20" LCD Monitors Roundup Part VI

Date: 2008-6-14

[Abstract]
   This roundup covers six 20-inch LCD monitors. These are mostly inexpensive models for the office environment where a super-fast matrix and a glossy case may be not only unnecessary but ...

The monitor has 100% brightness and 50% contrast by default. I achieved a 100nit white by lowering both to 41%. You should not increase the contrast setting above 45% as it leads to a loss of lights. The monitor regulates its brightness by means of backlight modulation at a frequency of 209Hz.

Color gradients are reproduced normally at the default settings but get striped when you lower the contrast setting.

The monitor’s color gamut is exactly the same as that of the above-discussed LCD203WM. Their matrixes must be identical indeed. The color gamut is close to the sRGB space but with a more conspicuous shift of the red point towards orange hues than in most other monitors.

The gamma curves indicate that the monitor’s contrast is set too high by default. The lightest halftones are indistinguishable from white. You should keep the monitor’s contrast setting below 45% (it is 50% by default).

The mentioned problem disappears at the reduced brightness and contrast. The curves are neat and close to the ideal curve for gamma 2.2. There are no problems with darks or lights.

The white brightness is uniform. When the screen is black, the sides are darker than the center. This is confirmed by the numbers: the average non-uniformity of white brightness is 5.4% with a maximum deflection of 11.5%. For black, the average and maximum are 6.4% and 18.1%, respectively.

The color temperature setup is worse than in the previous model. Even if you don’t count in the temperature of white (it differs greatly from the temperature of gray because the monitor’s contrast is set too high by default; this problem disappears when your lower the appropriate setting), the picture is cold. The temperature is over 8000K in the Native mode and 9300K in the sRGB mode (although the sRGB standard requires a color temperature of 6500K). In the remaining modes the monitor yields a downright bluish picture.

So if the picture on the screen of the LCD205WXM looks too cold to you, you have to select the user-defined mode and try to adjust the color temperature manually by means of R-G-B sliders.

On the other hand, the monitor has a small dispersion of temperature between the levels of gray, so when you achieve the image tonality you need using the manual settings, you will also get an accurate color reproduction.

The brightness and contrast parameters are just as good as those of the previous model. The monitor boasts a superb contrast ratio even at a low brightness of white.

The LCD205WXM doesn’t have response time compensation, so we can’t expect any records from it. The average response time is 12.7 milliseconds (GtG) with a maximum of 23.9 milliseconds. That’s not fast but comparable to other 5ms monitors.

Comparing the MultiSync LCD205WXM with the above-discussed AccuSync LCD203WM, the former is superior as its stand supports height adjustment while its digital interface solves the problem of image sharpness.

Highs:

  • Good color reproduction setup (for this product class)
  • Screen height adjustment
  • High contrast ratio

Lows:

  • The image is too cold at the default settings
  • No factory-set image modes
  • Slow matrix
  • Poor ergonomics of the menu

Recommended usage:

  • Text-based applications (documents, spreadsheets, Internet)
  • Viewing and simple editing of photographs (if you adjust the color temperature manually)
  • Movies and games that do not require a fast matrix
