Thanks, but I have duel monitors but I am not able to have one large desk top to view my landscape picture on. Previous OS updates allowed me to expand my desk top so one picture could be expanded to be viewed half on one screen and hllf on the other screen. Why won't Yosemite allow me to do this?
What are you seeing now?
Are the display mirrored?
I have no problem using extended desktop and having an app extend on both screens
OS X Yosemite: Connect multiple displays to your Mac
Also what do you have set for spaces? Yo may hae it set so each app has it own space
I am rereading all of the instruction on duel monitors now. This problem only started when I updated my OS to Yosemite. Until that time I had one large desk top.
As I asked before, what do yo have now?
Mirrored displays?
Extended display that can't span monitors?
If you go to System Preferences>Mission Control what is checked?
I have all checked in mission control. Both displays display two separate screens. Two menus on top. I can slide a picture from one to another but will not show on each screen. In system preferences, displays, I have tried every move.
What do yo mean by "I have all checked in mission control. "?
I only have "Group windows by application" checked. and I can have one app extend on both monitors
I only have "Group windows by application" checked now but still no change from my original problem.
So what happens when you try to pull an app across both screens? Mine does not snap to both screens
as long as that box is checked, each display is independent.
If you want the original "Extended Desktop":
Uncheck the box
close the preference pane or switch to another and save changes.
I've got it now IIIaass and Grant Bennet-Alder. Thank you very much for your speedy help. The problem was that I had the monitor plugs reversed which of course I didm't realize after I installed a new card. Boy am I dumb. It's been that way for awhile now too. Just didn't realize it until you folks started me retracing my steps from the installation. Thanks again.
