Evaluation Criteria

Pcstats TFT Display Evaluation Criteria:

We evaluate the quality of the TFT display with a program called Nokia Monitor Test. The software application displays a range of colours and test patterns that can help diagnose just about any visual problems or defects a TFT display may contain. It can also be a very useful tool for properly adjusting a display to the correct settings. The software consists of eleven tests which can be run in steps as adjustments are made to the OSD. As the tests are run we look for the following problems, only one of which should be inoperable (broken pixel).

  • Broken Pixels: What we class as a 'broken pixel' can fall under any one of the following circumstances: Pixel always on (any colour), pixel always off, pixel unable to display a shade (red, green, blue, black, white), pixel shown colour gradient.
  • Pixel Clock: If the number of dot clocks within one horizontal synch are not properly configured the screen will appear to drift or vertical stripes may be generated. This should be correctable by the on screen menu.

    Improperly adjusted screen. Vertical stripes. Properly adjusted. Consistent image.
  • Phase: If the phase of the display data and dot clock are not correctly tuned the screen can flicker, or text be displayed blurry. For example text may appear dithered, or when looking at a test pattern of a one-pixel black, one-pixel white checkerboard pattern the pattern may be distorted. This should be correctable by the on screen menu.

    Text dithering effect by either phase adjustment problems, or lower than optimal resolution settings. Sharp text is displayed with monitor on best resolution setting.
  • Response Time: We look for any streaking associated with moving a full page of text up or down quickly. Displays with slower refresh rates tend to show some degree of image streaking or text discoloration which can be distracting.
  • Stand Stability: TFT displays are fragile components and the stand should offer adequately stable support as well as be easily adjustable.

    We deduct marks for quality control if there are any predominant broken pixels in a display. While many manufacturers may consider a few broken pixels acceptable, we believe the high cost of TFT displays should translate into a clear and unblemished image.
