With working in VGA mode, this unit allows you to perform several adjustments.
You may find that images blur, depending on the clock phase of your PC's Processor. If you
experience blurring ,
you can obtain a clearer image by adjusting the phase setting.
Adjust the clock frequency of the set's internal clock signal. If shimmering or rainbow-like
noise is apparent in
the image, try adjusting the frequency setting.
