Question Samsung 49 inch Odyssey 0.03 ms 240 Hz OLED G9 Gaming Monitor (LS49CG932SNXZA) ?

[Cybrex]

Hello everyone,

Hope someone can help me figure out to issues I've been having since I bought this monitor last summer.

1) I cannot remove the speakers of this monitor from my system. I've disabled it, set my soundbar as the default, I've checked the settings on the monitor itself and can only turn the volume down but no matter what I do, when I use the PBP option on the monitor (work laptop one side, personal pc on the other) the system automatically switches over to the monitor speakers and then I have to switch it back. This happens every time when I turn on/off PBP.

2) Random screen flicker. What I mean by this I could be just sitting here either watching or working on something or gaming and the screen will out of nowhere turn black for a few seconds and then come back to the screen. Top left hand corner it'll also display, HDMI. Its completely random and there days where it never happens and other days where it happens 5 times throughout the day.

Hello everyone,

Hello.
1. Open sound settings and remove all devices which you do not intend to use.
2. Get an HDMI cable rated for 48Gbps or ultimately use DisplayPort instead.

Cable seems to be working. Haven't witnessed any flickering since.

Unfortunately I've deleted all the devices I don't intend on using but when I turn off PBP the monitors speakers return to an option for use.

If you haven't tried it this way..
Go to Settings > System > Sound, Select "All Sound Devices", beneath the Advanced section.

Then select the device which you do not want Windows to use and then click "Don't Allow".

Unfortunately I have tried this before as well and somehow those damn speakers force themselves back into my life.

@Cybrex

Did you install any drivers (or any software at all for that matter) regarding the Samsung 49 Odessey monitor?

Are you using any power savers or screensavers on either desktop and/or laptop?

= = =

On both desktop and laptop:

Use Device Manager: Check all of the audio and display device drivers - especially their Events tab via Right click > Properties. The event entries include timestamps. Are there any timestamps that correspond with the times of switchovers?

Look in Task Manager, Task Manager > Startup, Resource Monitor, Task Scheduler, and Process Explorer (Microsoft, free).

https://learn.microsoft.com/en-us/sysinternals/downloads/process-explorer

Some process might have started when the switchover occurred. Or conversely - stopped.

= = = =

Use all of the tools but only one tool at a time.

The objective being to look for some app, utility, or process that is running in the background beginning at boot up.

Or possibly something later being triggered to run via Task Scheduler.

You can also look in Reliability History/Monitor and Event Viewer.

Either one or both tools may be capturing some error code, warning, or a simple informational event at the time the speaker switchovers.

The way I would go about it is to setup desktop and laptop. Look at, for example, Device Manager > Startup on the desktop and on the laptop as well.

Look in Task Scheduler on both, etc. etc.

No need to rush - take your time and print out screenshots for reference purposes if and as necessary.

Good news is that you can force the matter by turning PBP on or off. You have control there.

Focus on first finding some change that occurs just before or at the time of the switchovers. Or being captured after you change PBP.

Once a possible reason or cause is found then the next step is to stop or fix it.

All the above may seem like a lot of work - not really and once you get a sense of it all (if necessary) then it does become easier.
