OSD and Display Evaluation Notes
have maintained a very concise OSD menu system for
the last few years and the 172X continues the tradition. Navigation with the keys
on the control panel is straight forward and should be easy even for the most
novice of users.
The OSD menus cover the
following settings: Brightness; Contrast; Image Lock: Coarse, Fine; Position:
H/V; Color Control: Red, Green, Blue; Color Reset: Geometry, Color; Image Size:
Normal, Expand 1 &2; Image Effect: Scaling on/off, Filtering; Language:
English, German, Spanish, French, Italian, Swedish; OSD Position: H/V; OSD
Display Time: 5, 10, 20, 200 seconds; and Display Mode: Hl/V Frequency &
Magic bright is in a separate menu and consists of four settings: User,
Internet, Text and Entertainment.
The user and entertainment settings are brightest making it ideal for watching a
movie for example. As with all LCD's capable of analog-input, the
best way to configure the screen is use the "Auto Adjust" key and just sit
|PCstats TFT Display Evaluation
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. The software consists of eleven
tests which can be run in steps as adjustments are made in the OSD.
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. 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.
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
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.
