A Quick Guide to 55-Inch Television Sets

If you are in the market for a 55-inch television, then you may have many decisions to make. A television set comes with different features and specs, leading to many possible configurations. However, eBay is a convenient source for all your shopping decisions.

How do you choose the right TV set?

Here are the most important factors you should consider:

  • Resolution - For a 55-inch set, the most common resolutions tend to be 1080p and 2160p, also known as 4K, with some 720p sets available as well. Whereas a 1080p set has approximately two million pixels, a 2160p set has around eight million pixels, allowing it to display more detail at once. However, a 2160p set is also more expensive.
  • Refresh Rate - A television with a higher refresh rate can update the image more times every second. This can help minimise motion blurring and create smoother video.
  • Response Time - Response time measures the time it takes in milliseconds for each pixel to transition between different colours or shades of grey. A lower response time reduces lagging and certain annoying visual effects.
  • Smart TV Functionality - A smart TV integrates internet functions such as web browsing and online streaming directly into the television set. This makes it easier to experience online media directly from your living room.
What are the main types of TV sets?

LCD TVs are the most common type of display on the market, but OLED TVs also occupy an important place. Here is what you need to know about them:

  • LCDs - LCD stands for liquid crystal display. In a typical LCD panel, the liquid crystals can be manipulated to form an image on the screen, but they do not emit light directly. Instead, an LED backlight illuminates the image, making it appear much brighter and more vivid. For this reason, an LCD panel is sometimes called an LED-backlit LCD TV or just an LED TV.
  • OLEDs - OLED stands for organic light-emitting diode. It is similar to LED technology, except it has a layer of organic compounds placed between two electrodes. Whereas an LCD TV needs a backlight, the OLED TV creates its own light. For this reason, the OLED set can deliver deeper blacks because each pixel can be individually turned on or off. The display also tends to be quite thin and lightweight.
What is HDR?

HDR stands for high dynamic range. It is a measure of brightness level, colour range, and contrast ratio, meaning the difference between dark and light colours. Essentially, an HDR set is brighter and more colourful across a wider range, and it displays more details within that range. You will need both a television set that supports HDR and video content with HDR encoded in to take advantage of this feature.
