I have been facing a persistent issue with my Dell Optiplex 9020 system equipped with an RX 470 graphics card. The problem started a month ago, where the monitor displays a black screen when connected to the graphics card using a DVI cable. The monitor is working correctly as it functions well with another system. However, when using the integrated graphics, the system works without any issues. Moreover, remote display access using Google Remote Desktop shows that the computer can be seen functioning correctly.
Troubleshooting steps I have already attempted:
Tested the monitor with another system, and it works flawlessly.
Confirmed that the monitor and PC are powered on and functioning properly.
Replaced the cables connecting the monitor and graphics card, but the problem persists.
Updated the BIOS and reinstalled the graphics drivers, which resolved the issue temporarily. However, the problem returned after shutting down the system.
System Details:
- Dell Optiplex 9020
- Graphics Card: RX 470
The issue has been ongoing for a month, and I have been using this setup without any problems for over a year before this occurred.
I would appreciate any guidance or suggestions on how to resolve this perplexing issue. Thank you in advance for your help!
