Concerns about DVI-VGA  Adaptor

My TV only get DVI outlet, so i got a VGA-DVI adaptor the other day to work with the original DVI-VGA adaptor. What i've done was simply to connect the two VGA outlet and plug-in DVI outlet to its repective terminals. However,although my Pro was able to detect the TV and identify its model as well, the TV had no reaction whatsoever. What's wrong with that? Did i connect them in a right way?
Thanks a million for your help?

To connect a DVI TV to a MacBook Pro, you need a DVI cable. DVI to VGA adapters block the digital video signals needed by the DVI port on the TV. Other signals do get through, which is how the computer identified the TV.

  • How can i use the DVI-VGA adaptor under this particular circumstance?????

    I got a LCD only has DVI-I port, while as u guys has noticed, the MBP only got DVI-I too. So, my first thought is to get another DVI-VGA adaptor. What i'm doing is to hook up the VGA port then plug each DVI port to LCD and MBP. Well, the problem comes out that MBP was able to indentify the Monitor but no image apears on Monitor. How can i solve this problem? Or do i need to buy any other accessaries to configure my MBP in order to make it work with the **** Monitor!

    Right. You don't need a DVI-to-VGA adapter to connect DVI-to-DVI, obviously. The included DVI-to-VGA adapter is not meant to connect to the external display/projector, but merely to give you the proper connection to connect the VGA cable of the display/projector. I give a lot of presentations, everywhere I go there is a long VGA cable (at the podium, conference table, etc.); the short adapter is nice because I'd rather not carry a long cable with me...

  • Mini-DVI DVI to DVI VGA adaptor issues

    So, I just bought a snazzy new black MacBook, and am wanting to connect it to my old 20" NEC monitor, which uses VGA. Since I already have a DVIVGA cable that I used with my old tower (and I figure I'll someday upgrade to a DVI monitor), I thought it might save some money to only buy a mini-DVIDVI cable, and use it to connect to the monitor via the other cable.
    Everything looked fine and dandy until I actually tried to connect the adaptor cables, which is when I realized that there are 4 extra pins on the male DVI end of the DVIVGA adaptor (2 above and 2 below the longer thin piece on the end), which don't have anywhere to go on the female DVI end of the mini-DVIDVI cable.
    I don't want to damage anything and ruin either of the cables, so I don't want to force them and break off or bend those 4 pins, but what exactly do they do, and why are they needed on that adaptor, when they apparently wouldn't be there on regular DVI monitor cables? Would it compromise the integrity of the DVIVGA cable if I did bend them out of the way? Or did I just screw myself into buying an extra adaptor that at the moment is of no use to me?
    I'll gladly post some pictures if anybody doesn't understand what I'm talking about and needs to see it themselves!

    the extra pins are the analog portion of the DVI-I DVIVGA adapter cable that you already had. they contain the analog RGB, sync, and ground bar that allows the adapter cable to be terminated with a VGA end (VGA is analog).
    DVI-D is the same as a DVI-I, except w/o the analog lines... which is what, unfortunately, your mini-DVI to DVI-D cable you bought is. breaking off the extra pins on the adapter would be the equivelant of cutting off the end of the VGA cable, in other words, not good.
    you will need to go back and purchase the apple manufacturered mini-DVI to VGA cable or adapter and appropriate VGA to VGA cable.

  • Mac-VGA-Adaptor to VGA-DVI-Adaptor: Is it possible?

    Well, I've never tried this but I'm wondering if it's possible to hook up a really old Apple Display to a newer Mac which only has DVI?
    To accomplish this it would be neccessary to use a Mac-VGA Adaptor like this:
    This will change the connector from DB-15
    to Standard VGA.
    Next I'd like to connect this VGA connector to the Mac via the usually included DVI-VGA Adaptor.
    Can anybody tell me if this is possible at all? I know that the solution would be FAR from perfect, but this would only be used occasionally for connecting not-that-old Macs (G3, G4) for testing purposes. If it's not possible I'll just get at least a VGA display for that. But I could get an old Apple Display for free, hence the asking...
    Thanks for your time!
    Björn

    Hi-
    I don't see why it wouldn't work, though you could just get a DVI to DB15 adapter. Google the term "DVI to DB15" for more options.

  • Mini DVI - VGA Issue

    I purchased a Mini DVI-VGA adaptor from Apple over a year ago. I've used it only to connect my Macbook to a projector. Once connected, the screen will flash briefly and then the resolution will change and I will be able to switch back and forth from single screen to dual screen by clicking F7...but this was back when things were beautiful and I had no issues.
    Now, my adaptor will not work...neither would another Min DVI-VGA adaptor that I tried...but yet the port will work when I connect my Mini DVI-SVideo/RCA adaptor.
    Is there a setting that I may have changed? It doesn't seem to be a hardware issue because the port will work with a different type of adaptor.

    Hi. I have pretty much the same problem: everything was fine until yesterday. As usual, the screen flashed briefly but then the resolution DID NOT change and the projector could not connect. After removing the adaptor, the screen flashed again but that's it but there was no difference as the resolution had not changed. To note that the adaptor is (grrrr) new (bought about a month ago). Could it be an issue with MAC OS 10.6.2? or maybe the firmware needs an update? I'd be glad if someone could help. Cheers,

  • Mini-Dvi - VGA Problems

    I just bought a mini-dvi to vga adapter from apple but can't get it to work with my philip's hdtv. It works perfectly when plugged into my pc monitor, but when going into the tv I just get a blank screen with "no signal detected". I've using a VGA to DVI convertor on the cable going into the tv, I know I should have gotten a straight mini-DVI to DVI cable, but I wanted to be able to use VGA as well.
    My old iBook worked perfectly, but it detected my tv as a VGA monitor, whereas the MacBook detects it as a HDMI display. Is there any way I can force OS X to set my TV as a VGA display? Or is there any other fix around?
    My tv is DVI-I in I think, which I read elsewhere has caused some conflict with mac mini's.
    Thanks in advance...

    Well, I just got myself a mini-DVI to DVI adaptor so that I could connect it to a DVI-VGA adaptor and on to my VGA (Apple) CRT.
    I may get a DVI-capable monitor in the future, so it seemed like a good future-proofing exercise. Unfortunately the DVI plug has four more pins (around the flat-blade pin) than the port on the mini-DVI adaptor has holes!
    so it doesn't fit.
    DRAT! I have been waiting for the DVI adaptors to come into the Apple Centre for a couple of weeks, and now it's no good! Grrr.

  • No Apple Remote or Apple Mini-DVI to VGA Adaptor included with new MacBooks

    Hi!
    I just picked up a new (black) MacBook yesterday from the Apple Retail Store in Meadowhall (Sheffield). I was quite surprised to open the box and find that the Apple Remote and Mini-DVI to VGA adaptor cable are now optional items and no longer included in the package. Okay, they're not expensive (an extra £30.00 to add both of them), but I just thought I'd mention it to let potential customers know.
    I have to say that I'm very pleased at the speed bump and the 250GB hard drive though (you can never have too much space). Also good to have 2GB RAM out of the box (rather than paying an extra £90.00 for the 2GB model). Excellent!

    bford0001 - 15% restocking fee? Did you buy it from an Apple Retail store? I bought a black MacBook from them just under two weeks ago (a 2.2 with 160GB HD and 2GB RAM) and they let me take it back and walk out of the store without charging me anything!
    One other thing I have noticed - why has the L2 cache dropped to 3MB from 4MB? I know the processor is more powerful, but doesn't that mean it would just about level out, because of the reduction? I noticed the same for the £1,299.00 MacBook Pro and that on the other two models, it's gone up to 6MB. Anyone know how this would change the performance?

  • Mini display port to dvi or vga adaptor?

    I currently use a MacBook Pro and want to use the mini display port to my 24 inch Samsung LCD screen. My question is should I use the mini display port to DVI or VGA? My Monitor has both ports on back. I know that DVI is Digital and suppose to be the superior source compared to VGA analog, but I have only used VGA when using my Monitor with my old PC and it seemed fine enough for me.
    If, I do go the DVI digital route will it be that much better graphics compared to just using VGA?
    Finally, has anyone hooked up a mini display port to either DVI or VGA adaptor into an LCD monitor? What are your thoughts, concerns, advice etc. I realize its a very easy thing to do, but seem tied up between using DVI or VGA port.
    Thanks,
    DH

    Diffferences are not remarkable but DVI is indeed better. I wuold then choose DVI.

  • Using a VGA monitor with Mac Pro: DVI to VGA adaptor cord & X1900 card

    I will be purchasing the MacPro with the ATI Radeon X1900 XT. However, I want to continue using my dual Viewsonic CRT screens till the end of the year until I make the leap to a new LCD display. I know Apple sells a DVI to VGA connector and in fact I believe it to be included as an accessory.
    Here is my question:
    The graphics card I am buying (the X1900) is designated as a DUAL LINK DVI. The Apple DVI to VGA adaptor cord has a DVI -I SINGLE LINK male connector. Will this DVI-I single link connector properly mate to the female dual link connector on the X1900 graphics card? If it will, I'm probably in business. If it won't, does anyone have an idea for a workaround?

  • Using second display via eMac's mini-DVI to VGA adaptor

    Hi,
    I've got a 19inch widescreen display from Acer, model no. AL1916W. I have apple's mini-DVI to VGA adaptor and have connected the second display to the point where it mirrors the screen on my eMac, however I don't want it to do this.
    What I had intended is that the second display would act as an extension of my eMacs screen, so I can drag windows across for extra space. Is this possible with the eMac?
    Put more specifically, I want to be able to put logic's main (arrange) window on the Acer widescreen, and then have whatever else on the eMacs screen? Is there a workaround to do this?
    help much appreciated,
    Toby

    Hi,
    It's funny you should send me that link, I actually found that a couple of hours after posting this and tried it. It worked perfectly, I now have the widescreen running in it's native resolution and working as a separate screen which I can drag stuff in and out of. I came back on here to mark the question as 'answered' but I couldn't find how.
    thanks for your help,

  • Mac Mini shows blue or pink tint using DVI to VGA adaptor on 800x600 HDTV

    My new Mac Mini won't retain the color settings for this TV/Monitor that is connected via the DVI to VGA adaptor. I've tried to find the display using the Mac utility. I finally got the Mac to create a color profile for the TV by plugging a USB cable from the TV to the Mac, while the VGA cable was also connected. The Mac displayed a new color profile called RCA/ProScan (the TV brand), and the colors looked acceptable. I then saved that color profile. The monitor would then revert to a very blue tint, or a very pink tint without notice. I thought it might have been when I disconnected the USB cable, or when I re-booted the Mac Mini, but I can't detect a cause & effect pattern. I might try to connect the TV using a DVI to S-Video adaptor instead of VGA, but I don't know if it will help. Can someone help? Thanks.

    Make sure it isn't a simple cabling problem. Check all the connections and tighten down the thumb screws. The mini is prone to a poor video connection and you need to make sure the video cables are tightly attached.

  • Which mini DVI to VGA adaptor?

    I have an 800MHz flat screen with a broken display.
    I have an old monitor with a VGA cable, but I can't find the correct cable to connect between the iMac and the VGA plug.
    I have a mini dvi to VGA adaptor, but it's not correct in that the mini DVI end is female on both the computer and the adaptor chord I have ):
    Can someone point me to the correct adaptor cable?
    Thanks,
    Luke

    Hey Luke,
    What you need is the mini VGA to VGA adapter like here:
    http://store.apple.com/us/product/M8639G/A?fnode=MTY1NDA3Ng&mco=MzI3MTYx#overvie w
    If you buy it at the Apple store make sure they understand that that's the adapter you need and for what machine you need to use it on. Then if they give you the wrong one you can take it back.
    On a separate tack I had a problem with the socket on a 800 17" that had come off the logic board. Symptom was no video no picture but worked fine with external adapter (mine had to be jiggled a bit to get it to work). I just sent it to Superior Reball to have it resoldered. Cost $51 plus shipping one way. That would take someone knowledgeable to take the iMac apart.

  • Using DVI to VGA adaptor with HDMI to DVI port on Mac Mini Server

    Hi - I couldnt find anything on this, so I decided to post a new topic. We just recently purchased a Mac Mini server at work for iOS development. Before we launch in in one of our data centers and start remoting into the system, we need to conduct basic setup on the system.
    For this, we pulled out an old stock VGA montior we have around the office, and found an apple DVI to VGA adaptor (http://i51.tinypic.com/2mzb4lc.jpg)
    The problem is, the pins dont exactly line up... on the DVI to VGA adaptor there are 2 extra pins above and below the horzontial pin on the left hand side (http://i52.tinypic.com/2mxhg1j.jpg) that do no exist on the Mac Mini HDMI to DVI adaptor (http://i53.tinypic.com/2ywesrp.jpg).
    Ive checked other converters and it seems that all of them are setup the same way, with two pins above and below.
    Has anyone else had to deal with this issue? I really dont want to go and buy the Mini DisplayPort to VGA adaptor for one-time use.
    Thank you!

    Welcome to  Discussions!
    What you are seeing is the difference between an analog and digital DVI connector, as DVI as a specification can provide both types of signal, depending on implementation. When used in a mode where only one or the other type of signal is provided, the different connectors prevent a mismatch. VGA being analog, the DVI to VGA adapter is using an analog DVI connector. The other connector you are dealing with is a digital only connector. HDMI is digital only, hence the HDMI to DVI adapter being digital only. Thus you can not adapt from the HDMI port to VGA with just passive adapters, you would need a conversion device between. It would be cheaper and more effective to use a Mini DisplayPort to VGA adapter.
