VGA cable external monitor

I have a 2010 27 iMac and an external 22 inch Viewsonic monitor.
1. The monitor and VGA cable are about 5 years old.
2. I have the correct mini display port to VGA adaptor from Apple.
3. The external monitor works, however, it works only after I try to turn it on 5 to 25 times.
Aggravating in the extreme.
Could this be a problem with a low-quality or old VGA cable?
Would a brand new (higher quality, if so what kind) VGA cable?
I read this could be a problem with a video card, but I presume my 2010 iMac has a good card.
In short, would a new VGA cable likely solve the problem?
Thanks.

Hi, Lil,
   What is the downside in connecting the monitor with DVI? Digital is better than analog for image quality anyway.
    That being said, I have tried VGA from my dock in the past, with no odd symptoms such as the ones you are describing. You certainly don't want to get stuck with a defective dock. Are you using the same cable to attach the monitor whether it be to the dock or direct?
                                                                        ZZ

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.

Does digital vga cable link from ipad2 to external monitor work with pages and numbers

Are you able toutilize pages and numbers on an external monitor with and ipad2 by utilizing a digital VGA cable

Hi ederg:
You may want to download/update: Monitor file for Windows 7 (Thinkpad)
The reason I say that is because the readme it states, "If you use the preload environment, you do not need this package. This package is required when you install Windows OS without the preload image."
Since you setup the Thinkpad with Windows 7 Pro CD and no longer have the preload image, this may fix the problem.
Also, have you checked the website for the displayport manufacturer? They may have updated drivers there that wouldn't have been on the update tool you used.
*Edit* You can also check the: External monitors issues section here. It goes over some basic troubleshooting you may want to try first (I just came across it now)
Let us know how it turns out!

Mini Displayport to vga adapter on MacBook pro 13" late 2011. No signal on external monitor

Hi
Connecting a Late 2011 MacBook Pro 13" to an external monitor, trough mini Dispalyport to vga adapter, i see "no signal" messagge on external monitor, even if i get it as secondary monitor on Preferences > Monitor of my MacBook it's visible (i can change resolution, position, clone screen, ecc.).
Any suggestion? somebody found the same problem?

Hi
i did what you said and tried with other resolution/refresh rate combinations, also with anoter external monitor (and vga cable) but its still the same: monitor is detected but there's no signal.
Now I will try to chek if the adapter works on other pc and monitor.
Thanks
(anyway it was the firs time i connect this mac to an external monitor)

Possibly mundane Mini-DVI to VGA into an external monitor problem

Hi,
I've had a look over the interwebs regarding my problem and it seems as if it's not unusual to have external monitor problems but I'm not sure if mine is slightly different:
I had a perfectly working set up with my new Macbook (the white one, '06 model I believe), that was connected to my Hanns-G HU196D monitor via a mini-DVI to VGA adapter, no problems whatsoever. But for a couple of weeks now my Macbook just flickers a light blue colour, with nothing at all on the monitor, and my macbook is unusable until I remove the adapter. I've read about updating firmware but I can't see my desktop once the macbook is connected to the monitor so it's not possible to configure anything. I've read somewhere that my external monitor isn't compatible with this set up, but it was until a couple of weeks ago!
My Macbook's 4 months old now and since then I've bought a new mini-dvi to vga adapter and a new VGA cable, no connections seem loose on either mini-dvi port or my monitor's vga port.
Thanks if you can help!

You will need to use a mini Dvi-dvi and a dvi-svideo/rca adapter.
Joy joy hallelujah.
Pardon the sarcasm...I just wasted 3 hours of my life trying to sort the issue out.
Heard a KWORLD PlusTV PCTOTV Converter SA235 USB 2.0 Interface would sort the issue out for under 40$ but it's not Mac.
Hope that helps.

Mini DVI to external monitor (VGA) problem/firmware update does nothing

Hi,
Four months ago I bought a new white 13-inch Macbook (2006 model I believe) along with a handy mini-DVI - VGA adapter. I used a Hanns-G HU196D external monitor which worked fine for a couple of months but then stopped, and had the same problem with a (much cheaper) 'LiteView' monitor. I find it bizarre how they work absolutely fine and then stop, with no damage to the adapter, cable or ports. I've since bought a new adapter and cables + trying out a different monitor and still the same problem...
I've installed a firmware update that describes the exact symptoms, but it's done nothing. Can anyone help me resolve my issue?? It's still under warranty so is it an unusual problem that'll need to be fixed by Apple?
Thanks

Are you using the mini DVI to DVI followed by a DVI to VGA adapter? That may not work if the mini DVI to DVI adapter does not pass analog video. If that is the case, you need the mini DVI to VGA adapter:

2013 27" iMac using mini displayport to VGA, external monitor off center.

I recently purchased a new 2013 iMac 3.5 i7 and connected two external monitors. The minidisplayport to DVI adaptor works fine on one monitor but the minidisplayport to VGA is off center on the 2nd monitor. There is a 2" black band on the left side of the screen. I've replaced the adaptor, cable and tried on two different monitors. I've also tried repositioning image in the monitor settings which it can't move far enough. It only happens on 1920 x 1024. Any other resolution is fine. Other than that it works fine, but this space is going to drive me nuts. Because these are 23" monitors I really would like the highest resolution possible. I'm stuck. Any thoughts?

Update: I switched to DVI and it worked perfectly. I guess there could be an issue with the mini displayport to vga adaptor on the 2013 iMac. I also tested it on a 2012 mac mini and the vga operated as it should.

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.

When i connect my mac book pro to an external display using a VGA cable and adaptor, the external display splits into several different columns of the same screen overlapping one another. Does anybody have any ideas as to why this happens?

I have used different VGA to mini port adaptors, different VGA cables and connected them to different external monitors and prjectors but the same thing happens. I am starting to think there may be a problem with the macbook itself however, when i have used a HDMI lead and adaptor to external monitors the external display is fine.

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).

Which cable to use for 2 external monitors on MacBook Pro?

Hy there,
I'm currently using one external monitor on my MacBook Pro via a mini display to VGA cable from apple.
I would like to hook up another (second external monitor) one using also VGA.
After doing some research I've learned that I should use some sort of adaptor cable for this. I'm just wondering if there is any way of getting one of there for a decent price in europe? (decent is sub €100).
Thanks a lot!

HT3131 how can i connect 2 external monitors(VGA) to my 2007 macbook pro

I would like to use 2 external monitors simultaneously with my clamshell closed. I have external keyboard and mouse but need to know how to and what to buy in order to achieve this.....havent found anything straight forward on apple site, like a vga dual monitor splitter, so am in need of some advice on how to do this please!

Thanks for the reply. Haven't gotten anything as yet. Just that I burned out my older PowerBook using it as a primary screen w/ a secondary 20" monitor. Would be nice if the MacBooks could be used as a CPU only, connect 2 different monitors, and use the LCD screen when portability is needed. But I suppose that is why Apple makes different types of computers. I know I can rig the video SCSI cable to bypass to LCD screen and use the other built-in monitor. But there goes the warentee and any kind of AppleCare... not that I have ever used it, (until a day after it has expired!)
But thanks for the feedback. Your reply is what I expected. Being that I am a mercenary graphic designer and need to be able to work whenever, and where-ever I need to, the MacPro is not my hardware of choice. As well, I don't have $4000 in my budget. But man do those machines rock! Just think of what NASA could have done with one of those in 1969 when we were going to the moon! But now that the U.S. has decided that manned space travel and even scientific space exploration is not worthy of having a budget, the MacPros are religated to creating new episodes of Jersey Shores!
Thanks again for your feedback!

T500 XP 32 - 2 external monitors - one in VGA-out & one in DisplayPort ? (1920x1080 & 1280x1024)

I searched and found some information... but the information wasn't specifically clear, so better to find out for sure, and help archive some clear information for the community...
I'm looking at attaching 2 external LCD monitors to my T500 (2082-3HU). OS is XP 32bit.
One will be a 19" 1280x1024,    and the other will be a 27" 1920x1080.
Plan is to connect 1 to the VGA-out and 1 to the DisplayPort.
First.. will this work?
Second.. which is better to attach to which port? (and why?
and
Third.. what are the maximum resolutions that the VGA and DIsplayport ports can provide?   Does it matter if it's VGA or DVI?
I was going to get a USB to video adapter for $50+, and then remembered the DisplayPort!    If it will work, it's a great way to save some money, get much better video res. and speed, and keep a USB port free.

Here are two posts I found ... (they appeared out of no-where)
you can connect two external WUXGA (1920x1200) monitors to the T500 using both the VGA and displayport connectors.   no other hardware is needed besides the display cables.

I connected 2 external monitors (1 thru Displayport , 1 thru VGA port ), and it works fine, its very easy to configure it using Lenovo Presentation utility.

and for any more monitors, a USB-VGA, or USB-DVI adapter can be used... from lenovo, or EVGA or any other good type.
DisplayPort can support, at least, 2500x1600

use a Lenovo usb2dvi converter and the displayport to dvi converter.
This will allow you to use 2 external WUXGA monitor. If you need to support more WUXGA monitors, then you just need to get more Lenovo usb2dvi converter, up to a maximum of 6 (maybe slightly less i can't remember) using the integrated gpu.

VGA external monitor shows yellow and green colour

I just took apart my T410s to change the screen hinges. I thought all had gone well but when I plug in an external monitor the colours don't display properly. The display is yellow and if you wiggle the cable it goes green. Could this have been something I did? It worked fine before.
Any ideas how to fix it?
Thanks
Andy

Hi, arp1981
I have a question for clarification: Does this only occur on an external monitor, not the laptop's display itself? If so, then I would retrace your steps of replacing the hinges and make sure that all wires and devices are where they should be. Also, check the pins on the VGA cord and the VGA port itself and make sure nothing is bent.
Best,
Adam

IPad 1 - VGA cable not outputting to projector, monitor or TV?

I recently purchased the apple VGA cable so that i could project powerpoint presentations using my iPad 1. I have no success at all using any applications to make this work. Slideshark, Keynote etc.
I had read that only video streaming is supported, however, i cannot get Youtube or any other content to show up. The cable works fine with my iPhone 4S.
Is there a setting I need to adjust on my iPad? When I plug it into a computer monitor, projector, or TV it seems to detect a signal but the screen stays black.
Any help would be very much appreciated.
Aleks

Thanks all... of course after I posted the query, I decided to do a forum search and found that this was not a unique question...in fact the VGA connector for the iPad1 is about useless. I did do a Slideshow and the images DID display on the external monitor. So the system does work, albeit with some decided limitations.
Well, not a reason to get an iPad2 yet, this was an experiment and not a regular requirement for me.
Still.... an odd decision by Apple to be so selective about what it allows to clone. And while they are at it, next time around, an extended desktop option would be really, really neat.
