Hi, I just purchased a M8500. Details in the Blu-ray player deal thread.
Here is my set up:
Set = Samsung Um65Ks8000
AVR Yamaha RX-V3800 (HDMI 1.3, no ARC) to set input 4
Roku Utra 4640 (2016) video Hdmi to set input 2, audio optical to AVR
2 Dish VIP722k DVRs Hdmi to AVR to Set
Samsung UBD-8500m video HDMI to set input 1, audio optical to AVR
All wired ethernet with consistent 70mbps internet download speed
Entire setup controlled with Harmony One remote
I hace CEC set to off on KS8000. My Harmony can set inputs, etc and I can't use ARC anyway.
I only run two speakers, so I will just set audio to PCM on the M8500. Speakers are Tyler Acoustics Taylo Reference Monitors.
I have slogged through this entire thread for info on settings. Here is what I found:
8500 set deep color off
8500 set color to 4:4:4
May need to force 1080 on 8500
KS8000 can have UHD color for input 1 set to on or off. If this is true, I will prefer off as ANY input set to UHD Color On causes havoc with my sound on various sources.
Let me know if I missed something
It looks like current FW is 1108.5
Thanks to Rudy1 for all of the inside info in this thread.
