Crucial parameters of LCD

What are the things you need to look for when you are getting a monitor? Who can tell you better than a professional tech person that suits your need? Let’s look at the some of the most crucial parameters defining the quality of LCD you should look for through the eye of a pro tech.

Note that as a person relying on the quality of the graphics and comfort of displaying professionally, you should be particularly careful while getting an LCD monitor. At the same time, there is no need to pay to much for things that seem to be promising, however, they do not add any practical value to your monitor.


This is something for instance, a 2560 x 1440 resolution describes the number of pixels on the display. Breaking it down, 2560 across the row and 1440 pixels across column wide. All of the LCD monitors are designed to run a single native resolution, meaning you cannot run these monitors higher than their native resolution and also running lower than the native resolution would cause a disgusting degradation of the image quality. Always set the monitor at its native resolution.

Note, size does not matter. Two of the same monitor in terms of physical sizes may have different native resolution.

The number of pixels arranged are called the aspect ratio of the picture. A typical widescreen monitor has an aspect ratio of 16:9 which is 1920 x 1080.


This parameter determines the brightness of your monitor. Brightness is measure in nits. LCD panels goes from 100 nits to over 1000 nits and more on the high end monitors. Average monitors have 300 nits.

Viewing angle

LCD panels gets limited with the viewing angle. Viewing angle means how much you can see from the side or any angle other than centre. TN panels have a shorter view of roughly 70 degrees and IPS monitor provide roughly 178 degrees of angle, which is one of the reason why lot of consumers look for IPS monitors. Still, TN has its own use case as well.

Response rate

LCD panel’s response rate determines the amount of time it takes for all of the sub-pixels on the panel to change from one state to another state. LCD response rate is measure in milliseconds (ms).The lower the response rate the better.

There are more aspects you want to dig in like Refresh Rate, Contrast Ratio, Colour depth and you are good to decide your own monitor not relying on anyone else but keeping an open mind always pays off.
