We will help you step by step to choose the TV’s screen size, technology, features that match the size of your room and budget.

Why do I write a tv buying guide?

In my house there are two TVs, I bought a TV in the living room, a kitchen. Did I ask many questions before buying the tv, such as What is the best tv in the living room and kitchen? the best brands to buy? what size tv should I buy and how to choose the right size tv? and more …

Then I tried to imagine myself want a tv. I’m starting the search for tv buying guide and I’ve read a lot of tv buying guide, however, most of us just talk about one aspect that can not meet all of my needing. I realized I had fallen into a mess because there is so much buying guide articles, everything made me mess up, especially when I’m not a technical expert on the television.

So I decided not to watch any tv buying guide and consider the issue in a user’s location, what is most I needed?. I decided to put together ideas and coordinate them a most harmonious way. Today, I write this tv buying guide, is synthesized from my experience and what I have after buying two first tv.

What room do you want to put the tv in?

Why the TV’s room is most important?

because your room will determine the display technology of the TV screen and the area of the room will determine the size of the TV screen

for example, a television in the living room will have screen size bigger, powerful sound system than in the kitchen and bedroom, this affects my budget to buy a tv. Next is displayed technology, Plasma, LCD or LED technology. Then consider other factors such as resolution, mirror or matte screen, power saving, 3D or Internet connection and more …

So, when you want to buy a new TV, you have to make sure you want to set up a TV in any room. This is the first thing to consider before buying a new television.

Mirror or matte screen

This is an important factor when choosing an HDTV monitor. If you mainly watch TV in the room a lot of light, the matte screen has limited ability to reflect is a good choice.

In contrast, if you look in the dark room (or less light), the mirror screen will be sharper because of the ability to improve the contrast. Most high-end LCD and LED TVs now use a mirror screen, so choosing a mirror or matte screen is only meaningful for low-end HDTVs.

Ideas to place the tv in the living room, kitchen, bedroom?

Living room

Ideas on the tv set in the living room are rich. If you buy a big TV in the living room would be appropriate to choose.

TV in the living room should be in the style you like best, sometimes it is a symbol of your style with the people around. Depending on budget, you can buy expensive or cheap TVs, that does not matter because you should just buy a tv you want.

If your living room has multiple windows or lots of light bulbs then do not use a mirror screen TV, or Plasma TV, because Plasma TVs will not display good pictures in bright places.

Usually, the bedroom is your private place and I’m sure your bedroom will be darker than the other rooms.

So, the TV in the bedroom can be a little thicker than the living room because no one will judge its design except you and because of the darker space, the choice of plasma TVs is the image performance.

Better yet, Plasma TVs are usually cheaper than LCDs and LEDs if they are the same screen size.

In this section of tv buying guide, we made sure each kitchen TV was built well and is easy to control.  A good kitchen TV must also be compact in size and as lightweight as possible. Most families do not use the kitchen as a dining room. So the tv set in the kitchen should be a tv with a small screen, cheap price, sound system just enough to hear news channels. Viewing options, such as a built-in DVD player, are important for those who are using the TV in an area with poor reception.

For this tv, the outer case design is the most important, because you will easily clean it.


Now to continue next step in the tv buying guide, we to the next step: determining the TV’s screen size.

What tv size should I buy?

The size of the TV is big or small depending on the space of the room, financial capacity (the larger the screen size, the more expensive it is) and the preferences of each person.

The minimum size you should choose is 19 inches for kitchen and 32 inches for the bedroom and 40 inches for the living room or the main television.

If you are planning to replace your old TV, you may find the size is too big because conventional CRT TVs have a maximum size of 36 inches. But in reality, increasing the size of the screen is the most cost-effective factor and can be said to be the best in TV upgrades.

And you should know one of the most common complaints after buying a TV is not finding the right size.

How much space have you for a tv?

Depending on the screen size you defined above, a thinner tv will easily save more area, a tv without additional sound system will be more easily set. The TV new generation tends increasingly thinner design, some only 1 inch thick and the frame around the screen (bezel) is also getting smaller, it has called the “slim tv”.

Will TV be set on the floor or installed on the wall?


if the TV set on the floor or on a table, just use the base stand. if you want a higher vision about the need to mount the TV on the wall, you need to use the device called “TV Wall mount” corresponds to the size of your tv screen size.

What is the best distance from tv size to viewing?

TV buying guide - tv viewing distance part

TV buying guide – TV viewing distance part

According to experts, the best distance from tv size to viewing should not be closer to 1.5 times the size of the television screen and should not be 2.5 times the size of the television.

for example, with a 50-inch TV, you should be watching between 75 and 100 inches (2 to 2.5 meters) of the screen. So in addition to the size of the tv, you also need to consider the area where you and others can watch.

Well, at the first step we need to look at all the issues before buying a tv. Now to continue next step in the tv buying guide, we to the next step: determining the display technology.

What is tv display technology is best: LCD TV vs LED TV vs Plasma TV or LDP TV?

Once you have selected the size of your TV, you can continue to narrow your choices by choosing the display technology. Plasma TV, LCD TV or LED. LED TVs are not other TV technologies but LCD TVs that use LED backlighting. The comparing with LCD TV vs LED TV here: How does LCD and LED TV works?

TV buying guide - LCD TV vs LED TV vs Plasma TV

TV buying guide – LCD TV vs LED TV vs Plasma TV

If you want to buy a smaller 42-inch TV, LCD TV is the only option as mentioned on the plasma screen is not effective for production in the under 42-inch size. So, if you want to buy midrange HDTVs, from 42 inches upwards, you can choose LCD or Plasma TVs.

Another type of display technology is a rear-projection (DLP) projector, large in size that starts at 60 inches or more. However, DLP TVs are less popular because they are bulkier than LCD and Plasma TVs. Moreover, LCD TVs and Plasma TVs now have large sizes similar to DLP TVs.

In this tv buying guide, I will not analyze the differences in specs, but rather focus on the differences between TV technologies that most consumers care about,  below is a basic assessment of each type of TV technology.

Plasma TV manufactured by Panasonic, Samsung and LG are typically 42 to 65 inches in size. Particularly there is a 150 inch model of Panasonic but for most people, the maximum size of the plasma TV is 65 inches.

Plasma TV is still the best black today. LED TVs can sometimes reach the perfect darkness level (turn off the LEDs) but generally, when watching movies, the plasma screen will get better black levels. This relates to the contrast ratio.

Screen size: 42-inches or more.

  • Good black visibility should be suitable for viewing in dark rooms; Better viewing angle than LCD.
  • Cheaper than LCD, LED.

  • Mirror screens can reflect light in a room with plenty of light. Few production companies (mainly products of Panasonic, Samsung, LG).
  • Thicker than LCD, LED
  • Consume more power than LCD

Best for use in dark rooms, especially suitable for those who like to watch movies.

LCD is Liquid Crystal Diode. LCD TV is a television display technology based on a liquid crystal display. LCD TV consumes much less power than plasma displays because they work on the principle of blocking light rather than emitting it. LCD TV are produced for the vast majority of people.

Screen size: few inches to 80 inches

  • Less electricity than Plasma; LCD TVs use matte screens that work well in rooms with plenty of natural light or light; Many product options (all manufacturers have LCD TVs).

  • Lose the ability to view in dark rooms and viewing angles.

This type of TV is a good choice if it is used in a room with a lot of light as it limits the latent potential of the technology (as opposed to plasma TVs).

TV LEDs are the brightest TVs today, followed by LCD TVs. Some LED TVs have a brightness of up to 100 ft-L (foot-lambert). This is a huge number if compared to the screen inside the theaters usually only reach 5 ft-L. Plasma TVs are brighter than CRT TVs but can not get as high brightness as LED TVs and LCDs.

Screen size: 32 inches or more

  • Use less electricity than LCD TVs and Plasma TVs; Screen; Some pieces of quality processing; Multiple selectors selected (all manufacturers have LCD TVs).

  • Price more expensive than LCD TVs.

If you are an avid movie buff, and do not want to buy Plasma TV, LED TV is the best choice.

Screen size: 60-inches or more

  • The big screen

  • Much bulkier than LCD and Plasma TVs; Little sample products.

Optimal choice for those who want to have extra screen TVs, from 60 inches upwards

Which TV technology is the winner?

Do not add points 1, 2 and 3 above to determine which technology is the “winner”.

Simply, each person’s needs are different. Perhaps with you, good screen brightness is the most important factor but for others, black is a priority. TVs that meet both current requirements are very expensive (local black).

It is important to define your needs to see which factors are more important!

For example, if you watch a lot of TV during the day and have multiple windows, choose a LED TV. And if you take a look at it and want a good black product, plasma is the best choice

TV Buying guide - what is the best resolution tv to buy HD, Full HD or 4k Ultra HD

TV Buying guide – what is the best resolution tv to buy HD, Full HD or 4k Ultra HD

If you have a large enough budget, you can choose the next-generation TV as 4k ultra HD, the highest resolution and the most colorful display, which is great for experiencing full HD movies or 3d movies. However, if you only have a limited budget, make sure you only pay for your actual needs, this is a reasonable choice.

So should buy HD HD TVs, HD TVs or 4k HD depends on many factors, but the most popular are the following:

How often do you watch HD, full HD or 4k ultra-HD movies?

Choose HD resolutions

If your needs are moderate and want to save more money, should choose HD TV. Small screen TV with HD resolution will be a perfect choice.
For example, I often watch movies on HBO and StarMovie, with many HD resolutions but only some movies with full HD resolution. So, I decided to buy a full HD TV that would be the best choice.

Choose Full HD resolutions

If you want to watch both HD and Full HD movies, the full HD TV is the best choice.

Compare HD and Full HD screens here: HD TV vs Full HD TV what is the difference?

Most 40-inch or larger HDTVs now have a resolution of 1080p or 1920×1080 pixels, but some smaller LCDs and low-end Plasma TVs can still use 720p (1280 x 720 pixels) resolution. ).

On price, there is a difference of 15 – 20% between the 1080p and 720p HDTV models. In terms of quality, the theoretical 1080p resolution will display the maximum definition of HD content. But in reality, the difference between 720p and 1080p resolution is almost indistinguishable, especially when viewed at a distance of over 3 meters.

Choose 4k ultra HD resolutions

If you want to own a TV with a vibrant screen to enjoy movies with the same quality as cinema screening or 3D movies, the TV with 4K resolution is a great choice. Of course, you need to be sure to pay for this television.

Important note: for choose Full HD vs 4k ultra HD, for televisions with screens under 50 inches, the difference is negligible. If your demand is not so high, a Full HD TV is a good choice. Read more: Full HD TV vs 4K TV really have a difference?

Consider the basic features

Also in the tv Buying Guide, I also mentioned some experience when you use the TV you just bought. After selecting the size and screen technology, you should learn more about the parameters and features to consider before making a purchase decision. HDTV manufacturers now list many parameters, including important parameters, and there are a few things you can ignore.

Buy cheap HDMI cables

When purchasing an HDMI cable, sellers may recommend buying expensive cables. But in fact, the quality of expensive and inexpensive HDMI cables is not much different.

Power Saving

There are two main factors affecting power consumption: screen size and screen technology. The bigger the TV, the more power it uses. 32-inch LCD TVs consume half the power of a 52-inch LCD TV.

Different display technologies also differ in terms of power consumption. On average, Plasma TVs consume 3 times more electricity than LED TVs and more than 2 times LCD TVs when images are in the same brightness mode. Power-saving TVs can save considerable bills for many years.

If you are interested in this, there are many ways to reduce the electricity consumption of the TV. Refer to the article “Power Saving Tips for Television“.

3D support

Among the flat-screen TVs, 3D content capabilities only appear in the high-end models of major manufacturers launched in 2010 back here, so their prices are very expensive.

In addition to the need for 3D glasses, 3D content and 3D sources can increase costs for 3D TV users. If you are really interested in 3D TV, check out the limitations of this TV.

Equipment against voltage increase

You should protect your HDTV by providing a stable power supply through the use of an anti-voltage device. This is a device used to automatically turn off the circuit when sudden power abruptly can burn up the TV.
