Glossary: 4K Resolution Technology

Aspect ratio:

Aspect ratio refers to the heights and width ratio of the image. The ratio determines how much accurately you will be viewing the exact image or video. Whether the screen covers the image in longitudinal direction or in latitude. The more it covers the latitude the better will be the view.

 Backlight bleeding:

Backlight bleeding is a deficiency in the monitor system where the screen leaks out light around the edges. That may just slump to a complete wash out of colors in that specific area. It is a norm with all the monitors, but the best ones covers it up nicely with minimal bleeding which is small enough to get noticed.


The brightness of the monitor stands for the quality of the view the monitor offers while in bright conditions. It is being measured in cd/m2 that is candela per square meter. The more it has the cd/m2 value the better would be the results monitor will have in brighter conditions.

Contrast ratio:
It is a determinant of the ratio between the brightest white and the darkest black on the screen. The higher the ratio is, better will be the picture quality. Another determinant is the dynamic contrast ratio which is nothing more than just a marketing gimmick used by manufacturers.

Color supported:

The color supported in a 4K Tv would refer to the number of shades per color could be seen. It could also be referred as color bit depth which mean the number of shades offered in that TV. The more the shades the better would be the view of the image covering all shades resulting into a life-like image.

Dynamic contrast ratio:

Contrast ratio defines the quality of an image in terms of the number of shades offered in black and white colors. The more the value the more shades would be there to provide better picture quality covering the maximum amount of light and dark shades in the picture. You can access the quality of contrast by considering the value given like this 1000:1. The more the difference is there between the two values the better would be the picture quality with a sharp distinction between light an dark shades. In 4K TVs there is a feature that makes the contrast even more sharper when the picture has scenes in the dark. And this is termed as dynamic contrast ration that justifies the ration according to the scene or image that is being seen.


A D-Sub port can be useful when you need to connect external devices to the monitor. Though it has a better alternative in the form a USB port.

Dual link DVI:

A duel link DVI stands for the DVI port that has the ability to carry the double amount of data as compared to single link port. It doesn’t mean that there will be two of them rather the capacity would be increased. It’s better for high resolution monitors to be installed with a dual link DVI to ensure high quality image and acoustic experience.

Display port:

A display port is the latest technology developed by VESA to replace DVI and VGA ports for better video transfer. It is being used to connect a video source to any display device as well as for audio transfer and connectivity.


A DVI is the digital video interface providing digital audiovisual transfer. But in the latest versions of smart TVs and monitors it has been replaced by HDMI port, which has a better result in providing quality audio-visual experience.


It is the smearing of the images which occurs when a ‘ghost’ or a trail of images go past the screen by leaving behind its impact on the screen. It could hinder in your way to enjoy the picture quality. This is countered by the response time. The quicker it is, lesser will be the ghosting element.

HDMI 1.4:

HDMI stands for the high-definition multimedia interface. Today all smart TVs. LED, LCDs and OLEDs come with an HDMI. This feature provides the TV to create high quality sounds and images through bidirectional digital signaling without distorting the actual signal from the source. It eliminates the chances of loosing data and provides secure signaling for high quality audiovisual results. The HDMI 1.4 version, provide digital signaling and bandwidth of about 10.2 Gbps without distorting the audio visual results.


HDMI 2.0 provides an interface to facilitate higher bandwidth up to 18 Gbps as compared to 1.4 that was 10.2 Gbps.


It stands for In-Plane Switching and it is the most contemporary panel capable of producing the best viewing angles. They have limited response time in comparison with the TN panels.


This property measures the brightness level of your monitor. The unit for measuring luminance is cd/m2 where cd stands for candela per square meter. So the brightness of your display is proportional to the luminance rating.

Maximum resolution:

Maximum resolution is the maximum capacity of a screen or a monitor to project a certain number of pixels which are predetermined or native to the monitor by the manufacturer, by default or the max ability to provide a quality image. If the image exceeds the maximum resolution it can distort the image quality and may not be giving the desired results.

Response time:

It defines the rate at which the colors are changed from one to the other. The unit of measuring the response time is milliseconds. It also measures the ability of the pixel to change from black to white or vice versa. The best monitors these days come with a quick response time of as much as 1 ms.

Refresh rate:

It is the rate at which the monitor display refreshes itself and the unit of measuring that is in Hertz (Hz). It gives the frequency and the higher it is; smoother will be the output on the screen.


This parameter gives an indication about the potential ability to project the pixels on the screen. The higher the value of resolution goes, sharper and finer will be the display. As an example, a 19 inch monitor can potentially display with a maximum resolution of 1280 x 1024. It means that the screen will project 1280 pixels horizontally and the 1024 pixels will be displayed vertically.

The multi-stream technology:

The multi-stream technology refers to streaming multiple videos from a single desktop. This feature can work with Display-port 1.2 enabled monitors. It can help to facilitate multitasking through an integrated set of screens for your various tasks streamed through a single source. This technology can also work with Daisy-chaining for multi monitor setup. The only need is the presence of display-port 1.2 inputs and output in all monitors to be connected to ensure that they would be able to carry out multi-streaming.


It stands for Twisted Nematic. It is the pioneer panel system to be used with the desktop monitors. They are still preferred for its low cost by many renowned manufacturers. They have the capacity of giving the fastest response time, which is a mandatory requirement for the hardcore gamers. The viewing angles are limited for TN panel which is a major worry for the users.

Viewing angle:

Viewing angle is measured in degrees and it defines the angle at which you can view the screen either from the bottom, top or the sides. The maximum viewing angle is that point which ensures that the contrast or colors on the screen wouldn’t be compromised. All manufacturers have different claims which are mostly exaggerated.

The viewing angle for any high definition monitor or screen is the exact distance where a person can view an image without blurring the picture, without lowering the contrast ratio and also without getting fainted or dark at any position. For a flat screen 180 degree would be the best to have a great visual experience.


VA stands for Vertical alignment which is another type of panel that provides a good compromise between the TN and IPS panel types. It is capable of giving wider view angles than the TN type but narrower if compared with IPS panels.


USB port either USB 2.0 OR A USB 3.0 is there for interconnecting two or more audio visual options. The difference between the 2.0 and 3.0 is the quality and speed of data transfer between the two devices. You can attach a USB to the USB port on the monitor and enjoy the High definition data translation easily.

4k and 5K resolution:

4K and 5K resolution stands of 4000 pixels and 5000 pixels respectively. It’s a fact that when there are more pixels that are being projected and used to provide the image the sharper will be the image. For this reason the 5K resolution provides better, detailed and clear results as compared to the 4K with 4000 pixel resolution monitors as it comprises 5000 pixels and the images thus seen are more detailed and sharp.
