Hello everyone,

Recently i have started streaming and my main monitor is 2560x1440 pixels ..

I was thinking if i should downscale it throught one of the downscale options to 1920x1080p or is it better to set the canvas resolution to 1920x1080p and dont use downscale option from QHD to FHD, which option give better result?

Thanks for tips and have a nice day! :)

If you downscale, either use the output resolution in settings->Video or fit a larger source into a smaller canvas. Both have similar and good performance (negligible impact). Don't use rescaling within the encoder settings, this has significant performance impact.

What you should choose from the two former options depends on what other sources you might have, for example overlays. If your overlays and other assets are made for 1920x1080 resolution, use a canvas size of 1920x1080 to get no rescale for your assets (otherwise they are upscaled to 2560x1440 to fit a canvas of 2560x1440, then downscaled again to 1920x1080 for output). In general: try to avoid upscaling sources, especially if they are downscaled again in a later step.

Having said that, you might perhaps want to record your stream locally with the original resolution of 2560x1440, while streaming with 1920x1080. In this special case, you actually have to set your canvas and output size to 2560x1440 and downscale to 1920x1080 in the streaming encoder settings. But use encoder downscaling only for this special case.
