The following section lists the main terms you will encounter in the description of any current TV. Some are known to everyone, others are more niche – we will try, in any case, to describe them in accessible words, easy to understand by any of our readers:
Refers to the distance between any two opposite corners of a TV screen. Nowadays, you can rarely find models whose housing diagonal far exceeds that of the screen, therefore you can orient yourself according to this size and to figure out where the chosen device will fit best.
Represents the total number of pixels on the screen. The pixel is the individual unit of color generation, and there can be millions of them on a display. In product descriptions, the resolution is presented as the product of the number of pixels in length x the number in pixels, not their total sum.
For example, for an HD Ready screen, 1366 x 768 pixels will be displayed as a resolution and not 1,049,088 pixels. Thus, you also have an idea about the ratio between the two dimensions of the display.
You can find plasma screens, LED, AMOLED, or OLED, or more recently, QLED or super AMOLED. The respective terms refer to the technology through which the pixels work, each of them resulting in more or less natural or more pleasant and relaxing colors for the eyes. QLED and super AMOLED are the most advanced and expensive at the moment.
Length x width ratio
Represents how big one side of the screen is relative to the other. The old TVs were on the 4: 3 ratio, meaning the width was three quarters of the length. The new standard for most modern monitors and TVs is 16: 9, which means a more pronounced difference between the two dimensions, compared to 4: 3. Occasionally, but rarely, you can also find 16:10 displays.
