How to fit screen on my external monitor

[Drifty_Child]

On my external monitor, this is all I can see. The menu bar and half the dock is cut out. Doesn't matter whether I use it as a mirrored screen or separate screen. How do I make the whole thing visible from top to bottom on my external monitor? (It's an old 1080 x 1920 TV)

If it is an older TV, Overscan might be enabled. Overscan will slightly enlarge the picture, to make sure all the pixels are in use.

Try seeing if you can disable overscan on your TV.
Your TV might also have "ratio" settings, which you can try to change.

You could try temporarily changing your screen resolution in Preferences/Displays to see if you get the same issue. Certainly looks like a configuration problem on your TV. Hopefully there is a TV setting that will allow you to adjust overscan.

If you go to the displays preference pane, is there an option there to control the overscan?
If there is, try that.

Ah, I found it! It's called Underscan in the settings. Thanks, you both.
