Question / Help Would this dual-pc streaming/recording setup work?

[Razacx]

Hello,

I'm trying to figure out if this diagram I have made would work:

The splitter cable I'm referring to can be found here:
http://www.allekabels.nl/dvi-kabel/...ovjklQAU3TKuYSnyZmkbkl1wFoyUgiP5NIaAgDf8P8HAQ

The page is in Dutch so I'll explain a little bit. The cable takes a DVI-D signal and splits it into a HDMI female and DVI-D female port.

The reason that I'm trying to do this is because I'm used to playing with very high framerates on my main monitor (144hz display). For some reason, even small fps drops caused by OBS are really annoying in games (and in games like osu!, break concentration). Using this setup, I am hoping I can offload OBS's system load to another PC.

My main concern is this though: Does anybody know if the DVI-D output (after splitting) on the cable will still support a 144hz display? I just don't want to go out and spend money on cables and a capture card if it won't work :p

Thanks in advance

PS: My apologies if this thread was posted in the wrong section.

It's better to clone your display and use a 2nd output from your PC to your capture card than using splitters. I'm not sure whether cloning requires the capture card to also be able to support 144 Hz or not though.

It does indeed require both displays to have the same refresh rate. And since I don't have two 144hz displays, that's not an option :/

Or just run the display at a refresh rate your capture device can handle, while streaming.

That's a problem though. There are some games that I absolutely can't play on lower framerates (like osu!).

The bigger problem you have is probably to share the sound

Sound is not a problem. I use normal audio jacks, so I can split it of my main desktop and then use the microphone-in on my second system for getting the sound in the recordings.

I'm sure there are many who play Osu! at 60fps just fine. "Absolutely can't'" is far from absolute, this more falls into the 'don't want to' category.

That out of the way, clone your gaming display to a spare port on your GPU. I believe some nVidia cards can run cloned displays on different output ports at different refresh rates.

Well yes, you can play it on 60fps. But a 144hz refresh rate offers big advantages in faster beatmaps (and that's not just my opinion).
Also, it would just be quite stupid to have a 144hz display and not being able to use it.

I've tried cloning the display already, but the refresh rates for both displays get set to 60hz. I'm using an AMD card (hd7970) and I can't really find any similar options to the thing you described in the amd control panel.

Still, I'd like to know if my idea with the splitter cable would work? I can't find any information on it anywhere...

Welcome to the same complaint that people who have bought 4K monitors have, when they end up trying to downscale to a reasonable streaming resolution. It comes down to 'too bad, deal with it'. Enjoy the 144hz when you're not streaming, deal with 60hz while live.

No, splitter cables don't allow running different outputs at different refresh rates, and lock both to the lowest common rate. You might be able to find an HDMI matrix with internal re-encoding, but that will induce extra latency and make the 144hz pointless as you'll have relatively massive amounts of lag due to the digital processing/transcoding delay.
Yeah, AMD cards don't as far as I know allow separate sync rates on cloned displays.
