| Size class
Size class of the display as declared by the manufacturer. Often this is the rounded value of the actual size of the diagonal in inches. |
27 in (inches) |
| Diagonal
Approximate diagonal size of the display. If the manufacturer does not provide such information, the diagonal is calculated from the width and height of the screen. |
685.8 mm (millimeters) 68.58 cm (centimeters) 27 in (inches) 2.25 ft (feet) |

| Panel type
There are various panel technologies. Each has its own specific features – viewing angles, color reproduction, response time, brightness/contrast, production cost, etc. The image quality depends directly on the type of the display panel used. |
IPS |
| Panel bit depth
The most widely used panels are those with 6, 8, and 10 bits for each of the RGB components of the pixel. They provide 18-, 24-, and 30-bit color, respectively. |
10 bits (8 bits + FRC) |
| FRC
Frame Rate Control (FRC) is a method, which allows the pixels to show more color tones. With quick cyclic switching between different color tones, an illusion for a new intermediate color tone is created. For example, by using FRC, a 6-bit display panel is able to show 16.7 millioin colors, which are typical for 8-bit display panels, and not the standard 262200 colors, instead. There are different FRC algorithms. |
Yes |
| Colors
The maximum number of colors, which the display is able to reproduce, depends on the type of the panel in use and color enhancing technologies like FRC. |
1073741824 colors 30 bits |
| Aspect ratio

| Pixel pitch
The pixel pitch shows the distance from the centers of two neighboring pixels. In displays, which have a native resolution (the TFT ones, for example), the pixel pitch depends on the resolution and the size of the screen. |

50000000 : 1 |
| HDR
HDR expands the contrast ratio (peak luminance and minimal black levels) and color palette to achieve more details across the whole image – from the darkest parts to the brightest ones, which results in more realistic and life-like image. |
