Display Modes
Opera offers several display options that can be activated using Menu > Display
Zoom
Select Zoom to change the zoom of the current page. This option will scale images, text, and other page content.
Load images
For faster browsing and lower cost, you may choose to display only images that have already been cached locally by Opera. This setting is changed by selecting Load images from the Display menu.
Full-screen mode
Activate this mode to use the entire screen for browsing. The standard menu and title bars will not be shown in full-screen mode. To return to normal mode, use the soft keys that would normally activate the browser's menus.
Fit to screen
Opera's Small-Screen Rendering (SSR) technology reformats Web pages intended for desktop browsing to fit the screen of your device. This mode is on by default, and is activated by selecting Fit to screen from the Display menu. If you select Desktop from the Display menu, Opera will show Web pages without changing their layout.
Single column
On high-resolution screens, pages may become hard to read in portrait mode. Selecting Menu > Display > Single column forces a simpler rendering mode that normally will increase readability.
