LG terminated support for „DTS“ sound, because they decided that the marked share for DTS is too low. Thats what they wrote to a friend of mine last week. One reason more that an AV-Receiver should work fine with the LG tv.
After 2 german media websites (golem.de / heise.de) reported about the dolby vision problem, the dolby support wrote me that there will be an update next week, probably monday. And then it should be fixed… hope for the best
