Hi there, I just got a new LG OLED55B7D and was setting it up with my NAD T748. Everything works as expected but NAD’s OSD menu is giving me a headache. I’ve read about problems with Samsung TVs in other threads (something about unsupported resolution) – maybe the LG has a similar problem? When I press the (OSD) menu button on my NAD remote the TV switches into PCM/576p mode, but the screen stays black. Then a message pops up reading something like "no signal found". I tried every possible combination of HDMI cables, different HDMI inputs in the TV, different (TV) HDMI setups (CEC/ARC/SYMLINK enabled) but to no avail... As a last resort I thought about buying a small display, just for the admin stuff but maybe... maybe someone here solved this puzzle already? Thanks!
