Find Your Perfect TV: A Comprehensive Buyers Guide

In today’s world, TVs are not just a source of entertainment but an integral part of our homes. With so many different types of TVs available in the market, it can be difficult to decide which one to buy. This guide will help you understand the different types of TVs, their features, and what to look for when buying the perfect TV for your home.

Types of TVs

  • OLED TV: Unlike LED TVs, OLED TVs don’t use a backlight. Instead, each pixel in an OLED TV can be turned on or off individually, improving the contrast ratio and providing deeper blacks. However, individual pixels can degrade over time leading to “permanent image retention.”
  • LED TV: LED TVs are a good option for bright rooms as they are bright enough to combat natural light. However, different types of LED backlighting can cause light to “bleed” from the brightest parts of an image to the darker areas.
  • Full-Array Local Dimming: Full-array LED TVs have a feature called “local dimming,” which divides the LED backlights into “zones.” This improves the overall contrast and provides deeper blacks; the more zones a TV has, the deeper the blacks will be.

HDR: High Dynamic Range

  • HDR (high dynamic range) enhances the details in the shadows and highlights of an image, providing whiter whites, deeper blacks, and a wider range of colors compared to Standard Dynamic Range (SDR).
  • HDR10 vs HDR10+ vs Dolby Vision: HDR10 is the most popular standard but can make an entire movie look brighter or darker than it should be. HDR10+ and Dolby Vision, on the other hand, provide brighter images, support more colors, and produce a more natural image.

Refresh Rate

  • Refresh Rate: A TV’s refresh rate refers to how many images a screen can display per second. A higher refresh rate provides smoother motion, especially when watching sports or playing games on current-gen consoles. Currently, the minimum refresh rate to look for is 120Hz.

Ports and Connectivity

  • Ports: When buying a TV, it is important to make sure it has the right ports. You want a TV with several HDMI 2.0 or HDMI 2.1 ports. HDMI 2.0 is the most common standard but if you have a latest-gen gaming console, make sure to buy a TV with at least one HDMI 2.1 port.
  • Ethernet Port: If you have a smart TV, you want to buy a TV with an Ethernet port to connect directly to your router for the most reliable signal.

Should You Buy a Smart TV?

  • Smart TV: A smart TV connects to the internet and allows you to watch movies and TV shows on streaming services, connect to your smart speakers, and control the TV using voice commands. Each smart TV comes with a built-in streaming platform and a dedicated smartphone app. Some smart TV apps even let you connect wireless headphones or stream content from your smartphone to the TV.

When buying a TV, it is important to consider your needs and budget. This guide provides a comprehensive overview of the different types of TVs, their features, and what to look for when making your purchase. With the right TV, you can enjoy a truly immersive viewing experience.
