This is for all that have LG monitors with the latest software that changed UI settings for GAME OPTIMIZER
I could not find this anywhere on the internet for an update on what happened to the compatibility modes for DisplayPort/HDMI. Everything is outdated.
Apparently LG updated their UI and MOVED the option for compatibility modes to disable DSC. This USED to be in the common GENERAL tab, but NO LG moved it to the External Devices, which makes no sense as it should be with the common general menu.
I'm not sure if this is a bug or an oversight, but here it is
SETTINGS BUTTON > GENERAL > EXTERNAL DEVICES > INPUT COMPATIBILITY
Why would you disable DSC, you ask?
Well, if you don't disable this mode, you will not be able to use scaling factors like DSR on NVIDIA. I have seen remarks about AMD being able to use it without this option turned off, but for NVIDIA they are behind on this.
This WILL disable high frame rates beyond 144 Hz for the trade-off, but you will be able to scale your resolution higher.

I have been using led strip in the back of the LG C4 tv, I lugged into the TV usb port. Usually the turn on when the TV turns on, and turn off when the TV is turned off. Starting today, the led strip stays on after the TV is turned off, meaning the USB port must be remaining active. I have checked and tried every setting I can see in the TV settings but nothing changes. How to make the usb ports turn off when the tv is turned off?

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!

Question
NikD63
I just got an OLED55C8. I won't have a cable or antenna connection to it, nor will I have any other devices physically connected to it. So there are no input sources to choose from. Everything I view will be coming through WiFi.
Whenever I turn on the TV, it comes on with the TV source selected. And because I have no signal sources connected to it I get a random noise picture and sound. If the volume was up high on the previous viewing, the random noise is pretty loud. It can be pretty jarring at times.
Is there some way I can set it so that upon power-up one of my streaming apps, such as YouTube TV or Netflix, is selected? Or can it come on with the volume off and on the home screen? If not, is there some way I can at least set the default volume level used at power on?
