|LCD Display Test
|| Test Observations|
Samsung's 172X performs very
well under normal viewing with the 1280x1024 screen resolution. Since the test pattern
is scaled to fit the resolution.
|Brightness and Contrast:
Very nice shading under the gray scale test. The percentage white
scale bars were clear and de-saturated which was good to see. It
was difficult to see a perceptible change between 1% and 2% white
The white, red,
green and blue test screens were very bright and vibrant over the entire screen area.
There were no dull or broken pixels on the display we tested, which is always
a good indication that quality control is doing its job.
The grid test patterns 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
on LCD screens where there is less blending. Since the pixels on the 172X
are 0.294mm in size, the effect is a little more noticeable than a
standard 17" display which uses a 0.264mm pixel dot pitch.
test has a few patterns of alternating black and white boxes with text
in them. In the center of the page are two boxes with 1 pixel
vertical stripes. All test patterns showed up perfectly.
Resolution was excellent at the native 1280x1024 size. Image dithering at a non-native
1024x768 was good; lines were obviously fuzzy, but text was still very
Since we tested
with the analog signal there was some background waves in a
few of the more challenging test patterns here. They were very subtle and would
be difficult to notice unless you looked for them I
Other Evaluation Notes:
Overall the Samsung 172X handled the Nokia Monitor Tests exceptionally
well. For everyday work an LCD display such as this would provide a
comfortable and vibrant platform.
