Troubleshooting the VGA Output Resolution
1. To troubleshoot the VGA output resolution, you first need to
check the VCFX Out Resolution values, as follows:
a. Access the Hardware Information screen on the
ViewStation FX ( System Info>Admin Setup>
Software/Hardware>Hardware ). This screen displays the
VCFX In Resolution and VCFX Out Resolution values.
b. Make sure that the resolution values:
• Match the output resolution reported by your computer.
• Match the approved values.
• Are equal.
2. If the resolution values do not match or are not equal, change
the output resolution and frequency on your computer to the
correct values, as follows:
a. Disconnect the Visual Concert FX power supply.
b. Change the resolution.
c. Reconnect Visual Concert FX. Once Visual Concert FX
reboots, start the presentation again.
d. Check the resolution reported on the Hardware
Information screen.
3. If the problem persists, reboot Visual Concert FX by holding
down the
Stop and Play buttons simultaneously.
Checking the Computer VGA Output Resolution
You can also connect the VGA output from your computer directly to
a VGA monitor, and check that the computer’s reported output
resolution actually matches the output to the monitor. To do this,
perform the following steps:
1. Connect the VGA monitor directly to the computer.
2. Set the computer display resolution and the VGA monitor’s
resolution to the same values.
• If the display appears correctly, skip to step 3.
• If the display does not appear correctly, change the VGA
output resolution of your computer until the display on the
monitor appears correctly.
3. Reconnect the computer and VGA monitor to Visual Concert
FX.
