Video DVI splitter

Hi, I was wondering if Mac has a video DVI splitter. I have DVI to Video Adapter for My Mac Mini, in a perfect world I would like to switch from my monitor to my TV with out having to disconnect any wires.

We have such a device in our display lab at work, but it has multiple output ports, not two, and it cost a bundle. DVI distribution boxes are AFAIK test equipment for labs and I have not seen the equivalent as a simple, two-port consumer device. Still, you might want to look around. I could be wrong and you may find one.

DVI Splitter - video adapter

Hi,
Can i run both a DVI-VGA & DVI-Video adapter through a DVI splitter from my MBP?
Thanks

That might work under Windows but the driver in OS X does not support it.

DVI splitter cable on 2 monitor setup

I set up my G5 with 2 monitors utilizing both ports on the graphics card. I want to add a Wacom Cintiq tablet which has a video display and am wondering if I can split the second port with a DVI splitter cable so I can have display on monitor 2 and the Cintiq.
1. Will it work?
2. Will it draw too much from the display adapter, thus causing it to fry?
3. Has anyone done this set up themselves?
TIA for the info!

Hi-
Two monitors are working the 9600 pretty hard.
Realizing that you probably want to get by on the cheap, I can't recommend a simple DVI splitter.
I don't think you will get satisfactory results.
Another issue is, with any type of device that uses a single port for multiple displays, is that the two connected monitors need to support the same resolution.
A DVI amplifier would provide the additional power and signal boost needed to run additional monitors.

Dvi splitter cable will extend the screen?

Hi everyone, I have a MBP 8Gb RAM. I would like to go dual monitor and extend my desktop.
My Mac has a single video out port, specifically a Mini DisplayPort.
Using a dvi splitter cable will just give me the ability to extend it? Actually I'm on a single monitor and I'm keeping my mac shut on a BookArc stand.
If not, what should I use?
Thank you in advance.

If a DVI splitter works at all, it will only give you two external monitors that display exactly the same image, rather than an extended desktop.
The cheapest way to add a second monitor to your machine for extended-desktop use will be a USB video adapter like this:
http://eshop.macsales.com/item/NewerTech/VIDU2DVIA/
Note that it is limited to a maximum of 2048 x 1152 resolution, and it won't be responsive enough (because of the slow USB connection) to use for action gaming, animation, etc. Use your other monitor for work that requires a highly responsive screen.

Mini + DVI splitter = colored static (argh)

What I want to do is mirror one of the video outputs of my Mini (one LCD on my desk, one on the conference table). I am already using both video outputs of the Mini (mini DVI and mini DP) to drive dual monitors (extended desktop mode) on my desk, so I have no spare video outputs.
Previously, I was using a DVI splitter (takes one DVI in, sends two identical DVI signals out), but with the new mini I get one good DVI signal and one that's all colored static/snow. I have checked the functionality of the powered DVI splitter using an old Macbook, so that is working fine (can mirror to two displays). So the culprit is the new Mini.
I suspect that the problem is the new HDCP encryption used in the Mini's video output. It would stand to reason that the Mini can only exchange encryption keys with one of the displays, so the other one will not be able to decrypt the video stream and thus display garbage (colored static/snow). This is annoying since this setup worked previously before Apple started using HDCP.
Any ideas?
I have yet to take this to the Genius Bar ...

Matt,
It's been quite a while since I had this problem, so I was looking for my notes on fixing it. No luck there.
The bottom line is that the "native" refresh rate on your KVM is far enough out of specs for your monitor that it's affecting the display. When you plug directly into the mini, the display automatically senses the correct refresh rate and looks fine.
It's a hack, but here's what I did (after giving up on manually modifying the settings in Terminal and failing miserably):
1. Plugged the display directly into the mini and created a "calibrated" color profile for it in both user and admin accounts.
2. Connected the KVM and booted in safe mode, selected the "calibrated" color profile with appropriate resolution in all profiles.
2b. Made sure I unchecked the +Show profiles for this display only+ box in the Display > Colors tab for all users.
3. Plugged in the KVM and restarted in safe mode, doing 1 & 2 above.
4. Restarted and manually set the color profile and resolution.
It can take a few tries to get the settings to "stick."

I have a MB Pro that is running Lion; I also have two external DVI monitors and a DVI splitter in hopes that I could run the two monitors with my MB Pro. This actually works fine, but I am unable to "extend" the desktop. Any insights?

You cannot have a extended desktop using a splitter. All that does is mirror the pair attached to the splitter.
You can do this however using a Matrox DualHead2Go.
Other solution would be to attach one monitor to your video out as you do the splitter and attach the other via USB (assuming the adapter supports the monitor's resolution).

DVI Splitter working in reverse?

This is sort of a general question.... But I was wondering if a DVI splitter will work in reverse. Basically what I want to do is use my monitor for my Macbook Pro, and for my PS3, but I want to optimize the picture on both. The best way I can think of doing this (without having to unplug whichever one I am not using at the time) is to plug a DVI splitter into my monitor (coming out of the monitor) and than plugging my Mac into one side, and my PS3 (via HDMI-DVI adapter) into the other side. If I do this, will my monitor recognize whichever one is powered on? Or will I just confuse the crap out of the monitor?

I don't think what you propose will work. This is what KVM switches are made for.
http://en.wikipedia.org/wiki/KVM_switch
But if you want to save what a KVM switch would cost, the free, simple, no-sweat solution is just to plug the monitor into one computer at a time.

Possible to use 30" on PC using DVI splitter?

Someone I know believes that you can use the 30" Cinema on a PC with a non-dual link graphics card simply by plugging the monitor's cable into a DVI splitter and then plugging it into both DVI ports on the card. Is he right, or am I correct in telling him that won't work?

It won't work. Dual-link DVI is not the same as dual DVI.

Need DVI splitter.

Want to have 2 monitors on my mini. Where can I find a DVI splitter?

Would the above link just mirror the desktop on both displays or provide your more desktop space to utilize?
If you're looking for a splitter that may be sufficient, if youre looking to expand the amount of desktop space to use across 2 screens, the matrox expansion modules should work.

DVI Splitter on 2006 Mini

I have a splitter on my 2006 mini. It's a DVI to DVI/VGA. Can't get the TV(VGA) to get a signal if the monitor(DVI) is connected. Unhook the DVI monitor and the TV picks it up. I want to have both the TV and monitor hooked up at the same time. I'd also like to get my TV(which doesn't have a DVI connection) beyond a 800x600 resolution. Is there a way to do that with the VGA or am I stuck with that? Also, can I get it to fill more of the screen or am I stuck with the small screen it fills?

These splitters do not let you use both connections at the same time.
If I remember correctly that model of Mac mini has just a single DVI connection on the back and would have come with a DVI to VGA adaptor in the box. Obviously there is no way to fit a second video card, but it is possible to use a USB to VGA adaptor which would let you connect both displays at the same time. See http://www.displaylink.com/shop/adapters/
If your monitor also has a VGA port then you could get a VGA switchbox (not a KVM) to switch the output between the monitor and the TV. See http://www.monoprice.com/products/product.asp?c_id=101&cp_id=10106&cs_id=1010601 &p_id=54&seq=1&format=2
A newer Mac mini would have two built-in video interfaces, the current model has a HDMI (which can connect via the included adaptor to a DVI monitor) and a Thunderbolt interface which can connecto to a VGA display using a additional Mini Displayport to VGA adaptor.

DVI Splitter ?

I want to add a second cheap LCD for toolbars and other stuff to extend my desktop. I already have a DVI-PAL Video connected to my TV. A DVI switch is very expensive so I thought maybe I could just split the signal using this.

(I don't know if the QUAD uses DVI-I or not.)
Would this work?
Thanks in advance.

The Quad does use DVI-I signals, but that adapter will only give you the ability to mirror the displays - you'll have the same thing displayed on both monitors.
You might want to consider adding a second video card for this purpose. You can order the nVidia 6600 from the Apple Store and use it to drive either a second monitor, or let it drive the TV converter and use the primary video card's two DVI ports for your monitors.

Thunderbolt and DVI splitter

I have two DVI/VGA monitors I use for work and looking to see if there is a splitter from a thunderbolt port that would let me use these with my Macbook Air. My Air does support thunderbolt displays just been trying to google such an item and not sure if its possible.
Thanks in advance.

There is this:

Audio/Video Output Splitter/Selector Help

Hey guys, quick question:
I use my late 2009 mac mini to run my DVI monitor most of the time but sometimes when I'm watching downloaded stuff I switch it over to my LCD TV which means I have to switch the display cable in the back and the stereo audio out cable from my computer speakers to my TV. Is there such a device where I can just switch between the two without having to juggle the cables every time? I know they make DVI splitters but what about DVI and audio?
Thanks in advance!!

Take a look at the Belkin website. I have one of their KVMs for switching between VGA, USB and audio between my PC and Mac. They may have something for DVI too.

Video DVI extension cord

I want to have my computer further away from my monitor than the cord allows. I can't find a DVI to DVI extension cord that will work.... need it to have a male to female configuration. Also, I can't find a coupler to use with a DVI to DVI male to male cord (which is the only kind of cord I can locate). Any suggestions?

Do you mean something like this? :

You'll want to check your card to be sure which one is right.
Can't vouch for 'em, but they've got plenty of options!

Solved: Noise in audio line-out when connected to an external video (DVI)

Ok. I kept looking for possible solutions to this problem. I finally found the solution! If you lift the ground out of the audio cable, completely disconnect the ground conductor, unsolder it, cut it.. the noise goes away. Here's why I had the problem in the first place. Common practice wiring when going from unbalanced to balanced, or from a two conductor+ gnd (stereo) to two mono+ gnd, calls for a specific wiring with the ground/shield conductor. (BTW, most commercial audio cables like those sold in the Apple store will exhibit this problem: e.g. any 1/8" stereo to L/R mono RCA or 1/4" connectors) If you disconnect it, running just the signal conductors, you isolate the systems' grounds. This seems to fix the problem.
To Apple's credit, after looking for some information on the audio specifications of the MacBook Pro, I found in the developer's section the Audio Developer Note for the MBP in which the following was stated:
"For best results, equipment plugged into the line/headphone output jack should not connect the audio ground to other grounds, such as the chassis or "green-wire" ground."
I hope this helps others.
