Got my C1 delivered yesterday. Best Buy delivers to your room of choice but that's it unless you pay for installation. They barely were able to get it down the stairs with the turn at the landing. After they left I opened the box and plugged it in to make sure it worked. My son came today for the weekend, and we mounted it, grilled some steaks, and sat down to check it out this evening.
Screen tearing, I think the term is. The first description we came up on our own was "Distortion band". It's basically a line across the screen (at times) and just below it the screen is distorted. It may have something to do with motion. Where is the crying emoji?
Tomorrow I will try a different cable (bought a new one from Crutchfield just for this) and a different Firestick (tried a Firecube that worked fine on the previous TV) and check out a Screen Test utility that LG apparently has. One of these will fix the problem, or the TV goes back. NFW I pay $2600 for this. Not mad yet. Just tired.
You were correct in trying a new HDMI cable. Get one of the "ultra high speed" HDMI cables which can handle at least 40Gbps. Also, if you haven't done so already update the firmware on both your TV and AVR. The TV probably updates automatically when first plugged in. What AVR are you using? How old is it?
Last week a friend of mine bought a TCL 65S635, which is a 65" Roku TV. He had connectivity problems, as if the TV could not "see" the cable box. Got an error message, "No cable signal, is it on?" He called the cable company and they send out a guy that convinced him the TCL TV was to blame. "TCL TV's have connectivity problems", the guy said. Back it went to the store for a Sony X90K. He got the Sony hooked up, realized it was Google TV, not Roku, an annoyance but not a deal breaker, and didn't like the picture quality.
I was called over to troubleshoot, and yes, no matter how the picture was adjusted, it simply looked washed out and lackluster when viewing streaming channels. Viewing the cable channels it was fine; viewing over-the-air channels with an antenna looked excellent, viewing streaming content, any channel, and it looked washed out. Blacks were not deep black, they were dark gray; picture was not sharp, etc. Then, at one point when watching a baseball game on cable, the audio went out. Unplugged TV for 30 seconds, replugged in and audio was restored. At this point he realized he couldn't live with the Sony. He went on and on about how excellent the picture on the TCL looked compared to the Sony and "if only the TCL would connect properly."
When I was there I noticed he had the cable box connected to the eArc HDMI input. Also, when I hooked up his HDTV antenna I noticed there was a coax cable hooked up to the antenna input of the TV. This was connected to the cable box. So an HDMI cable AND a coax cable was running from the cable box to the TV. I asked him why it was connected in this manner and he said it was because that was the way the cable guy had connected it. <shaking my head> He said the cable guy was adamant the cable box MUST be connected to the eArc input.
We went and bought the same TCL 65" TV at a different store, I hooked it up properly and he's very satisfied. Sony goes back today.
