SPECIFICATIONS ARE SUBJECT TO CHANGE WITHOUT NOTICE
The video monitor image is distorted.
This often occurs where some of the areas of the image are very dark and others are very bright. These
extreme changes in the image are difficult for your video monitor to deal with. Try adjusting the contrast
and brightness settings on your video monitor to rectify the problem. On some TVs (usually old ones),
this effect is unavoidable as they may not be designed with computer images in mind, and therefore
show 'bowing' at the sides for some graphic images. The only solution is to adjust the brightness and
contrast on your video monitor - the unit is not at fault and cannot correct problems with your video
monitor.
If the problem persists it may be due to the screen size settings, try adjusting the image and its position
on the screen.
Some colors come out incorrectly on the video monitor.
Try altering the color, contrast, and brightness settings on your video monitor. These are usually set up
for viewing TV programs, which is very different from viewing computer graphics.
If you are using the RGB video output from the unit make sure that the cable is correctly attached to both
the unit and the monitor.
If you have altered the ADC Ref. value to too low a value, then this may make yellow appear very
washed out and even white. In some circumstances, it can cause flashes within solid green areas. Do a
Factory Reset to restore the original settings (see earlier in this manual on how to do this).
How can I reduce smearing?
Smearing usually occurs on Composite Video connections, and is generally unavoidable -unless you can
switch to using S-Video or RGB connections (see connection details on page 4). It occurs because the
brightness and color information is transmitted as one signal, and the two parts have to be 'bandwidth-
limited' to avoid them interfering with each other. Using good quality video cable will help towards
reducing this affect.
S-Video will give far less smearing than composite video, but RGB will be better still.
How do I use the unit with a VCR?
Connect one of the unit's video outputs (probably the Composite Video lead, or maybe the SCART lead)
to the VCR's input. Note that you won't be connecting to the Antenna / Cable TV input on the VCR, but to
one of the VCR's auxiliary (AUX) inputs, so you have to therefore tell the VCR which input to use - often
it's channel 0, or AUX 1, AUX 2, etc.
Why don't I get better VHS recordings when using a SCART lead?
Whereas your VCR might have a SCART connector, it will not have the RGB pins connected on it - and
will simply use the Composite Video signal instead - so you won't get the true benefit of RGB.
