Description tpgould 2009-11-11 22:50:22 UTC
For me the the resolution both of the body of an OO document, and of the controls (such as the sheet 
labels in Calc) depends on what display I am using when I start OpenOffice. I use a MacBook 15",  I 
have an external 22" (56cm) 1680x1050 display. If I start OpenOffice with the MacBook's built-in 
display, 100% zoom looks fine, and the "decorations" like the sheet labels and status bar are easily 

This is on Mac OS 10.5.8, updated as of 11/11/2009.

When I start OpenOffice with only the external display (MacBook is closed, and I use an external 
keyboard), 100% zoom is unreadable (small), and the decorations are also unreadable. I can zoom up 
the body text, but I have no way to change the small labels.

I suspect that OO is mis-reading the screen resolution, and making an incorrect adjustment for 
displaying fonts. 

The workaround is to open up the MacBook, disable the external display, restart OpenOffice, put the 
MacBook to sleep, and awaken it to use the external display. I don't see how to disable and enable the 
built-in display without sleep or shutdown. This is a very awkward workaround, and the procedure 
must be repeated if OpenOffice exits for any reason.

This is a different use case than the one described in
id=98581 as it does not depend on changing the resolution of the current screen. There may be a 
similar root cause, but both scenarios should be tested.

Have the same install (MacBook Pro 10.5.8, external keyboard & 1980*1050 22" Monitor). Works perfect: 
Starting OOo 3.1.1 when only the external Monitor is used (lid closed), the A4 page opens at 100% and is 
A4 on the Monitor (you may cover it with a page of paper - it fits), all controls are the right size...
Maybe a screenshot would help?

Here's a screenshot that demonstrates the problem. I don't know what difference is between our 
configurations, but this is wrong for me. I'm happy to gather any other information -- software installed, 
etc. I will try to reproduce this on a colleague's MacBook, to make sure it is not a problem with my 
particular system.

Please check issue 107076 if it is a case of this problem (esp. "-3rd party DVi switch") and if so, mark this 
a a duplicate.

Same here, observed on 10.6.2. Regular MBP notebook with 22'' external display.
Comment 7 hwieser 2009-12-04 19:38:15 UTC
Same here on 10.6.2
And BTW OOo loses its menu bar after reopening the notebook after sleep. Yikes.
