Explanation about television specifications
Resolution: HD Ready, Full HD, 4K, and 8K
Resolution determines how many pixels fit on your screen. A higher amount of pixels results in a sharper image, so small details like letters will be more clearly visible. When choosing the resolution, take the viewing distance and screen size into account. HD Ready resolution only comes to life on smaller televisions (< 32 inches).. If you want to sit close to a large television, we recommend a 4K TV.
In ascending order of sharpness, the resolutions are:
- HD Ready - 720p, or 1280x720 pixels
- Full HD - 1080p, 1920x1080 pixels
- 4K (UHD) - 2160p, or 3840x2160 pixels
- 8K (UHD) - 4320p, or 7680×4320 pixels
You can connect a smart TV to the Internet via WiFi or a cable. This gives you access to apps like Netflix, Spotify, and YouTube. As a result, you can easily watch missed broadcasts, the news, or the weather forecast. Most smart TVs have an app that lets you stream from your smartphone or tablet to the screen. You'll be able to quickly and easily show your vacation photos. Some TVs also have an integrated speech assistant. Via simple voice commands, you can search for a video, adjust a function, or check the weather. Each smart platform offers different apps and features.
Refresh rate (Hertz)
Each video consists of a number of images, known as frames. The refresh rate of a television indicates how many frames a screen can display per second. The unit of frequency is expressed in Hz (Hertz). A 50Hz television can refresh the screen up to 50 times per second, while a 100Hz television can do this 100 times per second. The difference mainly becomes apparent with fast-moving images, like a sports game. A 100Hz TV displays images like these smoothly. The 'actual' refresh rate of a TV is always 50Hz or 100Hz. Some manufacturers offer a higher Hertz value, like Panasonic does with BMR or Samsung with Clear Motion Rate. These higher values have integrated techniques that enhance the image afterwards.
LED (LCD), QLED, OLED, and Plasma
These are the names of the type of screen that could be in your television. An LED TV has an LCD screen with LED lighting. Samsung QLED TVs have a layer of Quantum dots that convert light into colors. As a result, these TVs provide a realistic color gamut so that even the slightest nuances become clearly visible.
The pixels an OLED screen light up, so you don't need background lighting. This results in an image with perfect black levels and realistic and vibrant colors. Because OLED TVs don’t require a backlight, the screens are much thinner as well.
Plasma televisions are praised for the same reasons as OLED TVs, but they have a high energy consumption and a low image resolution. For this reason, plasma TVs are no longer being produced.
HDR (High Dynamic Range)
A High Dynamic Range (HDR) television covers a wider spectrum of light and shows the difference between light and dark more accurately than a 'regular' SDR television. As a result, an HDR screen has a larger color volume. Not only will you see more colors, but the color differences will be displayed clearly as well. An HD screen shows more of the original footage than a standard screen. In a brightly lit or dark setting, you'll see more details because an HDR TV displays more shades of light and dark. Another advantage is the fact that an HDR screen can show dark and light areas in 1 image without loss of detail.
Behind the screen of a LED-LCD TV, you can find light bulbs that emit light through the pixels. In turn, these pixels generate colors and a clear image. The downside is that the backlight also illuminates the darker parts of an image,so black images aren't entirely black. TVs with local dimming have a backlight that consists of dozens to hundreds of light bulbs, which are divided into zones. Because the TV can dim and brighten each individual zone, you'll get more realistic black levels and a strong contrast between dark and light images. OLED TVs don't have a backlight, they have 'self-emitting' pixels instead, which can light up individually or become dark completely. This impressive feature results in perfect black levels and a striking contrast.
The viewing angle of a TV determines at which point the image quality starts to decrease when you're watching from the side. If you're sitting too far to the left or right, you'll be bothered by reflections, the colors will become distorted, or the image will become darker. That's why a wide viewing angle is important if you often watch TV with a large group of people. The viewing angle mostly depends on the screen type. While OLED screens are known for their wide viewing angle up to 85 degrees, VA screens usually have a small viewing angle of about 20 degrees. On top of that, manufacturers apply various techniques to improve the viewing angle.
