Question / Help Dual PC - convert 1440p60 to 1080p60 on capture PC?

[Nezakhan]

Hi! I was curious if it's possible to convert a 1440p60 (w/g-sync) signal from one PC to 1080p60 on a second capture PC. (not streaming)

I have two cases ordered, and my plan seems to keep changing, but I had hoped to be able to game on an Asus PG279Q 27" IPS 16:9 1440p 144Hz (gsync) display, with the signal sent to a splitter and then to display and capture PC.

Both systems are Win10-64. Please advise.

1440p is not recommended.
Gsync does not play well with others, as a proprietary tech from a somewhat open-source-dismissive company. It tends to cause tearing, especially when used with capture cards or OBS; most streamers have to turn it off and go back to vsync instead.
You'll also need a capture card capable of capturing 1440p, which aren't cheap.

See if your GPU can send mirrored displays at different resolutions (some nVidia cards can do this, but not all). Grab an SC512 (1080p@60 cap card) and send it 1080@60 signal.

Also be aware that if you're planning to stream to Twitch, 1080p@60 is significantly above the bitrate range that non-partners are advised not to exceed (2000kbps), and are significantly above the rated ingest maximums as well (3500). 1080@60 starts around the 6000kbps range.
It won't matter what you're putting out, if no one can watch it; and a majority will not be able to watch at even 3500, much less 6mbps.

Thank you FerretBomb.

My situation is a little complex, and a little simple. Skipping past explanations, I'd love to be capable of streaming, but for my project I have no intentions of streaming. I merely wish to capture and edit. GPU's capable of sending mirrored displays at different resolutions? This is the first time I've heard of this (and I'm falling over in excitement considering how hopeless I've felt up until now)

Thank you!

As noted above, for my project streaming is not required.

This perhaps best describes my intention.

EDIT: I believe the question has been answered. So I think I need to find out about a capture card for the above layout and exclude the gsync issue. Being able to turn gsync off makes it not really a problem with getting this layout to work, which was my initial concern. I'll repost anew and ask regarding the capture card for the layout itself.
