For some reason the Split Screen Horizontally shortcut isn’t working. Instead, it zooms the screen. (In trying to fix this I’ve set the screen resolution at something horrid, and can’t get it right again.)
I can split the screen by going to View/Layout/Split Screen Horizontally - but trying to do it by way of the cmd-alt-= shortcut instead zooms the screen in hugely.
In your System Preferences, load the Universal Access panel and disable keyboard screen zooming in the vision section. You can also do this by just pressing Cmd-Opt-8, most likely.
I suppose you don’t know how to get my display back to something that doesn’t either have black lines on either side of the screen or look bizarrely stretched-out, by any chance?
Taking a guess at your problem, you might be able to fix it in the Displays section of Sys Prefs. There should be a bunch of screen resolution options, and you should pick the very bottom one on the list; that is the one your screen has been designed to run at. Otherwise, I’m not sure what could cause the screen to be the way you are describing.
Ah, thank you, that’s much better - and it’s handy to know that the one at the bottom of the list is the one designed for my system.
Everything is a little teenshy for my shortsighted eyes at this resolution, but there’s probably a solution for that. Maybe I just need not to work on a laptop any more.
You can certainly use the other ones on the list, it won’t hurt anything, and most of them will not be stretched or have black bars. The only drawback is that things will be a less crisp, but if the “native resolution” is too difficult to read, that’s a small price to pay.
