Nvidia Surround Not Working

https://nvidia.custhelp.com/app/answers/detail/a_id/5338/~/using-high-resolution%2Frefresh-rate-displays-with-vesa-display-stream Unfortunately; you're going to "have to" disable DSC if you wish to continue using that 30-series GPU + displays + Surround bud.

Am I nuts, or does that article not mention Nvidia Surround at all? I don't see anything suggesting that it shouldn't work.

Bump - issue remains unresolved

. I do not know but here are 2 things to try. Set both monitors to 60Hz. Put then In Surround at that Refresh. Then you should be able to get DSC working as long as you are at that refresh. Here is my theory.... DSC = 2 Headers and the card has 4 total. So (2) Monitors in DSC = (4)headers in use. But 240Hz = (4)4K@ 60hz So, by dropping the Refresh to 60hz there should be ample bandwidth to operate the monitor. If it works, then start bumping the Refresh by 30Hz to find where it does not. Second item to try.... Create a Custom Resolution of 3840x4320 (thats (2)3840x2160(fake 4K), not (2)4096x2160(real 4K)) using the NVCP and then try again with toasyX CRU Once you put the monitors into Surround, apply the Custom Resolution to it. .

. No on the 2x Monitor Resolution. ==================== See what CRU says when you install this driver for TESTING: Disable the automatic Driver updating: https://www.minitool.com/news/disable-automatic-driver-updates-win-10-009.html Use all 3 methods if they can be used.

. It was my understanding the DSC increases the bandwidth of the DP 1.4 from 32.4GB/s to closer to 48.2GB/s via its compression. Since the 32.4 should be enough for the 4K UHD @ 120Hz, this would allow SOURROUND with (2)4K monitors @ 120Hz PLUS. But, Nevermind, Obviously Im an idiot. .

I have an RTX 3090 and two MSI MPG 321URXs, and I have yet to successfully enable Nvidia Surround without disabling DSC in the monitors' settings. To be clear, the 3090 has no issue driving both of these monitors simultaneously at 4K/240Hz/HDR (with DSC enabled on both monitors, of course), but enabling Nvidia Surround with these settings causes both screens to go black, even between restarts. The only way I've discovered to regain any video output is to disconnect one monitor while the computer is powered off to "force" the graphics card out of Surround mode. (This doesn't always work; it consistently takes me ~3 blind restarts as of late, alternating which monitor is connected each time.) If I turn DSC off on both monitors, Nvidia Surround as well as the monitors themselves are limited to 120Hz, but it otherwise seems to work just fine. I can't imagine there's truly no way to get this setup working at 240Hz, so... does anyone have any suggestions? Also, since I know I'm going to get this question: no, I do not have any other monitors plugged in.
