TFT Display Evaluation Notes

PCstats TFT Display Evaluation Criteria:

We evaluate the quality of TFT displays with the help of 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 optimal 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.
  • 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.
  • 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.

    LCD Display Test Overall Test Notes and Observations
    Geometry: Pass

    Geometry remains true to size as we tend to expect. When the screens are set to PBP, the geometry becomes distorted as the signal is augmented at the monitor level, and not the computer.

    Brightness and Contrast: Pass

    The initial 1-9% show a somewhat inconsistent change in intensities - the larger more definite changes in contrast are much better represented here.

    Colour: Pass

    With a screen of this size, colour consistency over the entire area is a real concern. The 240T scores very high here, with consistent coverage, and nice hues of white, red and blue. The green is a little on the orange side, and this may have an effect on colour vibrancy. No dull, or broken pixels were visible.

    Convergence: Pass

    The test grids in RGB illustrate the worst case situations when different coloured pixels must work closely together, and since they comprise different parts of a pixel they do not line up exactly. With a field of view as large as this is it really hard to notice though.

    Focus: Pass

    Very good, all patterns are clearly visible and defined in both the horizontal and vertical axis. Shaded areas were experiencing some walking lines, but after manually adjusting the image lock they all but disappeared.

    Resolution: Pass

    Resolution is excellent at 1920x1200 pixels. The auto adjust key worked well as a first start, but in testing with some of the more difficult patterns it was evident that some manual tweaking was required to achieve the best picture. There is only one frequency available at this size (60Hz) and the monitor indicated the the signal was holding steady at 59.8 Hz so the video card may have been causing some slight hiccups.

    Moire: Pass

    Moire was excellent after the one adjustment was made to the image lock. Previous to this manual setting the more intensive single pixel moire test screens were suffering from horizontal walking lines.

    Other Evaluation Notes:


    With a listed 25ms pixel refresh rate and viewing angles of 80/80/80/80 the 240T is pretty astounding from head on. Looking from large angles begins to show its limitations as the screen takes over a very slight frosted look, with colours appearing de-saturated. Visually, the 240T is great for large screen projects, or imagery, but not necessarily games. LCD's in general are still not quite up to the quickness of CRT's in this respect, although the 240T does have a very good pixel refresh rate of 25ms.
