Buying a TV

Buying a TV can be overwhelming, with the need to make a number of choices such as size, features, and available inputs or ports. But with this guide, you are that much closer to getting the perfect TV to compliment your current home or office setup.
5 things to keep in mind
screen size
In most cases, size is the biggest factor when selecting a TV. To select a screen size, you might want to consider the number of people that would watch the TV at a given time, where you are going to place the TV, and then pick the largest screen size that will fill the available space without going over budget. The most popular TV size today, considering price, performance and the space available in the typical living room, is between 50 and 65 inches.
calculating the best size of tv for your room
Consider the room in which the TV will sit. Measure the distance (in inches) between where you plan to mount the TV and where you plan to sit. To calculate the best size TV for your room, measure your viewing distance (in feet) and multiply that by 7.7. So if you have a 42-inch TV, you can sit 84 inches (7 feet) away for a comfortable and immersive experience. If you're looking at a 4K ultra-high-definition television, the formula changes a bit. Because of the increased resolution, the recommended viewing distance is between 1 and 1.5 times the screen size. So if you buy a 50-inch TV, it would need to be placed between 50 to 75 inches away from where you'd sit.

screen resolution
The resolution of a television is the number of pixels in each dimension the TV can display natively. A pixel is essentially a lit-up square that produces a specific color. The more pixels you have on a TV, the more detailed the picture on the screen will appear. The sharpness of the TV here is usually in terms of horizontal lines of pixels.

Ultra HD (or 4K as it is more popularly known) looks great, and it is becoming more popular. Several streaming services like Netflix, Amazon Video and even YouTube have started offering 4K content, and untra HD Blu-ray discs are becoming readily available. Full HD or 1080p is still the most common screen resolution today, but 4K is increasingly becoming the standard, and the better choice if you want something future proof.

picture quality
Picture quality has remained an important part of the TV equation. OLED, QLED, LED and LCD are competing technologies that each offer a trade-off between price and picture quality. However, their basic capabilities are identical.
QLED: The Q in QLED stands for quantum as in quantum dot LED TVs. This technology uses quantum dots (QD), semiconductor nanocrystals which can produce pure monochromatic red, green and blue light. QLED TVs have a rich colour volume and higher light output and a better colour for HDR sources. Most importantly, low power consumption makes QLED more than twice as power efficient as OLED at the same colour point.
OLED: An organic light-emitting diode (OLED) is a light-emitting diode (LED) in which the emissive electroluminescent layer is a film of organic compound that emits light in response to an electric current. OLEDs have large fields of view and do not require backlighting like LCDs. They can be so small that they can be used as individual pixels, millions of which occupy your TV screen, lighting up and shutting off totally independent. Because of this flexibility, when an OLED pixel is shut off, it is completely off, which leads to a deeper and more natural shade of black.
LED: A light-emitting diode (LED) is a two-lead semiconductor light source. It is a p-n junction diode that emits light when activated. When a suitable current is applied to the leads, electrons are able to recombine with electron holes within the device, releasing energy in the form of photons. LED TVs produce more vivid images compared to fluorescent light. LED TVs have the ability to create dark areas in the screen and control it, which is something that's missing in traditional LCD TVs. Both edge lighting and full-array backlighting have the capability to adjust black levels, allowing for dark blacks and significantly better dark scenes. Moreovr, accuracy in backlghting for colored pictures is also better with LED TVs.
LCD: A liquid-crystal display (LCD) is a flat-panel display or other electronically modulated optical device that uses the light-modulating properties of liquid crystals. Image is perfectly sharp at the native resolution of the panel. The high peak intensity produces very bright images but has limited viewing angles.
Smart TVs: A smart TV is a television set with integrated internet and interactive web features. They have built-in Wi-Fi for connecting to Internet-based services like Netflix for streaming videos, downloading on-demand movies, playing games or even posting to Facebook. The recent models can even search for content across streaming services and live programming on cable and satellite.

TV Shape Curved VS Flat Screen
curved tv
Curved TVs are sleek and offer a greater level of immersion to the viewers sitting in front of them by slightly expanding the perceptible quantity of screen space for their diagonal size, while Flat Screen TVs are far more amenable to be hanged along any vertical space.

HDMI Port: HDMI (High Definition Multimedia Interface) serves as an efficient method to transfer video and audio data to HDMI-ready TVs, from streaming media players, Blu-ray players, game consoles and more. HDMI carries both the picture and sound over one convenient cable, unlike traditional A/V ports, which require at least two separate cables
USB Port: TVs with USB ports allow you plug in a hard drive, flash drive, or other USB storage device to view media files on your television set. These include photos, music and of course video files.
