Geometry:
The 1100P-Plus has good geometry.
There is a slight distortion of the test grid at the top of the screen, and
along the outer edge row to test grid squares. The central region of the screen
is
perfect.
Brightness /
Contrast: Excellent contrast and
brightness. Blacks are very dark while the whites are
vibrant.
High Voltage:
On the three bar test, the trace lines (both vertical and horizontal)
remain absolutly steadfast, as is the case on the full screen component
test.
Colours: Excellent colours in the white,
black, green, blue, green and red test
screens.
Convergence: There was a loss of convergence in
the upper right hand corner with the colour red. On the pink test grid, blue is
off slightly at the outside edges and even partially at the center. The yellow
and light blue test grids show excellent convergence.
Focus: The display exhibited very good focus
in the center of the screen, and good focus towards the outside edges of
the screen - most CRT's have at some problems at the outside
corners, so this is very common if not standard to see. Interestingly we
noticed some very faint shadowing to the right of the test patterns on the white
screen background.
Resolution:
Excellent resolution at the
center of the screen area, and at the corners. As is the
case with most displays, the 1 pixel separated vertical lines showed
some blending effects.
Moire: Excellent moire, no visible image effects
noted.
Readability:
Excellent readability. Again some faint shadowing or streaking was
noticeable on the white background to the right of the test
pattern.
Jitter:
None visible at
all.
