thenewone Posted October 30, 2013 Share Posted October 30, 2013 Running Mavericks on a Dell XPS M1530 My laptop's display is cracked and barely functional and so I wish to use an external display as my main and ONLY display. Mirroring is a no-go because my external display is a higher resolution than my laptop's native resolution and so it forces it to be displayed at a lower resolution, making things look blurry. Extending the desktop option allows me to keep my external display's native resolution (as well as making it the "main" display), but then the graphics card is forced to work unnecessarily hard by keeping the laptop's display going (even if it's "dimmed" or "off" using the clamshell method). How can I disable the laptop's screen altogether so that the system doesn't even recognize it as an option anymore? Can I edit a .plist file or set a boot option to make it look like the laptop display doesn't even exist? I know there are tricks to make the laptop display "turn off" when in mirror or extend mode, but everything I've tried and come across doesn't actually stop the system and graphics from recognizing the display and therefore still have to work harder to send it "information." Any help is appreciated, thanks! Link to comment Share on other sites More sharing options...
dcai777 Posted October 31, 2013 Share Posted October 31, 2013 can you phisically remove the display? Link to comment Share on other sites More sharing options...
thenewone Posted October 31, 2013 Author Share Posted October 31, 2013 That did cross my mind...perhaps that is the best option after all. I'll brave it tomorrow and report back! Link to comment Share on other sites More sharing options...

thenewone Posted October 31, 2013 Author Share Posted October 31, 2013 Worked beautifully! I was initially afraid the pre-boot screen (to see bios and whatnot) wouldn't display on the external screen once the internal display was removed but it does! Happy now 1 Link to comment Share on other sites More sharing options...
dcai777 Posted October 31, 2013 Share Posted October 31, 2013 Good! You can mark the post before this one as the solution in which you disconnected the display. Link to comment Share on other sites More sharing options...
