I’ve joined the forum just for this thread and i really hope that someone of you can help me.
@cecemf i’ve got an LG G1 OLED Evo connected to the hue sync box.
Into the 2nd HDMI port of the hue sync box i’ve got an Amazon Fire Cube, and into the 4th port i’ve got a PS5.
Directly to the TV (into the eArc port) HDMI 4 port, i’ve got a sonos arc soundbar.
Each device is connected through Ivanky certified HDMI cables (Amazon product) and they’re working great.
Suddenly the dolby vision issue is still present for me, every time i have to enable the “enhanced dolby vision” that downgrades the picture quality to a standard HDR (i suppose) but the light sync works well, without that option enabled the lights won’t sync.
With fire cube connected to the hue box my LG G1 displays the video output as rgb 8b tm - 3840x2160p - 60hz fixed, the colors are amazing and dolby vision works correctly, but lights won’t sync.
if i enable the enhanced compatibility in hue sync, the video output is YCBCR422 8b, the colors seems washed out and less brighter and of course, light sync works well.
If i connect the fire cube directly to the tv the video output is rgb 8b tm - 3840x2160p - 60hz fixed (same as hue sync box without the dolby option enabled).
With PS5 all is working but i think it’s only because PS5 doesn’t support dolby vision…the only thing i can’t understand is that if i connect the ps5 directly to the tv the output is rgb 12b 4l8, but if i connect it to the sync box it will be YCBCR422 8b (like the fire cube with the enhanced dolby enabled).
I don’t think that my hdmi cables are the problem, but in case…what hdmi cable should i try?
Sorry if my english is not so good, but i’m italian
Ps: all of my devices are updated to the latest firmware version.
Hope that someone of you can help me, thank you!
I have a similar setup and got none of this issue, would suggest reporting the HDMI sync as faulty and getting a replacement. for me, all plugged in and Dolby setting on on HDMI box and has no issue whatsoever! Side note you should have the PS5 via HDMI sync but directly to the TV. as HDMI Sync box doesn't support 4k 120Hz, so your PS5 game will suffer.
