OS X :: My MBP13 Detected The Ext Display But Still Doesn't Display Anything?
Jun 7, 2010
i m using LG22inch monitor, it is a vga cable connected to a dvi adapter connected to a dvi miniport.
initially i tried to plug it in without AC power, but ext monitor screen is black. I surfed the net for some solutions, it says tat the AC power must be plugged in for the external monitor to work.
However, when i plug in AC power, the ext monitor is still sleeping, even though i can detect it in my profile settings.. what can i do to wake it up?

The title says it all really... Quite a simple problem that I can't find any answer to!
I've hooked up my 30" Apple Cinema Display to the new iMac 27" and the highest resolution I'm getting as an option is 1280x800... The iMac correctly detects the ACD as a Cinema HD display but limits my resolution. Why oh why?!

I recently purchased an LG Flatron monitor to use as my second display for my MacBook Pro (unibody). I had it working with great results for about a week, but today when I plugged it in, the monitor is not detected. I have been looking through other's problems trying many of the same things, to no avail. [URL]

I have a MacBook Air and am trying via DVI cable to connect another display? The Mac will not detect the other screen. Any suggestions would be terrific. Do I need to "install" the old screen?

I have a 2009 model of Mac Mini and I have a 32" Samsung TV as the primary display hooked up though MiniDVI converted to VGA and it works properly. But my second Sony 19" monitor hooked up though DisplayPort Converted to VGA does not receive signal. It is detected by Display but no signal is being sent to it. When I have only the monitor though the DisplayPort hooked up it doesn't receive signal but when I have one only though the MiniDVI it displays fine so I know its not the Monitors.

I have a Hanns-G 22in monitor that I'm trying to connect to my new Macbook Pro. There's a DVI cable connected from the monitor to the macbook pro with a little converter cable. I've tried what seems like every iteration of sleeping, turning off, and turning on both the laptop and the monitor to no avail. The monitor always remains black as if it's connected to nothing. I know the monitor is good, too, as I use it for my PC on a daily basis.

My wife's macbook monitor is destroyed due to happy 2 year old. It won't be worthwhile to replace the monitor and it is not fixable without some expensive work being done on it, therefore I would like to use our TV as an external monitor and retire the macbook to being a mediia computer. I have connected it to the TV, and I see an empty desktop, as far as I can determine it looks like it is treating the TV as a secondary display - that the desktop is extended onto - so I cannot actually interact with the normal desktop. When I try to run things using keyboard shortcuts I hear some sounds of things starting, but I don't see anything on the TV.  So what I need to do is to have some way to tell it to treat the secondary display as the primary display.

I have set in my Energy Saver Prefs to have my display turn off in two minutes and have the computer never turn off while plugged in. I am running MBP with NVidia GeForce 9600M (I have the option to go to "Better Battery Life" and switch it to 9400 if I so choose.)
Is anyone else experiencing this problem? Can somebody try to replicate it and tell me if it's just me? This happened when I installed 10.6.3, .2 was fine.

I have a mid 2009 iMac that doesn't have Thunderbolt display, but has a mini-dvi port.Will the Thunderbolt cinema display 27" still work when connected to this mini-dvi port? I thought it would be better going for a thunderbolt display monitor rather than the older version, so when i upgrade my machine in the future it stays compatible.

I have a shell script running on a Linux machine to generate multipart mail messages. These display perfectly in Thunderbird (PC or Mac) but the html is missing when I open them in Mac mail. Switch to plain text and they look fine, but the html just doesn't display.
I've tried Snow Leopard and Lion with the same result.Â

I own both an iMac and a MacBook.Lately I've been trying to use [URL] and while the website does work, it displays totally wrong on my iMac ?I looked at all I could think of (not a newbie, but not savvy enough to go look in the coding to look for errors there).The one section from the site which displays correctly is one without a menu on both right and left. It's a blog. Here's a clue, I guess. I tried with both Safari 5.1.6 and Firefox 13.0, with the exact same result. But on my Macbook it displays perfect! I am using Firefox 12.0 on it. So I downgraded to Firefox 12.0 on the iMac... no success.Of course I also cleared the cache, closed the browser, and the computer... no luck.I then removed all plugins, since it was the only remaining difference...I thought it could be a difference in display... altough I couldn't see how... I changed it from 1920x1080 to the ones similar to my Macbook's (1280x1024 and 1280x720)... Of course it was the same, just more blurry. It doesn't make sense and I hate it when it doesn't make sense!Of course I hate it even more that I can't use that website on my iMac!!! (or with a lot of hassle).Â

I was messing around with the ownership & permissions on my external HD and I think I may have switched it to no read & write.
Now when I plug the HD in, it shows up in Disk Utility and System Profiler but not in Finder. I've verified and repaired and neither of those things seem to help.
I'm not sure if what I did screwed it up or not.
I have some pretty important stuff on the HD. Do I have to reformat? Is there any terminal command or somthing that I can do to get into the HD?

Mail 5.2 (OS 10.7.4) no longer displays embedded images. This happened after I installed an AirportExtreme wireless router. I can send images as attachments, but received mail with images displays blue box with ?. Using "download image" has no effect. Mail/preferences/ has " Display remote images in HTML messages" checked. The answers to similar questions don't seem to apply, or I just don't understand them.

I've followed this tutorial to put together a html signature for Apple Mail : [URL]
So I've tested it with this simple file: [URL]
This should just display the logo. I've saved this through safari as a Web Archive file and saved in onto the Web Archive file of Apple Mail in the Signatures folder.
Then opened Apple Mail again. As you can see, while composing the mail the icon turns into the blue question mark icon. I've later sent it to my private email address and it arrived as an image.

I have a white plastic macbook which appears not to be able to connect to my wireless network. All the other PCs and a Mac Mini in the house connect fine, but the macbook does not.It has connected since i got it, both to the home network and a network in school, but today it promted me for the wireless password, connected a few times but did not give me a IP address, and now will not connect at all! The network appears in the list, i click on it, enter the wireless password, then it says connecting before connection failed.
The network setup is a Cisco router connected to the modem and then connected to the wireless too. There are no computers connected via cable to the network.

I just bought the 27in iMac to hook up to my Mac Pro till apple refreshes their ACD. I thought I would be able to use the Mini Displayport to DVI adaptor to connect it to my Mac Pro through DVI and it doesn't work. I know you can do it with mini displayport to mini displayport although, both my mini displayports are currently in use by by 24 ACD.

I love my MacBook Pro -it's used all the time in schools, without hassle.
However, when I try to connect to a Sony VPL ES1 data projector, the screen resizes (normal and OK) but the data projector shows a completely different desktop image and I can't see a cursor.
Presume this is a bug, but is there a work-around I'm missing?

I select my desktop picture, and it puts it as it. But once I shut my computer off and turn it back on, it's back to the Lion desktop picture. But when I go into the system preferences, it says that my picture is the one that I selected before.

Have a brand new MBP 13" using Thunderbolt-DVI adapter with my old Dell 2405 LCD. Have an interesting scenario ... when the display goes to "sleep" there is still some type of signal coming out of the display port. The monitor will stay on and just blink "NO SIGNAL DETECTED ON INPUT 2". But the monitor actually still stays on.When I put the entire laptop to sleep them the monitor will properly power down to sleep mode.Â
I don't think its the monitor because I've used this monitor with a number of different machines and graphics cards, in every scenario when I had the display set to sleep it powered off just fine. Â

I'm getting a high resolution, and it looks alright, but it's not fully using the widescreen. That's "aspect" right? Well anyway, I also have a 19" display and it works perfectly. My Xbox, cable box and movies all use the full widescreen on the Acer, but the Macbook with the super amazing Mini DisplayPort doesn't even use the full resolution. What's with that? I thought the reason they had this new port and a $30 adapter was for higher resolutions!
