you mention Hopper 3. Next, how do you wire from the Hopper to your TV. Is there an AVR in between.
OK, as far as the AVR, yes and no. I've had the LG 4K for just going on a year. My audio is going through an old Bose V35 AVR from when 1080p was the gold standard. At first I went directly from the H2 (now H3) to HDML #1 on the LG. Went optical from the LG to the Bose. I've had all sorts of lip sync problems doing this. I know you can adjust it with both the LG and the Bose but it wasn't consistent, I'd be adjusting nearly every program. The solution was, and I hesitated because I was afraid of over processing. I went from the H2 (now H3) via HDML to the Bose which up converts to 1080p to the LG which up converts to 4K. Over processing turned out not to be an issue and my lip sync problems when away.
All my 4K content was coming, prior to finding out about Ch 540 directly through the LG (Netflix, Amazon, YouTube, Plex . . .) So the setup is: H3 to Awakelion 1x4 4K splitter. Output one from the splitter goes to LG HDML #1; Output 2 of the splitter goes to Bose HDML #1; Bose output goes to LG HDML #4. (LG#2 is AppleTV 4K, LG#3 is open) 4K content is coming into LG HDML #1 which the audio is routed to the Bose by optical connection, so any 4K video is not going through the AVR. All other content is going through the Bose via LG HDML #4.
Here's another head scratcher. I have 3 Vizio TVs (2 4K, 1 1080p) connected to the H3 via a separate dedicated network. Each Tv has 3 wires. Coax OTA, Cat 5 Internet and Cat 5 H3 distribution network via Mactis HDML over Cat system. I'm coming out of the H3 component ports to a component to HDML converter out to the network. I can't get dolby digital out of the H3 to work in the HDML over cat system (it's suppose to but it doesn't) I'd get audio only if I turned dolby off which is not happening. The analog RL out into the HDML converter worked just fine. I also have the added benefit of no handshake issues when you turn the remote TV's on or off so I've been happy feeding the remotes via component. I forget why, but with the H2 there was an issue when I had all resolutions turned on so I had dumbed it down to 720p which cleared up the issue. When I upgraded to the H3 I followed suite.
When I started playing with Ch 540 a week or two ago, I switched the H3 to 1080i, 1080p, 4K resolution and haven't changed it back. Remote system has been working fine. 2 nights ago during one of the baseball games, I was watching channel 540 on the LG. My wife went back to the bedroom and turned on one of the remote TV's. I figured that it would choke the remote system (and require a reset) but no, it was playing in 1080p and the Vizio was up converting it to 4K. It didn't look as good as the real thing but it wasn't far off. I'm very pleasantly surprised that the H3 is spitting 4K content out as 1080p on the component output. Go figure
