Resolution the 1920X1080 whit Problem. Zorin OS 17.1 no recognize ! Help !!! 
Hi and welcome to the forum.
Is this a new install of ZorinOS 17.1, or installed alongside Windows or another OS?
Can you tell us which edition of ZorinOS you have installed (e.g. Pro, Core, Lite etc)?
Also please edit your forum profile, to indicate that "edition" information there, as that will help us help you in the future.
Have you checked and can tell us which driver you currently have for your Nvidia graphics?
I don't have Nvidia myself, but that information will be good for a forum member that can maybe help solve your resolution issue.
EDIT: I have just searched the forum and found this re Nvidia GT 610, which may give some clues: No display after select zorin os from grub
