Observing Signal Loss & "No Signal" Issues From Desktop PC to Optoma UHZ50 using LG SN9Y
You're facing a persistent "No Signal" issue with your Optoma UHZ50 projector and LG SN9Y soundbar. The connection has deteriorated over time, despite a previously stable setup. Your configuration includes premium fiber optic HDMI cables and a high-end ASUS processor, yet the signal vanishes completely. The problem appears to stem from either hardware mismatches or driver conflicts. Testing has ruled out faulty HDMI ports on the GPU, motherboard graphics, and DisplayPort output. The audio issue complicates matters further, as reversing the signal path causes cutouts. A clean boot and software update helped temporarily, but not fully. The fact that a work laptop works perfectly suggests the core hardware is sound. Consider checking for driver updates, ensuring firmware compatibility, and verifying cable integrity. If the problem persists, a hardware inspection or replacement of the projector might be necessary.
