With this settings NV Enabled, sometimes i can see the 7680x1440 option in the Surropund menu, but when i enale Surround the center monitor goes black.

Here are my monitor settings.

Also have tryed to change UH frequency to 59.950 to match others, no sucess.

The monitor needs to support 2560x1440 without GPU scaling. NVIDIA Surround will not use GPU scaling. Which monitor is the center monitor? If it's the Acer X34, that seems to be a G-SYNC monitor, and monitors with the G-SYNC module only support a very limited set of resolutions. NVIDIA Surround requires all monitors to support the same resolution and timing parameters.

Got it, so no way i can make this work in 3x 2560x1440 Sad

Why a 3440x1440 just dont support 2560x1440... crap!

A manage 5760x1080p, very unstable, when reboot PC dosnt work, need to readjust something until it works again.

Hello. This might sound bizarre, but on one of my PCs I've been having a minor issue with restarting the graphics driver via CRU. The graphics driver itself will restart as expected, but restarting this way has the side-effect of the connected speakers disappearing from the Windows sound device list. No matter what I have to reboot the computer to get the speakers to re-appear and work again. Any ideas?

What are the speakers connected to? Does Device Manager show any disabled sound devices when this happens?

Usually they do but monitors with the G-SYNC module don't have a complete scaler.

Unfortunately, NVIDIA's driver has a bug that can cause Windows to hang during boot when an EDID override is present with multiple displays connected. I'm not sure what the trigger is because it doesn't always happen, but it might be related to G-SYNC being enabled. This is something NVIDIA needs to fix, but this bug has been around for years now.

The speakers are connected to line-out. In Device Manager after the graphics driver restart, the entry for the speakers just vanishes rather than showing as disabled.

Line out of what, the motherboard? What is the name of the device that vanishes?

Yes, the motherboard. The name is something like "Speakers (High Definition Audio Device)".

That's "Audio inputs and outputs." Look under "Sound, video and game controllers." Does anything get disabled or disappear from there?
