Dual monitor/ADC

Ok, I just obtained a 20" Apple Cinema Display with DVI. I also have another monitor with DVI. Can anyone recommend an inexpensive DVI to ADC adaptor (or VGA to ADC) or any other alternatives I might have? I am on a 1.8 Dual G5 with GeForce FX 5200.

will the display preferences show more resolutions?
It will show the optimal resolution, and possibly a few other options. Digital displays are not like analog, which have a multitude of possible resolutions.
For the 20" Cinema Display, expect:
1680 x 1050 (optimum resolution)
1280 x 800
1024 x 640

Dual monitor setup without using the ADC?

Would it be possible to run a dual monitor setup using a DVI splitter cable from my (2009)Mac Pro?
I've seen some old forums referring to the 2006 models saying that this wouldn't work and instead you'd get the same image on both screens but the newer Mac Pros state they have "Dual-Link DVI ports".
Just wondering whether this means what I think it means and you can connect two monitors via a dual link cable and get essentially, two monitors running independently as opposed to the same thing on both??
Hope it's staightforward and me just being slow.

The GT120 features one Dual Link DVI-I port and one Mini DisplayPort .
The DVI-I is Dual Link capable, and also can be directly adapted to VGA.
Single-Link DVI is a serial interface that carries three data bits in each signaling interval, as well as control signals. In general, Single-Link supports displays up to 1920 wide. Dual Link DVI is the same except that it carries six data bits in each signaling interval, supporting displays over 1920 wide.
DVI screen drawing is very similar to VGA screen drawing, and the data sent are digital "scan lines" left-to-right row data, top-to-bottom with entire screen data sent about every 60 Hertz. Analog VGA signals are sent at the same time on a separate set of pins.
DisplayPort and its Mini variant are inherently a packet interface, but can be coerced to produce a "Dual Mode" signal that approximates Single-Link DVI. Getting Dual-Link DVI or VGA from DisplayPort interface requires a non-trivial converter than contains chips and requires power.
Executive Summary:
If you have one display that is wider than 1920 or VGA, attach to the DVI-I connector with an appropriate cable.
Running a Mini DisplayPort display from the Mini DisplayPort requires only a cable.
Single-Link DVI can be had from the Mini DisplayPort with a cheap adapter.
Dual-Link DVI or VGA requires an expensive Active Powered converter which can cost US$100.

The graphics card has two connectors on the panel one is the standard VGA and I thought that the other was a DVI interface, but it looks like It has 10 rows of 3 pins plus the ground bar for the DVI. I can't find a cable or adapter to fit this connector.

Hi
I suspect it's an ADC connector. If it's the stock graphics card that shipped with the 800MHz Quicksilver that's almost certainly the case. You can buy an ADC to DVI connector cable for around $30 (although don't confuse it with the more expensive DVI to ADC adapter). ADC combines a DVI video signal, power to drive a monitor and a USB signal for a hub in the monitor into one cable/connector. It's specific to Apple, although even Apple now use the more industry standard DVI.

Help needed to connect dual monitors.

Hi everyone. Here's my problem, I bought two Samsung SyncMaster 913v LCD TFT Displays.
Both of these displays (since they aren't the digital LCD) connect the same way my old Sony Trinitron MultiscanG400 display connected, which I believe is the VGA connection or SVGA or whatever... I'm not smart enough to look into the difference.
Anyway, I have the right Graphics/Video card to run dual monitors. I'm using the GeForce 2 TwinView and it has the required 64mb VRam.
My problem is that there is only one port on the back for monitors. I believe the connection type next to it is an old pre-usb printer/scanner type of connector, LPT1 or whatever those are called.
So do I need an adapter/connector to hook up both of my monitors to use it as a dual display? If not, what do I need to do?
Thanks.

Hi,
To clarify the last post by PB PM. Your present card meets those requirements.
The GF2 Twinview card is sufficient. It has two outlets, one is VGA the other is ADC (Apple Display Connector). You will need a ADC to VGA Adapter, they cost @ $25-30. Hook one monitor to the existing VGA outlet, the other to the adapter on the ADC outlet.
One example is here: http://eshop.macsales.com/item/AddLogix/MCAADCVGA/
You can google for other prices.
After the monitors are connected you may need to go to Displays Pref's and set it for dual monitors in Mirror or Span modes.

Dave

Dual Monitor Out of Frequency

I am reposting this from another area to see if get a response here.
I have a G5 Dual 1.8 machine with a GeForce FX 5200 DVI-VGA and ADC-VGA adapters. It drives to 17in Daewoo LCD monitors.
It all worked fine with dual monitors until I upgraded to 10.4.3. First alternatively one of my monitors went out of frequency after working through most of start up. Then the next causing the same work. Then after getting it to work by swapping around the monitors and reseting the frequency down to 75hz, both monitors went out of frequency.
I reinstalled tiger and upgraded all the way to 10.4.2 and am able to use both monitors. I did this in both archive and full mode. I also upgraded in steps several times so I am confident it is a problem that ocurs with 10.4.3 upgrade.
So it looks like their is a bug in 10.4.3 that does periodically puts the frequency out of range for the monitor.
I am posting this to be helpful to others who might experience this problem and to request any suggestions that I might have missed.

Now I just tried 10.4.5. Still the same problem. So again I went back to 10.4.2 and the problem goes away.
Given the lack of responses to my posting, I am puzzled - there must be someone else out there with a fx 5200 nvidia and vga monitors - why am I the only one with this challenge?

Dual monitoring question...

Hi,
I would appreciate any help i can get in regards to setting up a dual monitoring system on my power mac g4. I have the mirror door version which i believe has a ATI Radeon 9000 Pro graphics card (i may be wrong as i don't know much about this side of my computer) and it has two connections, DVI and VGA... I am currently using the DVI connection to run an original 17" apple cinema display off of DVI.
I am wanting to connect another one of these monitors and am wondering the cheapest way of doing this. Can i get a VGA to DVI convertor similar to DVI to VGA? or is there a PCI option?
Thanks.

First, check exactly what graphics card you have by running the system profiler. If you're not familiar with this, click on the Apple menu item at top left and select "About this Mac" Then click on "More info" to run the system profiler. Once that is up select "Graphics/Displays" to check which card you have. Anyone advising needs to know exactly which card you've got, guesswork might lead to suggestions that don't work.
You can simply plug another display into some cards that have multiple outputs, but some will only drive one display at a time. If you have in fact got a Radeon 9000 then you're in luck. You have an ADC connector and a DVI, and you can run a second display from the ADC connector by using an ADC to DVI-converter and a monitor with a DVI input. You could also use any old Apple monitors that take ADC connections with a suitable cable, but modern displays would be a lot better.
There used to be plenty of Mac PCI cards around and any of those would work in your G4, but the problem nowadays would be finding one. I got one on eBay for my G4 and it works a treat driving a second display, but that card is no longer easy to find and wasn't the best choice anyway. Your Radeon 9000 (if that's what you have) is a much better card.

Want to run dual monitors;

I want to run dual monitors; my video card if GeForce4 MX, bus is AGP; vram 32 mb; vendor nVIDIA; it is in my PCI slot #1 (I have a scuzzi card in slot 5 and nothing else).
At present I have a Dell CRT 32mb as my main display, with mirror turned off.
Now I have hooked up a Belkin ADC to DVI adaptor to the ADC output and connected it to a Sharp monitor with a DVI input.
In my system profiler it says "NVDA,Display-B", cjlick on that is says no display connected.
So—it won't run.
What is wrong with this picture?

Does the new monitor work if you click "Detect Displays" in system preferences?
If it still doesn't, try connecting the Sharp monitor directly to the card's DVI output (instead of the Dell) and see if it works then.

If you could find a real ADC to DVI-I adapter, it would work, but the Dr. Botts ADC to DVI adapter
<http://eshop.macsales.com/item/Dr%2E%20Bott/ADCDVII/>
will not work with a DVI to VGA adapter. It does have a dual-link DVI-I connector, but the pins for analog video (and dual link) do not connect to anything. They use this connector because some non-Apple digital displays come with DVI-I and/or dual-link DVI plugs, when they only need DVI-D signals. The Dr; Botts adapter and (all others that I have seen) are only ADC to DVI-D. Even if they connect the dual-link pins from the ADC to the DVI connector, the result will be single-link DVI-D, since no ADC cards provide dual-link signals. There is no reason (other than cost) why an adapter couldn't connect the analog video signals from ADC to a DVI-I connector, but I don't know of any that do.
From their web-page:
"DVI Extractor II makes an ADC-compatible display out of virtually any third-party flat panel display"
Note they say "flat panel".
You need an ADC to VGA adapter. They are listed from $40 to $150. Still less than a compatible replacement graphics card, although you can get a card faster than you current one, if you pay enough.

Please help with these dual monitor problem

Ok,
Well i am a final cut pro editor and i have a power mac g5 with 1.6 ghz.Its an older one but it runs great for what i need done. Anyway i wanted to go dual monitors so i went out bought a monitor and set it in place. However my graphics card only had 1 DVI PORT (Which had my main monitor on) and the other one was a ADC port. I bought a ADC to DVI-D and then realized it was the wrong one. Those Adaptors are very hard to fine, so i made up my mind a decided to forget that and get another graphics card. However i am not very good with that stuff and i really dont know which one to buy. Some others gave me a list but they were not the same as mine (slots didnt match)
*Here is my card that i have now*
http://www.layton-family.net/stuff/stuff_files/image008.jpg
Can someone point me in the right direction about going to best buy and picking up a new one that will hold dual monitors and still run motion at a good level.

Aperture, dual monitor, x800 card help

I am adding a 30" monitor to my current 20" monitor for a dual monitor setup. The x800 card has an ADC and a DVI port. I'm assuming only the DVI port is dual channel so I guess the 30" has to go there. My 20 inch is also a DVI hookup, do I just get an ADC to DVI converter?
Also do I slow things down at all now that the card has to control two big monitors? Can the x800 control these two monitors adequately, Aperture taxes the GPU a lot - will this slow down at all?
Also what happens with calibration? I have the GMB Eye-one. Do I calibrate each monitor separately or (if I recall) only calibrate the 30" and let the 20" stay uncalibrated for palettes and such.
-Thanks

similar setup here ...
the 30" is on the DVI port and the 23" is on the ADC using a belkin ADC to DVI connector ...
i calibrate using a spyder pro ... when i calibrate, i calibrate one monitor and save the profile with the size in the name - short term memory is very short ... the under displays->arrange i drag the menu bar to the other screen and it makes that the primary and i calibrate it - again with the size thingy ... i then switch the arrangement back and presto chango i have to rearrange most of my desktop icons - haha ... otherwise everythign is fantastic ... just make sure you turn on the monitors and let them warm up for an hour min - 2 is better for the 30" ...
so you leave one uncalibrated if youd like, as you create a profile for each ...
i have seen no slowdown since adding the 30" a few weeks ago ... and i work with 5D (~75%) and 20D RAW files ...

Cheapest video card for dual monitors on a G4 Sawtooth

Hi guys,
What would be my cheapest alternative to get a dual monitor (extended desktop) environnement with my G4 Sawtooth. This is an AGP G4.
Can I get a cheap video card with one outlet and then plus each monitor in one card (ie: 1 in the new card and 1 in the old one) ?
Or do I need to buy a card that supports 2 monitors?
I would like to spend as little as possible. I currently have the ATI 16 mb card that came with the system and I run both OS 9.2.2 and OS 10.3.9
Thans for your advice,
xenakis

Yesterday I installed a nVidia GeForce4 MX AGP out of a 2002 Quicksilver tower into my own AGP Sawtooth.
It has VGA and ADC connections and can apparently support two monitors at the same time.
My second vidio card is a MPDD card, but I may pull that now that I have a dual-monitor card. Sonnet sells something similar. They have blue & yellow connectors. These things are not high performance but they are OK to use with just about every monitor on the planet and any MacOS from 7.1 to 10.5 and beyond.
Cheap on eBay. Probably you could be even cheaper and pick up a 16-meg PCI card out of a B&W G3 tower.

Need videocard that supports dual monitors and Rotation -for PowerMac G5

I'm looking for a videocard that supports dual monitors and Rotation for PowerMac G5. I've got two Dell 2407WFP monitors rotated to 90 -I've been running an ATI Radeon X1900 256 pcie16 but apparently it is over heating -not even exactly sure if that indeed is the case but all the symptoms I've looked up online point to this problem. Anyways -just looking for a card that will do the job -I don't run games -this is just for work machine doing photoshop and related programs. Thanks for any help anyone may have!

Hi-
A flashed card is a WinPC card that has been modified to accept a Mac ROM to provide for Mac compatibility.
Occasionally, soldering and other physical modifications are required.
Without this modification, a WinPC graphics card cannot be used in a MAc.
Without this modification, Mac users are limited to only a handful of used, OEM options.
The Geforce 7800 GS is the only 7800 card that may be used in a G5 (or G4).
The card must have been or be converted to Mac compatibility.
For dual monitors (DVI) the best performance choices are the Geforce 6800 Ultra (flashed or OEM), a rare, but occasionally available Geforce 6800 GT (flashed), an OEM Radeon X800XT (use ADC/DVI adapter on ADC port) a rare and expensive Radeon FireGL X800 (flashed).
These are the only performance oriented cards to offer dual digital display support.
For less demanding graphics work, an OEM Radeon 9650 offers dual digital output.
Other OEM graphics cards will have either DVI/DVI or ADC/DVI.
All OEM graphics cards are only available as used.
All cards are easiest to obtain on eBay.
Prices vary, but deals can be found.
Expect to pay $150-$325 for any of the cards listed.
Any card considered MUST be stated as Mac compatible, unless you are willing to research and learn how to perform the necessary modifications.

Can DV6-1352 Handle Long-Term Dual Monitors on the Graphics card

Hey guys,
Very simple question here. I wanted to set up a dual monitor thing on my Dv6-1352. I believe it has this integrated graphics chip : Intel® Graphics Media Accelerator 4500MHD. I wanted to use the dual monitor capabilities on it, but I was wondering if over time, extended use of the graphics card due to dual monitors would make it over heat/kill it. I don't plan on playing games, just using it cuz A) Its pretty cool B)It'd help increase efficiency in my engineering school work which requires I have a lot of things open at the same time.
Thanks in advance!

Hi
The retail version of the 9600 comes with two DVI ports.
I think some companies were selling OEM versions with an ADC and DVI port that had been pulled from G5s and modified to work in G4s.
In a G5 both ports work fine but in a G4 I don't think the ADC port is powered. The Quicksilver does actually have the required internal power slot, but I think it's in a different position on the logic board. Consequently the power stub on the card which lines up with the slot in a G5 doesn't line up with the slot in a G4.
I think you can still use two monitors by using an ADC to DVI adapter cable. This would convert the unpowered ADC port into a second DVI port.
To connect two DVI monitors, you'd just need one ADC to DVI adapter cable.
To connect two ADC monitors, you'd need the above adapter plus two DVI to ADC adapters which are fairly expensive ($99 each).
To connect one DVI monitor and one ADC monitor, you'd need one ADC to DVI adapter cable and one DVI to ADC adapter.
The retail 9600 doesn't have an ADC port either, so either way you'd end up buying some form of adapter in order to use an ADC monitor.
I hope this helps.

How to set up dual monitors with a Mac Mini

The Mac Mini has only one video output port. I very nearly didn't buy a Mac Mini system because I need to work with two monitors. I use the second monitor to display information in Web pages, PDFs, and Word documents while I am working in the main window.
However, I discovered after quite a bit of Googling that it is possible to set up dual monitors using an inexpensive USB video adapter (about $70).
So I bought my Mini (1.83Ghz, 2GB RAM, 200GB 7200rpm Seagate Momentus), and I also bought a USB video adapter called the EVGA Plus.
I've installed this system and used it now for a week, and I am quite pleased with it. So I thought I'd pass this information along to anyone who's interested. Please note that, although this is my first post to this forum, this isn't spam -- I have no financial relationship with any of the companies mentioned here, other than as a customer.

NOTES
* The DisplayLink driver is beta. It doesn't support 2D or 3D accelerated graphics. You can't use it to display iPhoto slide shows, for example. However, I need to be able to display a Web page, document, or PDF in the second monitor while I am working in the first. I've found this solution to be quite acceptable for this purpose.
* Several other companies make USB video units that use the same DisplayLink support, so they should work, too. However, they are more expensive -- largely because they're set up to function as port expanders, I believe. The EVGA Plus was the only unit priced under $100 when I did my search.
* USB does not have very much bandwidth, so you might be surprised that to hear that it's possible to use USB to drive a monitor! You'll find that the display isn't as fast as DVI, but for my purposes, I've found it quite acceptable.
* The EVGA Plus comes with a terrible USB to mini USB cable that will cause all sorts of display problems. Replace it with the type of cable that is used to hook up digital cameras to a USB port.
* Once everything is installed, you can use the Displays in System Preferences (or just click the icon on the menu bar) to adjust the second monitor. You can choose display resolutions (depending on your monitor's ability, of course). Rotation works. You can also right-click the second monitor and choose a different background color or graphic.
Don't expect miracles. Don't go this route if you want to run videos or games in the second monitor. And if you get an EVGA Plus, replace that horrible cable!
I hope this information is helpful.
Bryan

There has been quite a lot of discussion here about driving twin displays with the mini, and more recently about the potential for USB video adapters to facilitate this, particularly in the light of several vendors claiming they have suitable MacOS devices and drivers 'almost ready'.
The DisplayLink solution seems to be the one most suggested as viable, though it's a pity they have not yet been able to move their drivers from beta - I suspect that puts a few people off. It's therefore good to hear of a real-world experience that should help others decide whether or not to go this route!

Lenovo 3000 N200 0769-ALU Dual Monitor Support
