I'm also thinking about going 4K LG OLED, I would appreciate details of model number etc, maybe you could try the HDR-Fox T2 directly to the LG OLED, as there have been reports of both sound and vision HDMI problems with that combination - maybe a post for hummy arms though, rather than hereI hope to get a LG 4K oled TV later this month.
I wasn't bothered about 20mm - in fact it's irrelevant given the other stuff on the back of the set. It's the picture and sound quality I went for. The blacks are amazing - I watch in a dark room (SWMBO always wants a light on ?!) and when the picture goes black I can't see the TV on the wall ... or the wall for that matter. Our previous plasma set was always a grey panel.why oh why pay the substantial bucks to save the 2 cm of space with oled?
