Type of monitors & Their Uses: Everything Explained

By Arindam Roy

What type of computer monitors are there?

There are different types of computer monitors. These include LCD, LED, and CRT.

LCD monitors, which stands for Liquid Crystal Display, make up the majority of the market in the United States with over 50% of computers using this type. LCDs offer bright colors and at least one built-in speaker for sound output. They come in a variety of sizes–including widescreen with aspect ratios ranging from 4:3 to 16:9–and have resolutions as high as 1920×1200 or more (1080p). There are also touchscreen LCD monitors available; though their use is limited to a few specific cases (mostly touch-sensitive kiosks).

LED monitors, which stands for Light Emitting Diode, are currently the fastest growing type of monitor. They are known for having very good contrast ratios and high resolutions. While LED panels produce similar brightness to LCD panels, they are able to outlast their LCD counterparts by up to 10 times or more.

CRT monitors (Cathode Ray Tube) were the standard computer monitor hardware used from the late 1980s until about 2006. They’re still available but they’re not as common as LCD monitors–particularly after Microsoft released Windows XP which added support for DVI connections (used by LCDs).

What’s the difference between LCD, LED, and CRT?

LCD monitors use liquid crystals to create an image. CRT monitors use electric charges behind your screen to create the image. Some of the advantages of LCD monitors include: slightly higher resolutions, better color quality, local dimming (which can make darker colors appear darker), wider viewing angles (not visible on all screens), wider aspect ratios (more viewing area per inch), up to 3x brighter (extremely bright) colors than they offer on CRTs.

LED monitors use LEDs to create an image. LED panels have better contrast than CRT monitors and produce colors as bright or brighter than LCD panels can. Some of the advantages of LED monitors include: less motion blur, less energy consumption, better response times (less ghosting/blurring), shorter lifespans than LCD monitors, more energy consumed by LCD panels than LED panels.

What resolution should I get?

One of the most common questions asked is “how high a resolution screen should I get?” Resolutions for computer screens are listed in lines. The higher the number of lines in a display (the greater the resolution), the clearer image you get. A monitor with one line per pixel will have a very pixilated display and lower resolutions are better for games and movies and high resolutions are best for spreadsheets and word processing.

A common resolution is 1024×768, which is the standard resolution for computers sold in the U.S. other than desktop computers (which are usually 1600×1200). It offers a 16:9 aspect ratio of 1366×768 resolution, which is higher than many people’s current TV sets (1920×1080). Resolution for older Windows operating systems is 800×600. In millions of pixels per square inch, 1080p is one million pixels divided by 1080 lines per screen (which equals 94 pixels per line), and 1920X1080 is one billion divided by 2160 lines per screen (which equals 70 pixels per line).

Resolution is just one factor in your decision for what type of monitor to get. Many other factors will come into play. Make sure to examine the monitor’s features for those other factors. Also see our article on [CRT vs LCD, what’s better?]:type of computer monitors & their features in brief

What do I have to understand about LCDs?

As mentioned previously, LCDs use liquid crystals and LEDs use light beams. The more liquid crystals you add to an LCD, the brighter it gets. The more LEDs you add to an LED, the brighter it gets.

LCD panels come in two different technologies: twisted nematic (TN) and in-plane switching (IPS). Twisted nematic displays are known for having fast response times while IPS displays are known for their colors and wide viewing angles. However, now better TN panels have started to become available which can match the viewing angles of IPS panels.

LCDs are usually measured by a scaler unit that controls the pixels’ brightness. The lower the response time on an LCD, the better image quality you get–but this also causes more blurring of objects when they’re moving fast. Contrast ratio is how much white you get compared to the black. The higher the contrast ratio, the more vibrant your colors will be. Manufacturers have now started using RGBW panels which can deliver a wider range of color than a standard RGB monitor without changing resolution through the use of dithering (additional pixels that are indistinguishable from the original).

The typical lifespan for a flat panel display is just over 3 years. It’s recommended to replace your monitor when it reaches 2 years of age at most and 4 years if you want an extended life. While these specifications do vary, many monitor manufacturers state these lifetime figures in their warranty documentation. Some monitors can have their lifetime extended by replacing the backlight–the LED’s that generate light for an LCD display.

Monitor overview:

A monitor, also known as a display, is an output device that presents information. It can show images and text in a physical form. A type of display device, it produces visual images of objects or data from its own memory or from another computer source.

Types of monitors:

CRT (cathode ray tube) – The earliest kind of computer monitors were CRT’s. They use cathode ray tubes to produce an image for the user to see on the screen. Today, they are still very common and popular, mostly in older terminals. CRT’s have the “tube” being the monitor itself due to the glowing phosphors that are placed inside it to create an image. Currently, CRT’s are being slowly phased out for newer technologies (such as LCD and OLED) however they still remain very popular.

LCD (liquid crystal display) – The LCD is another type of computer monitor. An LCD is a flat display made from liquid crystal instead of glowing phosphors. It is also known as a flat panel display, or FPD for short. This technology replaced the CRT technology for monitors in 1981 on personal computers and later saw widespread use on laptops beginning in 1997.

OLED (organic light emitting diode) – OLED stands for organic light-emitting diode. The OLED is a light source that exhibits properties of organic compounds and emits visible light when operated at an appropriate voltage. It can be used on a large scale in television screens and other displays. Due to the liquid crystal properties of the display, it can also be thin and lightweight. The OLED does not require backlighting, so it consumes less power than traditional LCD or plasma displays. It is also more resistant to screen burn-in, which means the new image will last much longer than existing ones if the monitor stays turned on for an extended period of time.

Plasma monitor – A plasma monitor is a flat panel display that has multiple thin glass or plastic layers and uses fluorescent lamps with ionized gases to create images. Plasma monitors are the most commonly used displays in televisions. Compared to other display technologies, they have good contrast ratios and are better for displaying fast-moving images because pixels can be switched off faster. They consume more energy than LCD monitors and newer types of liquid crystal displays. Some plasmas also suffer from screen burn-in if their pixels are left on for an extended period of time.

LED – LED stands for light emitting diode, which is one of the many kinds of diodes used in electronic components. A diode is an electronic device that allows electricity to flow through it in only one direction. LEDs are commonly found in traffic lights and vehicle tail lights among other things. Also used in computer monitors, they have a very low power consumption rate since they do not require as much processing power as LCDs or plasma displays.

All of the different kinds of computer monitors share similar features, including:

Screen size – A measure of the diagonal length of a liquid crystal display screen, measured from one corner to the opposite corner. Screen size can also refer to a television set’s physical dimensions, taking into account both its width and height, but typically it refers to the diagonal measurement.

Resolution – A measurement of the amount of pixels on a screen. It is often represented by a three-digit number, such as 1280 x 1024 or 1440 x 900. The first number represents the width of the image in pixels while the second number represents the height. Resolution is determined according to how many individual pixels appear on a screen, and it can also be affected by factors including color depth and dots per inch (or dpi).

Brightness – Brightness refers to the amount of light emitted by a display. Larger values for brightness mean that more light will be given off by a monitor when it is turned on at its highest capacity.

Contrast ratio – Contrast ratio is the difference between the darkest and lightest areas on a display screen. The contrast ratio for a particular monitor can vary depending on how it calibrates its backlight. A higher contrast ratio means a better viewing experience.

Refresh rate – How fast the monitor can refresh an image or frame when it appears on the screen. It is measured in Hertz (Hz). The higher the refresh rate, the more times per second an image refreshes onscreen. Some monitors have high refresh rates while others have low refresh rates, which may affect how quickly text appears onscreen.

Anti-glare or anti-reflective coating – Anti-glare or anti-reflective coating is a coating on the screen that brings the best image possible. It reduces glare from the monitor screen and minimizes reflections, which can be seen on other displays. The coating can also make the screen less reflective and thus less bright when it is used outdoors. On some types of display screens, such as plasma screens, it is necessary to use this protective layer.

Connectivity – A port on a monitor that allows images or other information to be exchanged with a computer system’s data bus during the process of displaying images onscreen. Connectivity is typically determined by Universal Serial Bus (USB), IEEE 1394, or Digital Visual Interface (DVI) cables.

Physical features – A computer monitor’s physical features can affect its performance, ease of use and user comfort. Features include integrated speakers, height adjustments for monitors that have a stand, pivoting functionality for monitors with tilt-and-swivel stands, and aspect ratio. The aspect ratio is a set of numbers in a rectangle that determine the screen’s image size in relation to its width and height. The most common aspect ratios are 4:3 and 16:9. In general, the higher the number on either side of the ratio, the larger the image displayed onscreen will be.

Video input – A port on a monitor that allows it to connect to a computer system’s data bus when images are displayed for viewing. The port is typically used with a cable, such as an S-Video cable or a DVI cable.

Display size – Physical dimensions of the entire screen, taking into account both the height and width of the display.

Warranty – This refers to a period of time during which manufacturers guarantee that their products will be free from defects and work properly if they are used in accordance with product use guidelines. Most manufacturers offer warranties on their monitors ranging from 90 days up to three years. Monitors are sometimes sold with additional warranty protection provided by third parties. The length of the warranty and how it is handled relative to the monitor’s purchase price and related features will vary from manufacturer to manufacturer.

Additional information – Information about the model number of a monitor, its specifications in terms of resolution, technology used and so on. For example, information may be provided regarding rating for various types of screens or technology used.

IPS (In-Plane Switching) – A technology used to measure the distance between individual pixels on a screen in order to create high quality images. This measurement is referred to as pixel pitch. In general, the smaller this measurement, the higher quality images can be displayed on screen. The most common features are 6-bit and 8-bit drive controllers and 4:4:4 sub-sampling.

Pivot – Allows a monitor to rotate on its base in order to change the vertical viewing angle of the screen by 90 degrees or more. This allows the user to adjust the location of the screen as needed for optimal viewing comfort.

Rear projection – A technology that projects images in front of a screen that is placed behind a similarly positioned mirror. This technology uses two projectors which each output an image onto film placed behind a screen with interlocking pins which can be moved to change the angle of projection. The size and shape of the screen are adjustable but are typically fixed at 27 inches diagonally.

Frequently Asked Questions:

What Is the Difference Between a Display Port and HDMI Port?

Both types of ports allow you to connect your monitor to your computer, but while Display Port is backwards compatible, HDMI is not. With an HDMI port, your monitor can be connected to other HD devices such as a games console or home theater system. In addition to this, you can use an HDMI cable to connect more than one monitor at once. But with a Display Port, only one monitor will be able to communicate with the computer at any given time. 41) How Can I Connect Multiple Monitors at Once?

You can connect multiple monitors of different sizes through various methods. For example, if you have a single video card, then you can connect them through a splitter. This is the cheapest method but isn’t ideal if you need all of your monitors to be in sync with each other. Instead of doing this, you can go for a more expensive option such as buying an extra video card that will allow you to connect two or more monitors at once. 42) What Kinds of Ports Do I Need to Connect My Monitor?

When connecting your monitor, you need to make sure that it has the right ports on its side. Depending on what kind of connection that your computer has, you’ll want your monitor to have either Display Ports or HDMI ports so that they’re able to communicate properly with one another.

What Are the Different Types of Input Lag?

When talking about input lag in a monitor, most people confuse it with motion blur . In layman’s terms, motion blur is the effect of objects moving quickly being blurred out when they switch from one angle to another. While motion blur can be an issue with slower screens, it is not a form of input lag that’s caused by the screen or graphics card. Instead, input lag refers to delays between when an action is performed and when it appears on screen. Every monitor will have some level of input lag, which is measured in milliseconds. If your monitor has a high input lag, then it can cause you to miss out on important moments while playing fast-paced games. 49) How Do I Test My Monitor for Input Lag?

While this is a very technical subject to talk about, it is actually very easy to test your screen for input lag. All you need to do is use a stopwatch app or similar timekeeping device and then find out how long it takes your monitor to react from the moment that an action is performed using a mouse or keyboard. To get the most accurate results possible, try doing this at the beginning and then again at the end of your work day. 50) What Is Vertical Sync (Vsync)?

Vertical Sync, or V-Sync, is a term used to describe the amount of time that a monitor takes to flush out from one frame to the other. This is extremely important for gamers who want a more fluid experience while playing their games. For example, if your monitor has a large amount of input lag when V-Sync is turned on, then it will look like there’s a lot of motion blur when you’re playing fast paced games. This can also be an issue with high framerate games as well. Thus, when it comes to gaming, you should always turn off vertical sync in order to get the best possible performance.

What Is the Difference Between Low Input Lag and High Input Lag?

Low input lag can refer to when your monitor shows slow reaction times or a delay between actions. This can occur when a graphics card is out of date and is not able to process images quickly enough, some of which are still in use in monitors. In this case, you need to choose a monitor with high input lag because it will have a faster refresh rate than those with low lag. However, as I mentioned before, this also depends on the size of your monitor. If you buy a large display that has low input lag then you might be subject to even slower speeds and transitioning. 52) What Is the Best Gaming Setup for Me?

One of the first things that you should do when looking to get a best gaming setup is reduce input lag as much as you can. To do this, you will need to buy a solid motherboard as well as a new video card. After doing this, then try updating your drivers to see if it makes any changes in your game’s performance.

What Are the Benefits of Using a Monitor with High Refresh Rates?

Monitors with high refresh rates are ideal for gaming because they eliminate screen tearing and motion blur from fast-paced video games. If you’re looking to buy a gaming monitor, then you should definitely consider going for one that has higher refresh rates.

What Is the Difference Between Vertical and Horizontal Sync?

Both vertical and horizontal sync are used as methods to reduce screen tearing when playing video games. However, while it’s possible to turn vertical sync on or off whenever you want, horizontal sync is different because it can’t be disabled in all games.

How Do I Choose the Best Monitor for My Gaming Setup?

To choose a good monitor for your gaming setup, you need to make sure that it has high refresh rates along with low input lag. Good brands like BenQ, DELL, and ASUS have monitors that are perfect for this purpose.

Why Do Monitors Vary in Size?

There are many reasons why monitors vary in size. First, it is important to note that there are different types of panels that can be used in monitors including IPS (In-Plane Switching), VA (Vertical Alignment) and TN (Twisted Nematic). Because they each have their own advantages and disadvantages with regards to viewing angles and color space coverage, the size of monitor that you choose depends on what kind of display you need it for. For example, if you need a large display that is good for multitasking, then you should go for an IPS monitor. On the other hand, if you’re looking for a larger display that’s better suited for graphics design work, then I recommend that you go for a VA panel.

How Can I Upgrade My Monitors?

If your old or oldish monitor is still working properly even after years of use, then it should be safe to replace it with a newer one. You can do this by using a sticker to cover the old part and then removing it once you’ve purchased your new monitor. But if you want to do this with multiple monitors, then you’ll probably need some extra help because it can be rather tricky. You might need some basic keyboard accessibility software or reading glasses to do this task, but it isn’t impossible to do.

How do I tell if my monitor is a true color?

You can look for information about your monitor online or at stores such as Amazon.com or BestBuy.com . You will also need to look for a tag on the back of your monitor that will tell you its type.

If you are planning on buying one online, make sure it has a tag that tells you what model/type of monitor it is.
