one display failed

[IGRAFFMAN]

I recently purchased and installed a NIDA Gforce RTX 2060 Super graphics card to replace the failed graphics card in my HP Pavilion Gaming PC. It worked well from the start. Suddenly, only one monitor displays.
1. Installing the cable from one output port each display results in the display working so the monitors work
2. Installing the cable from the other output port  to each monitor same result. Seems that the card works.
3. Device Manager shows but one Generic monitor.
4. Device Manager -->View-->Show hidded devices show multiple monitors with only 1 highlighted. Any suggestions?

Thanks so very much for any help!

Hi @IGRAFFMAN ,

Welcome to the HP Support Community. 

I'd be glad to help you! 

I understand how frustrating it must be when your new graphics card isn’t supporting multiple monitors as expected, especially after everything seemed to be working initially. Let's work through this issue step by step.

To better understand the problem:

1. Are both monitors set to the correct input source matching the port they’re connected to on the graphics card?
2. Have you recently updated or changed any drivers, software, or system settings that might have affected the displays?
3. Are you using any adapters or converters with the cables, and if so, have you tested with direct connections?

Here are five troubleshooting steps to try:

Check Display Settings in Windows:
Right-click on your desktop and select Display settings. Scroll down to Multiple displays and click on the "Detect" button to see if Windows recognizes the second monitor. Ensure the "Extend these displays" option is selected if the second monitor is detected.

Update or Reinstall Graphics Drivers:
Even if the card initially worked, corrupted or outdated drivers can cause issues. Download and install the latest NVIDIA drivers for the GeForce RTX 2060 Super directly from NVIDIA’s website. Use the "Clean Installation" option during the setup to remove any conflicting settings.

Test with Different Cables and Ports:
Since you’ve confirmed the monitors work individually, try swapping the cables or ports used for each monitor. If possible, use different connection types (e.g., HDMI instead of DisplayPort) to rule out faulty cables or ports.

Reset Display Settings in NVIDIA Control Panel:
Open the NVIDIA Control Panel (right-click on the desktop), navigate to Set up multiple displays, and check if both monitors are listed. If they are, enable them and apply the changes. If only one monitor is listed, the second one might not be detected by the card.

Check Power and Firmware on the Graphics Card:
Ensure the RTX 2060 Super is receiving adequate power from the PSU (check all power cables are securely connected). Additionally, check if there are any firmware updates for the card that might improve functionality or compatibility.

If these steps don’t resolve the issue, it might be worth testing the card in another system to confirm there’s no hardware fault.

Hope this helps! Keep me posted for further assistance

Thank you for the suggestions.  I don't know how to reply to you.  As suddenly as the one display failed, I logged on this morning and both are now working.
