Is there a display port issue when the system boots, possibly related to the GPU port?
Is there a display port issue when the system boots, possibly related to the GPU port?
Issue Overview:
PC starts up with a black screen (no DisplayPort signal). A hard reset resolves the problem, but it keeps happening. While using the device, the DisplayPort monitor occasionally loses connection for 3–5 seconds, three to five times daily, whereas the HDMI monitor functions normally.
GPU Specifications:
RTX 2070 Super
Power Supply: Recently upgraded from an old 11-year-old unit to a new Gigabyte GP-UD750GM (750W, 80+ Gold).
Monitor: Tested with various DisplayPort cables and ports; a new monitor was purchased due to suspicion about the previous one.
Symptoms:
At startup, no signal appears on the DisplayPort connection. During operation, the DisplayPort display briefly disconnects for 3–5 seconds, occurring 3–5 times per day. HDMI remains unaffected.
No crashes or visual glitches during gaming (maintaining 70 FPS in Battlefield 6). No driver issues detected after a clean reinstall via DDU.
Power Supply: Old 550W PSU replaced with a new 750W Gigabyte model. Power consumption is stable, no fluctuations observed with a smart plug.
Troubleshooting Actions:
- Cables and Ports: Used multiple DisplayPort cables; tested all ports on the GPU; HDMI confirmed fully functional.
- Power Supply: Updated PSU and monitored for voltage stability.
- GPU and Drivers: Performed driver reset and updated to latest NVIDIA versions. Re-seated GPU and verified PCIe power connections.
- BIOS/System: Reset CMOS, confirmed proper GPU placement in PCIe slot.
Monitor Tested:
The monitor was tested with another device and functioned correctly.
Potential Explanation:
The DisplayPort connection on the GPU appears to be defective or deteriorating, as the problem is limited to DisplayPort and remains consistent after eliminating cables, drivers, power supply, and monitor issues.
Uncertain about that specific model, but I'd be happy to try replacing it with another option, especially one outside of Gigabyte.
