LG OLEDS give a fantastic picture. No current technology has blacker blacks. Great contrast and more than adequate brightness for me. Mine is a 2017 model and hopefully they have been able to make it less susceptible to burn-in. Mrs Volts is a new junkie and there are there are several spots of burn-in. I understand how the bug in the bottom right corner did it, I'm less happy about being able to make out where the news scroll at the bottom of the screen was, and I'm upset that there is a silhouette of a talking head. In general viewing none of these is really annoying but they are there.
So what will I buy for my next TV, probably another OLED - they just look so much better. It will probably be another LG even though I'm PO'd with them due to problems with my car's battery pack and the recall that will take forever to complete.
