Has anyone gotten ARC to work on this TV with a denon 791/1911? I've tried everything I can think of and can't seem to find much documentation on the subject. I set ARC mode on LG 55LW5600 to on as well as simplink. I should note that even with simplik on all the options are greyed out. My Denon AVR 1911 is set to the TV input and has HDMI control set to on. I had no luck with my "non-ethernet" HDMI cable so I bought one "with ethernet" from Amazon (media bridge part # 91-02X-15B) and I still can't get it to work. FTR, I'm not really buying this ethernet option since so many have posted using ARC with "non-ethernet" cables and I haven't seen conclusively that there is an addition pin for ethernet. But I'm not overly educated on the subject and I'm sick of screwing with this so I'm HOPING that someone else out there has some info that can help me start elimiating variables..... Any help is appreciated. Thanks also for all the other great info I've been getting from this thread!
