27″ Acer ED273 wmidx – Specifications

The year in which this model was announced.

Name of the series, which the model belongs to.

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.

Radius of curvature

There are curved displays, whose curve is part of a circumference (arc). In order to give more precise information about the curve of the screen, often the manufacturer provides data about the radius of this circumference. The smaller the radius, the larger the screen curve.

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.

VAPanel 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.

8 bits (6 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.

YesColors

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.

16777216 colors
24 bitsAspect 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

16:9Resolution

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.

1920 x 1080 pixels
Full HD / 1080pPixel 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.

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.

81 ppi

(pixels per inch)

32 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.

90.67 %

(percent)

Backlight

The backlight is the source of light of the LCD display panels. The type of backlight determines the image quality and the color space of the display. There are various backlights such as CCFL, LED, WLED, RGB-LED, and etc.

W-LEDNTSC (1953)

The NTSC (1953) color space is introduced in 1953 by the FCC with the appearance of color television and has a wider gamut than the sRGB.

72 %

(percent)

Brightness

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

250 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.

3000 : 1Dynamic contrast

The dynamic contrast shows the ratio between the brightest and the darkest color, which the display can reproduce over time, for example, in the course of playing a video.

100000000 : 1Horizontal 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).

4 ms

(milliseconds)

0.0040 s

(seconds)

Coating

Information about the type of coating of the display. There are different types of matte and glossy coatings, each of which has its own advantages and drawbacks.
