I received my 77C9 Saturday morning and spent most of the day playing with my new toy
I was able to get LPCM passed through to my Denon 4400 via the SHARC eARCH appliance after some initial frustration. It turns out the default HDMI capable that came with the device can not pass lossless audio and once I switched it out with a certified HDMI2.0 capable, I was able to get lossless audio working.
I've left Windows set to output Dolby Atmos for Home Theater. I get LPCM for games that don't support Atmos and Atmos/TrueHD from games that do. Everything sounds great and no lip-sync issues! I also tested the internal LG apps and audio sounds works well there too.
Thanks to everyone for the tip on that device! It saved me the need to upgrade my AVR.
The only oddness I've seen is that sometimes when I switch inputs and come back to my PC, I get some overscan with the picture and the taskbar gets partially cut-off. If I re-run the restart64.exe from the CRU tool, it corrects the issue. Has anyone else seen this?
My RTX card is set to arrive on Wednesday so for now I'm using my 1080Ti which means I can't take advantage of G-sync yet. I have to say though that gaming at 1440p 120hz is a revelation! I played a good amount of Shadow of Tomb Raider and RE3 yesterday and both ran beautifully!
Is it recommended to leave Windows in HDR mode on the desktop or does it increase risk of burn-in? I was actually impressed with the overall look of the desktop in HDR. With my old Sony LCD, the text would look very blurry and washed-out in HDR mode, but I don't see those issues with the C9.
I've taken some of the common steps to reduce burn-in risk by enabling auto-hide on taskbar, removing desktop icons and switching background color to black. Any other tips I should be aware off?
Also watched Lego Movie 2 UHD with my son on my new UB820 media player and he was also suitably impressed
