Best 48 Inch 4K TV- An Overview

Upgrading from a 40 or 43 inches TV to a 48 inch TV is an excellent decision, coupled with the fact that it is a 4k TV.

One of the greatest advantages of a 48 inch TV is that it allows multiple viewers to see the screen’s content simultaneously and from any viewing angle.

Another major benefit is the display resolution.  

A 4k screen delivers twice full HD screen resolution.

Also, it’s clearer and brighter than the most common 1080p.

Even more, TVs in this category are particularly smart TVs.

Bottom line, you’ve already decided on the size and screen resolution of the TV you want to buy.

Hence the reason you’re specifically searching for the best 48 Inch 4k TV- good job.

However, besides the screen size and resolution, other things make a good TV that will fit your needs.

What are these things?

See the next section.

Important Consideration For The Best 48 inches 4K TV

So, the idea of buying a TV is beyond the size and resolution.

Other qualities make a TV the best and worth your money. 

Some of these include;

Screen Type

There are four major TV screen types.

They include; LCD, LED, OLED, and QLED.

Liquid crystal diode (LCD) is the oldest of all the screen types.

It makes use of fluorescent for backlighting.

Light-emitting Diode (LED) is the second screen type.

It is a common and the most popular screen type.

It makes use of light-emitting as its backlight.

However, LED display is far better than LCD.

Although both display well on the screen, OLED supersedes both screen types.

Organic Light-emitting Diode (OLED) uses organic material that emits light in place of backlight and is placed between LED panels.

This gives the picture a stunning contrast rate.

Finally, the QLED is becoming more common these days, and it makes use of Quantum dots for backlighting.

However, QLED is still the same as LCD TVs.

Moreso, QLED and OLED screens are triple-layered.

Lastly, they prevent sun glare/reflections on the screen.

TV Type

You need to consider the type of TV you want to purchase.

Specifically, you can choose from the two TV types available depending on where you are placing your TVs.

They are Flat TV and Curve TV.

Flat-screen TV has been the most popular TV type.

However, in recent times, we have seen more curved TV screens.

Overall, where you’ll be placing the TV will determine the best type of TV to buy, and each TV type has its advantage over the other.

Firstly, a curve screen TV looks beautiful and gives more depth.

Consequently, making images appear more realistic and wider.

Also, it gives you a more immersive view.

On the downside, you can’t mount a curved TV on the wall. 

They’re best placed on a stand or a table.

Also, viewers can only enjoy a curve screen TV while sitting in the middle to watch the TV. 

Therefore, viewers from the side might not enjoy the TV like the person sitting right in the middle.

On the other hand, the flat-screen TV has always been the most popular screen type.

First, you can mount it on the wall or place it on a table/stand. 

Also, it allows people to view the screen conveniently from different angles.

Ports/ Connectivity

The most important thing people look away from is the number of ports on the TV.

Ports and connectivity are very important as well.

If you have a lesser port on a TV, you will enjoy a minimum of what the TV can offer.

Alternatively, if you have a good number of ports, you will enjoy optimal performance from the TV.

The major ports you need to look out for are the HDMI ports.

At least 3 to 4 HDMI ports will fit in for a 48 inch 4k TV.

Also, USB ports are important for transferring contents from your devices to the TV.

Furthermore, Ethernet port, Composite, AV port, RF cable port, etc., are also important ports to have.

In addition to that, a Wi-Fi and Bluetooth-enabled TV will help you to connect to the internet and transfer files from your smart devices to your TV.

Having a Wi-Fi connection will also give you access to internet support services like Netflix, Hulu, Vudu, Youtube, Amazon prime videos, etc.

Finally, Google Assistant and Amazon Alexa give you the privilege of controlling your TV using your voice.

Port Positioning

The positioning of the port depends on where you want to place your TV.

You should consider a TV with the ports arranged on the side if you’re mounting your TV.

This will make the ports easily accessible with the TV mounted on the wall.

Moreso, if you plan to place your TV on a stand, then with the ports arranged on the side or behind the TV, you’ll have no problem accessing them.

Either way is okay for stand mounting TVs.

Sound Technology

In recent times, gamers, music, and action movie lovers demand more good sound.

Fortunately, manufacturers have been able to meet this need by including some of the best sound technology in the design of their products.

They include:

  • DTS:X,
  • Dolby Atmos, and
  • Acoustic surface sound.

Technically, DTS:X is of higher bitrate, and it should offer better audio.

However, Dolby Atmos is more advanced and is capable of using lower bitrate to produce higher sound.

Meanwhile, the Acoustic surface sound has mostly been used by SONY brands whereby the whole screen is turned into a giant speaker.

Picture Quality

A TV of 48 inches with 4K screen resolution will have thousands of pixels to deliver clear, detailed, and colorful images.

However, other than the display resolution, the refresh rate, motion rate, contrast ratio, and aspect ratio also contribute to the picture quality displayed on the screen.

Firstly, the refresh rate and the motion rate work together.

The motion rate doubles the refresh rate- e.g., a motion rate of 240 Hz is equivalent to a refresh rate of 120Hz

The refresh rate is the number of seconds an image can change to another without blurring.

Refresh rate is measured by Hertz (Hz), and the higher the Hertz, the better.

At least 60 Hz to 120 Hz will deliver excellent picture quality for gaming and fast-action movies- anything less will be bad.

Next is the contrast ratio,

Ideally, a contrast ratio of 3000:1 is best for an impressive picture quality- anything lesser than this might give a mediocre picture quality.

To be precise, a contrast ratio of 3000: 1 will have deep black levels, while anything lesser will display dark gray images.

Overall, the higher the contrast ratio, the brighter the picture quality.

Finally, we have the aspect ratio.

Aspect ratio is the measurement of the width to height of the screen.

The standard is a 16:9 aspect ratio.

Anything less will result in an overstretched or distorted image with blank spaces around the image.
