Just bought the LG Nano91 primarily for gaming and it’s been great. I have a PS5 and Series X connected to ports 3 and 4, respectively. I’m able to access all settings on port 3 with the ps5 (game mode and HDR game mode). But on the series x, port 4, some of my settings are grayed out in both games modes. For example, local dimming is grayed out at low. Any idea why this is?
