Compare by input type


As monitor technology has evolved over the years, so have the types of inputs you’ll potentially use to connect your monitor to your PC and other devices. The most common way to connect your PC to your preferred display is by HDMI, but most modern monitors feature either HDMI or USB Type-C input options to be easily compatible with today’s tech.


If you’re a gamer, you’ll most likely be in the market for a DisplayPort monitor as DP cables are generally preferred by gamers due to their greater bandwidth and ability to take advantage of top graphics card software.


Many monitor manufacturers, including Lenovo, also still offer VGA displays. VGA is a more dated method of connecting your PC and visuals but there are still plenty of PCs around that may require this input method.


Be sure to research and consider the type of input option that will best connect with your PC and support your usage habits before you buy.

Monitor is a device for operational visual communication between the user and the control device and displays data transmitted from the keyboard, mouse or central processor. The fundamental difference from a TV is the absence of a built-in tuner designed to receive high-frequency signals from on-air (terrestrial) broadcasting and an image signal decoder. In addition, most monitors do not have a sound reproducing path and loudspeakers.

Modern monitor consists of a screen (display), power supply, control boards and housing. Information for display on the monitor comes from an electronic device that generates a video signal (in a computer – a video card or graphics processor core). Televisions can also be used as monitors, most of whose models have been equipped with low-frequency inputs since the 1980s: first RGB signals, later VGA, and the last generation HDMI. All early home and some professional computers were designed specifically to use the TV as a monitor. The decomposition standards of the first video adapters (MDA, CGA) also coincided with television ones.

Monitors designed to monitor and (or) control a television image are called video monitors. Such devices, used at different stages of television production, differ from the TV in the absence of a tuner. In addition, professional video monitors display the television raster completely in Underscan mode for full cropping control. The color accuracy of video monitors is subject to increased requirements for use as a reference. Professional video monitors are often made in a housing adapted for installation in a standard rack, most often 19-inch.

A monitor designed to output information from a computer, performs the function of a display and differs from a video monitor in a decomposition standard that does not coincide with television. As a rule, computer displays, including those with a kinescope, have a higher line and frame rate and clarity than video monitors for standard television. This is dictated by the conditions of long-term observation of the image at close range. In addition, computer monitor video inputs are made on a component rather than a composite basis.

Personal computers usually work with one monitor (servers do not require a monitor at all), but there are video adapters that allow you to connect more than one monitor to one PC, and you can usually install more than one video adapter in a PC. Most modern laptops, in addition to their own LCD display, have a connector for connecting an external monitor or projector, which allows you to expand your workspace or duplicate the image from the LCD display.

What is an LCD monitor (LCD, TFT)?

Liquid crystal monitor (also liquid crystal display, LCD, LCD monitor, English liquid crystal display, LCD, flat indicator) – a flat-panel monitor based on liquid crystals.

LCD TFT (eng. TFT – thin film transistor – thin film transistor) – one of the names of the liquid crystal display, which uses an active matrix driven by thin film transistors. The TFT amplifier for each sub-pixel is used to improve the speed, contrast and clarity of the display image.

How does an LCD monitor work?

Each pixel of an LCD display consists of a layer of molecules between two transparent electrodes, and two polarizing filters whose planes of polarization are (usually) perpendicular. In the absence of liquid crystals, the light transmitted by the first filter is almost completely blocked by the second.

The surface of the electrodes in contact with liquid crystals is specially treated to initially orient the molecules in one direction. In the TN matrix, these directions are mutually perpendicular, so the molecules line up in a helical structure in the absence of stress. This structure refracts light in such a way that before the second filter its plane of polarization rotates, and light passes through it without loss. Except for the absorption of half of the unpolarized light by the first filter, the cell can be considered transparent. If a voltage is applied to the electrodes, the molecules tend to line up in the direction of the field, which distorts the helical structure. In this case, the elastic forces counteract this, and when the voltage is turned off, the molecules return to their original position. At a sufficient field strength, almost all molecules become parallel, which leads to the opacity of the structure. By varying the voltage, you can control the degree of transparency. If a constant voltage is applied for a long time, the liquid crystal structure may degrade due to ion migration. To solve this problem, an alternating current is applied, or a change in the polarity of the field with each addressing of the cell (the opacity of the structure does not depend on the polarity of the field). In the entire matrix, it is possible to control each of the cells individually, but as their number increases, this becomes difficult, as the number of required electrodes increases. Therefore, addressing by rows and columns is used almost everywhere. The light passing through the cells can be natural – reflected from the substrate (in LCD displays without backlight). But more often an artificial light source is used, in addition to independence from external lighting, this also stabilizes the properties of the resulting image. Thus, a full-fledged LCD monitor consists of electronics that processes the input video signal, an LCD matrix, a backlight module, a power supply, and a housing. It is the combination of these components that determines the properties of the monitor as a whole, although some characteristics are more important than others.

What are the most important characteristics of LCD monitors?

  • Resolution: Horizontal and vertical dimensions expressed in pixels. Unlike CRT monitors, LCDs have one, “native”, physical resolution, the rest are achieved by interpolation.
  • Dot Size: The distance between the centers of neighboring pixels. Directly related to physical resolution.
  • Screen aspect ratio (format): The ratio of width to height, for example: 5:4, 4:3, 5:3, 8:5, 16:9, 16:10.
  • Apparent Diagonal: The size of the panel itself, measured diagonally. The display area also depends on the format: a 4:3 monitor has a larger area than a 16:9 monitor with the same diagonal.
  • Contrast: The ratio of the brightness of the lightest point to the darkest point. Some monitors use an adaptive backlight level and the contrast figure given for them does not refer to image contrast.
  • Brightness: The amount of light emitted by a display, usually measured in candela per square meter.
  • Response Time: Minimum time required for a pixel to change its brightness. Measurement methods are ambiguous.
  • Viewing angle: the angle at which the drop in contrast reaches the specified value is considered differently for different types of matrices and by different manufacturers, and is often not comparable.
  • Matrix type: LCD technology
  • Inputs: (e.g. DVI, D-Sub, HDMI, etc.).

What are LCD monitor technologies?

LCD monitors were developed in 1963 at RCA’s David Sarnoff Research Center, Princeton, NJ.

Main LCD technologies: TN+film, IPS and MVA. These technologies differ in the geometry of surfaces, polymer, control plate and front electrode. Of great importance are the purity and type of polymer with liquid crystal properties used in specific developments.

The response time of LCD monitors designed using SXRD (Silicon X-tal Reflective Display) technology has been reduced to 5 ms. Sony, Sharp and Philips have jointly developed PALC (Plasma Addressed Liquid Crystal) technology, which combines the advantages of LCD (brightness and richness of colors, contrast) and plasma panels (large viewing angles along the horizon, H, and vertical, V, high refresh rate). These displays use gas-discharge plasma cells as a brightness control, and an LCD matrix is ​​used for color filtering. PALC technology allows you to address each display pixel individually, which means unsurpassed controllability and image quality.

Computer LCD monitor device

Hello, dear readers of the blog. Today we will talk about the device of a liquid crystal (LCD) monitor, more precisely about its display. After all, it is the monitor screen that is the place that we look at the longest when working at a computer.

I must say that modern liquid crystal monitors are largely different from their “predecessors” – CRT monitors (monitors with cathode ray tubes), which are no longer sold anywhere. In general, cathode ray tube monitors began to actively disappear from the shelves of electronics stores starting from the year 2007. And this was due to a number of reasons, which will be discussed below.

Sooner or later it was bound to happen, I mean the mass transition to liquid crystal monitors, despite the skepticism of most users who already own CRTs. Indeed, the first models of LCD monitors had a number of shortcomings that modern models are deprived of, and the main drawback was probably very small viewing angles, mostly horizontally. The picture was inverted and went into the negative literally at the slightest deviation of the head from the position, when the gaze fell strictly perpendicular to the plane of the screen.

The second argument “in favor” of monitors with cathode ray tubes was that LCD monitors at first had a really short matrix response time, and this was noticeable to the naked eye when a dynamic change of picture (for example, when watching a movie) was accompanied by all sorts of loops and artifacts on the screen.

But why, despite the “dampness” of the then LCD monitors, they still gained mass popularity? I think the fact is that CRTs were also not without flaws, they had large dimensions, often their depth (thickness) was approximately equal to the diagonal of the screen itself. In addition, prolonged exposure to them led to rapid fatigue, mainly due to flicker and intense electromagnetic radiation. Well, since progress is in the direction of reducing devices and their technological improvement, it would be logical to predict the popularity that LCD monitors have today.

The operation of a CRT monitor is based on a special glass tube with a vacuum inside. Also, inside the glass flask there are electron guns that emit a stream of charged particles (electrons).

These electrons cause the dots of the phosphor, which is covered with a thin layer from the inside of the front wall of the cathode ray tube, to glow. That is, the energy of electrons turns into light, and these very luminous points form an image.

How the LCD monitor works is completely different. There are no more tubes here, and the image is formed in a completely different way. Liquid crystal displays already have in their name an indication of what is used to create an image on the screen. Yes, yes, it is liquid crystals, which were discovered back in 1888, that play a key role in shaping the picture.

The LCD monitor is more like a layer cake, each layer has its own purpose. So, we can select several layers that make up our monitor.

The first layer is the LCD backlight system, it can be made using cold cathode fluorescent lamps or LEDs. The second layer is a scattering filter, which allows you to increase the level of uniformity of the illumination of the entire matrix. Next comes the first vertical polarizing filter, which passes only vertically directed light waves. The fourth layer is the matrix itself, which consists of two transparent glass plates, between which there are molecules of a polarizing substance – liquid crystals. The fifth layer includes special color filters responsible for the color of each subpixel. Well, the last layer is the second, already horizontal polarizing filter, which, as you probably guessed, only allows horizontal waves to pass through. That’s the whole LCD monitor device. Let’s take a closer look.

In a liquid crystal matrix, each crystal is responsible for a specific point in the image on the screen. When the monitor is working, the light from the backlight system passes through a layer of liquid crystals and the viewer sees a kind of “mosaic” of pixels painted in different colors. Each pixel is made up of three sub-pixels, red, green and blue.

With these three basic colors, the screen can display up to 17 million different shades of colors. This color depth is achieved by varying the amount of light passing through each pixel. 17 million possible combinations – 17 million possible colors.

There is even a video showing the pixel structure of an LCD monitor in close-up.

Any light, as you know, has a direction, since it is also an electromagnetic wave, it also has polarization. The beam can be vertical, horizontal, have any intermediate angle.

Very important, considering that the first filter only allows vertical beams to pass through. The radiation passes through each sub-pixel and reaches the second polarizing filter, which passes only horizontal rays. In other words, not all of the light emitted by the backlight system is able to reach the user.

Crystals change the polarization of the light wave so that it passes through the second filter. In general, liquid crystals are an extremely interesting substance. Their molecules really behave like the molecules of a liquid substance, being in constant motion. But as it should be for crystals, their orientation remains unchanged.

The orientation of the crystals changes only under the influence of an electric field. When this happens, the substance begins to change. It is possible to selectively change the orientation down to the sub-pixel. That is, the crystals play the role of tiny optical lenses that change the polarization of light waves.
