How to select best TV to buy

This is a website guide to buy a TV. We will advise on the steps required to enable you to choose the best TV for yourself. The very first step in the TV buying process should be where you want to place the TV and where you will be sitting or lying to watch TV. You should then decide whether the TV will be mounted on the wall or you have shelf or table to place the TV. Now fix a budget on how much you want to spend on your TV.

Next you have to make an online search for TV to get an idea of the TVs available in the market and what are the going prices for TVs. The best place to start your TV buying research is the Amazon website for your country. These are the links to the general TV pages on Amazon Australia | Canada | India | UK | USA. Once you get an idea of the prices of TV models now popular in the market, it is time to go to the next steps to decide on the best TV to buy for yourself.

What kind of TVs are there?

There are only 2 main kinds of TV - The LED TV and the OLED TV. LED TVs are cheaper than OLED TV and LED TV has very good picture quality. It is only when you compare OLED to LED TV side by side that you realize how much better an OLED TV is. You have to decide for yourself whether you want to spend the extra money for same size OLED TV Vs LED TV or for the same money buy a smaller OLED TV. LED TV picture quality is by no means bad, only don't compare it with an OLED TV. Within LED TV you can pay more and get higher quality LED TVs like Samsung's QLED which stands for 'Quantum dot LED' TV. For more see our page on different kinds, types and sizes of TVs.

How to decide TV size to buy

One of the most important thing to consider before buying a TV is the size of TV to buy. The natural instict of almost everyone is to buy the biggest TV one can afford, but the best size TV to buy will depend on where you will mount the TV and how far or close you will be sitting to watch TV.

There is an optimom size for TV depending on how far you sit from the TV. People will say, for example, that with a 4K TV it is no problem sitting close to the TV, because you cannot see the individual pixels since they are packed so close together. This is wrong, there is a safe distance to sit from a TV and it depends on the angle the sides of the TV makes with your eyes. Both sides of the TV must be within the 'Visual Field of human eyes'. To quote from the reputed Sight Science website

What is the visual field?

The visual field is the area of your vision that you can perceive when you look straight ahead without moving your eyes or head. Within the visual field our visual quality is different, depending on the area- in the center of our view, where we fixate objects, text, faces etc. with our eyes, we see particularly sharp. Further to the sides we see more blurry (peripheral vision). TVIn the periphery it is most important to notice movements, so that eyes and head can be moved into that direction.

To quote again from a medical authority NCBI (US National Center for Biotechnology information) website

A normal visual field is an island of vision measuring 90 degrees temporally to central Fixation, 50 degrees superiorly and nasally, and 60 degrees inferiorly. Visual acuity increases from movement discrimination in the extreme peripheral vision to better than 20/20 in the center of vision.

So for the TV to be in our Visual Field it must be, at the most, within a 50° angle from the ceter of our forehead. For safety assume an angle of 45°. Form mathematical formula we know that at a 45° visual field the distance from TV will equal the width of the TV. The width of the TV is always less than the diagonal size of the TV. So for a safe distance to sit from TV it must at least be the same as the size of the TV. For example for a 50 inch TV you should be sitting at least 50 inches from TV, that is at least 4 feet or 1.2 meter from the TV. These are the minimum distances to watch TV, but highly recomend that you sit at a distance of at least 1.5 times the TV Size, that means for a 50 inch TV, sit at a distance of at least 6 feet or 1.8 Meters.

Other important considerations when buying a TV

Some of the other considerations when buying a TV are factors like Contrast Ratio, whether the TV has a High Dynamic Range HDR for color display, etc. See our page which explains all the technical terms used with TV specifications
