Capture resolution

[HSMtrue]

Hi all,
First of all, sorry for my english))))

I have a question about capture resolution.

What will be better in streaming with 2560x1440p monitor.

1. Base(canvas) resolution (1920x1080) + Output(scaled) resoulition (1664x936)
or
2. Base(canvas) resolution (2560x1440 my native monitor resolution) + Output(scaled) resoulition (1664x936)


It is a big question, because i don't know how works screen capture for real.


Thanks for your attention and answers))

Make it so that you have the least amount of rescales, so it's choice 2.

Thank u, but no visual differens

Downscaling will always come with a quality loss. Especially when you are using a non-full-integer downscale, and a weird final output resolution for whatever reason on top of that.
For the 'cleanest' downscale, you'd want to go from 1440p to 720p, which is a 2:1 full-integer downscale. Every block of 4 pixels becomes 1 pixel in the output.
For absolute BEST quality, you need to play at the resolution you'll be streaming at, and keep everything native.

This is one reason 4K monitors are the best choice for livestreamers at the moment; they offer a 3:1 downscale to 720p, AND a 2:1 downscale to 1080p. They can also cleanly run at the lower resolutions while streaming (with sharp 1:2 and 1:3 upscales inside the panel), and bump up to full-res when not streaming.
1440p needs to be kicked in a hole, set on fire, buried, and forgotten about forever. Like 1050p and 1200p have been. I hate it almost as much as the legacy 59.94 and 29.97 framerate idiocy.

Love the passion. and succinct explanations

However, in the food for thought category, in my case, 1440p comes in very handy as I record Windows Capture at 1080p, so I needed a monitor that is 1200p or higher, so Windows application Window title and status bars can be cropped leaving native 1080 pixel tall window in OBS, with no scaling required [in my case, a Portrait Mode windowed {not full screen} PowerPoint slide show alongside a 1080p NDI PTZ video feed]
