DVI - adapter - VGA to LCD w/only VGA port open

Hello All,
Have a question, I guess it would be color management related. I have 2 monitors and 2 computer systems that I use. The older system I have decided to make my photoshop system and my newer one is a gaming system. Ok on the monitors one has a DVI port, VGA, and RGB my second monitor has a DVI, VGA, HDMI all outputs on my videocards have DVI out. So do you guys see it as being detrimental if I connect my photoshop system by using a dvi-> adapter -> VGA inputs on my LCDs? Would color management and general quality suffer going with the VGA ports? I dont want to go the KVM route since it costs a lot to get a good one and dont want to have to worry about input lag when gaming. Any info is appreacated.
Thanks,
Eddie

Ok, so you have the gaming computer feeding dual monitors via dvi interfaces and you want to feed one of those monitors with another type interface as well from your Photoshop computer ?
The best and most stable image on your monitors will be achieved with a dvi connection and your monitor running at its native resolution. If you are lucky enough to have a nearly ideal vga connection between computer and monitor (again running at native resolution) then the setup should work and no impact on color management should occur. In many cases, however, the vga (analog) interfaces to digital (liquid crystal) displays can produce less than ideal results for a number of reasons. This can result in pixel jitter and/or small shifts in color. SO the advice is that if you go the vga route and you are concerned with color accuracy you must recalibrate the vga-fed monitor. Make sure the dvi-to-vga converter can handle the resolution (high analog frequency) if you have a high pixel count display.

Can I use a VGA to Mini DVI adapter for a LCD monitor for a macbook??

Hello!
First off, I love this site. Secondly, I have a macbook 10.6.6 and a LCD moniter with a VGA input. I see on the apple site there is the "Mini DisplayPort to VGA Adapter" and "Apple Mini DVI to VGA Adapter". both seem compatible but I want to pick the right one. any ideas?
Thank you!
Grant

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.

Mini dvi to dvi adapter not working with monitor

arright *** i got a mini dvi to dvi adapter which is connected to my vga monitor through a vga to dvi adapter. The computer recognizes the monitor in display preferences, but the monitor doesn't display anything it just sits in standby mode... any ideas why this isn't working? You'd think if the problem was going from vga-vga to dvi adapter-dvi to mini dvi adapter that it wouldn't even recognize the monitor but it does.
well that *****, back to best buy to get the other one. Reason i got the dvi one is because i plan on getting a different monitor with dvi soon. But noo dvi adapter wont work with vga adapters.

The mini-DVD to DVI adapter doesn't pass through the analog video signals needed for VGA, so won't work with a DVI to VGA adapter. All the control signals are there, so the display is recognized, but there will be no picture.
They could have used a DVI-D connector on the adapter, instead of DVD-I, so the DVI to VGA adapter wouldn't even plug in, but then it couldn't be used with some non-Apple LCDs, that use DVD-I connecters.

My MBP Retina doesn't allow the use of two Thunderbolt to DVI adapters. It only works with one TB - VGA adapter and one TB - DVI adapter. However now the color on the VGA connected monitor is slightly different.

The monitors are Viewsonic VA2406m-LED. The Display preferences show all three monitors but one monitor always says "No Signal" if they are both connected TB -> DVI.
The Color on the VGA connected one is slighly off. It seems like I should be able to connect two DVI monitors not sure why this is stopped. Does it have something to do with the Graphics card?

The problem was with the newEgg adapter. I just went to the Apple Store and bought an Apple adapter and the monitor now displays correctly.
For future reference, in case anyone experiences this problem:
the newEgg adapter is part number 9SIA1PU0P88920, described as a Thunderbolt Mini Displayporrt Display Port DP to DVI Adapter for APPLE Macbook Pro Air and the full description says it works for macbook pro, etc.
when this adapter is used, the macbook pro recognizes the monitor, but the monitor displays nothing.
When the apple adapter (MB507Z/B Mini Display Port to DVI Adapater) is used, the monitor displays correctly.
Of course, the individual newEgg part might simply be defective, but I doubt it. moral -- spend the extra $$ and buy the Apple adapter.

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?

Mini-Displayport to DVI adapter not working, but Mini-Displayport to VGA and Thunderbolt work fine

Mini-Displayport to DVI adapter not working, but Mini-Displayport to VGA and Thunderbolt work fine.
This is a brand new MacBook Pro (15-inch, mid-2012) just received. I suspect that this is a hardware problem as:
The mini-displayport to DVI adapter and the external monitor that I am utilizing connect and operate just fine using my older MacBook Pro (mid-2010) with the same OS.
The new MacBook Pro powers the external monitor with a mini-displayport to VGA adapater without issue.
The new MacBook Pro powers an Apple Thunderbolt display without issue.
Both MacBook Pro's are running OSX Lion 10.7.4.
The only combination which does not work is the mini-displayport to DVI adapater used in conjunction with the brand new MacBook Pro (mid-2012).
All adapters and components (mini-displayport adapters) are Apple retail adapter.
I have tried several external monitors, including my Dell U2412m.
When I connect the mini-displayport to DVI adapater to the new MacBook Pro (mid-2012), nothing happens. The external monitor reports "no signal" and attempts to go into sleep mode. Using the "Detect displays" button has no effect, even when used multiple times. Rebooting does not help, nor does resetting the SMC or PRAM.
Any other suggestions before I take it to the Genius Bar?

I turns out that the logic board of my MacBook Pro was faulty (despite being brand new).
I took it to the Apple Store, presented the problem, and one of the Tech's came to the same conclusion that I had -- hardware failure. Phone support was no help in the matter (and even told me that what I was trying to do wasn't a supported option, which is rediculous). However, the Genius Bar did take care of the problem, and my MacBook Pro was back to me with a replaced logic board within a few days.
Hope that htis helps.

Does Mini Displayport to DVI adapter support analog VGA signal?

I'm just about to buy a macbook pro. Since the MDP (mini displayport) to DVI and MDP to VGA adapters are £20 a pop, I can only afford to get one. Obviously DVI is better in general, but VGA supports more older hardware, CRTs, and the spare VGA input on one of my displays (where the desktop uses the DVI).
What I'd like to know is does the MDP to DVI adapter also support the analog VGA signal on certain pins (like most physical desktop DVI ports do)? If it does, since I have about 3 or 4 DVI to VGA adapters lying around, I can get the MDP to DVI adapter and use the DVI to VGA adapters with it if necessary, but if it doesn't I might be better off getting the MDP to VGA...

No. Unlike DVI, which in the DVI-I configuration has both digital and analog pinouts, DisplayPort (and mini-DisplayPort) are purely digital. Mini-DP to DVI then DVI to VGA will not work. If you look carefully at the Apple Mini-DisplayPort to DVI adapter, you'll notice it's a DVI-D connector - digital pins only.
The Apple mini-DisplayPort to VGA adapter contains a digital-to-analog converter.
So, you'll have to choose. If you want VGA, get Apple's mini-DisplayPort to VGA adapter.

Why aren't the VGA or DVI adapter included?

How come one of the video adapters are not included when purchasing a MacBook Pro? I would think that the Mini DisplayPort to DVI Adapter would at least be included. In previous models of the MacBook Pro a Dual-Link DVI port was on the laptop and a DVI to VGA adapter was included in the box. Now we have to pay for an adapter that should be included? And why do we need a $99 adapter for Dual-Link DVI support? This should be built into the laptop as it was before.
I just did a price compare between what our college purchased before and what will be purchased now.
On September 18th, 2008:
MacBook Pro 15-inch
2.4 GHz Processor
SuperDrive 8x
200 GB SATA HDD @ 7200 RPM
15-inch Glossy Widescreen Display
Accessory Kit (that included the Manuals, AC Power Adapter, Display polishing cloth, the install discs, a DVI to VGA converter)
4 GB 667 Mhz DDR2 SDRAM
AppleCare Protection Plan
$2,308.00
However, today, October 16th, 2008, I respeced out the laptop;
MacBook Pro 15-inch
2.4 GHz Processor
SuperDrive 8x
250GB SATA HDD @ 7200 RPM
15-inch Glossy Widescreen Display
Accessory Kit (that included the Manuals, AC Power Adapter, Display polishing cloth, and the install discs)
4 GB 1066 MHz DDR3 DSRAM
AppleCare Protection Plan
$2,318
Okay, so the memory is faster, but the price difference between the 2GB of RAM and 4GB of RAM is only $135. However when looking at the price of memory (4GB for the 2.4 GHz MacBook Pro 15-inch) on Apple's site I get $300. Correct me if I'm wrong, but I think that's the same price it was before with the earlier models. So there shouldn't be any price adjustment for the memory. The drive was also increased to 250GB but being that this is now the smallest drive size (and with falling prices on drives) there shouldn't be a price difference with this either. We also loose the DVI to VGA converter ($17). So we are paying more for less.
Because you now have to buy the converters for the new video connector the price gets even higher. $29 for either the Mini DisplayPort to DVI Adapter or Mini DisplayPort to VGA Adapter, or $99 for the Mini DisplayPort to Dual-Link DVI Adapter.
Instead of hitting the customer with an al-la-carte of extra items to purchase, why doesn't apple continue to include a standard DVI port on the computer with the DVI to VGA adapter with the laptop?

I agree. If Apple would like more people to use the MB and MBP in a business environment you MUST have an easy way to connect the machine to a projector! Nickleing and dimeing people to get an adapter is CRAZY Apple! You are selling even the base machine for at least $1200! The cable cost you MAYBE $1.50 to make... Come on, put one in the box! Don't make people buy one to make it work with a projector! Almost every other laptop in the world comes ready to drive a projector DIRECTLY!

VGA to DVI adapter

I need to connect my powerbook G4 - the very first edition , which comes with a VGA conector on the back - to a apple studio display 17" LCD. Which adapter do I need?

You need a VGA to DVI converter

Having problems connecting a late 2011 Macbook Pro 2.2ghz i7 to a Sony KDL-32L5000 using a display miniport to DVI adapter (DVI to VGA cord). The TV is not detecting the macbook. Anyone have this problem?

You really have to mess with the resoluton, espescially the refresh rate, as it varies from projector to projector, monitor to monitor. Even within the same brand! Because so many manufacturers are trying so many different things to become the next cool kid on the block, and the way the formats are being configured that's now part of the game.
That's why so many professionally produced corporate shows hire a dedicated projectionist for the video presentations. Too many bugs in the honey.
Refresh & sesolution are the first things to look at.
Just so you know that colors in PowerPoint PC, and PowerPoint Mac, don't exactly match... go figure.
I forgot to mention another thing, sometimes it's the projector that needs to be tweaked.

Using 23" Cinema Display and VGA to DVI adapter??

I have 4 computers (2 deskop PCs, 1 IBM thinkpad laptop and 1 MAC). I have a DVI switcher. 3 of my PCs work great. My IBM thinkpad (T23) has an old style DVI connector on it that I cannot use (I thought I could until I got the Apple Monitor). I have tried a passive (no power) VGA to DVI adapter...but the monitor just ignores the signal. Do I need to purchase a $299 powered VGA to DVI adapter? I was thinking of looking for a PCMCIA (PC Card) video card with DVI out for my laptop, but havn't found anything when searching via google. Any information would be helpful. Thank you!
PowerMac G5 Mac OS X (10.4.5) 23" cinema display

The VGA to DVI adapter sounds like it's just an adapter that re-routes the pins to make the cables connect. The DVI connector can carry both analog and digital signals, so all the adapter would do is make a VGA cable with its analog signal go into a DVI cable that still carries the same analog signal. If that's the case, it won't work with the Apple display since the Apple display doesn't accept an analog VGA input even if you get the cables and adapters to hook it up. So yes, you would need the expensive VGA to DVI "converter" rather than just an "adapter".

Does a DVI to VGA adapter, and a DVI to DVI adapted do the same job?

A DVI to VGA adapter provides a conversion from DVI to VGA.
A DVI to DVI adapter, what is that? If the input is DVI and the output is DVI, what is the need for an adapter?

Can I use the Apple ADC to DVI adapter with a VGA monitor?

Hey everybody,
I have a quick question. I work on computers fr friends and family as a hobby. I have an ADC monitor and need ot be able to hook up computers with a VGA port on them to it. Can I use the Apple ADC to DVI adapter along with an Apple DVI to VGA adapter to successfully connect VGA computers to my ADC display? I was assuming this would work and ordered both adapters but now I have made myself nervous about weather or not this will actually work. Has anybody out there successfully done this? Thanks for your help in advance everybody.

You can't run an ADC display with a VGA computer without a converter. Adapters won't do it.
a VGA to ADC converter will drive the ADC display directly

If you have the Apple DVI to ADC adapter
<http://store.apple.com/1-800-MY-APPLE/WebObjects/AppleStore.woa/wa/RSLID?mco=18 72D402&nplm=M8661LL/B>
you could use it with a VGA to DVI converter
<http://www.gefen.com/kvm/product.jsp?prod_id=1310>
It might be cheaper to get DVI graphics boards for the computers and use the Apple DVI to ADC adapter.

Your title says "Can I use the Apple ADC to DVI adapter with a VGA monitor?". If you want to connect a VGA monitor to a computer's ADC port you need the ADC to VGA adapter
<http://www.gefen.com/kvm/product.jsp?prod_id=1299> You can't use an ADC to DVI adapter followed by a DVI to VGA adapter, because the ADC to DVI adapter doesn't pass the analog video signals needed for VGA.

Can I use the Apple VGA to DVI adapter to connect a PC to a DVI monitor?

Hi
Any idea of the Apple VGA to DVI adapter would work to connect a PC's VGA output to a DVI monitor?
Is it a simple pass through? Or are there drivers needed.

That adapter is for connecting a VGA display to a computer's DVI-I port. A DVI-I port has both digital and analog video pins. The adapter passes just the analog video to a VGA connector. It will not work in the reverse direction because a VGA computer does not provide digital video.
There are VGA to DVI converters that will connect a DVI display to a VGA computer.

Hp pavilion a6600f vga to dvi adapter problem

I have 2 LG flat screen monitors and a new HP Pavilion a6600f desktop. The VGA to DVI adapters that I've tried haven't worked. Do you know where I can get one that is the right one?
Solved!
Go to Solution.

the only thing I can think is the monitors dont support DVI-A (a for analog), and only supports DVI-D (Digital) Analog DVI uses different pins on a DVI cable.
If your monitor has a VGA input, use that its the same quality as DVI-A anyway.
