HT3235 VGA adapter not matching up to Monitor/video port

I have an inFocus LP70+ Projector along with a Apple VGA adapter (Apple part M8639G/A). Am trying to connect it with an older iMac 8,1 desktop and finding that the Monitor/video outport does not match up to that adapter. Help?

Do you have an official Apple adapter or did you get a third-party one? If the latter, that could be the problem.

Lightning to VGA Adapter not working with certain apps

I've recently noticed that I can't watch movies on Netlix any more with my Lightning to VGA Adapter going to an LCD monitor. It works just fine with other apps just not Netflix. Apple says it is a Netflix app problem, and Netlix doesn't want to admit it's anything wrong with their app. Any one else have this problem? Is there a solution?

G5 dvi to vga adapter not working

DVI to VGA adapter not working with my G5 Dual 2.3 GHz Power PC. I am trying to use a VGA Monitor but can not get a signal. I also am using a Dell with a DVI Input and that works fine using a DVI Cable from my G5 to the Dell u2410.

Bad adapter?
The G5 ports are DVI-I. Any good DVI-I to VGA adapter should be fine.

I have a MBPro mid 2013 with 1 Thunderbolt port. Just bought a Mac monitor and want to daisy chain a PC monitor to it. Use a Mini DVI to VGA adapter from MBP to PC monitor. How do I daisy chain the 2 monitors?

Hall Palm Desert,
if your Mac monitor has Thunderbolt ports, and the PC monitor is on the end of the daisy chain, then you might be able to do it by connecting your PC monitor’s VGA cable to a Mini DisplayPort-to-VGA adapter (e.g. Apple, NewerTech), connecting that cable’s Mini DisplayPort end to one of the Mac monitor’s Thunderbolt ports, and then connecting a Thunderbolt cable between the other port on the Mac monitor and your MacBook Pro.

Mini DisplayPort to VGA adapter not waking monitor

Hi,
I've had my Mac mini for about a month now (the 2010 model with 2.4GHz Core 2 Duo and 2GB of RAM). Initially I had it connected to a 32" TV via HDMI which worked perfectly. However I have now switched to a 24" Iiyama ProLite E2410HDSD which doesn't have a HDMI socket. I've bought a Mini DisplayPort to VGA adapter.
Whenever I put the mini to sleep or switch it off, the display does not come back on. To get it to work, I have to unplug the adapter from the mini and plug it back in again. Is there any way to get it to work all of the time?
Thanks,
Thomas
Edit : Just booted into Windows 7 using Boot Camp, and putting that to sleep and waking it works perfectly!

I think I know what's wrong, but I don't know of a good way to fix it. The Iiyama is not constructed correctly. It appears that it's DDC channel goes down when it's sleeping, which it shouldn't do, unless it allows auxiliary power on the VGA cable to keep the channel active, which it also seems like it isn't doing.
Does the Iiyama have a DVI input? That might work better with the correct adapter. Although if they messed up the architecture of the VGA port, they may have messed up DVI, too.

Dock to VGA Adapter Not Working

I just bought this device with great excitement only to now be seething with anger! I hope I'm doing something wrong and someone else has experienced this, overcome and now able to help me. I do not see an exact match in past posts on this topic.
Basically the device does not appear to work. I have so far tried with an HP LCD monitor and also an Acto projector: both do not detect a signal from the device. This was with Keynote and Goodreader (latest version with VGA support). I've tried re-powering, removing the cable putting back, landscape/ portrait orientation etc etc.
Is it that this device only works with specific VGA devices?
Any pointers greatly appreciated. Thank you.

Don't be angry podpad.... But I know what you mean! It would appear the VGA adapter only works in certain apps - those written to use it. The vanilla iPad only projects in keynote - when you 'play' the presentation and non DRM protected video... Yes irritating. However, I've seen several new apps come up that do support it - and a few upgrades now include it... We just have to wait.
Check out goodreader (as previously mentioned) for documents - PDF etc and Webshow (only 59p) for showing web pages.
The rest we'll have to wait for but perhaps we can keep this thread going with apps that support it and what they support!
If it's worth it... I thought it would simply display the iPad screen in everything... I was a bit peeved it didn't!

Mini DVI to VGA adapter not working

Hello -
I just purchased a new Mini DVI to VGA adapter to use with my Mac Book. The day I bought it I plugged it in and worked great! Now after disconnecting it and reconnecting back to my Mac Book things are not so good. When I hook everything up to each other the monitor shows "no signal". Using Systems Preferences/Detect Display does not help at all. Am I missing something obvious here? I'm a new Mac junkie.

Here is an Apple article on the subject of having no video on an external monitor. It's written about the Mac mini, but it applies equally to any other Mac.
http://docs.info.apple.com/article.html?artnum=301345
And here is another Apple article that is more generalized and with fewer suggestions, though it might be a good place to start from. Good luck.

Mini DisplayPort to VGA adapter not working under Vista (Boot Camp).

Hi there,
I'm facing a very serious issue with MacBook Pro Unibody running MS Vista under Boot Camp: using the Mini DisplayPort to VGA adapter to hook a projector is 95% impossible because the only resolution available is 640x480 or sometimes 800x600. No solution came from the adaptor firmware update, still same behavior: connecting the external projector/monitor toggles 640x480 resolution with no more choices available. Just 5% of attempts on selected projectors gave me access to the complete resolutions list.
This is having a serious impact on my job where I do need both Mac&Windows running natively and with external display capabilities, please I'm looking for some feedback from users facing the same problem or someone who had an official answer on this issue from Apple. Do avoid posting about using modded display drivers please: I know they exist but the adaptor should be working with original ones.
I can understand Apple does not support MS Vista issues but this seems to be a hardware/driver one.
I'd like to point out I'm using a clean Vista installation with Apple drivers (from the Leopard DVD) and I've run Vista (same version, same gfx drivers etc) under Boot Camp on my previous MPB (with integrated DVI output+adapter) on hundreds of different projectors with never a single problem.
Any feedback is really appreciated.
L.

I'm having the same problem. When I try to connect to the switch in our conference room (connecting both a flat panel display and/or a projector, both with much higher native resolutions), all I get is 640x480. This is a huge problem to using bootcamp, and I really need to get this to work. I was able to get a higher resolution 1280x800 on a separate, portable display, so I'm wondering if people have the problem with standalone projectors or only with projectors connected to some sort of switch, in my case an Extron MPX423A. I have also tried this in both Windows Vista (32-bit) and Windows 7 RC1 (32-bit), with the bootcamp drivers and the latest NVidia drivers, and the behavior is the same all around.

DVI-to-VGA adapter disabled on HDMI-equipped monitors?

Can anyone with an Apple DVI-to-VGA adapter on a Core Duo or Core 2 Duo (both at 10.6.8, currently and probably forever) still connect to a second monitor if the monitor also has an HDMI port? I could until early 2011. From 2008 to 2010 I could connect to every VGA monitor through the DVI adapter.
I thought the DVI-out on my MBP died but got a newer MBP and it, too, doesn't work on any HDMI-equipped screens. Both computers and all my DVI-to-VGA adapters work fine on monitors without HDMI. Yes, I rebooted. No, it's not the cables. Again, all components otherwise work in other arrangements. I am not talking about any other setups. The HDMI-equipped monitors all work fine with miniDisplayPort-to-VGA plugs (today!) from newer Macs.
Any work-arounds? Anyone have a best-recommendation on an adapter that works still?

Thanks, BSteely, I have the latest QT and iTunes already. Closing the lid seems to kick the MacBook external display into some special mode that Front Row can't display videos in. For example, you get the Front Row interface, but as you select movies/TV shows, the preview window on the left side is blank. Open the cover, and have both displays going, and you can see the previews fine (and of course, you can see the movies/TV shows play fine as well when you click on them)
Running Quicktime Player full screen works fine without Front Row in either open or closed lid mode. So it is apparently something wrong with Front Row itself.

Lightning to vga adapter not working after ios 7 update

After I installed ios 7 on my iphone and ipad, lightning to vga adapter A1439 stopped working on both machines. I thought that the first update would solve this problem. However, I recently installed 7.0.3 update but both machines still can not see the adapter. I tried adapter on different ios 6 machines and it works just fine.
Will there be an update for this issue? Did you have the same problem?

Thunderbolt to VGA Adapter not working with SMART board all of a sudden?

I was wondering if anyone had any suggestions on getting my classroom's (I'm student teaching) SMART board connected to my macbook pro (13 in). Two days ago I tested the setup I had, Mini-DVI to VGA adapter, Mac OS X SMART software suite and it worked flawlessly. Today I try the setup and although the SMART board recognizes my macbook via usb, the projector does not display anything. System preferences does not even recognize the projector as an external monitor. When I plug in my Mini-DVI to VGA adapter (already attached to the VGA cord from the SB) the screen flashes black and goes back to normal. Official work from SMART technologies is there is no supported adapters for connecting a macbook to a SB but I have seen numerous threads about this setup working and like I said it was previously working fine. Any suggestions on what to try next? I was thinking of dual booting to an older version of OS X. Thanks.
Specs:
MacBook Pro 13 in
2.4 GHz Intel Core 2 Duo
4 GB 1067 MHz DDR3
10.9.1

If your laptop is not connected to power (i.e., plugged in to a wall), try plugging it in. It is not uncommon for a laptop to send the VGA signal out with less power when it is on battery power. I've seen this fix this problem, at least, dozens of times.
Try connecting the VGA cable to your adapter while the smart board display is on THEN plug the adapter in to your computer.
Also, try connecting the VGA+Adapter to your mac before booting it (or connect the macbook to the vga cable and then reboot the macbook). I've seen this work with macbooks using vga on projectors (or other external displays running through longer cables or crestron/extron/whatever switching equipment) many many times too.
If these fail, get your campus AV (or IT) people involved. We have often found that a damaged cable or long run needing amplification will work with some computers but not with others. It could be that the cable running from the smart board is somewhat sketchy.
Also, have you attempted to connect your macbook to any other display since starting to have the issue? A bad dongle (dp to vga adapter) isn't rare. I have a bad one sitting on my desk at this very moment.
One last thing you can try, this works for some:
Shut of the mac
Connect it to the smart board (i.e, connect the cables)
Turn on the mac and then close the lid
This *may* boot the computer on the external dispaly (smart board)
Open the lid before it comes to the login screen.
Hopefully one of these suggestions helps.

VGA Adapter Not Working in Windows 7 (64 bit)

I was running Win7 (64 bit) through bootcamp and could not get the VGA adapter to work. I've tested it and it worked fine while under OS X. In Windows 7, it could detect the secondary display, but my monitor no has signal. I was re-install windows, but no work anytime. Anyone else encountered this issue and have a fix?
I have a early 2011 13" Macbook pro - 2.3 GHz/4GB RAM

But I have it worked fine a week ago! I think that stopped working after firmware update...

VGA adapter splitter? 1 external monitor for desktop and macbook

I recently bought the Apple VGA adapter and it works great with my macbook and external monitor. However I use that same external monitor with my desktop PC. It's becoming a pain to constantly unscrew and plug out the VGA cable. So I'm trying to find a VGA splitter that has 2 male ends and 1 female end, but I'm not sure if something like that even exists. Basically I want to be able to use my external monitor with my macbook and pc without having to unplug the monitor's vga cable from my desktop. If anyone can give any suggestions that'd be great. Thanks!

You shouldn't try a splitter cable as you would have interference from the two signals. You need a VGA switch box like one of these.
