Connect monitor to macbook

I just bought a used monitor that I want to hook up to my MacBook which only has USB ports.  The monitor comes with 3 adaptors, FoxFire, USB and somethings with lots of needs that look very old fashioned.  When I plug the USB wire from my monitor to the MacBook  (and plug the monitor into the electical outlet).  The on light on the monitor comes on, but there is no image on the screen.  I have OS X 10.7.5  What is wrong?

I've connected plenty of computers to monitors, and never have used a USB port. Is your monitor old? It seems yourMac can't be that old as you are running Lion.  I'm just guessing here, but your monitor has a VGA connector (15 Pin)
is this the connector on your monitor?
If this is, you need a DVI to VGA adapter to connect. If not let me know and I will walk you thru this.   All the best

    How to connect an external monitor to macbook pro. The monitor has no usb connecter, only a port.

    Most MacBook Pro models have a Mini DVI port, a Mini DisplayPort or a ThunderBolt port for connecting an external display. USB does not have enough bandwidth to support a responsive display connection.
    What model MacBook Pro do you have, by year, CPU speed or MacBook Pro 3.1 designation?

  • HT3382 Connect from a MacBook Pro's mini display port to a Display Port monitor?

    Hello everyone,
    Is it possible to connect from a MacBook Pro's mini display port to a Display Port monitor with resolutions higher than 1920 x 1200? It seems Apple does not supply a mini-DP to DP adapter.
    However, just as they do not make a mini-DP to HDMI adapter, but they do recommend a Belkin product for this purpose.
    Is there any reason that a mini-DP to DP adapter or cable wouldn't work and support high resolutions?
    Thanks for your feedback!

    Hey tjk,
    Thanks for the response.
    Do you have any recommendations for a potential set up? The audio output and Apple DVI are on different sides of my MBP, which is alright, I guess I can get two long cables to handle each. I was hoping to just have my MBP closer to where I use it, with a cord nearby plugged in on one side to the HDTV and resting near where I keep my MBP for when I want to use the HDTV as an external monitor.
    With a converter like this, you can run video out of the MBP's DVI port, and miniToslink (optical) audio out of the 3.5mm stereo mini jack to the converter, then it will combine the two and output audio and video through HDMI to the monitor.

    Otherwise, depending on the TV's inputs, for video you could run DVI to DVI on the TV, or DVI to HDMI to the TV. For audio you could run 3.5mm stereo mini plug from the MBP to RCA adapter on the TV. Toslink/optical is also an option.

    18. What is the maximum resolution available for use with the Apple Mini DisplayPort to VGA adapter?
    The resolution available with the Apple Mini DisplayPort to VGA Adapter is 1920 x 1200. VGA displays that use higher refresh rates (such as 85 Hz) at resolutions of 1600 x 1200 or greater may not generate video properly until you lower the refresh rate.

    If the detect displays option is not available, hold down the Option key while you are in the Display pane.
    How do I select additional resolutions on my display?
    You can use the Display pane of System Preferences to specify how your display works. Not all options appear for all display models. By default the best resolution for your display will already be selected in System Preferences.
    To select a different resolution, use the Scaled option. Some additional resolutions may be available when you hold the Option button.
    I hope this information helps ....

  • I have connected my new Macbook Air to my existing Samsung large external monitor with a VGA adaptor but I can't get the full mac desktop to display. No icons but then websites are coming up. Help!

    I have connected my new Macbook Air to my existing Samsung large external monitor with a VGA adaptor but I can't get the full mac desktop to display. No icons but then websites are coming up. Help!  Further info:  I am a complete newbie to Mac.  Had three macs prior to 2000 then four PCs.  Just come back and struggling a bit with the unfamiliarity. On my old PC laptop I could simply switch from the laptop screen to the large external monitor (and back)  with the F4 function key.  While I can get the background image from my MBA to display, that's it.  Until I noticed on the far left of the external monitor, the very edge of one of the web pages I was on.  So Idragged it over to display in the centre.  But that's all that's there.  And now I have gone out of those web pages but they are still displaying on the monitor.  There is some wierd disconnect.  I'm sure it is just a setting thing.  Will keep searching for answer but any advice welcome!

    Your dsplay is getting extended onto the external monitor. Chcnage the setting to duplicate it or only display on the external monitor and you should be fine,
    Let me know if this worked for you.

  • More DIsplay Problems on HPx2301 Monitor when connected to my MacBook Pro - OSX Snow Leopard

    1) HP x2301 monitor
    2) OSX 10.6.8 AND OSX 10,7
    3) On-Screen Message "Monitor Going to Sleep"
    I previously reported that the problems with my new monitor had been fixed with a change in DVI cable.
    Unfortunately the fix lasted for one day.  I powered off both the monitor and macbook, came back the next day and the monitor no longer detects the power book.  Same is the case with an iMac and an old mac-mini.  My external older Viewsonic (connected also via the same DVI cable) has no problems. 
    When the monitor is connected to the macbook, the macbook detects it and acts like it has dual screens - the System Preferences>Display app shows both monitors (and allows me to change resolution of the HP.  Dispite this, the Monitor cannot detect a signal from the Mac.
    Looks like a defective Monitor - will be contacting HP in the morning.
    Also of note is that the included Documentation describes 6 control buttons on the base of the unit, including an Auto Adjust button for the user to " Press to activate the auto adjustment feature to optimize the screen image."  Unfortunately, there are only 5 control buttons - there is no Auto Adjust button.
    The documentation makes no mention of OSX, although it appears that drivers for the monitor have been included in the OSX distributions.

    I'm back up - now using HP to mirror laptop screen.  Got replacement DVI cable from HP, plugged it in an Monitor is working (again).  So I have 3 seemingly identical cables - 2 supplied by HP, and one an older one I used with a Viewsonic DVI monitor.  
    1) The cable that shipped  with the Monitor never worked,
    2) The older cable worked for one day with the HP,  then stopped working on the HP monitor, but worked with the older VIewsonic monitor,
    3) The replacement cable from HP that is working currently.  
    I believe they are all DVI-i - pins appear to be identical on all three.
    So I don't think its a settings or cable type issue.  I suspect that the HP may have some circuitry that makes it very persnickity when it comes to signal detection - so perhaps there's some small variation is signal quality btween cables - not sure how to check that though.
    We shall see if the cable 3 works for extended period.

  • How do I connect my defunct MacBook Pro (monitor's dead, HD works fine) to another computer to transfer files?

    I have an old MacBook Pro whose monitor recently died. I took it to the genius bar to get assessed and ended up buying a MacBook Air to replace it. The genius hooked up my external hard drive to the MacBook Pro and did something with the way she started up the MacBook Pro so that I could get my files off of it and onto the external hard drive while it was plugged into another computer so I could see the files there. However, I failed to transfer some files that I really want. Now I'm trying to figure out how to transfer them on my own. And I can't make it work.
    Here's what I have to work with:
    - The monitor-less MacBook Pro, which still turns on.
    - The new MacBook Air.
    - The external hard drive, which I connect to the old MacBook Pro via 6-pin FireWire and the new MacBook Air via a thurnderbolt-to-9-pin-FireWire-to-6-pinFireWire converter.
    Would love to hear your ideas so I can avoid another genius bar appointment if possible (as they take forever).

    FireWire or ThunderBolt, whichever you can make work in common.

  • Need help connecting Dell U2713HM monitor to MacBook Pro

    What is the best way to connect a Dell U2713HM monitor to MacBook Pro OS 10.7.5 to maximize the resolution 2560 x 1440? I was using a VGA adapter on my old Viewsonic monitor that hooked into the Thunderbolt port, I think. When I use my old adapter with the new Dell monitor, it stops my Mac from responding and the monitor says it has no DVI connection. When I unplug the adapter from my Mac, it starts working again.  I'm not very good with all these port options and descriptions so talk real slow, please.

    1 Dual Link Digital Visual Interface connectors (DVI-D) with HDCP
    1 DisplayPort 1.2 (DP)

  • Connecting an External monitor to Macbook pro.

    I have a macbook pro I want to connect it to an external monitor which has HDMI how do I do this is there a thunderbolt cable that can connect to HDMI

    What Macbook Pro do you have? Does it have an HDMI port? Does it have a minidisplay port? If it has an HDMI port get an HDMI cable. If it has a Mini display port get a mini display port to HDMI adapter and an HDMI cable.
    Does ypour monitor have other than an HDMI port such as a DVI port?

  • Using a remote desktop connection with the Macbook pro.

    I use the remote desktop connection on the Macbook pro and am unable to exchange info between the mac and the remote connetion windows. For example, if I am writing an email from the remote connection and want to attach a document, photo etc. that I created on the Mac, it just doesn't work. It seems like the Mac and the desktop connection are completely seperated eventhough they are both on the screen in front of me. the systems I use for work are not Apple compatible and will not work on anything other than windows explorer and in my case the remote desk top connection. Any ideas!

  • How can I connect an old macbook pro...

    How can I connect an old macbook pro with that does NOT have a Thunderbolt connection to a new 27 inch iMac? I only need to do this for one specific purpose, to be able to see the work I'm doing on the laptop in InDesign on the iMac's larger screen (at a larger size as it were, so I can see a double page spread (or even a whole page would be an improvement) in one go)?  I gather it might be possible to get an adaptor but note that Apple don't seem to sell one. I know I could do this with the cinema screen but would rather do it with a new imac as that will have more use to me overall. It's a work laptop which I don't own so I don't own the Indesign to just be able to use that on an iMac. I have tried to connect monitors to the laptop in the past, but with no success at all.  I hope someone can help . Thank you.

    Im pretty sure you are talking about the M8536 which has an ADC Adapter.
    you will have to daisy chain a thunderbolt to DVI adapter with an DVI to ADC Adapter.
    the first adapter:

  • External monitor for macbook pro

    How do I go about connecting my 2006 MacBook Pro to an external monitor?

    Oh man. It should not fail on all three of those monitors, especially the Apple one. There aren't really any steps for you to miss, when you plug in an external monitor it should light up within seconds without having to make adjustments. I hope there isn't anything wrong with your MacBook Pro's video card, but of course that is something that can't be diagnosed easily in a forum.

  • External monitor for macbook air 3,1

    Bought a Samsung external monitor to connect to my macbook air 3,1. Connection failed. Phoned Samsung who told me I needed resolution of at least 1900 X ? . Only have 1366X768. Is it possible to find a monitor, or can I do anything to upgrade the resolution on the macbook?

    If you get a monitor with DVI input then get the Mini Displayport to DVI adapter.  If the monitor is HDMI then Mini Displayport to HDMI adapter.  In each case you'll also need the DVI or HDMI cable as well.

  • Dual 2560x1440 monitors on MacBook Pro

    Hello,
    Will the current 15" Retina MacBook Pro support 2560x1440 resolution through it's HDMI port? I would like to run dual 2560x1440 resolution monitors and would like to power one via Display Port and the other via the HDMI port if it's possible.
    I did see Using 4K displays and Ultra HD TVs with Mac computers - Apple Support but was not sure if anything between 1920x1200 and 3840x2160 would work.
    Thanks!

    Can't OP run one display from each of the Thunderbolt connections on his MacBook Pro Retina machine (with the thunderbolt to whatever adapter) OR the HDMI? MacTracker says "support for two Thunderbolt displays" in the "Memory and Graphics" tab.
    I don't have one so not sure, but MacTracker is pretty good about this sort of stuff. Also OP might want to look at How to setup dual external monitors on a MacBook Pro 15" A1398? and am sure there are others.
    Good luck.......
