Bought an LG CX OLED a month ago. loving it - except how it interacts with my Hr24 that is connected to my AVR - it just does not see it. Been fighting with D to get a 54, they hold on to them as if they were gold. Right now I have 7 DVRs - 2 HR20s and the rest HR24s, been with D for 19 years, no contract. I'm wondering if the HR54 has better CEC functionality and it's worth the effort to get. The CX sees everything connected to my Marantz 7010 and allows switching with the remote. I'm trying to limit the number of remotes, I do have a Harmony but the LG remote functions better with the TV than the Harmony for me. I installed a SWM21 reverse LNB but do not see any reason to add 4K service that is so limited. I do all my own installs, my experiance with D installers is poor and will never let them set foot in my home especially now. I'm looking at the used market, lots of HR54s on ebay and even Amazon. I am well acquainted with the issues off buying on ebay, all but one of my DVRs are owned, bought off ebay with clean numbers. Spend a lot of time with D in the past checking receiver numbers. D offered me a HR54 for $199 but seems a bit steep, willing to go $99 but they wont budge. Will the 54 function better in my setup or is it a wash?
