5. Monitor Setup
This procedure is designed to correct for discrepancies in the video signal due to
analog/digital video conversion by the Monitor. You do not need to follow this
procedure if you have:
•
A CRT monitor connected to the Remote unit through the VGA input
•
A TFT monitor connected to the Remote unit through the DVI input
In these cases, there is no need to adjust the monitor because the video format is not
converted.
Please make sure that you carry out this procedure before Extender Setup (page
37). If you are using a TFT monitor at the remote console with a VGA cable, both the
Extender AND the TFT monitor digitize the video data stream and affect video
quality. By setting up the TFT monitor first, you ensure that you are correcting
discrepancies due solely to the Extender system in the Extender Setup procedure.
1. Connect the Extender system and display the regular desktop in the desired
screen resolution. Monitor setup may vary depending on screen resolution
and/or refresh rate.
2. Display the OSD utility (see page 26).
3. Select the Tools menu option (see page 33).
4. Select the ‘burst’ pattern option. Your TFT should show fine, 1 pixel wide, black
and white vertical stripes over the entire screen. The OSD will stay visible in the
middle of the screen.
5. Depending on the type of TFT, press the ‘AUTO’ Button on the monitor control
panel or select Auto Adjust in the TFT Setup Menu. Refer to the manual
supplied with your monitor for more information.
6. If the vertical stripes are sharp and without jitter or smearing, the adjustment has
been successful. Go to step 8.
7. If the picture quality is not acceptable after the automatic adjustment, you will
have to manually adjust the pixel clock and pixel phase (in this order). Please
follow the instructions in your monitor’s user manual.
8. Press any key to exit the test pattern display.
9. Exit the OSD.
