The Essential TV Buying Guide

The humble television is the ultimate home comfort. For years we have relished the thought of coming home and sitting down in the living room or relaxing in our bedrooms and enjoying one of our favourite TV shows. When it comes to buying a television, it can be difficult to decide what TV is right for you, after all, there are so many makes and models to choose from. Gone are the days where TVs were a similar size and did the same things, in the modern day, very few TVs are built the same, and now they come in all designs and sizes. Below, we are going to help you to make buying that new television super easy, with a handy buying guide that will discuss the essentials that all good TVs should have, the must-have accessories, and we will answer that all-important question; does size matter?

The Essentials

When it comes to buying a television, there are a couple of things that you should be looking out for. Here are three important features that every modern TV should have:

Smart Connectivity: Some televisions come with smart functionality (or web-enabled capabilities), which allow users to stream content online directly through the television without having to hook up another device like an Apple TV. However, most televisions should at least have some form of smart functionality and allow you to change between regular television and the likes of Netflix/YouTube/Now TV.

Quality Resolution: The screen’s resolution is measured in pixels (e.g., 1080p or 4K) and determines how clear an image will appear on the TV when watching movies, playing games, or even looking at photos from your phone. A higher number will result in crisper images and allow for more detailed gameplay when using consoles like Xbox One S/ PS5 and Nintendo Switch. So if you are a gamer or want to get the absolute most out of your console, then a TV with a higher resolution output will be the best choice. Just remember that it will likely come at a cost.

Refresh Rate: The refresh rate is the number of times per second that your TV can take an image, process it and put it on display. Most TVs today come with a 60Hz (60 images per second), which means you’ll see 60 individual images every single second. That’s good enough for movies and most games but may result in undesirable side effects for fast-moving objects on the screen. If you are looking for a television with an optimal refresh rate, consider a 120Hz or a 240Hz TV.

Does tv Size Matter?

This will sound like a bit of a cop-out, but the answer is that it depends. Primarily, it depends on space. If you have a small living room or bedroom, then you are probably not going to want to fill it completely with a 72-inch television. In that instance, size matters because you are looking for something a little smaller and more scaled back.

However, if you are looking to add a television to a larger room, then the size will likely be no issue, and then it is all about what you are willing to pay. The size of the TV does also not indicate the quality of the TV. In fact, many of the best televisions that we stock in store are between 32- 55 inches. You don’t need always need to be spending the big bucks to get the best quality.


What good is it buying a brand-new television if you are not going to add a little something special to it? Both in-store and online, we have a large range of television accessories that are inexpensive and indispensable. Here are some of our favourites:

We stock a stylish and modern Sky Q voice-controlled remote in-store that will help you to locate your favourite shows, games, or movies.

What size TV should I get?

The size of the TV should be proportional to the size of the room and the viewing distance. A general rule of thumb is to have the viewing distance be about 1.5 to 2.5 times the diagonal screen size.

What is the best brand of TV?

There is no one "best" TV brand, as different brands may excel in different areas such as picture quality, design, or smart features. It's important to read reviews and compare specifications to find the TV that best suits your needs and budget.

What is the difference between LCD, LED, and OLED TVs?

LCD (liquid crystal display) TVs use a backlight to illuminate the screen, while LED (light-emitting diode) TVs use an array of LEDs as the light source. OLED (organic light-emitting diode) TVs have individual pixels that emit their own light, allowing for true black levels and wider viewing angles.

What is the resolution of a TV?

The resolution refers to the number of pixels on the screen. Common resolutions include 720p, 1080p, and 4K (also known as Ultra HD).

What is input lag?

Input lag is the delay between when a signal is sent to a TV or monitor and when it is displayed on the screen. This delay is caused by the processing that takes place between the signal being received and the image being displayed. Input lag can be a critical factor in gaming and other interactive applications, as high input lag can cause a delay between a player's actions and the corresponding on-screen response, making the game feel sluggish and unresponsive. Therefore, gamers often look for displays with low input lag, which means that the delay between input signal and display is minimized, resulting in a more responsive and enjoyable gaming experience.

What is HDR?

HDR (High Dynamic Range) is a technology that allows for a wider range of brightness and color, resulting in more realistic and vivid images.

What is the refresh rate of a TV?

The refresh rate of a TV refers to the number of times per second that the screen is redrawn or refreshed. It is usually measured in Hertz (Hz) and represents the number of frames that the TV can display in one second. A higher refresh rate can result in smoother motion and less motion blur, making it particularly important for fast-paced content such as sports, action movies, and video games. Some TVs also offer variable refresh rate (VRR) technology, which synchronizes the display's refresh rate with the output of the gaming console or PC, resulting in even smoother and more responsive gameplay.

What is a smart TV?

A smart TV is a television that can connect to the internet and access various online services, such as streaming video and music apps, social media, and web browsing.
