Bought an OLED55E6V a couple of months ago and absolutely love it. Having blown more than £2.5K I will have to raise my persuasion game to a new level to acquire a suitable sound set up to match and that will probably be well after Christmas. In the meantime the built in soundbar is good, BUT, as the question says, what is OLED surround supposed to do? I have it turned on, with the mode as Standard(user) and I can't detect any difference at all, on or off in any sound mode, with any source. The manual is painfully limited. Am I missing something obvious. Quite happy to appear dim - I'm just curious.
