Long time lurker and infrequent poster, but I've been following this thread since the beginning and will be picking up a 65" Z9F in the early afternoon today to replace a burned in C7 we bought last year. I do not want to derail or devolve this thread into an LCD vs OLED back and forth but feel it is pertinent to the discussion and reasoning for me still choosing to go with the Z9F 65" regardless of some of the "shortcomings" identified by some. In a nutshell, after reading all the posts and available information, I tend to agree with the lengthy post by mzupeman on page 51 and thomasfxlt's way of looking at the Z9F as well. Maybe my opinion will change in a few short hours when I'm judging for myself with my own eyes, so we'll certainly see. Here is my background info:
We originally purchased a 930E that we promptly returned because of several dead pixels right in the center upper half of the screen so we then exchanged it for an LG 55" C7P from Best Buy last year in August as our primary viewing TV for our family room. The picture has been beautiful, defined, and colorful with great blacks and gray / shadow handling (especially with 4K movies and streaming content), although motion processing could be a little better and it have been nice to be brighter in a room that can be both bright and dark, but now less than a year later it has noticeable burn-in and color banding with certain content and color shades on the screen. OLED light and Contrast settings are nowhere near maximum (80) and brightness set to 50. As a family of four, we view a variety of content including DVD / Blu-ray / 4K movies, broadcast TV and streaming content, and even some Playstation gaming. I do watch a certain cable TV news channel pretty regularly which is what is most prominently being retained and burned into the screen (logo and info bar at the bottom) but again, we do use it for a variety of other content regularly. I am also seeing noticeable color banding in certain scenes / under certain conditions that were not there before, both horizontally and vertically. I guess the fact that it took almost a year for these issues to become noticeable and to show up to varying degrees is telling of the variety of use we put it through, but it seems any content that you view frequently (news channels, games with areas of the screen that change little if any, etc) and just regular wear and tear on the OLED can be taxing on the pixels and screen in general, and will at one point or another yield similar results as I see others mentioning similar issues on other websites and A/V forum searches. I can also somewhat notice a difference in the overall brightness of the screen and "pop" of the colors under the same lighting and viewing conditions as I recall a year ago using the same settings. LG claims 100,000 hours of use before overall brightness would be half of what it originally was when new, but now I don't believe it. Between all of us, we use it about 10 hours per day on average and some days for days at a time has gotten no use while away on vacations and just life happening. Mind you that the unit has a screen shift and pixel refresh function that runs automatically after 4 hours of constant use after being shut off or can be performed manually, which I have done periodically before and after the issue appearing with no improvement of the symptoms.
Fortunately for us I purchased the 4 year extended warranty from Magnolia / Best Buy and would never buy any video unit in this price range without it because it explicitly covers burn in and other issues and defects that LG either seems to deny or tend to not cover as "not typical use" or based on "viewing habits". I contacted Best Buy Magnolia support and they sent a tech out that confirmed my issues, and while there evidently LG provided him with a "service bulletin" procedure to perform that after completed would take up to 45 DAYS to address the issue. Both the tech and I found this to be utterly ridiculous so I addressed it with the Magnolia store manager. He advised that per the extended warranty terms they have up to 30 days to repair it otherwise they have to replace the unit or refund the value of the unit. Since the C7P has already been replaced with a C8 model a few months back the store manger agreed that after the 30 day attempt time period (we all know it is not just going to go away) he would refund me our original purchase price. The tech documented this in the service notes as we were all on speakerphone discussing the issue.
This was back on 7/28 and once I was able to confirm the Z9F was coming, Magnolia management allowed me to keep using the C7 until I get a replacement and put a preorder in for the Z9F. Considering we are not going to change our viewing and use habits to accommodate the OLED’s unfortunate technical shortcomings, I was pretty reluctant to go with a newer C8 LG OLED or any OLED for that matter as the likelihood of us running into the same issue is concerning even though the C8 SUPPOSEDLY has “better” resistance to burn-in and the other issues we have experienced with ours along with a better processor. One thing is for sure, they must be having more than expected issues with the OLEDs because the protection plans have gone up in price considerably since I bought last year.
I'm looking forward to getting the Z9F setup later so I can see it for myself because of all the "pros" already mentioned that are ideal for our viewing/use and sectional seating, and the "cons" seem like they will be either minor or irrelevant to us. Mind you, I'm not anywhere near the extreme enthusiast or professionals some are here regarding calibrations, measurements, terminology, and the like, but I do consider myself a "techie" person so I do understand and consider many of the more technical points of view and perspectives. This goes back to my agreement with mzupeman though. Sometimes all the technical and nitpick discussions can dissuade people from considering a TV that will be a homerun for their given use and circumstance so I take all opinions and even measured technical specs with a grain of salt. I will certainly try and provide my best impression from a not overly technical point of view on how happy I am with it by probably sometime tomorrow to get some time with the TV first with a variety of content. I will be running the TV connected to a Denon 3400H which has eARC support and using an Oppo UPD-203 player for 4K and other disc content.
