Geometry: The geometry on
the KDS's display is excellent, all lines are perpendicular and
straight.
Brightness / Contrast:
There is good separation between the dark black shades as well as the
lighter shades. The blackest shade is very dark and the whitest shade is quite
bright.
High Voltage: During this
test we noticed the external trace line bending very slightly. This motion was
most visible on the vertical line, though it was also slightly seen on the
horizontal line.
Colours: White is very
pure and bright, no red or blue tints. The horizontal dampening wires are
visible on the white background. Red seems a bit washed out, and could be more
vibrant. Blue and Green are excellently reproduced and very vibrant.
Convergence: The corners
of the display start to show the effects of lost convergence as the red and blue
colours begin to deviate from the edges of the white grid. The blue colour is
most visible on a pink grid, red is visible on the yellow grid and on the
red-green-blue grid the blue is visible off center at the very
corners.
Focus: Focus is very good
in the corners where it can often become blurred.
Resolution: While looking
at a pattern of vertical and horizontal variously sized lines the vertical
lines appear slightly blurred together in a consistent fashion over the entire
real estate of the display. This not overly significant however.
Moire: The KDS exhibits
excellent moire except when the test moves to a solid screen of vertical 1 pix
black and white lines. The lines appear blurred together. 1 pix horizontal lines
are perfect and the 1pix squares start to show signs of the shadow
mask.
Readability: As with most
displays the text is sharpest at the very center, and very good at the
corners.
Jitter: None
whatsoever.
