sweetapple Posted May 23, 2014 Share Posted May 23, 2014 I installed maverick on the t410s based on instruction on this website and everything works fine. However, I am using a 27" crossover LCD as external monitor connected to the T410s docking station's Display Port. If boot the t410s, initially the external monitor will be able to show the darwin boot HDD options and the initial screen of OSX booting. However, when it comes to the pint of inputting the password, the external monitor screen goes black and I can see the Display Port got no signal. Is there any way t enable external monitor? Thanks!

Moderators Jake Lo Posted May 23, 2014 Moderators Share Posted May 23, 2014 That's the limitation of the patched FB. You can read more about it here.It specifically mentioned that you can't have both LCD and External monitor, it's 1 or the other by switching FB.

sweetapple Posted May 23, 2014 Author Share Posted May 23, 2014 thanks very much. Is there a way to switch between external and internal? I actually am happy to have only one at one time. The fact that Maverick always keep both on makes me nut. So I need to adjust the FB (frambuffer?). I have limited knowledge on this and hopefully you can shed more light. Much appreciated!

Moderators Jake Lo Posted May 23, 2014 Moderators Share Posted May 23, 2014 Which version of OSX Mavericks do you have?I'll update some files for you to test since I have not try this personally. I have always been using just the LCD.As you can see from the previous post, DP is shown as unknown, so probably not tested. If this doesn't work, you might have to stick with VGA.

sweetapple Posted May 23, 2014 Author Share Posted May 23, 2014 thanks soooo much. My version is 10.9.2. Also my external LCD is 27" with 2560x1440 resolution Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted May 23, 2014 Moderators Share Posted May 23, 2014 The guide from the link above only mentioned VGA, so I can't say if it'll work. Guess you'll just have to test and report back. Here's the instruction: Download attachedT410s.zip Backup DSDT.aml and FB from Extra/Extensions Replace file with attached, use the FB for LVDS-DP Launch myHack/myfix (quick) Restart your computer. Instruction from guide:While OS X is booting up (you see the Apple boot logo in your internal LCD display), connect your external VGA DP display. At one point, your internal LCD display will become disabled (black screen) and your desktop will appear in your external VGA DP display. That's it! If the native resolution of the external display is not correct, you can fix it by going to System Preferences>Displays. If the native resolution is not detected, you may have to install SwitchResX. If this doesn't work, I guess dP doesn't work. Then you'll have to replace FB with LVDS-VGA and try again. Link to comment Share on other sites More sharing options...
sweetapple Posted May 24, 2014 Author Share Posted May 24, 2014 Thanks! just tried, but the laptop hangs shortly after plug in DP and stays white screen. I guess DP does not work. Link to comment Share on other sites More sharing options...
Jessiah8511 Posted December 4, 2014 Share Posted December 4, 2014 Any updates on this? I've been looking for a way to get DP to work as well. I've been looking around at different forums and websites and looks like the fix for VGA is all I see. I would love to have this as a Mac Mini as I have several of these 410s laying around at work. Any help would be great. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted December 4, 2014 Moderators Share Posted December 4, 2014 If you set it as a mac mini, you'll get external monitor through VGA, but loses the internal LCD. Is that what you want? see here under External Display (Experimental) for more info. Link to comment Share on other sites More sharing options...
