3D models render small when increasing render resolution

[NeoCortex]

I am using the latest version of Octane render 3 standalone but I cannot get any scene to render the same size as the viewport when I increase the dimensions of the render I can get a render of the exact scene size in the render viewport when I use the default low resolution but when I increase the resolution dimensions to something like 4k dimensions the final render looks zoomed out. I tried clicking the icon that fits the resolution viewport but that only works at the default resolution as soon as in increase the canvas size the final render has small zoomed out objects I am having this problem with all of my 3D models because I don't know what settings allow me to fix this. Can anyone help?

Hi NeoCortex,
if the rendering resolution is grater than the monitor resolution, you should see a couple of bars in the viewport borders to navigate the render buffer:

You can also use crl+LMB for navigate the frame.
