11.4 There is excessive flicker on the Output.
Try using a different Flicker reduction mode. Turning the contrast down and the
brightness up on the output device can have a large effect on flicker. Or try adjusting
the brightness and contrast of the source input by selecting the Input adjust menu.
11.5 The Output image is distorted.
This may occur where some of the areas of the image are very dark and others are
very bright. The solution is to adjust the contrast and brightness settings on your
Output device to rectify the problem.
Alternatively, if the Adjust resolutions menu has been used to the output resolution in
question, a firmware update is recommended to perform a FULL factory reset.
11.6 Some colors appear to be incorrect on the CV/YC output
First try altering the color, contrast and brightness settings on your TV or video
display. These are usually set up for a very different reason than viewing computer
graphics and may need changing to suit. If you cannot achieve exactly what you
desire then alter the inputs levels in Adjust sources until the correct colors are
restored.
11.7 How can I reduce color smearing on CV connections?
Smearing usually occurs on Composite Video connections and is generally
unavoidable - unless you can switch to using S-Video or RGB / YUV connections. It
occurs because the brightness and color information is transmitted as one combined
(composite) signal and the two parts have to be 'bandwidth-limited' to avoid them
interfering with each other – which then reduces the quality.
11.8 I can no longer adjust the Output image resolution.
When the unit is in Lock mode, the output resolution is fixed to be the same as the
Lock source input resolution. During this time the Output image menu item is not
displayed.
11.9 The picture on the video display is black and white.
Ensure that all the cables are correctly connected. If you are using a PAL TV to
display the output then the unit may be providing resolution set to NTSC mode, or
vice versa.
11.10 The picture on the video display is green.
The Output type is probably incorrectly set to YUV mode, whereas you are
connecting to an RGB monitor – see Adjust outputs menu.
