ProArt
Model

Designation of the model.

PQ22UC

Display

Information about the main characteristics of the display - panel, backlight, resolution, refresh rate, etc.

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.

21.5 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.

546.1 mm (millimeters)
54.61 cm (centimeters)
21.5 in (inches)
1.7917 ft (feet)
Width

Approximate width of the display. If the manufacturer does not provide such information, the width is calculated from the diagonal and the aspect ratio.

478.08 mm (millimeters)
47.808 cm (centimeters)
18.822 in (inches)
1.5685 ft (feet)
Height

Approximate height of the display. If the manufacturer does not provide such information, the height is calculated from the diagonal and the aspect ratio.

268.92 mm (millimeters)
26.892 cm (centimeters)
10.5874 in (inches)
0.8823 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.

OLED
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
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.

No
LUT

A LUT (Look Up Table) contains precalculated sets of values that are used to apply transformations to the input color data so that the resulting data meets certain (the desired) visual standard and color accuracy. For example, LUT can be used to emulate/map different color spaces and gamma settings. Many professional monitors as well as some TVs have programmable internal LUTs allowing more control over the image.

14 bits
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

The ratio between the horizontal and the vertical side of the display. Some of the standard and widely used aspect ratios are 4:3, 5:4, 16:9 and 16:10.

1.778:1
16:9
Resolution

Information about the number of pixels on the horizontal and vertical side of the screen. A higher resolution allows the display of a more detailed and of higher quality image.

3840 x 2160 pixels
Ultra HD (UHD) / 4K / 2160p
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.

0.125 mm (millimeters)
0.0125 cm (centimeters)
0.0049 in (inches)
0.0004 ft (feet)
Pixel density

204 ppi (pixels per inch)
80 ppcm (pixels per centimeter)
Display area

The percentage of the approximate area, taken by the active part of the screen, to the total front area.

80.17 % (percent)
sRGB

sRGB is a color space, developed jointly by Hewlett-Packard and Microsoft in 1996. It is used in different devices such as printers, displays, TV sets, cameras, etc. The sRGB color space covers about 72% of the NTSC color space.

100 % (percent)
Adobe RGB (1998)

Adobe RGB (1998) is a color space, developed by Adobe Systems in 1998. It has a wider gamut than the sRGB (mainly in the cyan-green range of colors) and is widely used in professional printing.

99.5 % (percent)
DCI P3

DCI P3 is a color space, introduced in 2007 by the SMPTE. It is used in digital cinema and has a much wider gamut than the sRGB.

99 % (percent)
Brightness

Information about the brightness of the screen. It is measured in candela per square metre (cd/m²).

140 cd/m² (candela per square meter)
Peak brightness

Often even a higher peak luminance can be achieved under certain conditions. For example, when a smaller area/APL of the display is used for showing a bright object, when a bright object is displayed for a short time, etc.

335 cd/m² (candela per square meter)
Static contrast

The static contrast shows the ratio between the brightest and the darkest color, which the display can reproduce simultaneously, for example, within one and the same frame/scene.

10000000 : 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.

HDR10
HLG (Hybrid Log Gamma)
Horizontal viewing angle
