Dual monitor possible on G3 Beige 300?

I would like to be able to use a dual monitor set up, one for all my menus, and the other for workspace in each program. I am running OS 9.2 now but will be upgrading to OS X shortly after the holidays. Is this possible? What kind of hardware/software would I need. I already have 2 monitors, both 15 pin traditional PC monitors, one already being used by the G3. Any help would be great.

The Mac has been able to support multiple monitors arranged into an "Extended desktop" since the Mac-II days. Every well-behaved Mac Application can be used with it, and the monitors can be completely different and it still works great. The left half of a window can be shown on the left screen in 32-bit color, the right half can be on the right screen in Black-and-White. When you scroll it, they move together. There is no additional software needed.
Each display needs a Video card for its screen buffer. There is one built into the Beige G3 motherboard. Its 2 MB VRAM standard can be expanded to 6 MB VRAM. The built-in had a "two-row" connector -- you need a VGA adapter or Multiple Scan adapter to change to three-row "VGA" connector AND provide the right code so that the right resolutions can be supported.
Additional display adapters can be plugged into an available PCI slot. Mac-specific ATI cards with 16 MB VRAM or more and VGA connector are popular, and well-supported into Mac OS X. Allan Jones recommended a list on a post nearby:

Lenovo IdeaCentre K330B Dual Monitor Possible?

I was wondering if there was a way to have a dual monitor setup with the Lenovo IdeaCentre K330B. We have the Lenovo IdeaCentre K330B 7747 and this is for an office application so no gaming. The MTM is 77471CU. I cant seem to figure out what type of card is in there. Will I need to install a new graphics card? If so, what card would work?
Thanks for your help.
Solved!
Go to Solution.

Ok I got this figured out. There is a HDMI out and I couldn't see it because 1. it isdark under the desk and I couldn't move the computer well and 2. I am obviously blind as a bat and didn't see the HDMI out.
So yes this computer is dual monitor capable

Is it possible to connect my 2008 black macbook, to my new 2014 macbook pro retina display screen to make a dual monitor. If this is possible what cables would I need to buy?

You can try using Screen Sharing in the Sharing preferences. Or try a third-party utility such as ScreenRecycler.

Is a dual monitor setup with 2graphic cards possible?

HI.
What i want to do is run Archlinux on my Desktop but i dont want to miss my second monitor.
I could use both monitor on my nvidia graphiccard but i want to use the energy saving features too (wich dont work with 2monitor on one card) therefore my windows setup is big monitor on nvidia and the smaller one on the intel onboard card.
They both get recognized by lspci but only the onboard cards isy being used (the onboard card is the first card on windows too).
So is it possible to get it to work? Id really want to use ARchlinux on my Desktop too but i dont want to use it with one screen or without energy saving?
Working compositing is a must, i want to use gnome3 wich is the only reason to swich to linux for the Desktop (arch is running on the laptop for ages^^) but i dont need to, Win7 is working flawlessly fine and i didnt have to pay for it (msdnaa).
Thanks in advance!

hy do you need to clock down your card?
Most gpu have a function that clocks down the card@idle and or desktop.
In my case thats down from 850mhz(560ti)to 200mhz while using windows and 50mhz if the gpu load is low.
Thats about 20watts less then with full clock.
The problem is, that the gpu wont clock down with 2monitors on it, it stays at 850mhz.
Theres some driver tweaks for amd cards wich "fix" thatfix this (i believe its intentionl, 2monitors equals more load but its no problem with new cards...
Thats one reason i use my onboard gpu for the second monitor, it works well with windows and also means that swiching off fullscreen (games) to the desktop works a lot better, the second monitor can play a movie while playing wich doesnt work with one gpu and fullscreen.
I really dont need that with Linux since i use it for work and multimedia only but the energy saving feature is nice if the pc is on 8hours and more wich is often the case.
Can you tell which one do you run? I'm going to buy one for dual-monitor setup, and I'm looking for something that will work for shure.
As said dual monitor on one gpu works, amd can do 3monitors while nvidia can do 2 at once, that means if u intend to use 3monitors some day with ur card u have to buy an amd card.
i took the nvidia because is can use it to render videos with cuda support (its not working with all tools yet but its getting better and if it works its a lot faster then my cpu rendering).
PS: Thats one hread about the power saviing with 2monitors:http://forums.nvidia.com/index.php?showtopic=197557
since my monitors dont share the same resolution it seems that theres no way to make it work .

Dual Monitors w/ G5 - two users possible?

A question for those more knowledgeable than I about dual-monitor operation: Assuming I have a 2.0gHz G5 and two 23" DVI displays, can I run separate user accounts simultaneously on the same machine?
In other words, can the person across the desk from me use a separate monitor and keyboard connected to the same G5 and log in under another account while I'm working away under my account?
Thanks for any help you can offer.

Hi
it's an interesting idea but I don't think it's possible. You can set up two user accounts and use fast user switching to switch between them, but I don't see how both accounts can be used simultaneously. For a start there's no way for the computer and OS to know which keyboard, mouse and monitor are being used by each user.

Hp pavilion 23 dual monitors is it possible

now my computer is an all in one and doesn't have a vga or hdmi plug in it how do I set up dual monitors then

Hi,
You will need to use an USB to video (VGA, DVI, HDMI) adapter. If you are using W8 then check with the manufacturer for compatibility.

Quicksilver dual A1038 monitors possible?

Hi,
I inherited a Quicksilver 2002 and have a single A1038 monitor. My question is, can I run a second A1038 on it somehow? Would I need to add an additional graphics card with ADC connector (if so, what would be compatible?) or could I use some sort of ADC splitter if there's such a thing?
Thanks

Hi-
Welcome to Discussions!
Almost all G4 graphics cards support dual monitors.
However, to run another ADC monitor, your graphics card would need a DVI port, and then you would need a DVI to ADC adapter:

You can't install two AGP graphics cards, which are the only ones with the ADC connector.

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.
LINKS
EVGA Plus:
http://www.evga.com/articles/409.asp
Their literature does not mention Mac OS X compatibility. However, the underlying technology is made by Display Link. You can download beta Mac OS X drivers from their site:
Go to Display Link to download the beta Mac OS support -- see
http://www.displaylink.com/macbetadrivers.html
The disk image includes a very well written PDF document that explains the driver's status and limitations.

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!

How to enable a dual monitor mode

I have a MSI FX52000 VTD-128 board which suppose to support a dual monitor mode. It has D-Sub analog, DVI and VIVO connectors.
Would it be possible to connest primary monitor to DVI and secondary to analog output or only Video Out can be used for the secondary monitor?

Have you installed the latest "Forceware" Drivers?...I think MSI's 52.70's are great...How you should go about setting up for two displays is to go into NVIDIA Driver Control Panel>trouble shooting>Click on the "Detect Displays" Button after you connect the other monitor ...Sean REILLY875

How do I set-up my TV as a dual monitor for my MacBook Pro?

Hi
I have a mid-2009 MacBook Pro running (OS X 10.8.2) Mountain Lion, and recently I rearranged my home workspace so that I can view my TV from my desk while I work.
I would like to set-up my TV as a dual monitor for my MacBook Pro, so I can stream videos on my TV screen and have the whole screen to do work on my MacBook Pro at the same time.
Is this possible? I've seen people use TVs as a mirror display (where it works as their main and only monitor), but never as a fully operational dual display.
As an example, I would like to have my MacBook screen showing a desktop with the whole screen devoted to Photoshop, while I have another desktop running on my TV, which shows an internet browser or other application.
If this is possible, what cords/hardware would I need, and what are the settings that will enable me to do this?
- My TV is a modern flatscreen LCD, and it has two HDMI ports in the back.
- It's about 9-10 feet from my desk.
If anyone could help, that'd be awesome!
Thanks.

Yes, you can do that.
You'll need a mini displayport to HDMI adaptor:
http://store.apple.com/us/product/H1824ZM/A/moshi-mini-dp-to-hdmi-adapter-with-a udio-support
and an HDMI cable long enough to reach your TV
(look on Amazon or Monoprice for the best price on any of those parts)
In your display options, you will just choose extended desktop vs mirrored display.

Dual monitor setup - need laptop on the left

Hi All
I'm running a dual monitor setup - specifically a HP G72 laptop and a widescreen monitor. I use the monitor as the default and sometimes I want to use the Laptop as a secondary screen for watching TV etc. My desktop is Enlightenment, I just changed to it from Gnome. My issue is that I want the laptop to be on the left of the monitor - that's how it is physically positioned - but when I switch the Laptop screen on all my applications shift over to the laptop screen. I've written 2 scripts, attached to hotkeys, one to turn the laptop off and the other to turn the laptop on. The script to turn the laptop on is as follows:
xrandr --output LVDS1 --mode 1600x900 --pos 1600x0 --rotate normal
--output VGA1 --primary --mode 1920x1080 --pos 0x0 --rotate normal --left-of LVDS1
This works fine, applications stay where they should be, except that the physical position is incorrect; VGA1 should be to the right of LVDS1 like this:
xrandr --output LVDS1 --mode 1600x900 --pos 1600x0 --rotate normal
--output VGA1 --primary --mode 1920x1080 --pos 0x0 --rotate normal --right-of LVDS1
However, when I use the second script all of the applications shift to the laptop but at least the physical position is correct. The issue appears to be something to do with laptops, almost as though when it's a laptop the default monitor is forced to be on the left. Has anybody got any suggestions how to get around this issue?
Thanks
Richard

This is due to your window manager treating the two monitors as a larger 'desktop' area - that combined with your specification of the pos=0x0 you are telling it to do this.
If you have only the VGA output on, the top left corner of the VGA monitor is 0x0. If you open a window, and it is placed 10 pixels in and down from the top left, it is at coordinates 10x10 in the x session. Then you turn on the laptop monitor and specify that the top left corner of the laptop monitor should now bo considered 0x0 - but nothing is done to move the windows, so the window with coordinates 10x10 is now near the top left of the laptop monitor.
I see 3 possible ways of acheiving what you want:
1) swap the "pos" parameters in your xrandr commands so that the monitor on the left is always at 0x0 and the one on the right is always at 1920x0 (or whatever). This will leave a large area of available X desktop that is not visible - I don't know how your window manager will treat this. It might try to map windows on the laptop screen space even though that screen is not on. I know openbox is easy to configure where it tries to place windows.
2) Keep the VGA monitor always at 0x0, but place the laptop monitor at a negative offset when you want it on. I don't actually know if X allows negative coordinates like that, but it's worth a shot.
3) Configure your window manager, or use a different window manager, so that it is aware of the two screens and treats them reasonably (e.g. moves windows when the desktop area is changed).

Dual Monitor Setup/Home Network/Sync--11" MBA & 21.5" iMac via Thuderbolt cable?

11" MBA & 21.5" iMac both purchased in August 2011 running Lion
Is it possible to setup my MBA & iMac where they will sync? I have them connected via thinderbolt and want to be able to connect when I get home and sync all my folders [notes, cases, papers, etc...]?
If this is not possible is there a way to transfer files between my two machines using the Thunderbolt cable? I ask because even though my MBA has a Thunderbolt port, there is not "Fire Wire" option under "System Preferences →Network" like there is on my iMac?
In a perfect world I want to be able to hook up my MBA & iMac via Thunderbolt cable, have them both controlled by my Magic Mouse & Keyboard I use with my iMac as dual monitors and be able to transfer files back and forth freely. I understand this may be a lot to ask but thought I should throw it out there just in case there was a way and I was not doing something right.
I appreciate all the help by everyone in the Apple Commun ity

OK great info!
I found 2 possible ethernet to USB adapters:
By "Plugable": USB 2.0 to ethernet LAN wired network adapter - seems this will work, but I'll contact Plugable.
2. Apple USB Ethernet Adapter
Easily connect your MacBook Air computer to an Ethernet network with the Apple USB Ethernet Adapter. Small and light, it connects to the USB 2.0 port of your MacBook Air and provides an RJ-45 connector that supports 10/100BASE-T performance. BUT NOT SURE IF THIS WILL WORK ON ANYTHING BUT a MacBook Air…
One person commented:
This little gem used to be the device of choice for adding a second Ethernet interface to a Mac Mini Server and I'd been using one that way for about a year. After doing a software update to 10.6.6 it stopped working. Forewarned is forearmed – it appears that Apple is finally enforcing the MacBook Air system requirement.
Thanks for any additional comments.

Hello,
I had the same problem with a nVidia GT120 card (2009 Mac Pro standard). OSX wouldn't show the gray screen on the 3090, even when it was connected alone (to the DVI port). Also, the login screen would always revert to the secondary display (connected thru the mini display port to DVI adapter).
After login, all was well.
Now I've solved the problem with an nVidia GTX 285 card. The 3090 is connected to the n.1 DVI port and the secondary display (a 1600x1200 Eizo L997) to the n.2 DVI port, and the Mac Pro boots correctly on the 3090 (gray screen and everything, at full 2560x1600 resolution).
Note that the first time I booted up the Mac after replacing the GT120 with the GTX 285 I had the same problem, and solved it by disconnecting the secondary display and then rebooting with the 3090 alone. Now everything works as it should.
Dont't know if there is a bug somewhere (EFI, maybe) of if the GT120 and your ATI are simply unable to work at full resolution before OSX desktop loading.

Dual monitor setup with seperate resolutions

hey guys!
i currentley run thye latest version of archlinux with the cinnamon desktop environment and an nvidia geforce 7300SE graphics card.
im running a dual monitor setup with one 27" 1920x1080 monitor and one 27" 1024X768 monitor
because they have the same physical size they line up perfectley but because the resolution is different programs/mouse cursor movement doesnt, is there any way (without changing the resolutions) to compensate this effect so that in the eyes of linux/cinnamon the monitors line up so that for example dragging a window goes seamlessley between the 2 monitors.
i HAVE found out the panning option in the nvidia x server settings, but that really isnt what i am looking for...

A magnifier following the window down to the pixel, zooming to the exact size of 540 pixels the 384 pixels window could create an illusion of just that. It would be highly impractical however, not mention all the hacking time. Even if you would manage to get two screen with different sized icons, so that they match visually, the windows and fonts resizing on the fly, wmctrl might help with windows alone, no their themes (buttons, borders thickness etc.), you would still be left with a visually differently sized mouse cursor. Technically such a feat should be possible, but who is going to code it? Nvidia?
