × 2160 pixels and are the best on the market today. They can be used in various fields, mainly photo and video processing, but are also good for games. They must be associated with a computer and, above all, with a high performance video card, otherwise they end up being counterproductive.
Other characteristics of the screen image
Response times: one of the main features to look at before purchasing a monitor is also response times, which is the number of milliseconds a pixel takes to change its state on the screen (this setting is fundamental for gaming, and it should be as low as possible if you need a monitor to play)
Frame rate: This metric is used to indicate the number of frames “rendered” per second by the computer graphics card (FPS) and establishes the smoothness of the animations and any movement. It is mainly used in video games or multimedia content.
Refresh rate: represents the refresh rate of the screen image, that is, the number of times the image is redrawn on the display every second (measured in Hz). The last two settings are better when they are higher. In addition, NVidia G-Sync and AMD FreeSync technologies have recently appeared among the most demanding gamers. They allow you to synchronize the frame rate to the screen refresh rate, in order to avoid the reproduction of annoying artifacts
HDR (High Dynamic Range): Indicates the ability of the monitor to reproduce a wider range of colors, including shadows and reflections that SDR (Standard Dynamic Range) monitors cannot display. It is an exceptional innovation, because this model offers very high quality static images. For example, an HDR monitor can reproduce very bright lights and dark shadows in the same frame, without burning the first or obscuring the details of the second.
Glossy or Matte Display: Screens can have a glossy or matte finish. Those with a matte surface avoid reflections, those with a glossy finish rather have more problems with reflections but ensure more vivid colors (so, in theory, they also tire the eyes more easily).
Each PC monitor is connected to the computer’s graphics card via a cable. However, there are different types of connectors offering different transfer speeds. Obviously, not all connections are present on all screens and all graphics cards. Here are the main connectors:
VGA: An obsolete connector for modern video cards, compatible exclusively with samples from years past.
DVI: the successor to D-SUB, is included in almost all modern monitors. Qualitatively and quickly transmits a signal, thus offering an increase in maximum resolution.
HDMI: has more bandwidth than DVI. Supports all resolutions up to 4K. It can transmit both audio and video signals, thanks to which it can be used to connect not only to the mainframe, but also to other multimedia equipment.
DisplayPort: One of the most used connectors on current graphics cards. It allows without problem to display an image in 4K resolution, even beyond.
How to use a PC screen?
Both at work and at home, we can hardly do without screens, and even less those of our computers. Very important for the good use of your PC, this is a device which has quickly modernized on the market. But be aware that its use in itself will require some precautions. These will be explained to you throughout these next paragraphs.
Make sure you choose the right size
When looking for your PC screen model, you will surely come across various device sizes varying from 19, 20 and 22 inches. However, the choice of the size of your screen will have to be made according to your use. For advanced image editing or for intense gaming sessions, screens from 24 to 26 inches will be recommended. Otherwise, the reduced dimensions may already be sufficient.
Choose a reliable installation
If the location is not chosen correctly, your screen may slip and be completely damaged. This is why it is recommended that you choose a relatively stable location for it, away from damp corners and too hot spots. Also, make sure it is completely placed in the middle of your desk to avoid any risk of falling.
Pay attention to your arrangement in relation to your screen
To avoid eye pain, it is essential that you maintain certain distances from your computer screen. Especially if you are already a regular and it is easy to write without looking at the screen, make sure that the top side of the screen is just at eye level. Otherwise, impose a distance of 10 to 15 cm downwards. On the other hand, medical professionals recommend a distance of 50 to 60 cm between your eyes and your computer screen.
Familiarize yourself with the brightness adjustment options
To make your PC screen a comfortable device to use on a regular basis, you will need to adjust its brightness. To do this, you just need to identify the adjustment buttons usually included on the front or the edge of the screen. Subsequently, use the Menu button or directly the arrows or + signs to modify the intensity of brightness and contrast to your liking.
Remember to maintain the device regularly
Like any device of this kind, maintenance is an important action that can greatly affect its durability. For the PC screen in particular, we recommend using a microfiber cloth to quickly get rid of dust. Fingerprints can be easily wiped off with a soft, slightly damp cloth. As for more stubborn stains, you can use a cotton ball soaked in a mixture of white vinegar and water. When cleaning, adopt the same movements, always from top to bottom, and from right to left. Remember to finish with a dry cloth.
