Best TV Resolution

Best TV Resolution

Purchasing a TV for your home means a huge investment for any household. As such, it is extremely important for any buyer to perform a good level of research before buying a new TV set.

One of the most important factors that need to be considered is resolution. This especially applies when you are buying modern versions of LED TVs.

LED TV Basics

LED TVs are a specific kind of LCD TV, a kind of television set which has been designed by sandwiching liquid crystals, which are gel-like materials, in between glass panels.

A liquid crystal comes with a twisted molecular form which will untwist in unexpected ways as electrical current is being applied to it. Usually, LCDs are transparent.

However, as current is applied, light is bent, with some light passing through the upper glass layer. In certain situations, there is no light passing through.

This is basically how different color shades are being produced on the screen. In order to come up with colors, smaller filters in red, green and blue are placed on top of the glass panel.

Each group of the three colors is referred to as a pixel. When pixels are combined, they create images displayed on the screen. LCDs are not able to produce light on their own.

LEDs and TV Screen Lighting

An LED refers to a diode which produces light by means of vibrating electrons using a semiconductor.

The use of an LED is often more advantageous because it is brighter, more energy efficient and relatively smaller. Generally, there are three kinds of LED TVs.

Back-lit LED TV
Comes equipped with LEDs that are placed all throughout the rear part of the LCD display. This enables brightness in the display, creating vivid colors and a richer contrast.

Edge-lit LED TV
Contain LEDs which run within the edges of the TV screen. This means the screens are thinner and cheaper to produce than their back-lit siblings. However, these screens are prone to irregular contrast patches and brightness around the edges.

LED TVs with Local Dimming
This type of LED TV is normally found within certain back-lit LED TVs, or in other words, TVs with “Full Array LED backlighting”. The difference here is that either individual LEDs, or groups of LEDs, can be brightened or dimmed. This allows for greater control over black levels and contrast.

The Basics of Resolution

Simply put, resolution refers to the measurement of pixels. The effect that resolution has on the picture quality of a television goes beyond just the number of pixels.

Other factors also include aspect ratio, native resolution of the source, scanning type and scaling. These can have an impact on the quality and sharpness on the image that is projected on the screen.

Display Resolution

Display resolution refers to the pixel measurement on the screen. This is basically known as the native resolution.

Generally speaking, this is presented as height x width. Since LED screens come with a specific number of pixels, they can be called fixed pixel displays. What does this mean?

Basically, this means that even when you are receiving information coming from the source, the maximum detail shown is the native resolution. Similarly, as a video signal is sent with lower native resolution, it is being enlarged in order to fill the complete native resolution.

Aspect Ratio

Aspect ratio refers to the specific number which describes the ratio representing the width of a display in relation to its height.

The two primary aspect ratios that are often used in TVs are 4:3, which is the standard and 16:9, which is the widescreen ratio.

Scanning

Progressive and interlaced scanning are the two primary types of scanning that are used in TVs.

Scanning refers to the name in which a screen updates and then changes the images. This is usually represented by the letters “p” and “I” in the resolution value.

Scaling

If there is a mismatch between the source resolution and the native resolution, an image is then scaled in order to match to the TV’s native resolution.

For example, if you are watching a movie on Blu-ray, which comes with a 1080p source resolution on a 720p LED TV, the signal will automatically be downscaled to 720p.

The Importance of Resolution

When shopping for an LED TV, it is very important to identify the best TV resolution that will satisfy your needs. This can be done by considering several other factors, including the following:

Size of the Screen

Keep in mind that the larger your screen is, the more detail will be shown.

The larger the screen, you can also expect that the higher resolution is needed in order to maintain a high standard in picture quality.

Unless the source quality is really bad, or the screen is extremely large, all HD resolutions basically look the same.

Viewing Distance

Another important factor is the viewing distance. The closer a seated viewer is from a television, the more detail will be seen. Thus, the resolution should be higher as the viewer sits closer to a TV.

All this ensures for the best viewing experience. Therefore, it is important to take some measurements in your room first before anything else.

Here is a chart to give you an idea of viewing distance to screen size:

Distance from TVTV Size
4ft - 6 ft 17" - 27"
7ft - 9 ft27" - 40"
10ft - 11ft40" - 47"
12ft - 13ft47" - 56"
14ft56" >

By doing your own research before the actual day of purchase, you can come up with a well-informed decision as you have already identified the best TV resolution that you are looking for in an LED TV.
