Since you have the monitor connected, why not just try it? BTW, as you want to map 16x10 onto 16x9, and want to keep the pixel aspect ratio, the black bars will be above and below, not left and right (i.e. you'll be reducing the height, not the width). As I think I mentioned, I use the built-in Display Settings on KDE for adjusting this kind of thing. I assume that whatever desktop you use has something similar. poc -- _______________________________________________ users mailing list -- [email protected] To unsubscribe send an email to [email protected] Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/[email protected] Do not reply to spam, report it: https://forge.fedoraproject.org/infra/tickets/issues/new
