Dual monitor solution!

Ok, so I was having the same problem as everyone else, with cs4 and 5, the document window always opened in my tools window. I would have to drag the image to my second monitor which was a pain. Everyone said check your drivers vid. card and whatnot. So while meditating with some wine, I got to thinking that the problem started with cs4 which is the first version where you could dock windows together. And when I opened an image, it always docked with the main window.
This is how I fixed it:
Edit>preferences>interface...uncheck open documents as tabs!
Done...
This should also work for cs4.
God I feel stupid.

There are a couple of ways to do this.
If you need both displays to be highly responsive and quick, one of the Matrox DualHead2Go boxes will enable you to connect both displays to it and the Matrox box to your MBP. Which Matrox unit to get depends on which MBP model you have, and there are some differences in maximum total resolution from one Matrox model to another.
http://www.matrox.com/graphics/en/products/gxm/dh2go/
If you can get by with one of the displays being less responsive than the other, connect one to your MBP's video-out port and the other to a USB port, using an adapter like this:
http://eshop.macsales.com/item/NewerTech/VIDU2DVIA/
With a Matrox adapter, both external screens will form a single extended desktop — they can't both show the same image. With a USB adapter and a direct video-out connection, I think you will be able to choose whether the external screens display the same image (Mirrored mode) or form a single extended desktop.

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.

EVGA Plus:

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.

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!

Dual Monitor Setup S5-1070t

I am trying to connect a second monitor to my HP S5-1070t desktop It has an AMD Radeon HD 6450 graphics card installed which was ordered with the computer. This card has a DVI and an HDMI port on it. My main monitor is an HP 2011x connected to the DVI port on the card. I am attempting to connect a Compaq Q1859 monitor to the HDMI port using an HDMI to VGA adapter. I updated the AMD Calalyst Control Center to Version 2013.0328.2218.38225. When I run Detect Displays it only shows my HP2011x display.
I scanned through the previous dual monitor questions but I didn't find anything related to my problem.
Any help would be appreciated.
GL Rowe

Here are the original specs and configurable options for your HP Pavilion Slimline s5-1070t CTO Desktop Computer. Here are the specs for your HP Pavilion 2011x WLED backlit monitor and your Compaq Q1859 Widescreen LCD monitor. According to the specs, the 2011x monitor supports both DVI-D and VGA video input connectors, while the Q1859 only supports a VGA video input connector.
You stated the s5-1070t with HD 6450 graphics card supports both HDMI and DVI video outputs but you didn't indicate which type of DVI it is. DVI comes in DVI-I (both analog and digital), DVI-A (analog only), and DVI-D (digital only). Please review this Wikipedia DVI article to determine which type is on your card or post a photo of the ports on the card.
You also indicate you are using a HDMI-to-VGA adapter. There is no way way to "adapt" a digital HDMI signal into an analog VGA signal short of using an expensive digital-to-analog converter. These converters normallly run in the hundreds of dollars and don't always produce good results. Until the monitors are correctly connected without this "so-called" adapter, the computer is only going acknowledge one monitor.
If, and only if, the Radeon HD 6450 supports HDMI and DVI-I, you can connect both monitors as follows and both monitors will work;
Computer ---> HDMI-to-DVI-D (digital) cable ---> HP 2011x Monitor
Computer ---> DVI-to-VGA dongle ----> VGA cable ---> Compaq Q1859 Monitor

T510 dual monitors no longer working properly

I have a T510 running Win7 64-bit. For at least 3 years, I have had the same dual monitor setup (2 DoubleSight DS-1900S) running off my minidock with the laptop closed. The rgith monitor is the primary, running off the DVI port, while the left uses the analog port. I was away for a week at Scout camp, powered on the system once while I was there, and when I came back to the office, my monitor setup started failing.
Specifically, the right screen is active but it no longer displays the signal being sent to it. When I powercycle the screen, I can see the display for about a quarter of a second, then it goes blank. When the problem first started, I could cycle it about 20 times and eventually it would stay on, until I left the unit overnight and it went to sleep, at which point the probelm started again.
Sounds like a wonky monitor? I have a backup set of monitors that I swapped in, and had the same exact problem, so that appears to rule out a mechanical defect. More fun facts: I can only use the laptop screen as a standalone display. I cannot get the multidisplay control panel to open, even though my left screen is powered up. However, one of my programs that normally launches to my right (main) screen will still launch, but not to my laptop screen. It really wants to live on my right screen, even when that screen is not powered on (I can close the program by accessing the icon bar at the bottom of my laptop screen).
As you might surmise, this is an extremely frustrating situation. I have gone on many trips with this laptop, and each time I returned, I either plugged it into the minidock with no issues, or I had to readjust my power settings briefly to get it to work as per usual. This time, I have no clue what went wrong. Suggestions?
Solved!
Go to Solution.

I have not changed any software or drivers (knowingly), and I had already checked the cables to make sure they were all tight, so off I went to ransack the house to dig out the spare cables. DVI cable? no change. Power cable? no change. Converter cable - OMG!!!! IT WORKS!!!!
Thank you SO much! I could have sworn this was a software issue, never considered a bad cable or power unit.
Both monitors are working properly, left-to-right scroll is working properly. Now all I need is to figure out how to get all my icons/shortcuts back onto the right screen...

HP paviliion p7-1423W Dual Monitor

I have this HP pavilion product and wish to run dual monitor on it. It has two display ports DVI-I and DVI-D, it came out of the box with a DVI-I to VGA adapter, which I am using for my main screen, I recently bought a DVI-D to Analog VGA(i have a HP v17 which is analog) I've changed the only possible setting in my BIOS that I can find that deals with display was labeled something about VGA i enabled it and still my screen displays "No Input Signal", I've tried this DVI-D port with my main monitor and it does the same thing. I've looked in the Intel HD Graphics GUI the only screen showing up is my Dell(main) the only other option for display is "Intel WiDi" which i dont have a wifi display. Anyone have any insight on how I can get dual monitors working. According to the user manual and the reviews I've read about this product it's able to handle two monitors so I dont see why I cant get it working.

3 - DVI-D (digital only) 4 - DVI-I (digital and analog)
==========================================================
Looking at ports #3 and #4, notice that port #4 (DVI-I) has "cross" with four pins surrounding it while port #3 (DVI-D) doesn't have those four pins. Please see Wikipedia article entitled "Digital Visual Interface (DVI)" for more information on this subject. From the previously mentioned article;
"This is a passive DVI-to-VGA adapter. This adapter will NOT work with a DVI-D output. It requires a DVI-I or DVI-A output to get the analog signal to a VGA input (even if the adapter looks like a DVI-D). An expensive active converter would be required for a DVI-D output to VGA input."
Note that an expensive active converter may have video image quality issues, which could impair the value of this device versus the cost. Based on the specs, both of your monitors support VGA only. You have several options to resolve your issue;
1) Buy an active DVI-D to VGA converter (costly with possible poor image quality)
2) Buy a USB-to-video adapter such as an eVGA UV Plus+ UV39 (not good for gaming or high-bandwidth content video)
3) Purchase a new video card that supports your desired configure (may require replacing the power supply)
4) Purchase a new monitor that supports at least one DVI-D digital input (depending on size, may be expensive)

Dual Monitors on Late 2011 17" MacBook Pro

Hello:
I wanted to do a dual monitor system for work; I have two 24" Apple Cinema Displays -- as you know they come equipped with a Mini-DVI I/O along with a mag-power, and USB 2.0 I/O. I found a Matrox DualHead2Go Digital ME [http://www.matrox.com/graphics/en/products/gxm/dh2go/digital_me/] as a possible solution, the issue I am having is that Apple has not made a DVI-D I/O on a Cinema Display since the 30" Display many years ago. The Matrox product is new, and touts that it is Apple friendly but I cannot (for the life of me) find a cable/converter to go: Mini-DVI (female) to DVI (male) to make this work. So, does anyone know if this cable exists, and if it does, where can I get it? Or, does anyone know if someone makes a product that will allow dual monitors (NOT stretched desktop) that will go Thunderbolt/Mini-Display Port to Mini-DVI so I can get true dual monitors on my MBP so I can run it in clamshell mode on my desktop?
Just as a FYI, I am NOT interested in going to a USB solution as the refresh rate and resolution would not be good enough to warrant consideration.
Thanks in advance for all of your expert help and opinions!

The only way that you can use both a SSD in your drive bay and another hard drive is to install the hard drive in your optical bay. If you're willing to give up your optical drive, OWC sells kits to do just that.
Then you could use your external drives for data storage & backups.
Is this a workable option?

Dual Monitors Windows 7 Problems

Ok, this problem is getting really annoying and I think its a problem with windows 7 itself and not my computer.
Basically I have a dual monitor setup with the left hand monitor as my secondary and right hand monitor as my primary. Whenever I have an application with any graphics on it at all such as a progress bar on my left hand monitor moving windows around becomes laggy and juddery, yet this doesn't happen when the graphical app is on my primary monitor!

Updating to latest drivers
Upgraded system memory from 2GB to 4GB
Installing 64-bit version
removing sound card and re-installing windows from scratch
upgraded my PSU
Thanks for your help!

(Latest update) This is the best I can do to alleviate the problem, and does reduce its severity immensely, but I found myself still noticing some slight playback glitches in videos on my second monitor which probably also translate to anything else with movement. I have tested with a panning scene in one of my videos and there is a subtle micro-stutter on my second monitor which I can find no way to fix. This doesn't occur if outputting to a single display, one or the other, nor does it occur when playing the video on my primary monitor in a dual-monitor configuration. Note that when I say "primary monitor", I am not referring to the monitor Windows has marked as primary, but my actual monitor rather than TV. In a dual-monitor configuration, this micro-stutter will only occur when playing video on my right monitor (TV), regardless of settings or which ports the monitors are connected to on the GPU. The micro-stutter occurs with no relation to the activity on the other screen, as it can be completely still. I can confirm the micro-stutter does not occur at all with Desktop Window Manager (Aero) disabled. In short, this is a nightmare.
(Note that this micro-stutter is equally replicable in the 182.50 (WDDM1.1-less) driver, meaning there is no way to solve it other than disabling Aero or outputting to a single monitor.)
I think I've solved the problem.. for me, anyway. I've divided this into short answer and "long answer", which is closer to a stream of consciousness in some ways, as I found out about Force10Level9 as I was writing.
The short version:
I've found some registry keys which seem to have fixed the problem for me. I haven't experienced any side effects, but use the tweaks at your own risk!
I don't know exactly what they do. This comes from a lot of.. experimentation. I believe FrameRateMin tells the Desktop Window Manager that it's crucial to try to keep the framerate at or above the value specified (more details below), and Force10Level9 sounds like it forces DWM to use DirectX 9. I'm fairly certain about the former, not as certain about the latter, but together they do wonders.
You can view the fix below. You can then save it as a .reg file and import it into your registry. Restart the Desktop Window Manager service or reboot to see the changes.
Fix: http://pastebin.com/FFDbubw9
Undo: http://pastebin.com/zA8CJY06
(P.S. Just ran a FurMark test between fix applied and no fix. No difference in performance, with an inactive secondary monitor. I also noticed no difference in Physical Memory usage as reported by Task Manager. YMMV, let me know if you have any side effects.)
(P.P.S. The screen fade that happens when you log in/out is just as choppy as before (or if it wasn't choppy for you, that shouldn't have changed). Oh well, how often do we see that thing, anyway? :))
By the way, it appears 10Level9 is Windows 7's emulation platform for running DX10 on DX9 hardware. It's reported to be at least a 0.5x performance hit, so it's surprising that it actually makes Aero run better. If this article is anything to go by, Force10Level9 makes Aero run exactly the same as it does with older WDDM 1.0-only drivers like 182.50: http://www.techarp.com/showarticle.aspx?artno=637&pgno=1
The long version:
Well... I was able to do one more thing.
There is an undocumented registry key which allows you to fine-tune the Desktop Window Manager's scheduling. Unfortunately, all of its values seem to be defunct in the final version of Windows 7 we all use today... except one: FrameRateMin.
From what I gather, the Desktop Window Manager (Aero) carefully monitors the framerate it is able to achieve, and when it can't measure up to its own expectations, it will perform a "step down", or framerate reduction, and maintain this lower framerate for a given period of time (at one time specifiable with a registry value) before trying again at maximum speed.
I presume it does all this to keep things looking "smooth".
The problem is, in most cases, it doesn't help, and actually prolongs the stuttering duration. By "in most cases", I mean in every case it's happened in my personal usage of my Windows 7 computers.
So what helped me was setting this FrameRateMin value to 60. That way, the Desktop Window Manager considers anything under 60fps to be unacceptable and will not remain at a lower framerate for purposes of perceived smoothness. Thus, the stuttering will take up as little time as possible, making it nearly unnoticeable most of the time.
Keep in mind DWM shouldn't be having performance problems to begin with, but apparently in some cases, like with my particular hardware (desktop and laptop) and the latest NVIDIA drivers, it does.
Down to brass tacks. The registry key is HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\DWM\Schedule. The value is FrameRateMin, a DWORD representing the minimum framerate DWM will consider as acceptable. I set it to 60, but you can set it to whatever you want.
To repeat, this WILL NOT prevent Aero from ever getting below the framerate you specify; it simply prevents Aero from retaining a lower framerate after a stutter in order to give the illusion of smoothness (an illusion which fails).
I imagine the main reason it fails so spectacularly in my usage is because I watch a lot of videos which play back at 24fps. Such a framerate plays back terribly with a 30Hz refresh rate, which is what Aero would reduce itself to for extended lengths of time. Now, performance hiccups are minimal, but sadly still existent.
So this isn't a solution, but it does help. I am still uncertain of where the problem lies, considering GPU-Z shows graphics card loads to be as low as always when it's happening.
Oh, and I found one more registry value. This one is far more important. :) It solves the problem for me entirely, from what I can tell.
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Avalon.Graphics
add the DWORD value Force10Level9 with a value of 1.
I haven't noticed any side effects, just smooth performance.
Apply these tweaks at your own risk!

How to keep Flash in Full Screen on Dual Monitors

Hi,
I have a simple question. What should I do, to make my application (written in Flex SDK 4.5.1) staying in Full screen when I work in 2nd monitor - like Youtube and Euronews player (http://www.euronews.com/news/streaming-live/) ?
I don't know, how should I embed my application correct or add something to source code to make it work? My application is working correct in Full screen mode, I can use keyboard etc. but I'm not able to make this working - it's always going back to normal when it loose focus.
I have read many topics on this forum and internet, so I'm not interested in solutions like: http://flash-full-screen-multiple-monitor.clangen.com/en/ or .dll tricks like http://lifehacker.com/5419028/keep-flash-videos-in-full-screen-on-dual-monitors
If Youtube and Euronews is working with normal Flash (my current 11.9.900.117) there must be a way?
If someone can type code examples (like for a total dummy ), it will be great.
Thank you.

You'd want to ask in the Flex forum or Flash Professional forum, since you CANNOT edit ANY Flash content with Flash Player.

Dual Monitors on t430

I just received my new t430 and having issue with dual monitors. I am using the Intel HD 4000. I have it connected to a ThinkPad Port Replicator Series 3 (Type 4336). The docking station only support VGA connection. My new t430 only has a VGA connection on the side.
I have 2 monitors. One is connected to the VGA on the docking station. The other is connected to the VGA on the t430 itself.
While the machine is docked, Monitor #1 that is plugged into the docking station works, while Monitor #2 that is plugged into the t430 does not.
While undocked. Monitor #1 does work (obviously because undocked), but then Monitor #2 does work.
So I know both monitors are working and configured for VGA input. My questions is, why can't both work at the same time? While undocked, I can use laptop screen and Monitor #2 as a dual monitor. So I don't believe there is something wrong with the Operating System (Windows 7).
I used to be able to do this on my t420. With one monitor using VGA, and my other monitor using a DisplayPort. But looks like this model my company purchased doesn't support a DisplayPort (at least don't have the connection.)
Any help is greatly appreciated.
Thanks.

Thinkpad W520 with Minidock+ Series 3 - Dual monitors and USB fail sporadically

Hello there,
I wonder if anyone has experienced problems ThinkPad W520 and Mini Dock Plus Series 3 (Part number: 433830U)? I run into problems with dual monitor and USB devices.
For dual monitor setup, sometimes only a single monitor is detected, sometimes no monitors are available in the NVidia control panel. Rigorous display detection doesn't help. Disabling Optimus in BIOS doesn't seem to affect it. After I dock and undock couple of times, reboot, unplug the power cord, it seems to resolve and both monitors work fine.
Also, I run into troubles with USB devices (keyboard/mouse). Sometimes they are not detected at all, but if I plug them into different USB ports on the mini dock, they are detected and work fine.
For me this problem happens about 50% of the time when I dock... Any ideas, insights or suggestions are greatly appreciated. Could it be a faulty Thinkpad, docking station or may be both? I really to upgrade next time to W530, but I've been through so many problems with W520, so I don't know if it's a good idea...
Thanks so much.
Solved!
Go to Solution.

If system update isn't finding anything, and the system works just fine on its own, it could potentially be a faulty Dock.
It could be overloaded. Could you try testing the dock using just one monitor, and no keyboard or mouse, to see if you run into the same issue. It would still be a faulty dock, but it may be a potential workaround for the time being.

No signal to dual monitors on start up

HP ENVY Phoenix 810-170st CTO Desktop PC, windows 8.1
Two computer monitors, same models, one connected by dvi and one by hdmi. Upon start up they will randomly fail to display anything and will say "no signal, entering power saving mode". Sometimes unplugging one while the computer is still on will allow the other to start displaying and I can log in then plug the other in. Sometimes though I need to manually power off the computer, unplug one, power back up, log in and then plug the other in. Both displays work, both cables are fine, it just seems that occasionally when I power up with both displays plugged in neither will recognize it is getting a signal. Furthermore, once actually logged in I can reconnect the second display without a problem. Any ideas?

Hello naros89,
I have read your post on how you are intermittently experiencing display issues from your dual monitor setup, and I would be happy to guide you towards a resolution! To begin, I will need to ask you a few questions:
Has your computer completed all of its important Windows Updates?
Have you updated your HP drivers using the HP Support Assistant?
Is this an on-going, or recent issue?
What is the Product and Model Number of your two monitors?
In the meantime, I recommend following this document on Using Two or More Monitors with One Computer (Windows 8). This should help stablize your dual-display setup by alloting one of your monitors as a primary display, and the other as a secondary.
Please re-post with the results of your troubleshooting, as well as the requested information above. I look forward to your reply!

Dual Monitor/View problem......

I am having a problem running my dual monitors with my MSI gf4 ti 4200 128mb card...... i re-installed my drivers (i tried 30.00's and 30.82's) and they work fine, but once i reboot or change the resolution it'll show 4 monitors in my device manager instead of 2, and my resolution cannot change from 840x480x32 (used to be only 840x480x8 )....atleast i have 32 bit now.... but i think its cause the other 2 useless monitors are using up the resources for this settings, because when they arent installed it will let me go higher in resolution...... any experts here know anything about a fix or solution for all those monitors using "EXTEND MONITOR ONTO DESKTOP" without having 4 monitors showing? thx in advance,

ps.... i tried uninstalling the monitors but they just keep reappearing.....any MSI tech's know what i should do??

set "first display" - monitor. !

Dual Monitors w/ Macbook Pro

I have a MacBook Pro and would like to setup Dual Monitors. I have done a lot of research and really need an answer for this. I understand there are numerous ways to setup two external monitors, but I am looking for the solution that allows the computer to recognize both monitors as separate monitors. I am connecting to a 42" Panasonic Viera and a 23" Samsung SyncMaster. The TV is HDMI and the Samsung is DVI. I have looked at the Matrox Dualhead2go and cannot find if it is able to send separate signals, instead of turning both monitors into one huge monitor. Are there any solutions that anyone knows of? I know I can use a USB video card, but they are graphically inferior and that is not acceptable for my line of work (music production, sound design, film mixing). Any ideas?

Yu can use a Magma ExpressBox

with a NVIDIA GeForce 7300 GT

Another option is a Matrox Graphics eXpansion Module

They have resolution limits, though.
