Hello,
I have a LG C4 OLED 77 inch TV and my GeForce NOW Premium subscription allows up to 2K resolution and I can set 2K on my Android and Windows devices but I can't set it on the TV which allows only 1080p (or 4K for ultimate subscription which I don't have). It would be nice to have that option because it greatly improves the image quality.
Best regards,
wido

Issue
Whenever I start any video—whether it’s streaming apps, HDMI input, or a USB movie—the SC9S plays for a minute or two, then suddenly loses connection. Audio instantly falls back to the TV’s internal speakers, and the TV acts like the soundbar no longer exists on the eARC port. The soundbar display still shows “eARC” (sometimes flips to “OPT/ARC” for a second), but no sound.
Temporary Fix
The only thing that gets audio back is power-cycling the TV (standby isn’t enough; full reboot required). After that, the bar reconnects… until the next random dropout. This can happen multiple times during a single movie, which is a great way to kill the vibe.
What I’ve Tried
New HDMI 2.1-certified cable (same result, so original cable seems fine).
Disabled Quick Start+ and Simplink in the TV settings, then re-enabled.
Factory-reset both TV and soundbar.
Tested ARC instead of eARC—works, but no Atmos and same occasional dropout.
Plugged the soundbar into a different power outlet (in case of power spike).
Observed Patterns
Dropouts happen sooner with Dolby Atmos or DTS content, but even stereo YouTube videos eventually cut out.
No obvious heat buildup; bar is in open air, front facing.
Happens whether soundbar is wall-mounted or on its stand.
Questions for the Hive Mind
Anyone else seeing eARC instability with the SC9S on the UP77 series?
Could this be a handshake timing bug on the TV’s HDMI board?
Any hidden service-menu tweaks or firmware betas worth trying?
Should I just RMA the bar, or is the TV the real diva here?
Appreciate any insight—my couch and I thank you in advance!

For native app developers, it would be great to see support for Vulkan graphics API. The requisite parts are already present, including the Mali GPU driver.
However, the Vulkan ICD file is corrupt on my my TV (webOS 24):
Here is the file:
{
"/bsppartICD"/bsppart: {
"/bsppartapi_version"/bsppart: "/bsppart1.3.216"/bsppart,
"/bsppartlibrary_path"/bsppart: "/bsppartlibmali.so"/bsppart
},
"/bsppartfile_format_version"/bsppart: "/bsppart1.0.0"/bsppart
}
It should be:
{
"ICD": {
"api_version": "1.3.216",
"library_path": "libmali.so"
},
"file_format_version": "1.0.0"
}
It would also need the Vulkan Wayland extension.
This would allow for some newer and better performant applications to run on webOS.
