Correct, in the 5K case the entire display is rendered at 5K, and ditto 2K etc. (I believe the internal canvas caps at 32K, but I don’t have the tools to find out for sure.)

Whatever-sized display viewports are just crop windows into it, and the crop window in internal canvas terms is scaled as necessary, and then it renders the vector canvas onto the raster viewport.
