Hello, I'm curious if anyone has successfully connected their gaming PC to the Epson LS12000B. On my machine it appears as a 4K 120Hz display, yet no signal is detected. It only functions at 4K 60Hz. I've tested various cable types—short copper and long optical rated for HDMI 2.1 8K 60Hz and 4K 120Hz. I've also tried premium cables from different brands. In the Epson settings, I attempted to switch to HDMI eq level low. I used Windows built-in resolution settings and the NVIDIA control panel, which defaults to 4x2K 60Hz as native and restricts changes until I pick 4K directly, showing only 100 or 120Hz options. Someone might have a better solution or recommend purchasing verified cables.
