Guide to buying the monitor for the best computer based on screen resolution, size and other technical parameters

After talking about things to know before buying a new computer , let's see how to choose a monitor for the PC  and what technical parameters to consider to make a good purchase, depending on the price you are willing to pay. 

The most common monitors are the LCD or flat liquid crystal displays. 

At the same time that LCD monitors have conquered the television market, they have also become a standard in the world of monitors, quickly supplanting old CRTs (cathode ray tube monitors).
In this guide we will see  how to choose a new flat panel LCD monitor .

How to choose the monitor for the desktop PC
LCD monitors also require less power, emit far less radiation than cathode ray tube monitors and the technology allows for clearer images, higher resolutions and a flicker-free display, good for the health of eyes.

Although all monitors look the same, there are important features to keep in mind before purchase.
1) Screen size : The screen size is measured in inches, in the diagonal distance from the bottom left corner to the upper right corner of the screen.

Available sizes range from 15 to 30 inches (although super displays of over 32 inches are available) but, generally, the most common format for a desktop monitor today is 19 "or, maximum, 22".
It is not wrong to bet on a large monitor but larger dimensions require more space on the desk and the cost rises enough.

Using the computer on a large screen is especially useful for those who work with graphics programs and who must keep multiple windows open in parallel.

2) Proportions -With the disappearance of CRT monitors the most widespread proportion is certainly 16: 9, identical to that visible even on modern TV.

Whatever the activity to do (work, fun, games) the standard is now 16: 9 so even the programs are exploited better.
Some new types of proportions such as the 21: 9 (Ultra Wide) or even 32: 9 widen the horizontal space and keep the vertical space intact: they are ideal for games in 4K. and for those who work a lot with graphs, tables and spreadsheets.

3) Resolution- Resolution is the number of pixels displayed horizontally and vertically.
Higher resolutions mean sharper images, more clarity and more desktop space for icons and programs; in contrast to increasingly higher resolutions, the text becomes much smaller and more difficult to read.

So, before thinking that more pixels = more quality, it is convenient to reflect on the way you use the computer, if you use it to work with text documents or if it is mainly used to watch videos and images.

The minimum resolution for all modern desktop PC monitors is Full HD (1920 x 1080 pixels), but monitors with 4K Ultra HD resolution (3840 x 2160 pixels) are becoming more widespread in order to achieve double the detail and resolution.

4) Contrast: Ratio The contrast ratio describes the difference between the brighter white and the darkest black that the LCD monitor can display.

Higher contrast ratios show clearer whites and blacks, thus improving the color rendition of the monitor in any scenario.

The best native contrast ratio you can have on a modern LCD panel is 1,000: 1.

We can also not use this parameter to choose between two monitors, since we often use dynamic contrast (via software) to obtain a better contrast in an artificial way.

5) Brightness: LCD monitors have a large back panel that provides all the light needed for the LCD panel; in the most recent models the backlight panel is equipped with LED lamps, which consume much less and allow a good result in terms of brightness.

The brightness is measured in candles per square meter (cd / m2).

A value of at least 300 cd / m2, ie a higher brightness, and is ideal for watching movies or playing games on the computer.

For office work and surfing on the Internet, a ratio of 200 - 250 cd / m2 is more than good.

6) Viewing angle: For the viewing angle of the image, the LCD technology has taken a clear step back from the cathode ray tubes, because the more we move away from the center the more the colors fade and the image becomes much more white.

This parameter is relative because if we use the monitor only with the PC, we will always look at it in front and never on the side (which instead can happen with a TV).

Regarding this topic, we can mention the difference between TN and IPS monitors.
The TN technology is the most widespread and the most economical of TFT screens and is characterized by a low angle of view and a low contrast ratio.

The most expensive evolution is the IPS monitor with more vivid colors and greater viewing angle.

7) Doors: A monitor must be connected to a computer and possibly to other devices, so it is important to know the number of ports that can be used.

In another article I wrote a guide on cables, ports and connectors on the computer .
For a standard monitor we need to check that there is at least one HDMI port and a Display Port port, both well supported by dedicated video cards and integrated chips on the latest generation motherboards.

If the PC is a bit 'old it is convenient to check that there is also an old-fashioned "backup" port that is DVI and VGA (the latter fall almost completely out of use).

8) Integrated audio

Thanks to the HDMI and Display Port ports the PC audio can be carried on a single cable along with the video, so many monitors have built-in speakers.

Our advice is never to rely too much: the speakers integrated into the monitors are really small and rarely sound so good that they can replace a small 2.1 sound system (practically never!).
So if the space is little we can consider a monitor with integrated audio, otherwise it is always convenient to bet on the separate speakers.

8) Conclusions: In summary, when you go to buy a new computer monitor, you must first consider the dimensions, proportions and resolution.

In the next step you can compare all the models available in the store to check the other features and, above all, look at the contrast ratio, brightness, and available ports.
