Are you looking to buy a new TV in this video everything you need to know before buying a new television 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 x 0.
8 4 inches this will give the result of the ideal distance between you and the screen using this method if you get a 65-inch TV you should sit around 6.
5 feet from it another calculation you could try as a seating position between one and a half or two times the diagonal width of your screen using this approach a 65 inch screen would work for a viewing distance between 8.
1 and ten point eight feet but if you want you can try the viewing distance calculator you find the links in this video description below 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 mounts crew positions compatible with the vesa industry standard and another thing to keep in mind is the viewing angles especially vertical viewing angles if you are planning to mount your TV near feeling or above a fireplace something typically not recommended 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 display's feature and LG LCD TVs and also in some usually affordable models from other brands VA panels are more widely used and made by a variety of manufacturers IPS panels offers slightly wider viewing angles than VA panels but struggle with contrast on the other hand VA panel feature narrower viewing angles but generally produce much better contrast OLED TVs use a system of organic foss foss that enable each pixel to generate its own light this allows a superior contrast and like precision than you can get with even the most advanced LCD TV olaide TVs can be watched from much wider viewing angles than LCD TVs without color or contrast reducing however there are also issues with an OLED TVs they're still substantially more expensive and old lade TVs currently can't get nearly bright like a LCD TV something that could become an issue with HDR content 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 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 the 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 I dearly three but keep an eye on the USBC 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 curb TVs are much less common in 2017 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 curb screams follow the shape of your eye making the corners of the picture look sharper than they do on a flat TV and also curved screen loose less color and contrast when viewed from an angle however there are issues first they tend to distort any on-screen 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 are not feet in the optimal position if you're either too far back or off to the side curved TVs can distort the pictures geometry 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 luminant data all current HDR TVs also support wider color spectrums often described as wide color gamut all wcg currently there are three types of HDR HDR 10 is the industry standard and all he be supported dole division adds an extra layer of information that tells a TV how to render pictures are themed only some brand like LG Vizio TCL and sony support this and there is also hybrid log gamma that was designed for HDR broadcasts some LCD TVs usually high-end TVs have started to use this technology Quantum Dot technology delivers wider Quantum Dot technology delivers wider color ranges than you can get with normal LCD panels quantum dots of tiny particles from two to ten dena meters in size with each size capable of emitting a different color avoiding color filters and white LED backlights two things that typically limit an LCD TV color performance, quantum dot TVs are generally markedly more expensive than normal LCD TVs and samsung is still a biggest reliable man you actor in this quantum dot technology with its 2017 models but there are alternatives to quantum dots when comes to expanding cover range triluminos models from Sony use wide range fossils and LG with nano selves in its high-end TVs screen brightness as measured in NITS, and with many HDR proponents including Dolby vision we are enter on an it race where TVs all push to get brighter and brighter the brightest LCD TVs samsung's upcoming q LED models can get as bright of 2, 000 nits the 2017 generation of OLED TVs are recognized to get to between 800 and 1, 000 nits contrast ratio is basically a calculation of the difference between a screen deepest black and brightest wives written for instance as 10, 000 to 1 but now few TV brands are quoting contrast ratios the sound quality of the 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 two to one configuration would indicate two stereo main speakers with one dedicated bass speaker or a three to one configuration that would point to a dedicated center or dialogue channel alongside stereo and bass speakers sub woofer speakers for bass are always welcome because is known how much TV speaker suffers from lack of lower end sounds another audio issue is lack of space available to speakers and 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 of Stevie's 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 sub woofer to add bass today almost every day we 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 attached 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 regions broadcasters finally the simplicity of a smart TV interface will rule and how much you might use it currently LG's webOS and Panasonic's home screen systems handle their content most effectively I'd like to thank you for watching and if this video was useful to you subscribe to this channel that I'm sure you already did and I'll see you in the next video care.
