The second screen only shows data when the BIOS starts up
The second screen only shows data when the BIOS starts up
I've been facing this issue for some time now. Usually, turning off both monitors and plugging them back in resolves it. However, today it didn't work. The second monitor only shows a signal during the BIOS splash screen, and once the PC powers on, it displays "no signal." It seems like a software problem might be at play, since the splash screen indicates both the cable and adapter are functioning correctly.
Potential useful details:
- Operating system: Windows 11
- CPU: i7 14700K
- GPU: RX 6600
- RAM: 64 GB DDR5
- I’m aware the GPU is heavily mismatched with the CPU, but my main concern is a strong CPU and RAM for work, while a top-tier graphics card isn’t budget-friendly right now.
- Second monitor uses an HDMI to DisplayPort adapter; it worked before.
- Graphics drivers are up to date.
- The issue appears even with the same driver version that previously functioned well.
- Both monitors are connected via the graphics card, and I double-checked connections.
- Swapped cables, tried different ports, and changed adapters—still no success.
This is really frustrating! I’m hoping someone can offer a solution. I really value this community’s help.
Have you verified the Windows settings and confirmed it displays two monitors? -This seems unlikely but let’s proceed gradually before needing to swap components. -Next attempt using the cable without the adapter, then check if the issue persists. -We’ll isolate whether the problem lies with the adapter or the cable itself.
Hey! I verified in Windows, but the second monitor wasn't showing up. I fixed it by reinstalling an older display driver version, and I had to plug and unplug the monitors again. It seems a bit suspicious and just a quick fix. I wish I could find the root cause someday!
The splash screen appears on both displays when the monitor mode is configured as Duplicate in Windows Settings. This has occurred before.
I configured it as an extension today. When I powered on my computer, the issue repeated. I’m getting really frustrated! Maybe I should purchase a monitor with a DisplayPort port and stop dealing with this problem.
They doubt DisplayPort will resolve the issue. Confirm it remains active in Extend. Overall, it shouldn’t be too severe.
It might be a compatibility issue with your graphics card or possibly an operating system problem.
