You don’t say how large your laptop screen is, but if it’s in the range of 13”–15” as most laptop screens are, a resolution of 1920x1080 will make things look tiny. I think your best option if you are going to use it with SONAR is to buy a larger monitor and connect it to the laptop. I would say that the minimum for that resolution is 24” (unless you're very young).
Seeing that this is your first post since 2015 I assume that you don’t visit this forum very often. You seem to have missed that Cakewalk has been abandoned by its previous owner Gibson and that all intellectual properties have been sold to a company called BandLab. Read more here:

In short: the good news is that you can download and install a brand new DAW called Cakewalk by BandLab for free, which is basically an updated version of Cakewalk SONAR 2017.10. Updates are distributed regularly.
