I have a Samsung Laptop but would like to use Cinema Display with mini displayport. Is that possible?

I have a Samsung Lap top but would like to use Cinema Display. The only connections on my lap top is HDMI and VGA. How can I get it to work?

Thanks Malcolm. I saw this on the apple site
Kanex C247D Single-Link DVI to Mini DisplayPort Converter
Will that work?
I also spoke to someone at apple..They told me to get 2 cables. Mini DisplayPort to Dvi and Dvi to Hdmi..Connect the 2 and it will work...Do you think it will work? Just to save$$$

Having problems connecting a late 2011 Macbook Pro 2.2ghz i7 to a Sony KDL-32L5000 using a display miniport to DVI adapter (DVI to VGA cord). The TV is not detecting the macbook. Anyone have this problem?

You really have to mess with the resoluton, espescially the refresh rate, as it varies from projector to projector, monitor to monitor. Even within the same brand! Because so many manufacturers are trying so many different things to become the next cool kid on the block, and the way the formats are being configured that's now part of the game.
That's why so many professionally produced corporate shows hire a dedicated projectionist for the video presentations. Too many bugs in the honey.
Refresh & sesolution are the first things to look at.
Just so you know that colors in PowerPoint PC, and PowerPoint Mac, don't exactly match... go figure.
I forgot to mention another thing, sometimes it's the projector that needs to be tweaked.

How do you use multiple displays with a MacBook Pro and iMac

I have an iMac and a MacbookPro laptop both upgraded to OS X 10.9 (Mavericks). I'd like to use multiple displays with them. Can I do this without an Apple TV? They are both on the same network. If I can, can someone please give some instructions on how this can be done?
Thanks!

Both computers have ports for external monitors. Check your user manuals. Only one display can be added to the MBP, but newer iMacs have dual Thunderbolt ports.
Do your own Google research to learn what to do, but reading your manuals should be all you really need. It' not rocket science yet.

How do i set up a second display for my iMac desktop? I want to use both displays at the same time.

how do i set up a second display for my iMac desktop? I want to use both displays at the same time. My iMac is the 24" Late 2006 model. I recall that there is a cord for plugging in a second monitor, but I want to make sure that i can use both monitors side-by-side at the same time. thank you.

If the Display supports DVI, then you will need a > Mini-DVI to DVI Adapter and a DVI cable.
If the Display only supports VGA, then you wiil need a > Mini DVI to VGA Adapter and a VGA cable.
Noting that the (digital) DVI is far better than the (analog) VGA connection.

I want to have my itunes visualizer on my TV which is connected via HDMI adapter, and still have access to full screen itunes and my desktop on the main display.
Any suggestions? App downloads that can do this? Please let me know.

You can't do it. This has been an issue since Lion.

Method to use to display (n) number of strings

hi,
I have a list of strings stored in an array, I need to be able to show these on screen after pressing a button. I am not sure what to use to display these, I setup an action listener on the button to create new JLabel for every string in the array which are created using a while loop, as the number cant be predefined. however by adding a new label to the panel it will only update after having left the screen and come back to it, is there another method I could use as this is obviously no good, maybe I should not use labels to display the strings. However I cannot create a preset number of labels, as the number required is unkown.
any ideas?

If you want the really cheap way to do it, you can use a label with multiple lines by putting <html>...</html> tags around the text and <br> between the lines. :-)
The way we do it here though is to use a JTextArea which is formatted to look like a label.
JLists are another way to do it, but JTextArea can wrap the lines, which JList cannot.

I have a 17" Macbook pro with flickering red and cyan(blue) lines across the screen. The issue disappears temporarily when I tap on the computer, and the problem does not occur when I use external display or try to screen capture the problem.

I purchased my Macbook (17") through a certified apple tecnition in August 2012, it was refurbished and the motherboard was completely replaced. I do a lot of photo editing, but I have been unable to do so because of the red vibrating lines that interrupt my screen. The issue disappears temporarily when I tap on the computer, and the problem does not occur when I use external display or try to screen capture the problem. I brought the computer back to the technition I purchased it from and he said that it was a problem with my fan, so I have two new fans but the issue is still occuring. He says he doesnt know whats wrong. Does anyone have any information on this issue?
Here is an image of the issue

I recommend having your Mac serviced by someone competent. A force sufficient to "blow apart" the fans was clearly excessive and may have damaged the display cable, as well as any number of other problems.
Dust is properly cleaned with a vacuum, preferably one designed for computer service, and they are not cheap.
Compressed air should never be used. It just blows dust everywhere, often into places where it can no longer be removed.

Using Cinema Display - Please Help

Hi All,
I have been working with my new 15" MBP and loving it, not one problem to report! I will be traveling with the MBP and when I come home, I would like to use this computer with my cinema display and apple wireless keyboard and all of my other home office stuff. Can you please tell me the correct way to use my cinema display with the MBP, I have never owned a laptop before - but this MBP is clearly better than my old G4 Powermac and I would like to keep everything on my new MBP rather than using two computers anyway.
Also, is there an extension cable available for the cinema display to run from the monitor to the MBP?
Thanks!

It would be nice if you could be a little more specific with your request. The only correct way to use a display is to plug the DVI cable into the MBP. There should be something in display in your system prefs that will give you the option to mirror you laptop on an external display. Once you do that everything else should just work (assuming you plug it all in). When you say an extension cable you mean just for the video portion, right? Not any usb/firewire ports? If it is just DVI take a look here. http://www.newegg.com/Product/Product.aspx?Item=N82E16812712028
that is a 10 foot dual link DVI cable. It will support through a 30" display so that should be a great cable. I hope this helped.

MacBook suddenly won't detect my display, Using Mini Display Port to VGA?

MacBook suddenly won't detect my display, Using Mini Display Port to VGA?

dohdoh1985, I have the exact same problem also! I recently bought a 42" RCA LCD TV. I connected my MacBook Pro to my TV using a Dynex Mini DisplayPort to HDMI adapter that I got from BestBuy. It worked great until I upgraded to Mac OS 10.6.4 and then it suddenly stopped working. Same TV, same settings, same cables, same adapter. Nothing changed since the last time it worked except that my OS was upgraded to 10.6.4, so i am assuming that is the culprit. The symptoms are EXACTLY the same as what dohdoh1985 described; when I plug in the TV, the laptop display flashes (3 times) as though it is detecting an external display and the picture on the TV briefly goes from blue to black for about 1 second then back to blue. The TV does not appear in the display menu / control panel and there is no sign that the MacBook detected it. I went through the usual troubleshooting steps (reset PRAM, checked connections, tv settings, etc) but nothing worked. Other HDMI sources (i.e. Blu-ray player) work fine on the TV using the same HDMI cable on the same port so there is nothing wrong with the cable, the TV or the TV's input settings.
Meanwhile, I can still connect my MacBook to my external ViewSonic monitor at work without any problems. It's just the TV that's not working.
I cancelled my cable subscription a while ago since I only watch shows online nowadays and this was my only way of watching TV shows, so I'm quite upset.
Apple, please help!

Hello chrispyw,
If your content is still being displayed incorrectly, I would check the resolution setting for the built in display with this article:
OS X Yosemite: Adjust your display’s resolution
If it keeps happening whenever you use AirPlay then I would use this section of the following article to reset the display system:
Apple computers: Troubleshooting issues with video on internal or external displays
Reset the system
You can reset the Mac's parameter RAM and SMC.Reset the resolution
Start by resetting the Mac's parameter RAM. If the display does not come up, was previously set to an unsupported resolution, and still results in no video:
Start up in Safe Mode.
From the Apple () menu, choose System Preferences.
Choose Displays from the View menu to open the preferences pane.
Select any resolution and refresh rate that your display supports.
Restart your computer.
Thank you for using Apple Support Communities.

CPU is very hot when using Thunderbolt display and mac attached USB hard drive for TimeMachine

Hello,
i've bought the new MacBook Pro 15" and a Thunderbolt display. Everything works fine for me due to the latest updates, but i experience an issue which i really don't understand. When i connect an usb hard drive for TimeMachine to my display it works like expected (CPU has a temperature of 64°C), but when i connect it to an usb port of the mac while using my display the CPU temperature goes crazy (spikes about 80°C) and it gets very noisy. Has anyone else experienced this behaviour?
May this has something to do with the dual graphics adapter and how the system handles the data stream to thunderbold ports and usb devices? Which graphics card is used for the external display, the internal gpu or the adapter from ati? I've googled a lot but haven't found appropriet answers about these questions.

Hi there ulairi9!
I understand how this would be a frustrating issue! I have an article here that can provide some troubleshooting steps for you, and can hopefully help you resolve the issue. That article specifically addresses the issue you are experiencing, and can be found here:

Using VGA display without EDID possible?

Hello,
I plan to buy a Mac mini in the near future but I have a rather specific concern about the display connectivity in advance:
Is it possible to use an analogue VGA display that doesn't deliver any EDID/DDC ( http://en.wikipedia.org/wiki/EDID ) with the current Mac mini via the Display Port-VGA adapter.
I'm asking this because a PC with nVidia GF9400 onboard graphics and Windows 7 or Vista immediately turns off the VGA signal when the OS is completely booted.
I have a MBP (4,1/Early '08) and could use the display in question with the DVI-VGA adapter after manually setting the correct resulution and refresh rate.
Can I safely assume that the Mac mini's GF 320M behaves the same way with the Display Port-VGA adapter? I don't have any device with a display port output yet so I can't really test it myself.
There's a concerning customer comment to the Display Port-VGA adapter in the German Apple Online Store stating that this customer couldn't connect a Samsung LCD TV with the adapter.
Thank you very much for the help!

Thanks for the tool tip. Seems like the display has EDID after all:

Can you evaluate these details? Am I good to go?

My thuderbolt display is 3 weeks old which I'm using as display for my mac mini. I no longer get the display on but can hear the sound. Please suggest.

My thuderbolt display is 3 weeks old which I'm using as display for my mac mini. I no longer get the display on but can hear the sound. Please suggest.

Make sure the mini-displayport/TB plug is fully seated. It may look fully plugged in but isn't.
Make sure the Displays system preferences has an Arrangement tab. No Arrangement means the monitor is not being detected.
Do a smc reset.
If none of this works I suggest you take it back to apple (along with your mini).

Using External Display Only - Gaming

Hi,
I want to be able to connect my HP w2207h 22inch widescreen external LCD to m'y Macbook Pro running leopard to allow me to play games such as SPORE and The Sims 3. I have already set the external monitor as primary in os x but every time that I start the games that I want to play, the whole screen goes blank (both of them) and the external screen turns itself off. I then have to unplug it to get the picture to appear on the macbook again so I can exit. I still have no idea how to play these games on the external display with this problem.
I have been able to solve this problem in bootcamp however, with the function to turn off the macbookpro display and keep the external by itself. I really want to play these games in os x and on my external display.
Does anyone know how to do this or how to make it so that the macbookpro screen isn't used at all (i.e. the external display is the only one in use)?? Some third-party application?
Cheers
Tim

Timmy, that doesn't seem logical, buddy. If you use the MBP keyboard, I'm quite sure that it thinks u wanna use the MBP display as well. It would seem an inconvenience, to me, to have it open while using another display, anyway. I'm with the idea of using another keyboard & mouse. That's what I do.
I have a ? for ya. U mentioned that u know how to get the external display to be primary while using BootCamp XP. I have done that in the past with no problem. However, it quit working. If I close my MBP, the display turns off & XP will not allow me to do anything until I open the MBP & log back in. If I try to leave the MBP open off to the side & use the Cinema Display as primary XP laughs at me & will only open the game on the MBP display. In XP Settings, the option to uncheck the MBP display as primary is grayed out & there is no option to turn on mirroring for either display or set the Cinema Display as primary. How were u doing what ever u did to use your external display for gaming on BootCamp XP?
