The X203H BD 20-inch LCD monitor belongs to Acer's "ACER V" series of flat-screen personal computer monitors. Two different companies manufacture the monitor's LCD screen: SEC, which uses the LTM200KT03 panel module; and LGD, which uses the LM200WD1-TLC1 panel module. The technical specifications of the Acer X203H vary slightly depending on the type of module it has. Several of these specifications stand out as examples of the monitor's design and performance.

Resolution and Pixel Specs
Display resolution refers to the number and configuration of pixels -- or tiny, illuminated squares -- that a monitor can generate on its screen. The higher a monitor's display resolution, the greater level of detail its screen provides. All Acer X203H monitors provide maximum display resolutions of 1,600 horizontal rows of pixels by 900 vertical rows of pixels, which means a single monitor can generate a total of 1.44 million pixels. The Acer X203H provides a pixel pitch of 276.8 um by 276.8 um per triad. A triad is a reference to a single pixel, which consists of three, differently coloured sub-pixels. Pixel pitch refers to the distance between successive pixels: the lower a monitor's pixel pitch, the sharper its on-screen images will be.
Colour and Contrast Specs
Using its pixels, each of which consists of a red, green and blue sub-pixel, the Acer X203H monitor can display 16.7 million colours. The more colours a screen can display, the more vibrant and realistic its imagery can be. The Acer X203H has a typical contrast ratio of 1,000 to 1 and a minimum contrast ratio of 700 to 1. High contrast ratios, like high colour capabilities, correlate to more realistic on-screen imagery. Contrast ratio refers to the difference between the darkest shades of black and the brightest shades of white a screen can display.
Acer X203H monitors with SEC LTM200KT03 modules have typical viewing angles of up to 160 degrees right and left, while Acer X203H monitors with LGD LM200WD1-TLC1 modules have typical viewing angles of up to 170 degrees right and left. Both modules provide the same up and down typical viewing angle of up to 160 degrees. Viewing angle refers to how far from centre a viewer can be positioned while still being able to see images on a monitor's screen clearly.
