TV Buying Guide 2018. All you need to know before buying a TV. Screen Size Nowadays the amount of screen sizes available is outstanding, from 14 inches to over 100 inches. So how do you figure out the right size for you? According to THX, you should divide the diagonal width, by 0.84 inches. This will give the result of the ideal distance between you and the screen.

Another calculation you could try is a seating position, between 1 and a half or 2 times the diagonal width of your screen. Using this approach, a 65-inch screen would work for a viewing distance between 8.1 and 10.8 feet.
Wall Mounting If you one of those who think this will work for you, there are a few things to consider. First, remember that the TV will be right up flat to the wall, so you might want to go up a screen size or two. Second, many TVs don’t ship with wall mounts included. So look for a TV with wall mount screw positions compatible with the VéSA industry standard.
Pannel Technology There are two types of TV technology, LCD and OLED. And both are important variations on the LCD industry. LCD/LED TVs, use panels of liquid crystal pixels illuminated by external light sources.
The advantage of LCD TVs are the brightness, the affordability and durability. Their main disadvantages are limited viewing angles, and difficulties controlling light in the picture.
There are two types of LCD panel: IPS and VA. IPS are predominantly made by LG Displays. Feature in LG LCD TVs, and also in some usually affordable models from other brands. VA panels are more widely used, and are made by a variety of manufacturers.
I P S panels offers slightly wider viewing angles than VA panels, but struggle with contrast. On the other hand V A panels feature narrower viewing angles. But generally produce much better contrast.

OLED OLED TVs use a system of organic phosphors, that enable each pixel to generate its own light. This allows a superior contrast and light precision than you can get with even the most advanced LCD TV. OLED TVs can be watched from much wider viewing angles than LCD TVs, without colour or contrast reducing.
Backlight Technology If you want to buy an LCD TV, the key point to consider is how the panel is lit. Because this has a great impact on the screen contrast.
Some panels use lights mounted on the edge of the screen, edge lit panels, while others use lights mounted directly behind the screen.
Generally speaking, TVs with lights behind the screen deliver better contrast than edge-lit models. But these models don’t generally feature such slim designs, tend to cost more, and often consumes more power. Other option to consider with LCD TVs is local dimming. This can dramatically improve contrast.
Connectivity These days main connections are: HDMI, USB ports and multimedia support. With HDMI try to get at least three. And With 4K TVs, try to get a TV with the 2.0 rather than 1.4 HDMI version.
USB ports are useful for both playing back multimedia. Look for at least two, ideally three. But keep an eye on the USB-C type, it will be a stander soon. Most TVs have built-in wi-fi and Ethernet ports, so that you can connect them to the internet.
Curved or Flat TV? Curved TVs are much less common in 20 17. If you are looking to buy a very large TV, or you’re going to be sitting pretty close to your screen, a curved screen can make a slightly more immersive experience.
Curved screens follow the shape of your eye making the corners of the picture look sharper than they do on a flat TV. And also curved screens loose less colour and contrast when viewed from an angle.
However, there are issues. First, they tend to distort any onscreen reflections, Second, if you watch from an angle of really much more than 20 to 25 degrees, the picture can start to look shortened. And finally, if you’re not seat in the optimal position (if you’re either too far back or off to the side), curved TVs can distort the picture’s geometry.
HDR High dynamic range. HDR TVs are able to produce pictures that contain much more brightness and contrast than normal TVs, as long what you watching contains HDR luminance data. All current HDR TVs also support wider colour spectrums (often described as wide colour gamut, or WCG.
Currently there are three types of HDR. HDR10 is the industry standard. And all TVs support it. Dolby Vision, adds an extra layer of information, that tells a TV how to render pictures on a scene. Only some brands like LG, Vizio, TCL and Sony support this.
And there is also Hybrid Log Gamma, that was designed for HDR broadcasts.

QLED – Quantum Dots Some LCD TVs, usually high end TVs, have started to use this technology. Quantum Dot technology delivers wider colour ranges than you can get with normal LCD panels.
Quantum Dots are tiny particles, from 2 to 10 nanometers in size, with each size capable of emitting a different colour, avoiding colour filters and white LED Backlights, two things that typically limit an LCD TV colour performance.
QLED TVs are generally markedly more expensive than normal LCD TVs, and Samsung is still a biggest reliable manufacture in this Quantum Dot technology, with its 20 17 models.
But there are alternatives to Quantum Dots when comes to expanding colour range. Triluminos models from Sony, use wide-range phosphors, and LG with Nano Cells in its high end TVs.
Brigtness Screen brightness. As measured in nits, and with many HDR proponents including Dolby Vision, we are enter on a ‘nit race’ where TVs will push to get brighter and brighter.
The brightest LCD TVs (Samsung’s upcoming ‘QLED’ models) can get as bright as 2000 nits. The generation of OLED TVs, are reckonized to get to between 800 and 1000 nits.
Contrast Contrast Ratio is basically a calculation of the difference between a screen deepest black and brightest whites, written for instance as, 10,000 to 1.
Speakers The sound quality of a flat TV can vary greatly. This is something that you should pay attention if you do not intend to use an external sound system. Look how many speakers a TV has, and its configuration.
For instance, a 2 to 1 configuration would indicate 2 stereo main speakers with 1 dedicated bass speaker. Or a 3 to 1 configuration, that would point to a dedicated centre or dialogue channel, alongside stereo and bass speakers.
Subwoofer speakers for Bass are always welcome, because is known how much TV speakers suffers from lack of lower end sounds. Another audio issue is lack of space available to speakers in thin TVs. Meaning, they usually have to expel their sound downwards. TVs that manage to provide forward sound results in a much cleaner and more powerful sound.
Another warning is TVs that offers DTS, or Dolby Digital surround decoding. No TV can deliver anything close to a proper surround sound from its own speakers. The best solution here is to use actual rear speakers, especially with a subwoofer to add bass.
Smart TV Today Almost every TV can connect to a network, enabling the use of online features, or to access media files stored on other devices such as Cell-phones, tablets, Network Attach Storage etc..
But in reality, the quality of such ‘smart’ features can vary greatly. Don’t be seduced by app quantity. The vast majority of TV apps are pointless, App quality is much more important. In fact, for many the only online feature that really matter, are the online streaming services. Especially Amazon Prime, Netflix, and catch-up services for your region’s broadcasters.
Finally, the simplicity of a smart TV interface will rule in how much you might use it. Currently, LG’s web OS and Panasonic’s Home Screen systems handle their content most effectively.
