I managed to get the LG B8S. I’ve wanted an OLED TV for so long and finally it’s become a reality. ?
As of yet, I’ve just tested an NTSC PS1 game and I could get 5x on it. I’ll do some further tests with some 576/480 consoles this week and see if they will line double properly.
UPDATE: Passthrough, Lx2, Lx3, Lx4 and Lx5 all work on the LG OLED B8S. SNES also works, but for me it was having slight issues with dropping out on 60Hz Lx5, though I have yet to mess around with the sync settings. I tried the both Dreamcast (with Toro) and Xbox, both can line double to 960p with no issues.
