1.3 Getting the Best Results

There are many factors affecting the quality of results when scaling video signals.
Some basic precautions will ensure the best possible performance from this
product.

Output Display Device – The quality of the output signal will depend largely upon
the type and quality of display device used. For instance, some video projectors
just look better than others.

Using Native Resolution – It is always best to set the output resolution of the
scaler to the native resolution and refresh rate of the display device. This allows
this allows the unit’s scaling engine to do most of the work, which usually results in
a superior picture.

Distance between the Video Scaler and the Display Device – This plays a
major role in the final result. Long distances are possible, but special measures
should be taken in order to avoid cable losses. These include using high quality
(coax-type) VGA cables and premium DVI cables such as DVIGear’s Super High
Resolution™ cables. Line amplifiers or repeaters may also be necessary.

Output Connection Cables – Low quality cables are susceptible to interference.
They degrade signal quality due to poor impedance matching and cause
elevated noise levels. Therefore, cables should be of the best quality. Coax-type
computer cables are recommended because of their superior internal shielding
characteristics.

Interference from Nearby Electrical Devices – These can have an adverse effect
on signal quality. For example, an older computer monitor often emits very high
electromagnetic fields that can interfere with the performance of video equipment in
its proximity.

DVI-3210a Input / Output Panels

4.1 Connecting the Input

The DVI-3210a can accept both VGA and HDTV inputs. When connecting a VGA
format input, use the provided HD15 (VGA) cable. When connecting HDTV signal
inputs, use the supplied Component Video (3x RCA) to VGA Adapter Cable. The DVI­3210a will automatically detect the mode and resolution of the PC/HDTV input signal.

4.2 Connecting the Output

The DVI-3210a Video Scaler can output a wide variety of PC and HDTV resolutions
both in digital (DVI-D) and analog (DVI-A) formats. To use the device with a DVI-D
capable display, connect the supplied DVI cable from the unit’s DVI output to the
DVI input on the monitor, then select DVI-D mode in the Output Setup menu. This
is the standard configuration for the device. To use the analog output of the DVI­3210a, select the DVI-A mode in the Output Setup menu. You must use a DVI-I
to VGA adapter cable (DVIGear p.n. DVI-8415b) and a high quality VGA cable to
connect the analog output to a VGA compatible display (sold separately).

6.0 TROUBLESHOOTING

Other than checking for faulty cables, the most common problem is choosing an
incorrect Input or Output Setting. Make sure the display is capable of handling the
resolution and refresh rate selected. Also be sure to use the correct type of cable
for the input format selected (YPbPr or RGB mode).
