Did you see this story? Ouch! https://www.hardocp.com/news/2018/07/08/lg_embarrasses_oled_burnin_at_sid_tradeshow Edit: I just invested a bit of time at rtings.com. The OLEDs are impressive, and it looks possible that the manufacturers have a bead on the right techniques to mitigate the possibility of burn-in under worst case circumstances. Using a fixed desktop and taskbar, and a browser with visible tabs and Menu bar is what gave me cause for concern. I have a 43" XBR X800D from 2016 and it's working out really well, but the year 2018 is showing signs that its eventual replacement might be a solid upgrade. Though it's a bit disconcerting to not see the most advanced features being offered in smaller size panels. I was hesitant to go with a 43" inch set for my desk as it seemed to be too much of a good thing. It's worked out, but I do feel I'm at about as large a size as I can accommodate. Maybe when variable refresh rate becomes common, then we'll see the manufacturers wanting to pursue PC users who want more than just a monitor. I guess I'll know when the 2019 models get teased if my checklist of features will get met at the 43" size.
