Wrong EDID for LG OLED65B7P nvidia 390.42 linux 3.10.11 arch

I can’t seem to drive my 65inch LED OLED at 60 or 120 hz for 3840x2160. It claims to support 120hz for 3840 but that’s not an option in nvidia-settings. Does not work setting 60hz in xrandr or gnome display properties. However, it was working before, when the EDID was detected differently. Before I think it said Goldstar Electronics 11", now it says 72". See: https://bbs.archlinux.org/viewtopic.php?pid=1775256#p1775256

I was able to fix it by disabling “HDMI Deep Color” in my TV settings.
