When I scale from 2560X1440p144 to 1920X1080p60, I receive “Resolution Not Supported for Resizing” message in the preview screen of OBS Studio. What can I do to fix this?

GC553 doesn't have a feature for resizing 1440p to 1080p resolution.

If you change the resolution to 2560X1440, you will be able to receive the signal from the input source.

However if you still want to rescale output for streaming or recording, please adjust the rescale output by following below illustration:

You can go into File > Settings.

Enter the Output tab, click on the Output Mode to set Advanced, then configure the rescale output of your stream or recording to 1920x1080.
