Can i play 240hz on GamePC &stream 60hz to Streaming PC?

Postby daviddave1 » 11 Aug 2017, 09:30

i just got a 27inch Acer 1080P Predator XB272 240Hz and absolutely love it.

Now i still got some money left from my tax return. I am thinking about building a streaming PC to stream PC games.

Can i still play on 240 hz on my NVIDIA Gaming PC with DISPLAYPORT and stream to a Streaming PC through HDMI in 60 hz?

The (budget 2500K) Streaming PC will have some type of Capture Card? Is this possible?

All answers are much appreciated!

It's possible to do 240Hz out of HDMI 2.0 (I successfully did on one 240Hz monitor). So you may be able to mirror 240Hz on both DisplayPort and HDMI, yes.

However, I don't know if there's a capture card capable of doing 240Hz.

And even if there was, it would be the capture card's responsibility to decimate the 240Hz to the streaming frame rate (60fps) for things like twitch.

It's hard to come up with a workaround to output 240Hz via DisplayPort while output 60Hz on HDMI (3 skipped refresh cycles), but I imagine it's not impossible, but this would certainly be uncharted territory. Best research to start is to figure out what people are doing to stream 120Hz/144Hz -- graphics card streaming may actually be much easier in this case but would impact your performance.

Please post here, if you figure out the right workaround. Our readers would like to know!

Here's a video of a guy explaining with i hope is the answer on youtube. It's a little lengthy, but it should help

I got this link from a guy on reddit who also told me this:

There's a way to do it with OBS on your gaming computer using the full screen preview option built into OBS. Basically, instead of cloning your gaming monitor to your capture card (and thereby locking both displays to 60Hz), you keep the capture card separate. Do not clone your gaming display to it at all. It should be showing up as its own monitor in your Windows display settings if you have everything connected correctly. Then in OBS (which you'll have to install on your gaming computer), use the full screen preview option and send that preview to the capture card monitor. This will allow your gaming display to continue running at its native refresh rate while the capture card runs at its usual 60Hz.

Sounds like this is the solution.
