Hello,

I have the G9 OLED for two days and have really lousy problems:

- when I start a game in fullscreen mode with the native resolution of 5120x1440, the monitor sometimes shuts down. There's no way to restore the image until I'm somehow able to either blindly quit the game or restart the PC - sometimes only the reset button helps.

- When starting certain apps or fullscreen applications, I hear a sound like a device is connecting and disconnecting. I also hear this randomly - it stopped, when I disconnected the USB cable from the monitor and ramains happening when I start full screen applications and exit them.

- I randomly have black screens every now and then without doing anything specific. And quite extreme: If I watch a video via any media player, enter fullscreen and move the mouse, the screen goes black for 3 seconds and then returns. If I move the mouse again, the screen goes black again. This goes on and on.

- I am using an RTX 4090 with this monitor. When I set it to 240 Hz, the GPU memory clock rate is not downclocked when the PC is idle. That means the GPU memory clock (not GPU clock) is always running at max clock, which is not ideal for power consumption and temperatures.

I use a Display Port 1.4 cable with 32.4 Gbit/s, but also have an HDMI 2.1 cable with 48 gbit/s. This happens with both cables. As soon as I lower the monitor Hz to 120, the memory MHz goes back to the correct idle value, as it should. Is this a normal behavior?

- when I turn off VRR on the monitor, it is no longer possible to set the native resolution.

The monitor is running on the latest firmware version 1023.

These are honestly such massive problems that I am almost determined to return this monitor to Samsung as soon as possible.

Any input from more experienced Samsung users who have been able to remedy these issues?

Thanks so much!
