Hi,
DVI if for digital and VGA is for analog. You definitely need a converter.

Connect to Dual-Link DVI-D port on monitor using DVI-D to VGA adapter -- getting no signal

I have a T400. I am trying to connect to a dual-link DVI-D port on my LG monitor via the VGA port on my T400 laptop. I bought a DVI-D to VGA adapter, but I am getting no signal.
Do I need some other method or adapter or cable? Monitor works fine for VGA to VGA connection.
Solved!
Go to Solution.

I happened onto this thread while searching for a way to connect my T400 to my wife's 27" iMac. What I learned thus far is that Atlona makes a device (AT-DP400) that will convert dual link DVI to Mini DisplayPort. But Atlona says that one's graphic card must support 2560x1440. The T400 doesn't have a DVI out (nor does my current docking station), but it sounds like one can get a docking station that does. But that won't help if my card won't support 2560x1440. So are you saying that there is no way I will be able to use the 27" iMac as a monitor for the T400?

HDMI/DVI adaptor to VGA on Monitor - No Picture

Same with Thunderbolt/DVI adaptor to VGA on monitor. Is it the adaptor to DVI/VGA cord that is making the problem?
System Information sees the Monitor(Sony Bravia TV)
Display Preferences sees my dual display set up
The computer acts as if I have two screens running
But no picture on the monitor with the signal path described above

Welcome to the wonderful world of copy protection.
Your display may not be on the "approved" list, or was removed from it.
Apple's newer Mac lines include a form of digital copy protection that will prevent protected media, such as DRM-infused iTunes movies, from playing back on devices that aren't compliant with the new priority protection measures.
The Intel-developed technology is called High-bandwidth Digital Content Protection (HDCP) and aims to prevent copying of digital audio and video content as it travels across a variety of display connectors, even if such copying is not in violation of fair use laws.
Apple has apparently acquired a license for the technology and is now using it across its lines to to prevent transmission of purchased iTunes content to devices that don't include support for HDCP.
The problem can often be solved by using an HDMI to Component Video adapter. Many believe that Component Video will give you a better picture than HDMI without any of the hassles of HDCP.

DVI-D-to-VGA vs. Straight DVI-D Cable?

Hi. Apologies if I missed this question elsewhere.
I'm using the included DVI-D-to-VGA converter to connect to an LG monitor. Next I want to share this monitor with a second, similar Mac (PowerBook), so I'll be getting a KVM switch.
My monitor supports both VGA and DVI-D. Is there any difference between using VGA and using straight DVI-D connections? Everything seems fine using VGA, and there are a lot more options out there for VGA KVM switches than DVI-D based one, but I'll go straight DVI-D if I'll gain something substantial in doing so.
Any thoughts?

VGA is usually quite acceptable up to resolutions of 1400 and possibly 1600. If you're using extension cables, they need to be high quality to reduce ghosting and other issues. Some KVMs may limit your max resolution, so be aware of that if using a large monitor.
VGA can suffer from ghosting, especially with cheap cables or cheap KVMs. (Cheap KVMs use cheap cabling.) In one case, I had to reduce my resolution to 1024x768 due to ghosting by the KVM. But all the good quality KVMs I've used work well with VGA up to the 1280 or 1440 resolution range. If you need higher resolution than that, VGA KVMs may start having issues. Meaning, you need higher quality (a.k.a. more expensive) KVM. Some KVMs will go to 1900 resolution, but of course, tend not to be cheap. But by that point is when you'll want to look at DVI KVMs, which tend to be significantly more expensive than comparable VGA KVMs, but being digital, don't suffer from ghosting at those high resolutions.
Short answer: don't go cheap unless you're only going to be using small monitors at 1024 or less.
Edit: since your monitor supports both DVI and VGA, if switching the input at the monitor is not too inconvenient, then perhaps just plug both computers into the monitor and make a "poor-man's-KVM." Since one of the computers is a Macbook, you don't really need to switch the keyboard through the KVM, unless you're using the Macbook in clamshell mode.

Concerning: VGA monitors using an Aluminum Powerbook G4 PowerPC 2004 15"-screen 1.5Ghz
The DVI (converted to VGA) video output stopped working on this computer after 9 years of service. This raises question 1:
Is there any way of fixing this? I've tried the usual: triple checked all vga cables & devices through trial & error. Bought a new DVI-VGA adapter. Reset PRAM, PMU, etc. Nothing works. Something is probably damaged, because my KVM switch was not working unless I hot-reseated the vga cable into it, leading to this DVI port, and that is pretty rough stuff.
Question 2 (related):
This dovetails into this: Can I drive a VGA monitor with the s-video output port on this computer. It would take an s-video (male)-to-15-pin-VGA adapter. Has anyone does this? So far, I haven't even found the adapter mentioned anywhere.
Thanks for reading this.

Thanks for the useful feedback, Knucklesmac. I agree. I must have blown something on the logic board -- because I had a faulty old KVM switch that would not switch between computers without some nasty hot-plugging/unplugging the VGA video cables. (wince!). It's like when Dizzy Dean ruined his arm because a line drive hit him in the foot and he readjusted his mechanics around the injury. I take the blame because this has been a great computer, and does not deserve any blame.
If it will help anyone else reading this thread, C2G (née Cables to Go) has some interesting ideas for still getting external video out of this computer:
-USB-to-VGA
http://www.cablestogo.com/product/30545
-Convert s-video or composite video signals to high resolution VGA
http://www.cablestogo.com/product/40971
The price range is $75-$85, which doesn't make horse sense to me for such an old computer -- which has a lot of life in it anyway, because its own 15" monitor is not chopped liver.

Mini HDMI-DVI disconnects when vga thunderbolt adapter is removed

What I have found is that if the vga and HDMI adapters are connected to a monitor, I can get a signal from the HDMI-DVI adapter. But when I disconnect the vga adapter, the HDMI-DVI signal goes away too. Anybody know what's going on here?

As other threads on this have pointed to, Monoprice sells HDMI/mini-displayport to VGA cables.
http://www.monoprice.com/products/product.asp?c_id=102&cp_id=11215&cs_id=1024605 &p_id=6004&seq=1&format=2
Given the minor price variations, why not get a 10'?
It's very annoying that Apple's included adapters are DVI-D not -I, otherwise I could use those DVI-I to VGA adapters that seem to litter my clients spaces....

Split DVI - I to 'DVI - D and VGA' to connect beamer(vga) and 24"(DVI)

Is a mini dvi the same as a mini display/thunderbolt which my new mac mini has?
The monitor is a vga only.

You'll need a > Mini DisplayPort to VGA Adapter - Apple Store (U.S.) for a VGA monitor.

Mini-DVI does not work with DVI anymore only VGA output

Hi,
I recently started to get problems with external LCDs. It used to work just fine, but now I can only use a mini-DVI-VGA adapter to get any output. This gives me much worse results than digital and makesme a little worried, other things might also stop s
working.
A quick search here and on google didn't give me any ideas how to fix this.
So any help is much appreciated!
Cheers
GerHi

Have you tried a new DVI adapter?

Going from DVI to DVI cable from VGA to DVI cable problem

Got a mini with the VGA adapter to DVI working with no problem. When I decided to hook up a DVI to DVI cable, I got no picture. I had to reach behind the mini, press the power button to put it to sleep, then press the power button again to wake up the mini again to get a picture. The monitor is a 20.1 inch AOC monitor. The picture is sharp in both cases. The DVI to DVI setup is slightly smoother.

After I reboot I still get no picture. I have to reach behind the mini, press the power button to put it to sleep, then press the power button again to wake up the mini again to get a picture.

HP 2310ei Monitor (DP/DVI-D) to VGA/HDMI laptop

So, I recently bought the HP 2310ei Monitor. It has DisplayPort and DVI-D connections.
Originally I had planned to just use a VGA/DVI adapter, but I didn't realise that there's a difference between DVI-I and DVI-D. Now I'm wondering, whats my best option?
Buy a Vga to DVI-D adapter? Or a Vga to DisplayPort?
Or maybe go with HDMI to DisplayPort?
On the official DisplayPort website I read that there is no efficient way to connect a VGA Laptop to a DisplayPort monitor because of Analog/Digital, whatever that means, but in a different topic on this bord I also read that someone who bought a HDMI to DisplayPort cable couldnt get it working, so I'm kinda at a loss.
What are my best options?
This question was solved.

When requesting assistance, please provide the complete model name and/or product number of the computer that is being connected to this monitor.
There isn't a VGA to DVI-D adapter nor a VGA to DisplayPort adapter on the market, however there may be some expensive active convertors. Depending on your exact computer and its video output ports, you may have a few options. Being that you also ask about going from HDMI to DisplayPort, one can assume your computer has an HDMI out. If this is the case... the easiest, cheapest, and way to connect an HDMI output to the HP 2310ei is with an HDMI-to-DVI cable.
If you have any further questions, please don't hesitate to ask.

DVI.I to VGA LCD monitor

Hi Everyone
Is there anything to gain by using the DVI connection on my MSI FX5900XT graphics card
to the VGA port on a DELL 19" LCD Monitor ?
I was just wondering as the card came with an adaptor DVI/VGA so I can use either output on the card.
At the moment I am connected VGA to VGA
cheers

Apple didn't ship a 2.4GHz MacBook until February of 2008. If that's the model you have, or an earlier model, it has a mini-DVI port which would take the mini-DVI to VGA adapter. To confirm, run System Profiler, click on the Hardware heading at the very top of the left-side list, and tell us what the Model Identifier reports.
Regards.

DVI-I to DVI-I and VGA Adapter work with Apple?

http://www.extron.com/product/product.aspx?id=dvihdmiadapters#features
This is an Extron product. I have a need to go from a Radion 9800 pro DVI-I to an apple 20" Cinema AND 32' LCD VGA.
Will this work with Apple?

Hi There,
Whenever I hook up a projector that doesn't work with my MacBook (when it shows just a blank, black screen), the first thing I try is going to System Preferences > Displays and setting the resolution of my desktop to 800x600.
Nine times out of ten, the projector starts right up and works perfectly.

DVI vs. VGA

hi all,
I have two G4 Macs connected via KVM (VGA) switch box. Both Macs have 64MB video cards with DVI/VGA capabilities. Will I see a better visual difference if I were to buy and connect a DVI monitor over a VGA monitor?
Thanks
Web dude

Something is not quite right here. I have MDD dual 1.25 GHz with upgrade video card, and it's quite happy with 1680x1050 resolution of 22 inch LCD monitor using VGA connector thru KVM switch. I did try DVI cable and saw no difference. Connected to second KVM VGA port is 500 MHz G4 AGP running OS 9.0.4. This one has to be tricked into hi-res display. I start it up with KVM switched to other computer and can then select 1600x1024 resolution which it will remember unless computer crashes and has to be restarted. As long as G4 AGP is started with no monitor, it will offer the 1600x1024 resolution as a choice, and you can get back to it.
The stock MDD video card also does 1680x1050 on VGA, and I didn't gain much by buying better video card except for compliance with Apple's new video standards.
1680x1050 on a 22 inch monitor is not a real high-resolution display (dot pitch 0.282 mm). Perhaps Apple's and other 20 inch monitors with same resolution (0.258 mm dot pitch) give different results between VGA and DVI. Curiously, I have yet to find any LCD monitors offering 0.224 mm dot pitch like this hi-rez 15" G4 laptop (1440x960) which is also standard on the new 15" MacBook Pro laptops.

New monitor not recieving signal via DVI, ok via VGA

Hello,
I have one of the original minis (1.25 GHz, 512 MB, etc) purchased back in early 2005. Until now I've been using an old CRT display connected via VGA. This past weekend I purchased a new 20" AOC LCD monitor from Costco. I attached it with the supplied VGA cable and it worked great. The next day I picked up a DVI cable, attached it and after a minute or two the monitor found the signal and displayed a beautiful image. After five minutes the monitor lost the signal and I haven't been able to get it back since. I exchanged the DVI cable for a new one, but still can't get a pic displayed. The monitor itself is self switching. It knows if the connection is via VGA or DVI.
What am I doing wrong? Could it be the mini? The monitor?
Please help.
Thanks
Dave

Yes, it is a display specific issue. If you look at this Apple spec page for the original mini and do a search on the word "coherent" it will take you to the part of the spec that deals with the issue.
http://support.apple.com/kb/SP65
Apple displays are not a problem because they have always used coherent receivers. But any other monitor is a roll of the dice, especially with the original mini. The newer mini with GMA950 graphics appears to be much less affected by this even though Apple left the wording in this part of the spec unchanged between the original G4 mini and the current Intel ones.
