Question / Help Game Capture card + 21:9 Monitor, streaming output?

[Tenzai]

So yea, I'm thinking about getting a 21:9 ultrawide screen monitor and wanted to still stream in 16:9 full hd res.
Is that even possible gaming normally on my 21:9 and still output a 16:9 stream?
Right now I got a 16:9 monitor parallel to the game capture card (means that it doesn't even record the actual screen but instead the gpu gives out another monitor output and I simply mirror my 16:9 monitor to my game capture card).
What happens if I change my 16:9 monitor to a 21:9 monitor and mirror the image to my game capture card?
Can someone help me out? Thx in advance

Either way works but you will have to live with black borders either on your side or the viewers side.
You can configure any output resolution you want in OBS.

what about streaming with the elgato game capture card? Does it support 2560x1080?

edit: nope it doesn't :/

Does any streamer with a 21:9 monitor can tell me how they have everything set up for the stream? Would be great, thx

Tenzai, I have managed to set up a 21:9 / 3440x1440 stream myself. I will post a short explanation here, reply to this thread if you need more info. I've chosen a two pc set-up (without capture card) to keep the load on the gaming system in check. This is however not necessary. In order to get the two pc setup to work I have only bought the following items:

- 2x additional network card
- 1x UTP cable (straight or crossed, doesn't really matter anymore)

Gaming PC:
- Running game in 3440x1440
- Running OBS1 but only capturing a 16:9 center portion of the screen in 2560x1440 (all essential things happen in this region. But you could choose to capture the full 21:9). OBS1 then outputs this in 1920x1080 @ 30 fps on a dedicated, second network card over ethernet directly to a second PC. This 'first' stream is set to 20000 kb/s using the integrated intel graphics processor of the CPU. So it is very light on the gaming pc's resources.

Streaming PC:
- Running NginX with RTMP under windows to 'capture' the stream from the gaming PC.
- OBS2 capturing the RTMP stream from NginX.
- OBS2 adding overlay, twitch alert plugins etc. etc.
- OBS2 outputting at 720p @ 30 fps to twitch on yet again a dedicated network card.

Alternative:
If you want to stream the full 21:9 image, you can do so. In that case I prefer to have OBS still output a 16:9 image with black bars on the top and bottom. You can choose to fill those with some extra information for your viewers, such as followers/donators/CPU/RAM/GPU load etc.

Final remark: I have just started streaming and this is my solution for a 21:9 monitor. There might be waaay better solutions out there, this is simply the one that worked for me.

Hope this helps! Any further questions? Let me know!

P.S. You can check the result on twitch.tv/majorglory78 it looks like any 720p/16:9 stream but now you know I am seeing a bit more when gaming :)
