<![CDATA[[FAQ] How do I add a command line switch to Opera]]>Sometimes it's necessary or helpful to start Opera with a command line parameter.
This is how you do it (Windows):

  1. right-click the shortcut you normally start Opera with
    (1b right-click the Opera beta/developer entry if your shortcut is sitting at the taskbar)
  2. choose "Properties"
  3. In the Target-field add --name_of_the_switch=its_value behind the last "

You can have a look at Chromium's command line switches. A lot of them will work in Opera, too. 😉

What is the name of the switch for dpi adjustment?

I think you are looking for this

Good news folks. We have fixed running with custom DPI settings.

Basically to run Opera with custom DPI use --alt-high-dpi-setting parameter. For example:

100%: opera.exe --alt-high-dpi-setting=96
125%: opera.exe --alt-high-dpi-setting=120
150%: opera.exe --alt-high-dpi-setting=144
200%: opera.exe --alt-high-dpi-setting=192
250%: opera.exe --alt-high-dpi-setting=240
