The optimal viewing distance when watching a 55 inch TV is 1.69 m (5.5 ft). The most immersive viewing experience is achieved when 40 degrees of your field of view is taken up by the screen.

You can measure the dimension of a 55 inch TV (138cm) by calculating the diagonal length, from the upper left-hand corner to the lower right-hand corner.

HDR (High Dynamic Range) technology adjusts the light levels to produce images with greater levels of contrast and a wider color gamut compared to standard TVs, resulting in more realistic-looking images. HDR-supporting TVs are also excellent for gamers who need to locate targets in darker areas of the screen, as HDR can create high contrast between light and dark areas.

Resolution is a term that describes the density at which these minuscule dots, known as pixels, are arranged on the display. These individual pixels come together to form the image that is visible on the screen. As a result, a greater pixel count directly correlates with a higher resolution, yielding a clearer and more detailed picture. 55 inch TVs are offered in both 4K and 8K resolutions. The 4K version features a resolution of 3840 x 2160 pixels, providing a high level of detail and clarity in the image. The 8K version provides even greater detail and clarity, with a resolution of 7680 x 4320 pixels, which is four times the number of pixels found in a 4K TV. With this ultra-high resolution, it becomes possible to display incredibly sharp and detailed images.

The 55 inch QN90 Neo QLED TV is the optimal choice for gaming, with its support for 4K resolution and Game Mode. It provides an immersive gaming experience with features like Motion Xcelerator Turbo Pro at a smooth 144Hz refresh rate, Low Input Lag, FreeSync Premium Pro and 4 HDMI 2.1 ports for seamless connectivity.

When installing your TV, you have the choice between using a stand or a wall mount. If you opt for a stand, it's important to consider its design and dimensions, as well as where you plan to place your TV. On the other hand, if you decide to go with a wall mount, make sure to take into account your TV's size, weight, and viewing angles. A wall mount allows the TV to be positioned flush against the wall, giving your space a sleek and polished appearance.
