Explanation about television specifications
1. Resolution: HD Ready, Full HD, and 4K (Ultra HD)
The resolution indicates the maximum amount of pixels that fit on the screen and determines the sharpness of images on your television. The most common resolutions are, in ascending order, HD Ready (720p, 1280 x 720 pixels), Full HD (1080p, 1920 x 1080 pixels), and 4K or Ultra HD (2160p, 3840 x 2160 pixels). The more pixels, the sharper the image. This allows you to see even the smallest details, like letters, much clearer. When choosing a television, consider both the resolution and size of the screen, relative to distance between you and the TV. An HD Ready resolution will only look good on smaller televisions (<32 inches). Full HD will look good on any screen size, as long as you keep to our recommended viewing distances. a 4K TV (Ultra HD) is recommended if you like to sit close to a large television.
2. Smart TV
You can connect a smart TV to the internet via WiFi or a cable, which enables access to apps like Netflix, Spotify, and Youtube. You can also view missed broadcasts or the weather report. With help of the integrated browser you can easily surf the web. A smart TV also includes a built-in media player that lets you stream movies and series via the internet, a computer, or a NAS in your home network. You can easily play files stored on a USB drive via the USB port.
3. Refresh rate (Hertz)
The refresh rate indicates how often your television can reconstruct an image. This number is expressed in Hertz (Hz). A 50Hz television can reconstruct an image 50 times per second, while a 100Hz television can do this a 100 times per second. You can best see the difference in moving images, like a sports match. A TV with a low refresh rate doesn't have enough time to reconstruct images in images and 'misses' information. This can be seen from the jerky depiction of movement. A television with a higher Hertz value (100Hz or 200Hz) also smoothly displays fast-moving images.. The 'real' refresh rate of a television is always 50, 100, or 200Hz. Certain manufacturers advertise higher Herz values, like Panasonic's BMR or Samsung's Clear Motion Rate. These values always contain techniques that improve the image with help of post-processing.
4. LED (LCD), OLED and Plasma
These are names for the type of screen that is in your television. LED (LCD) is by far the most popular. It is an LCD screen with LED lighting. The image quality is great for the average living room, the screens are thin and the energy consumption is relatively low.
OLED is the newest and best image technology you can get at this moment. The pixels of an OLED screen light themselves, so no backlight is needed. The result is an image with perfect black levels and true-to-life, rich colors.
Plasma televisions are praised for the same reasons as OLED TVs, but the energy consumption is high and the maximum image resolution is low. For that reason no plasma TVs are made anymore.
5. HDR (High Dynamic Range)
A High Dynamic Range (HDR) television displays a larger spectrum of light and shows differences between light and dark more accurately than a 'normal' television. That's why an HDR screen has a larger color volume: you see more colors and small color differences are accurately displayed. As a result, an HDR screen is able to show more true-to-source images than a regular screen. Both bright and dark scenes contain more detail because an HDR TV has better lighting and shading control. To take advantage of an HDR screen, you'll need special HDR videos. Netflix already offers a small selection of such videos. Good to know: in order to display HDR images from a 4K (UHD) Blu-ray player, your television must possess an HDMI 2.0a port. Streaming HDR images via services such as Netflix is always possible on an HDR TV.
A 3D television provides you with depth in movies and series. Put on your 3D glasses and it'll feel like the images are really moving. There are 2 types of 3D television: active and passive. An active 3D TV always uses 3D glasses that alternately block the image in 1 eye at a rapid pace. Because of this, each eye is shown a different image. This allows for a high image quality, but the flickering effect can be experienced as bothersome. With passive glasses, one eye is shown the even lines in the image, while the other eye only sees the uneven lines. This technique is easier on the eyes, but at a decreased image quality because the resolution is halved. You can compensate for this effect by choosing for a television with a higher resolution, like a 4K TV.
