I have a document that when I open the PDF appears this in the visualization:

I want to appear like this:
How can I do this?
Thanks in advance!
EDIT:
I solved my problem. I will put the solution here in the case someone has the same problem.
I read the document 'READ.md' which came with the template for my thesis and there was written that the standard print of version of the PDF document was programmed to be 'twoside', then I would need change where was written 'print' by 'oneside' in the documentclass, i.e.,
\documentclass[a4paper,12pt,times,numbered,index, print]{Classes/PhDThesisPSnPDF}
by
\documentclass[a4paper,12pt,times,numbered,index, oneside]{Classes/PhDThesisPSnPDF}
\usepackage[pdfpagelayout=TwoPageRight]{hyperref}but probably it will be ignored by your viewer. A posteriori, most probably you could set a "Two Page view" option in the viewer menu or so, but anyway, depends on the viewer too. – Fran May 24 '20 at 00:03\usepackage[pdfpagelayout=SinglePage]{hyperref}instead. – Ivan May 24 '20 at 00:23\usepackage[pdfpagelayout=SinglePage]{hyperref}in your preamble and compile. If the file is displayed with two pages side by side, check options in your PDF viewer and/or try with another one. Or ask someone to check on his side. Sorry, my knowledge stops here. – Ivan May 24 '20 at 17:45
