Check for failures during the handshake when using Elgato 4k 60 capture.
I'll begin by addressing the most frequent fixes:
- Cable connections are secure. Verified and replaced.
- Monitor functionality is confirmed. Tested across various PCs.
- GPU operates smoothly. Standard monitor functions perfectly.
- Drivers and system updates are current.
The problem here involves your Elgato 4k60 PCI-E Capture card connected to your Ugreen HDMI Switcher, which then feeds into your main monitor. Your secondary monitor is linked directly to the GPU. You've maintained this configuration for six years without issues. Recently, you upgraded your monitor from an LG 24GN600-B to a BENQ RL2755-B. The LG works flawlessly, but with the new BENQ, you experience "No Signal Detected" when switching monitors. The PC runs with two screens, but the BENQ display shows no video output. The monitor settings only list input ports without any additional options. When you connect the BENQ to your laptop, everything works perfectly.
Could there be a solution for this issue?
I tried my best to figure it out, but I haven’t made any headway. It’s unusual for me, so I’m unsure how to fix it. Thanks for your help.
Attempting this again, since I still don't have an answer for it.
I didn’t need to start another thread; I’m just bringing it up. This is really bothersome—I don’t think anyone else has encountered this problem before.
