JVC LV-N402 Instruction Manual page 29

The new graphics card doesn't get recognized as new hardware.
Check the followings:
• The graphics card is not inserted all the way in the slot.
• An older version of the display driver may have been installed. Uninstall the existing
driver before installing the latest one.
• A non-NVIDIA card may be conflicting. Remove it.
• Check Device Manager. If the Other devices section shows "[ ] Video Controller
(VGA compatible)," the graphics card is detected. Install it from there.
I can't install the display driver for this card when a non-NVIDIA card is installed.
Remove the non-NVIDIA card once, insert LV-N402WA, install and set up the display
driver for it. Now remove it, insert the other card in another slot, install and set up a
display driver for it. Put LV-N402WA back into the slot where it was inserted.
My computer freezes at Windows Startup when restarting after driver installation.
It can happen when a non-NVIDIA card coexists. Remove it once, insert LV-N402WA,
install and set up the display driver for it. Now remove it, insert the other card in
another slot, install and set up a display driver for it. Put LV-N402WA back into the slot
where it was inserted.
The screen blacks out at Windows Startup when restarting after the driver is installed.
Check if the video signal is output from another graphics card.
My computer freezes at Windows Startup when I try to add another card after setting
up this card.
Remove LV-N402WA once. Insert the other card in another slot, install and set up a
driver for it, and put this card back into the slot where it was inserted.
Another NVIDIA-based card does not work after the driver is installed.
Check Device Manager. If the Other devices section shows "[ ] Video Controller
(VGA compatible)," the graphics card is detected. Reinstall it from there. Or reinstall it
using the Found New Hardware Wizard.
Would it be a problem to use another driver for a coexisting NVIDIA-based card?
Yes, use the same driver for it as for LV-N402WA. If the other card does not work,
contact your dealer.
Another driver file of different version exists.
It can happen when the driver is installed by overwriting the old one. Uninstall the old
driver completely before installing the new one.
Any other measures for multi-display-related problems?
Try the followings as preventive measures:
• Use the CMOS switch on HP/Compaq computers.
• Set the system BIOS's primary video setting to PCI Express.
• Install cards one by one.
• Check the card for the secondary monitor(s) if it can be used for secondary monitors.
• Update the computer motherboard BIOS.
• Update the chip set driver on the computer.
• Update the driver for a non-NVIDIA card.
• Use a different slot.
• Change the driver version.
