Helix / Mini-port to vga / Monitor flickers

New Helix. New mini-vga to vga adaptor. Two different monitors. Same issue .... the monitors blink and are unusable. Have updated every driver that I can think to update.
Any ideas?

Which Mini DP to VGA adapter are you using?
Check if there is a firmware update available for your Mini DP to VGA adapter

Apple Mini DisplayPort to VGA Adapter flickers

I have 2 Samsung SyncMaster 23 in, HD Displays connected to my Mac Mini. The Display connected via the Mini DP to VGA adapter flickers erratically. This started happening after installing the latest upgrade of OSX Mountain Lion. I called Apple support, they gave me a list of steps to try to fix the problem, which I followed to the letter, to no avail. The problem is annoying, to say the least. I tried to find out if there was a firmware update for the adapter, but I am running the latest firmware (1.03).
I would appreciate any help to solve this issue.

Thank you for your message.
1. Both monitors only have VGA input.
2. The other adapter, Mini-DVI to VGA has always worked properly.
3. The Mini DisplayPort to VGA adapter is an Apple original product I bought at an Apple store. I bought 2 adapters.
4. Actually I have 2 Mini DisplayPort to VGA adapters: The one I use with my Mac Mini, and another adapter I use to connect my Mac Book Pro to a Panasonic projector.
5. I have tried using both adapters, and the flickering problem is present using either adapter.
6. I believe the flickering problem is definitely something that needs to be addressed and solved by Apple. The adapter is its product, and should work as advertised, no matter what version of OSX I am running. Please remember that there was no flickering before I upgraded to the latest OSX Mountain Lion.
7. I do not believe buying an adapter from another manufacturer, as you suggest, would solve the problem.
Thank you for your help.

Female Mini port to VGA adaptor?

Hey Everyone
I am looking for female Mini port to VGA adaptor, and i wondered if anyone knew if something like this was made?
Thanks for any help or suggestions

Well i have the display hooked up to my MBP, which is all great.
But i want to use the display for my Xbox 360 as well. I have the VGS adapter for the 360, but need an adapter to plug the miniport in to.
Any thoughts on how to solve this?
Thanks for any help BSteely.

HT1338 cannot connect my MacBook Air to a projector -does not detect and 2nd monitor. I have a new Mini port to VGA cable made by apple. When I read online I see that many people have the same problem - Is this an Apple defect??????????????????

I cannot connect my MacBook Air to a projector - It will not detect a 2nd monitor or display. I am using an Apple made Mini Display port to VGA adapter. As I read online I see that many other peple are having the same problem. Is this an Apple defect!!???? If so it just burst the bubble about how great macs are. I never had a problem with that on a PC. I hope I am wrong. What can you tell me?

Hi There,
I have had the exact same issue but with a projector.
The issue lies with Mountian Lion 10.8.2.
I tried many a combination with no luck to get HDMI working.
Took my mac into the apple store and came to the conclusion it was the software, so I asked them to install 10.8 onto it (this is destructive so a backup is a must)
Bought my macbook home and voila, now displaying through my projector.
There is a small graphics update after 10.8.1 which seems to be the cause.
Hope this helps.
Thanks.

Can I use a Mac mini with a VGA monitor?

The Mac mini web page lists an Apple Mini DisplayPort to VGA Adapter as an accessory, but the Mac mini doesn't appear to have a Mini DisplayPort.
The Mac mini also has an HDMI to DVI Adapter included, but would this allow a VGA monitor to be connected via an additional DVI to VGA cable? ie. can the HDMI port provide an analogue signal that a VGA monitor can receive?

Some Mac Minis do have mini-DisplayPorts. In these two it is between the HDMI and the USB ports:
(yes Thunderbolt should accept mini-Displayport).
In this one it is between the Mini-DVI and the USB ports:
Only the oldest Intel models would you need a different adapter to VGA
Those you would need a DVI to VGA adapter from Apple such as this one. Note, DVI to VGA is converting digital to analog, and not very useful, unless your TV has neither DVI nor HDMI. DVI is much better converted up to HDMI. And the audio would have to come in separately. So depending on your display model and make, you may be asking for the wrong adapter. VGA is fine if all you are going to do is view DVDs on an old TV. But if you want the ability to use the Dock, menubar, etc..., it is good to have a 1080p TV with built-in HDMI or better.

How do you hook a 2012 Mac-Mini to a VGA monitor

How do you connect a thunder bolt (or HDMI) 2012 Mac-Mini to the secondary VGA input on my LCD monitor?

Get the Mini DisPlay port to VGA adopter. It plugs into the Thunderbolt connector

Mac mini to 2 VGA monitors? IS it possible?d

I am very interested in purchasing a Mac Mini. I would like to connect it to 2 VGA monitors. Is this possible? And if yes, how do i go about getting this done.

Yep. However the quality won't be on par with digital connections like HDMI and DVI. You will need a mini Display Port to VGA adapter ( http://store.apple.com/us/product/MB572Z/A ) as well as a HDMI to VGA adapter ( http://www.amazon.com/HDMI-VGA-HD15-Male-Cable/dp/B001OLCHJ6 )

External VGA Monitor flickering

Hi, I own a t520 and from day one, my external connected VGA monitor Samsung has some flickering. Its hardly noticeable but in dark colors like black you can notice it.
Its only happening on the external monitor and I connected it to another laptop and the issue is not there. I only have this with my Thinkpad.
Is this a hardware problem?

Yes, you are right, I did not tested it with another cable yet, and its a cheap VGA one, but it does not do this on on a very cheap budget laptop. Maybe the VGA port on the Thinkpad is very sensitive. Its running on 60 Hertz. I only have 50 and 60 to choose. And I always run on the highest.

Why to i have to plug in my mini display to vga monitor each startup

each startup my vga monitor will not come on unless I unplug and replug in my mini display adapter. then it comes on...does not happen in the sleep mode.

No, and no. I would make an appointment at the Genius Bar and have it checked out. A full 30-second hang is also not normal. Five or six seconds, I have seen. Thirty? Never.
Easier said than done, nearest Genius Bar is an hour away, also machine is out of warranty. As I said it's been doing it forever, probably plugged it in 300 times. It only has the long hang once every so often. I'll live with it.

New 2012 Mac mini having screen resolution problem when I connect to either 27" LG or 22" Hannspree monitor. Tried mini display port to VGA/HDMI and HDMI to DVI-D cables... all same isse

New 2012 Mac mini having issues in connecting to third party Monitors. Connected my mac mini to a 27" LG monitor. Text looks blurred. Tried connecting to the monitor using 3 options. 1) mini port to HDMI, then HDMI cable to LG monitor. 2) Mini port to VGA, then VGA cable to monitor 3) HDMI port on mini mac to DVI-D cable then DVI to DVI cable... In all cases text is not clear. Anyone has similar issues with latest mini mac. The monitor works fine when I connect to a windows 7 Samsung laptop. Any input is highly appreciated. Thanks in Advance

Why do you use always 2 cables? There's a lot that can go wrong.
1.) Hardware:
- Use only one cable, best an HDMI->HDMI cable. It doesn't need to be an expensive one, they've proven to be no worse than those "esoteric", expensive ones.
- Set the monitor to the HDMI input.
- The modes you are listing are only "picture modes" changing color/brightness/contrast settings, not resolution or the likes, so pick the one you like best later, or enter your own settings under Custom.
2.) OS X:
- Usually the Mac detects the screen itself and chooses the best settings, so by default you need to do nothing than make a proper hardware connection to get a decent image.
- However, there have been issues with new Mac Minis and particularly their HDMI ports. But reportedly they have been fixed with a software update. So, launch the App Store and check under Updates if there is one for you to install. If so, do it; otherwise you should be good to go.
- If you require, go to System Preferences -> Displays. In the Dispaly tab, by default, "Best for display" should be selected, and that is typically true. If you want, select "Scaled" and 1920x1080, plus a frequency from the list (where higher is usually better, but just pick the one that works best for you). If you can't see a change to the better, you best go back to "Best for display".
- If you are not happy with the colors on your screen, you'll find eventually more than one choice in the Color tab, though your particular screen should be in the list and its Display Profile should get you the best result. (Double-check picture modes on your display: if you're far off there, you won't make it much better with the Mac's settings).

Mac Mini Won't Boot with VGA Monitor Connected

I have a new Mac Mini connected to an older VGA monitor using the Apple brand VGA adapter. The mini is fully up to date and runs perfectly when booted. However, if I reboot the mini with the VGA monitor connected, it fails to boot. I just hear the faint chime sound every other second. There is no output to the monitor and the only way I can get it to boot is to disconnect the monitor and then power cycle the mini. I can reconnect the monitor just seconds after powering back on and it finishes booting properly.
Anyone else experience this? It is very frustrating. I've also tested with an HDMI connected monitor (without the VGA adapter) and it boots just fine and the display works properly.
Thanks!

Okay, I'm back with good news: I have found two remedies for the problem which will hopefully solve it for you as well.
Given that the issue only occurs when certain monitors are connected, I concluded that the root of it must be a bug in the Mac's firmware related to DDC (Display Data Channel) handling, and that the most promising way to address it should be to just disable the DDC.
Workaround #1: If your monitor has BNC connectors, use a VGA to BNC cable.
In this configuration the DDC pins are not connected to the monitor at all. This did indeed fix the problem - my Mac mini booted without a problem with the monitor connected. However, I was not completely satisfied with this solution, because VGA to BNC cables are usually quite heavy and inflexible, and do no go together well with Apple's MDP to VGA adapter and the Mini Displayport/Thunderbolt port which has no locking mechanism.
Workaround #2: Remove pin 12 of the VGA plug.
Pin 12 of the VGA plug connects the serial data line of the DDC. Pulling out this pin with a pair of needle nose pliers will effectively disable DDC. I hesitated to do this to my cable (a direct MDP to VGA cable which eliminates the need for a separate adapter dangling from the Mac) and therefore bought a tiny VGA male to female adapter (also called port saver, e.g. Delock 65250) to perform the surgery on that. This has done the trick and my Mac mini has started up fine ever since.
Of course, without DDC the Mac won't know the model name and capabilities of the attached monitor and thus offer some resolution and frequency settings which the monitor may not support, but that's a small drawback compared to having to pull out the monitor cable everytime you turn on or restart your Mac.

HDMI Monitor flickers

I have an VGA Monitor connected via adaptor to the HDMI port as a second Monitor to my Thunderbolt display. The VGA Monitor flickers and it was suggested to upgrade the firmware. But the system tells me the firmware is not for my system (Mac mini Model A1347 from autumn 2011).
How can I fix this problem?

What monitor(s)...?
If one has (Digital) DVI input, then you should use it on the HDMI port with the Apple Supplied HDMI to DVI adapter and a good DVI cable.
If both have (Digital) DVI input, then it would be best if the second one was also on a Thunderbolt/MiniDisplay Port to DVI adapter instead of analog VGA.

Connecting to VGA monitor

I need to connect a new mac mini to a vga monitor. Where can I get an adaptor? The mini comes with the HDMI to DVD-D adaptor. I am having trouble finding a DVI-D to VGA connector. Please help! I gather there is nothing yet for the Thunderbolt port.
Thank you in advance for your help,
Norm

Yes, the mini display port and thunderbolt port are one in the same.
I have my mini hooked up to one. The resolution isnt the best but I only use it for a media server.

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.

How can I connect a new mac mini to my old vga monitor? There doesn't seem to be a mini display port

I have an old monitor with VGA port, and was wondering if anyone knows how to connect this to the new mac mini. Older mac minis have the mini display port, and if that were the case I would use the mini display port to VGA adapter, but this new mac mini doesn't have one. It just has the thunderbolt port or HDMI port for displays... I've been looking for an adapter to connect my display to one of these but cannot seem to figure it out. Any advice? Thanks in advance.

The Thunderbolt port is the one to use; you use the same mini-DisplayPort adapter you used for the older minis.
Regards.
