Surround troubles

[LoganBlocks3]

Hey All! Just a preface, my system is a ryzen 3 3300x, 32gb ram, 750watt power suply, and evga nvidia 670. I have 3 monitors, 1 (27" 1080p monitor), 1 (27" 1440p monitor), and 1 (34" ultrawide 1440p monitor). I know my GPU is absolutely underpowerd for this, so I plan on upgrading to an rx6600 soon, but for now, I have a couple questions. Does the 600 series have surround? On the surround page on the nvidia website, it says 700 series or newer, but the page for the 670 claims that it has surround. Additionally, If i turn down both 27" monitors to 1920x1080p and the 34" monitor to 2560x1080p, can I run surround? could I just make the game windowed mode and stretch it out, or is there a way to run full screen (perferred) Thanks!

 

Also, if I need to use 3 different cables, 1 dp for the ultrawide, an hdmi for the 1440p 27", and a dvi for the 1080p 27", would that work?

any thoughts?

For any kind of multimonitor setup, you HAVE to use AMD. Nvidia is complete nightmare even with similar monitors and resolutions, let alone with different displays. One of the requirements for NV surround is that the 3 displays (yes, it officially works only up to 3 displays) have to be the same resolution AND refresh rate. Now you can cheat your way around that by using DSR and reducing the faster display(s) to the refresh rate of the slowest one, but the time required to make that thing work is just insane. Personally when i was with my triple monitor setup and my TV on GTX 1070, it took me about 6 months to make it all FINALLY work... 70% of the time. The slightest signal disruption kills of the entire thing and you have to start over.

As for the performance - yes, using NV surround lifts up the performance (slightly) and boosts your FPS (slightly) compared to windowed mode and stretching the active window to fit all of the displays. It's really CPU dependent and 1% and 0.1% lows in games depend heavily on your CPU cause in the case of not enabling surround, it's the CPU which does the heavy lifting of synchronizing the image for all of the displays. In surround, the system treats all of the monitors as one giant display with combined resolution of all 3 of the displays + additional (virtual pixels) if you use bezel correction. 

 

With AMD everything is natively supported and as soon as you connect a new display, it instantly shows up and you can configure it however you like. It just doesn't give a f**k what display you connect and what resolution it is - everything just works.

 

As for the interface cables - in both cases it doesn't matter what cables you use. As mentioned in the Nvidia case you have to use monitors with the same resolution and refresh rate. The cables can be different.
