They should work anyway but if you want to view the whole page you can zoom the pages to a size that works better for you. Or you can resize the resolution of your desktop.
I think all current browsers have this zoom feature-all of mine do. If yours doesn't you probably just need to update to a newer version.
To zoom the page to your desired size just go to your toolbar at the top of your browser-select view-select zoom and set the size you like.
