UltraGear

Model Designation of the model.

27GX790B

Model alias Other known designations of the model.

UltraGear 27GX790B-B

Model year The year in which this model was announced.

2026

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.

26.5 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.

673.2 mm (millimeters), 67.32 cm (centimeters), 26.5039 in (inches), 2.2087 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.

586.75 mm (millimeters), 58.675 cm (centimeters), 23.1004 in (inches), 1.925 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.

330.05 mm (millimeters), 33.005 cm (centimeters), 12.9941 in (inches), 1.0828 ft (feet)

Panel manufacturer Name of the manufacturer of the display panel.

LG Display

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

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.

2560 x 1440 pixels, Quad HD (QHD) / 1440p

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.

0.229 mm (millimeters), 0.0229 cm (centimeters), 0.009 in (inches), 0.0008 ft (feet)

Pixel density Information of the number of pixels in a unit of length. With the decrease of the display size and the increase of its resolution, the pixel density increases.

110 ppi (pixels per inch), 43 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.

91.16 % (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.

99.5 % (percent)

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

335 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.

1500 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.

1500000 : 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.

DisplayHDR True Black 500

Horizontal viewing angle Information about the maximum horizontal viewing angle, within which the image on the screen is of acceptable quality.

178 ° (degrees)

Vertical viewing angle Information about the maximum vertical viewing angle, within which the image on the screen is of acceptable quality.

178 ° (degrees)

Minimum response time Information about the minimum amount of time, in which the pixels change from one color to another. Very often the manufacturer provides the response time for transition from grey-to-grey (G2G).

0.02 ms (milliseconds), 0.0000 s (seconds)

Input lag Desktop monitors and smart TVs experience a latency/lag in visualizing the information. The time in milliseconds that the display needs to visualize the signal input.

1.7 ms (milliseconds), 0.0017 s (seconds)
