21:9 Capture Card Issue

[ncrossy1980]

Hey guys,

 

Just wondering if anyone has any suggestions here.  I have a 21:9 3440x1440 LG Ultrawide, and when I record 1080p video and live stream, I use XSplit to capture the upper left corner in a perfect 1920x1080 area where I manually dock my applications in there that I want visible during recording.  As shown in the attached image.  The real estate outside that region is my personal space whilst streaming, it's really nice to have that.

Due to the heavy nature of what I do, some application operations pull the CPU so tightly (4790K @ 4.6) that it leaves Xsplit gasping for air, and I drop thousands of frames at a time whilst live streaming.  

So I bought a Elgato HD60 Pro capture card, stuck it into a secondary PC, hooked up the HDMI, mirrored the main monitor with the HDMI output and boosh I've got an unsupported 3440x1440 signal going into my capture PC.  My plan was to then use Xsplit on the capture PC to crop the 3440x1440 signal to the 1080p region, and broadcast that, but I guess due to the shift in resolution on a received signal, the image degrades to the point that it's totally unusable.

So I'm just wondering, does anyone have any advice (if its even possible) to successfully use a 21:9 panel with a secondary capture PC without resorting to nerfing my 3440x1440 panel to 1920x1080? I cannot find a single thread anywhere discussing this issue, which is surprising given the increase in popularity of 21:9!

Thanks in advance.

i think your best bet will be getting a card that can handle stupidly big res (there's cards out there limited to something just past 4000 pixels in both horizontal and vertical) and then crop to size in xsplit.

Ahhh yea I read about them, but every article I read (possibly not reputable sources) advised against these 4K capture cards.  Bummer, but OK and thanks very much for the suggestion.

Sorry to bring this old thread back to life, but did you ever work out how to do it as I'm now having the same issue using 2 pc's and an Elgato HD60 pro on my 21:9 3440x1440 ?
