We are always asked ‘which is the best TV?’ That is a bit of a loaded question as there is no perfect TV for every home, every person, every situation. It’s like a computer – different things appeal to different users. But there are a few good guidelines to use for picking a TV that you will be happy with for years to come. Stick to the major brands. This is especially true if you are going to using a sound system, a universal remote or other third party devices. The major brands play nicely and have standard protocols that many of the budget brands lack. We recommend only Sony, Samsung and LG TVs for this reason Don’t worry about the speakers. The speakers on all modern TVs sound awful. In order to make the TV so thin, the speakers have been shrunken down and they are really an afterthought. Assume you will use either a 5.1 surround system or a sound bar Don’t worry about the Smart TV interface. None of the TVs implement it will. We recommend using a dedicated streaming device: Apple TV, Roku or Amazon Fire. The TV should provide the best picture possible and that is what you should base your decision on. It is a display device, use other, dedicated devices for content (streaming box, blu-ray player, cable box, game system, etc) Get the right size. A good method is to convert your viewing distance (from your eyes to the screen) to inches. THX recommends a screen diagonal that is 0.84x your seating distance, but that leads to some very large screens, like an 85” screen for a 12’ viewing distance. Instead we recommend clients divide the seating distance (in inches) in half and that is roughly the right size TV for your room. Don’t forget to take into account if you will also watch the TV from farther away – maybe from an open kitchen or a dining area behind the living room and go up a bit in size if that is the case. There are plenty of on-line calculators to use for calculating TV size. Edge-lit vs full back lit. With LED TVs, the screen is actually lit by a backlight and panel turns pixels on and off to allow that light to pass through or not. A few years ago when TVs became ultra-thin, the concept of an edge-lit backlight was introduced. This is much like it sounds – the light source is around the edge of the screen and is designed in such a way that it reflects off of materials behind the screen to light up the pixels. This can produce hotspots and also does not allow the backlight to be precisely turned on and off to lit up sections of the screen. With a full back light, the darks are darker and more inky, providing a better picture and better color. Many manufacturers have been able to reduce the size of the full back-light array so TVs with a full back light are only an inch or so deeper than TVs with edge light technology. OLED vs LED/LCD. OLED is the latest in screen technology and provides and amazing vibrant and realistic color palette with deep, rich blacks. The drawback is that is currently quite expensive, although prices are coming down and have dropped significantly in the past two years. LED/LCD is the technology that has been in use for the past several years. LCD is the Liquid Crystal Display that creates the image. LED is the backlight technology, which lights up the LCD screen. HDR. While most TV shoppers are focused on 4K resolution (2160p vs the prior standard of 1080p). There are basically twice as many pixels, so each one is smaller, making the picture sharper, although the human typically can not see the difference on popular screen sizes at a normal seating distance. What is important to look for, however, is HDR (high dynamic range). HDR expands the color gamut that a TV can reproduce, resulting in deeper, richer, more realistic colors. This, in turn, creates more detail on the screen. While there is not much content yet for 4K or HDR, there will be an that is something you should look for in your screen. NITS. While HDR does require much more information to recreate the wider color gamut, it also requires a much higher light output to do so accurately and well. Similar to the Lumens specification we have seen on projectors for years, NITS may become a more common spec we see in TV marketing. Basically a nit is a measure of light output by the TV screen. LED/LCD TVs capable of HDR should display at least 1,000 nits, while for an OLED screen, around 550 nits is the optimal. The reason for the disparity is that we are talking about High Dynamic RANGE. The key is that the TV is able to display the difference between a very bright part of the screen (say the sun shining) and a very dark part of the screen (deep shadows) on the same scene, with high accuracy Honestly, other than the aesthetics of the TV – for example the color and thickness of the bezel around the screen, the thickness of the TV, etc, it really comes down to the size, OLED vs LED and NITS. You really can’t go wrong with what is available today as long as you stick to the major brands
