Bought it. Returned it. for a brief weekend I owned the 75 SM90. This TV is Shakespearean as it's the best of times and the worst of times. First the good: the video processor is top notch. DirecTV looks terrific. I saw little to no DSE when watching a DVRd Stanley Cup Final game and a Super Bowl re-run of New Orleans vs Indy was top notch with uniforms looking gorgeous and the grass looking like you could touch it. Watching 4k on Netflix was a good experience. The OS is superb and I like the magic remote. The TV looks very nice and it feels well built. Great to have the most up-do-date HDMI although I think that caused a major problem (see below).
However, there are some detractors that are insurmountable (that could be leading to the already-massive price cuts on the 55 and 65-inch models): as often stated, the black levels are embarrassing. For its flagship LED TV, LG should've gone with a VA panel. The blacks are so bad my girlfriend said (without prompting) that it looked like the actors were in a cloud. I tried all adjustments available including cycling through all of the local dimming options. To level set, I played The Martian and John Wick on a Panasonic DP-UB820-K routed through a Denon AVR4400H receiver using compliant HDMI cables. For comparison, I tried a 2019 65-inch Vizio Quantum G1 with a VA panel that evinced superb blacks. While I loved the 4k UHDs on that set, the DSE while watching hockey was unacceptable. There was a perceptible block of very slight gray that occupied a symmetrical middle of the screen when the cameras panned back as the players were exiting zones and passing the puck forcing quick pans of the cameras. So the Vizio went back and I bought the 75 SM90 though I had serious misgivings about its black levels. In other words, I took a flier.
I tinkered with the calibration settings from Rtings for this set's predecessor since they have not reviewed the 2019 version yet. Nothing worked. The black bars were gray in many scenes. The blooming was awful. And it looked like beams of light coming through the screen on very dark scenes. It was unwatchable as a movie monitor.
The second issue may be an HDMI 2.1 problem...not sure since I've found nothing on this online. But when I turned on my DirecTV DVR, as routed through my 4K-compliant Denon, I got zero sound through my receiver. Nothing. I tried everything from re-setting the box to re-setting the Denon to messing with the speaker settings on the TV's menu. Zippo. There was a brief second after cycling the DVR back on that showed a message stating that the component did not have sufficient copy protection. Not sure if that was it or not because the message went away almost instantly. But this was clearly as show stopper as I have no interest in using ARC for audio given that I have all of my components running through my receiver to ensure Dolby Atmos and lossless audio compatibility. My Panny blu-ray player? No problem. My Roku Elite? No problems passing audio. But my HDR24 DirecTV receiver was rendered mute and for that matter moot.
In conclusion, I went to BB yesterday and got the 75-inch Sony XBR900F and it's everything I could want. Excellent black levels and superb video processing. While its remote blows and its OS is wonky, it's a superb set and I'm glad to have it mounted in my theater. To put the similarly priced SM90 next to the X900F should create a source of embarrassment for LG. Their IPS panels simply cannot hold a candle to the VA panel in the Sony and Samsung owners would likely have the same experience if watching the LG. If off-access viewing is that important then prepare to give up a ton of picture enjoyment for the sake of other people watching a mediocre-at-best set.
Caveat emptor: the LG is an underwhelming choice to say the least.
