Thunderbolt issue vga dvi

On the new mac mini with Thunderbolt, problems with monitors like macbook.
Thunderbolt - Minidisplay to VGA - screen not activate, diferent screens.
HDMI > DVI - Eizo screen S2202W, switch from vga to dvi, screen 3 sec snow before right image.
VGA and DVI screen to mac mini, VGA screen as master.
At boot, screen DVI as startup screen, VGA black
after boot both screen black and then image on both screens.
After disconnect vga screen
Both screen setup in one screen.
Are there users with the same problems.

There do seem to be a lot of people having problems (possibly everyone trying to use a VGA monitor) on the new Mac mini.
If you can you should use DVI or HDMI, however if you have to use VGA it seems that turning the Mac on waiting for it to finish booting and only then connecting the Mini Displayport to VGA adaptor works.

HT4617 Even though thunderbolt is not hot puggable in Bootcamp, is the use of mini displayport to vga/dvi still hot pluggable under Bootcamp?

This is Apple support on the subject

Can I plug and unplug devices into a Thunderbolt peripheral that is already recognized?
Yes. That is the best way to add and remove devices from the Thunderbolt chain while Windows 7 is running.
Have you tried?

Strange issue with external monitor, only working when external speakers plugged in (using Thunderbolt to VGA adaptor)

Hey – I am having a very strange issue with my external monitor; where it only works if my external speakers are plugged in and connected.
I am using a late 2011 Macbook pro, running Mavericks 10.9.4, along with an MBox 2 (USB Audio Interface), and two powered speakers (KRK Rokit 5). This setup has had no issues. I have just acquired an external monitor (Benq T2200HD), which I am using with a thunderbolt to VGA adaptor (a cheap Chinese knockoff adaptor).
To start - I plugged the monitor in with the thunderbolt adaptor, and it powers up and works fine. However, there is a nasty buzz coming from the speakers. I did some research and it looks like a simple ground loop issue. I did a bit of troubleshooting, and this is where things get weird.
What I found is - If I unplug the MBox, the monitor loses signal from the computer (displaying ‘No Signal Detected!’). Further, if I keep the MBox plugged in, however unplug both the cables from the MBox to the speakers, the monitor loses signal. It doesn’t matter if the speakers are turned off, however they need to be plugged in (or the monitor loses signal). Weirder still, I can unplug the MBox, however the monitor will work if I plug in the speakers through my macs headphone jack.
Simply put, the monitor only works if there is a direct connection between the computer, the speakers, and the power source. What is going on here? Is the monitor grounding through the computer port, to the speakers (I don’t know how this works, is this possible?). Could it somehow be the cheap VGA adaptor I am using?
Some other information:
- Everything is plugged into the same multi-box for power. I have tried plugging things into separate sources, and the result is the same.
- If I unplug the thunderbolt adaptor, then the speaker noise disappears straight away.
- The ground noise doesn’t appear in my headphones, which are plugged into the MBox.
Any information would be great – am I missing something here, or is this genuinely weird?

Well, I went back into Best Buy to test on 3 other laptops (2 Asus, and their floor model for this Sony). It seems to be doing the same problem so at least I was able to rule out broken hardware issue on my particular laptop.
Here's what I did to test:
Since I couldn't really install Adobe Premiere on their machines, I used the DVIO software (http://www.carr-engineering.com/dvio.htm) and a 5 min clip I captured. I transferred onto their machines, hooked up my Sony D8, and attempted to play the video. It would play for 15 seconds and then stop and jitter with a loud noise (like it does on my laptop). I even tried changing each machine's firewire driver to the legacy one and same results. I pulled a brand new 4 pin to 4 pin firewire cable off their shelf and still the same problem.
I think I've nailed it down to Win7x64 bit Home Edition not playing nice with Firewire driver. Very annoying. I can't find any concrete evidence of this from other users on any of the forums that have my particular problem, but from my own testing, it's all I can conclude.
I have 2 other things I can try:
1. Opening the laptop and looking at the firewire to maybe find appropriate driver (ugh, I don't want to have to open this thing up).
2. Upgrading to Win7x64bit Pro and possibly testing with XP on the new MS Virtual PC (http://www.microsoft.com/windows/virtual-pc/). I can't do it with my Home edition apparantly.
Who needs to view video on an external TV anyways....sheeesh...(scarcasm).

Thunderbolt to VGA and and HDMI to DVI running at once

I am currently using a Thunderbolt to vga converter to as my setup for my mac mini. I just remembered that with the mac mini came a HDMI to DVI converter. My question is; if i buy an other monitor, can i use the HDMI to DVI converter to run two monitor at once?
Thanks in advance.

Yes. You can use to monitors on a Mac Mini. You can select to have them mirror one another or at an extended screen/desktop.

I am considering a Apple iMac but would be interested in adding a second monitor. Does it have to be an Apple monitor or can i add any monitor with a thunderbolt cable and DVI or vGA adapter?

I found that the Thunderbolt input accepts the mini-DVI (in my case converter to VGA for a tutorial use monitor)
BUT, you have to really oush it in 'til it clicks. I thought it too loose until I tried it. works just fine!!
i get a solved for my own LOL

Thunderbolt to VGA adapter issues

Hi guys,
I have bought a THUNDERBOLT TO VGA adapter to duplicate my screen on my TV, but when i plug in it my TV doesn't show anything. It shows just "Control signal", but I don't know how fix this problem.
Could you help me?
Thank you !

I have this same problem, discovered today in front of customers, when hooking up to their VGA projector. The VGA adaptor did not work very well with OSX either so running Windows under Parallels did not work either. Back in the office, I experimented with our old VGA projector, same problem, but I could get OSX to display and thus Parallels. Back on the Win 7 bootcamp, resolution is grayed out and set to 640x480, too small to do anything. I tried another sugestion of updating the Nvidia driver in Windows, to the latest version but that did not help. The only other suggestion that worked for others is to get a USB3 to VGA adaptor. Aparently Apple needs to update their bootcamp drivers for the mini display/thunderbolt port. So until that happens, perhaps the USB3 adaptor will be the way to go. I'm going to order one now since I cannot find it in the local apple stores or Best Buy.

Asus vh232h out of range, Mac mini thunderbolt to vga

Hey guys,
Pretty much what the title says.....
Mac mini
Asus vh232h (VGA only, no dvi socket)
Thunderbolt to VGA adapter
VGA cable (I've tried several)
(Benq monitor running fine on the hdmi port)
In short, if I use a VGA cable under 1.8m, there's no problem.
If I use a cable of 3m in length, or two x 1.8m cables, I get a "Out of range" message on the monitor.
(My office is shared space, so I need the Mac mini to be inside a lockable cupboard. That means I need a cable longer than 1.8m)
FYI, I don't seem to be able to set the asus monitor resolution in Mac settings (not sure if it can be done when monitor is 'out of range', but I can see the Asus in Display settings, Arrangement. It looks about half the width and height of the benq.
Is a monitor supposed to connect successfully over a 3 m cable?
Will a thunderbolt to dvi adapter work? (Would have to buy new monitor)
Any other ideas?
Thanks,
Darren

Bought a new benq 24" monitor, moshi mini display port to hdmi adapter, and 5m hdmi cable.
Sorted.
Must be an issue with apple mdp to VGA adapter when using VGA cables over 1.8m long.

Can I use a VGA/DVI-D monitor to a new 2014 Mac Mini?

My wife's PC just died (it was a cheap 300 pc that lasted probably 5 years.
She basically emails, web surfs, looks at pictures and plays candy crush on Facebook so she doesn't need anything too high end.
I was thinking of getting her the basic 2014 mac mini but I have a VGA/DVI-D monitor (an older Dell) and it fits perfectly on her desk.
Can I somehow hook up a new mac mini to either the DVI-D or VGA input?
If not, what is the best monitor to get HDMI or should I look into a thunderbolt monitor?
Thanks,

Yes. You will have to purchase one of the following adopter:
- HDMI to DVI and use the Minis HDMI output
- Mini displayport to DVI adopter and use one of the Minis Thunderbolt ports
- Mini displayport to VGA adopter and use one of the Minis Thunderbolt ports
I would use the monitor's DVI input over the VGA input

Is it possible to connect a mac book pro via thunderbolt and a dvi switchbox (multiple computers) to a thunderbolt display?

Hi,
I'm planning to buy a thunderbolt display.Since I have not only apple computers with a thunderbolt port I wonder if it's possible to connect my mac book pro via thunderbolt and a DVI switchbox via a "mini displayport to DVI connector" to the thunderbolt display at the same time. Thunderbolt is a bus architecture. Thus there must be an ingoing and an outgoing port on the display. The rearview of the display I've seen so far don't show this:
If this is not possible then I must question the market chances of this product. Seems as if the product marketing guys exaggerated the launch of the thunderbolt technology.

How to connect windows laptop (vga) to thunderbolt display?
AHHH??!!!!!! Was that your original question?? I assumed you were trying to output FROM your computer (MacBook Pro w/ Thunderbolt) to the new display and then OUT to be the video source to a DVI switcher.
MB Pro w/TB ---> TB Display ---> mDP-to-DVI adapter ---> DVI switcher
So it seems as if it's not possible to use the thunderbolt display with the mini display port adapter to DVI you've mentioned.
I did not understand that you were trying to use other PC's into a switcher and then THAT Video source to connect INTO the TB display. If THAT is what you're trying to do, then NO.... You can NOT use the new TB Display to be used to display "FROM" a DVI switcher (and also can NOT be used to display from other Non-TB-Apple computers).
I've also called apple. The statement was that one needs a computer with osx 10.6.x in order to connect the thunderbolt display. That makes it impossible to hook a windows pc or older mac to the new and shiny thunderbolt display.
I wonder why apple doesn't state this in their technical descriptions...?
-ais-swiss
Actually, the state that information all over the Tech Specs on the Apple Store website.
http://store.apple.com/us/product/MC914LL/A?mco=MTY3ODQ5OTY
Here are two different statements from that webpage:
So yes.... other NON-Apple PC's (or non-TB devices) do Not have the Thunderbolt technology (hardware/software) to be able to communicate with the TB display or other TB devices.

Thunderbolt to VGA problems.

Folks, I just setup two Mac Pro computers (late 2013 cylindrical model) and am having problems on both with Thunderbolt to VGA adapters. I get a line at the top of the screen that flickers at a constant rhythm of sorts and the desktop doesn't fill the screen. In fact the dock is pushed a little down beyond the edge of the screen.
I have two 24" monitors plugged into both computers. There's no problem with anything plugged in via DVI or HDMI, but it does affect these two brand new out of the box Samsung and HP monitors connected via Thunderbolt to VGA adapters.
I found this link and firmware to try and remedy the problem, but when run it just said it couldn't find a supported MiniDisplay Port to VGA adapter.
Any ideas folks?

I suspect that the firmware is only applicable to one specific brand of adopter.
I have used Apple mini displayport to VGA adopter on my 2013 Mac Pro without problems for 1080p like your HP monitor.
I suspect a problem with the adopter. However, try resetting the SMC and PRAM
Intel-based Macs: Resetting the System Management Controller (SMC)
About NVRAM and PRAM
otherwise try another brand adopter. I would try min displayport to either HDMI or DVI if you can get them and get the right cable

VGA/DVI cable - wanting to use two monitors.

I got a VGA/DVI cable to connect the VGA port on my LCD TV to the DVI port on my desktop computer. I'm trying to use 2 monitors on my computer which has both a VGA and DVI port. My regular monitor was already on, and the computer detected the TV as a monitor but the TV wouldn't detect a signal. I had the TV on the VGA/PC setting. The cable was a return item so it might be defective. I was wondering if there's anything else I could try to get it to work?

My computer's DVI port doesn't allow for the contacts above and below the flat blade like the DVI-I and DVI-A connectors in the picture. The cable that I got does have those contacts.
Ooooooh. So your computer may be one of the rare animals that doesn't have a DVI-I output, only DVI-D.
Since your TV has HDMI inputs, this is the way to go. Get a DVI-to-HDMI cable. It will provide higher quality than VGA and is USUALLY easier to use, I've never had video timing/resolution support issues with HDMI. (However, every computer I own has an Nvidia graphics card - the story may be different for ATI or Intel graphics!)

Thunderbolt to VGA adapter in bootcamp only 640x480?

Just a few weeks ago I purchased a new MBP Retina for my new work laptop. I contantly go from Windows, to OS X to demo hardware to customers. Problem I am having, is that as soon as I connect the Thunderbolt to VGA adapter in Bootcamp on Windows7, it forces 640x480 and I dont get the option to change. The adapter runs fine in OS X.
Has any one else ran into thise issue? Pushing VGA in Windows is something I need to be able to do.
Also noticed that in OS X, I dont have the option of running 1280x800 as a resolution. Is there anyway to configure either the adapter or OS X to push this oddball resolutuon for our office projectors?
Thanks
Charles

I have a imac 2308. where can I find a thunderbolt to VGA adapter to add additional monitors

I am trying to attempt to add two additional dell monitors (vga) to my EMC2308 imac. I only have one thunderbolt port and have not had luck finding a thunderbolt to vga adapter. Any ideas?

A notable peculiarity of Thunderbolt is that it uses exactly the same connector as Mini Display Port, and that's not all. The Thunderbolt connector also carries Mini Display Port video signals. That means you can plug a Mini Display Port video cable/adapter in to a Thunderbolt connector and your monitor will work.
If you plan to do other things with your Thunderbolt connector and don't want it wasted on a monitor, you can also choose an HDMI --> DVI adapter, which for your purposes will be functionally equivalent.
You can even use both at the same time.

Can i connect a Samsung VGA/DVI monitor to macbook air?

I am looking to buy a Macbook air (13.3 inch). Is there a cable available to connect the Macbook air to my old monitor (Samsung that only supports VGA and DVI)? Eventually, I will buy a Thunderbolt display, but can't afford that yet.
Thanks,

Certainly you can. Just about any Apple retailer will have a Thunderbolt/MDP-VGA or Thunderbolt/MDP-DVI adapter. Apple has them also available through the online Apple Store.

Is every external monitor compatible with mac via a thunderbolt to vga cable

Is every external monitor compatible with macbook air via thunderbolt to vga??????/

Yes if the monitor has a VGA D-Sub input port.
Otherwise you'll need a TB to Whatever The Input of The Monitor Is adapter. Could be DVI or HDMI.
