External gateway display

I have a gateway FPD 1500 monitor that I'm trying to use as an externals display for my Mac book pro with retina display (highest specs offered)
I purchased two adapter on amazon to connect the monitor to one of the thunderbolt ports on the computer
One of the adapters is a thunderbolt to DVI-D single link female
The other is a DVI male to DFP receptical adapter
Both specifically say that they work with both Mac and PC
I rigged it up, connected the 24 volt power supply to the monitor, which was working fine for many years on an old PC
I plugged it into the computer and the screen flashed blue on the mac for a minute like it should and then it went back to the way it was before like nothing had happened
The light on the gateway monitor turned solid amber after turning green for a split second after plug in
I am already using a 22 inch Samsung tv for an external monitor and I thought it would be nice to use the gateway too
Help is much appreciated!

Hi,
It didn't detect the display properly. I played around with switchres X and tried to manually adjust the settings but that didn't work either. I have since realized that I will be better off using my other mac connected through the DVI connection on my monitor since I use that for photoshop work. That may change when the universal binary of photoshop comes out though.
Currently I am waiting for my VGA adapter to come in. So, no, I don't have the problem solved yet, I'm afraid. I am hoping that when my VGA adapter comes in that will work. If it doesn't I will have to take further action to get this fixed and deal with Apple Care.
JMF - are you using the same Gateway monitor? Curious to know if I am just doing something wrong. If you find out a way to get it to work, please let me know.
Thanks

  • External Monitor display issue

    The external monitor for my mac book pro displays large/wide text when both screens are open.  If I shut the laptop, the external monitor display returns to a normal view.  I tried going to system preferences, displays and it's either on best for display or in scaled, the maximum 1920 x 1080.
    Please advise.

    Where is extended display mode? In display screen, the mirrored mode is checked, both displays are in 1920 x 1080, not sure what else I can do here?  BTW: it just started happening (all was normal on both screens) until I used laptop at my work and connected it to external screen (school) with VGA adaptor (at home I use a DVI).

  • Imac does not detect external vga display

    Please help with connecting external vga display to an imac 21.5'', late 2012, OS X 10.8.5 via Mini DisplayPort to VGA adapter.
    I have connected an external monitor (Fujitsu Siemens) to the thunderbolt port of the imac using a Mini DisplayPort to VGA adapter. The imac does not detect the external monitor. I have followed all instructions and suggestions I could find at Apple Support Communities without success.
    The monitor is in perfectly good working order as it has no problem connecting and performing flawlessly with a dell windows laptop. The imac, connected via the Mini DisplayPort to VGA adapter to the D-Sub connector of a Samsung smart TV, also worked perfectly.
    To add insult to injury, occasionally, when restarting the iMac with the external vga display connected and powered on, the iMac screen starts intermittently turning blue for a brief second or so and resuming back to normal. The frequency of 'blueing' is once in 2-3 seconds. This particular rather disturbing problem, luckily ceases when the external display is switched off.
    Any advice and help with resolving the above connection problems will be gratefully appreciated.
    Thank you

  • Brand new macbook pro 15" when connected to external LCD display in high resolution ,flickers often

    Hi,
    I have brand new macbook pro 15" with retina display.
    I have connected external LCD display (Samsung B2230) using Apple VGA adaptor & thunderbolt port. But LCD display flickers quite oftenly. I read community blogs where many macbook pro users like me are facing similiar issue.
    There is no problem with LCD display as it works fine with Lenova laptops.
    Can anybody please provide me the solution to this problem.?

  • External LCD Display & Screen Spanning

    Hi All
    I need to connect an external LCD display to my iMac G5 1st Gen computer.
    Is this the right cable -
    http://store.apple.com/Apple/WebObjects/ukstore.woa/wa/RSLID?mco=6C04E099&nplm=M 8639
    Also I have been reading in this forum about a screen spanning hack to the firmware. Sounds painful but what are practical steps to set this up?
    Many thanks in advance
    David

    G'day mate
    Thanks for the reply from Oz.
    Just had another good look at the back of the external LCD and it has got both VGA and DVI ports on it. Which will get the best results do you think?
    Also here is a dump re the graphics card in my iMac -
    GeForce FX 5200:
    Chipset Model: GeForce FX 5200
    Type: Display
    Bus: AGP
    Slot: AGP
    VRAM (Total): 64 MB
    Vendor: nVIDIA (0x10de)
    Device ID: 0x0329
    Revision ID: 0x00b1
    ROM Revision: 2103
    Displays:
    iMac:
    Display Type: LCD
    Resolution: 1440 x 900
    Depth: 32-bit Color
    Built-In: Yes
    Core Image: Supported
    Main Display: Yes
    Mirror: Off
    Online: Yes
    Quartz Extreme: Supported
    Display:
    Status: No display connected
    As you can see, the card is a GeForce FX 5200. The web site refers to iMac G5's with GeForce FX 5200 Ultra cards and not the GeForce FX 5200. (My iMac is a Rev A machine).
    Do you think this will cause issues? I need to run the iMac and the LCD at a show for my company and I am a bit concerned that I might end up with a Mac with no working display. Is that likely?
    Cheers

  • External Drives display as folders?

    I’ve got a question about external drives display in the folder tree. For some reason, when I add a folder on an external drive, I get a new “Volumes” folder, and then the drive appears as a folder under the “Volumes” folder. So, instead of having a quick view of which drives are connected, I get a bunch of “missing images” question marks on the folders when the drives disconnect.
    I don’t get the extra collapsable bar (Under Macintosh HD) as in your video. This happens on several drives every time I’ve tested it!
    Any advice?

    Hi Victoria! 
    Thanks for the reply.  Here's what happens:
    Right clicking on "Volumes" shows "Hide this Parent", not "Hide Parent Folder". 
    When I click on "Hide This Parent", the entire structure underneath "Volumes" goes away:
    Just for a lark, I right-clicked "Pictures", (my top level parent on my internal HDD), and was prompted with this:
    which I have not clicked yet.  Because I'm scared.  Is this what I should be doing though?

  • Since 10.8.5 an external connected display has problems

    Hi there,
    since my Update to 10.8.5 an external connected display via miniDisplayport to HDMI (or DVI) makes problems. If i turn on the display and the macbook (cold start), everything is working fine. But when i turn off the monitor or close the lid of the macbook and return later, he won't recognize the external display anymore. If i connect via HDMI, i have glitches all over the external display and then it turns black. If i connect via DVI, the external display stays black. Mac OS X doenst shows me an external connected display in the settings..
    Does anyone else have this problem?
    If i restart the Macbook, all is working fine again...

  • I'm in the market for a laptop.  Which of Apple's laptops will I best connect 2 external monitors/displays?

    I'm in the market for a laptop.  Which of Apple's laptops will I best connect 2 external monitors/displays?

    I've just bought a Pro Retina. As far as I know this is the only one which will connect 2 external monitors running different programmes ie not cloned.
    You use the 2 thunderbolt ports for the DVIs (if they're not Apple monitors)
    You need 2 thunderbolt to DVIs. MiniDisplay port to DVI might work too (MIGHT WORK! Not sure yet) and these are a lot cheaper.

  • Gateway FPD2185 21 inch as external macbook display

    Has anyone used one of these monitors as an external display for the macbook? I am having problems getting 1680 X 1050 resolution on it when connected to my macbook via the DVI mini to DVI adapter.
    I had problems originally getting my mac mini (ppc) to work with this monitor at first and had to get a copy of SwitchResX and fiddle with it to find a stable frequency. I have tried SwitchResX on the macbook, tried some of the same things and it doesn't seem to help.
    Anybody have any suggestions?

  • External preview display via. Mini-DVI to video adapter QUESTION

    Hello, I have been browsing this forum for a while, and this is my first question.
    I have a Macbook Core2duo running Final Cut Pro. I purchased a Mini-DVI to S-video/composite video adapter.
    I cannot get my work to preview on this external monitor. I would like to view the canvas on the monitor while working. I had this setup at school on a G5, but I cannot get it to work on my macbook. The only way apple suggests doing this is by setting up a camera via. firewire and then run from the camera to the NTSC video display (television). I would just like to do it via. mini-dvi to my television for previewing.
    Any help is greatly appreciated. Thank you,
    Morgan Bressler

    From what I've been told, using the computer's video output isn't outputting a true NTSC picture. I was told when talking about how the Macbook Pros dropped the S-vdieo port that I shouldn't use that anyways, but rather to go the firewire route. THat was actually converts the video source to true NTSC instead of taking a computer output to a TV. While I have no doubt that it works, I'm willing to bet that you'll see a noticeable difference between the G5 S-video and your MB using firewire. Most consumer camcorders from the past several years do digital (firewire) to analogue (NTSC) conversion, so you probably don't even need a new box.

  • Connecting MacBook Pro 13 inch to external LCD Display

    I just got a new MacBook Pro 13 inch without retina display.  I noticed the retina display comes with an HDMI port, but the one I got does not.  It has the newest update to OS X Mountain Lion.  The best external connector I could find was the Thunderbolt connector, but the TV I have is HDMI.  So I went to Amazon and bought an HDMI Cable and a. HDMI-to-Thunderbolt Connector.  I can now connect my MacBook to the TV, everything show up, but it's a little touchy with sizing.  Does anyone know how to fix the sizing of the external screen, so that when i go full screen on the TV, the edges of the window are past the edges of the actual display?  Right now, I can't seem to figure it out.   Maybe I should try a different hookup?

    Update:  turn out, i figured out the sizing issues, it seems to be filling the screen perfectly now.  But when i go full screen on one display, the other screen goes fullscreen on a gray screen.  I can swipe between fullscreen apps, just like in a single display situation, but when i do, both screens switch.  Is there a way top display one full screen app on the moniter and have the regular home screen display on my actual laptop?

  • MacBook Pro 13 + LG W2240T - No external monitor display

    Hi all. Have a brand new MacBook Pro 13 and LG W2240T connected with the MiniDisplay-->DVI-D adaptor. When I plug in the adaptor the screen on the Macbook flashes, the LG immediately says "DVI-D Power Save Mode" and then goes black. When I click "Detect Displays" it shows that no external monitor is attached. If I unplug the connector the MacBook display flashes. I think the Macbook is seeing something but it isnt sending a signal to the display. If I unplug the cable from the monitor I get a general "check signal" message floating around the screen. Dont think it is a problem with the screen. I dont want to have to shell out another $30 for a MiniDisplay -->VGA adaptor and use an analogue signal with the beautiful new digital display.
    Any hints or suggestions appreciated.

    I'm having the same trouble. Actually, my Macbook detects the monitor but no signal is reaching it. I am using a DVI-A cable from what I can tell. There appears to be a DVI-D or DVI-2 type cable available as well.
    The connection is as follows:
    Macbook Mini Display Video output to (Mini Display/DVI adaptor) then the DVI-A cable to a DVI/VGA adapptor (sub-D monitor connector) to the external video monitor input. I can see a "No Signal" message when I use a "picture in picture" function on the external monitor screen but get just a black screen with the monitor set to full screen VGA input.
    So do we think the trouble is the type of DVI cable or is there some further Mac secret handshake that I need to prompt the output from the Macbook. The odd thing (to me anyway) is that the Macbook recognizes the monitor by its brand and model number after doing a "Discover Monitors" search. But the signal does not reach the monitor and I don't know if there is anything else I need to do or if it just doesn't work.
    Further info is that I just tried disconnecting the DVI input, which I use as the main video connection to my monitor and I get the stock "arora" screen image from the Macbook but that's not what is currently being viewed on the Macbook screen. So perhaps I can just set the Macbook to "Mirror" the displays and use the DVI connector. The trouble with that is that the DVI connector is occupied on both of my external monitors. I haven't even tried the other monitor yet as it's a plasma TV in another location.
    What do you guys and gals think is the best and most cost effective fix here? I just want to be able to output signal from my Macbook onto the larger displays so that I can work more comfortably.

  • How to connect external 24'' display to a Satellite A210?

    I am using an lcd tv as an external display for my satellite a210, connected with a vga cable. But I cannot just use the external monitor, I can only use both at the same time. Also, the maximum analysis I can get by using them at the same time is 1280x800, because that's the laptop's highest analysis I guess. Are there any drivers I need to download or is it something I can't resolve?

    Hi
    Generally speaking you can switch between the devices using the FN + F5 key combination.
    It should be possible to output the video signal on both devices (notebook & external screen) and only on external screen.
    I think you should change the external screen resolution to a lower level
    As mentioned above, the 24 supports high pixel rate and I would reduce this to the same like supported by notebook screen.
    PS: you can also update the graphic card driver if an newer is available.

  • Why can't I get an external HDMI display after upgrading to Maverick?

    I've been hunting all over for an answer to this problem.  I upgraded to Maverick in the fall and recently discovered that I can no longer get a picture on an external TV via Thuderbolt + HDMI.  I've used new connectors and cords.  Apparently others are having similar issues after upgrading.
    I've tried the SMC reset option, but it has not rectified anything.  I've unchecked the "display as separate spaces" option.  Nothing seems to work and I've searched all over the support community for the answer, which can be extremely daunting.

    You said you have a workstation with 4 drives, not a notebook.
    And you have not reformatted in years.
    Just clone Mac OS X Lion (and Lion Recovery) to anotehr hard drive with Carbon Copy Cloner.
    Cloning as a Backup Strategy
    Or backup and erase the DRIVE, like WDxxxxx and not your "Macintosh HD" volume and restore.
    Reformatting is a good idea when moving to a new OS and lot of changes to partition structure go on each time, sometimes even mid-stream of a version.
