Dual monitor cloning size issue

ive always had trouble selecting a size for my macmini on my 40 inch tv, but now i want it to work as a dual screen moniter that clones onto a 4:3 square screen, basically i need it to fill the wide screen, and have some kind of black bars on the top and bottom of the small moniter, it make make it harder to see on the small moniter but i dont mind, can some one help me? thanks

I'm confused, it has 2 monitor ports, a VGA port and a DisplayPort.
If you are not using a DisplayPort capable monitor, which many are not, you do need an adapter for that port, ie. DisplayPort to DVI.

M91p dual monitor graphics card issue

Hello,
My work recently purchased a Thinkcentre m91p - model number 7052C9U without realizing that it was not dual monitor capable. We're a small business and have no IT division so it is up to me to solve this problem for myself.
Ive been doing some research via google but have not come to any real conclusion about which graphics card I should get that is compatible and will allow me to use 2 monitors.
Can anyone here direct me in this regard? Im looking for a quality yet inexpensive graphics card, compatible with my model of Thinkcentre, that will allow me to go dual monitor.
Thank you in advance,
Brian

T420 Intel HD 3000 Dual Monitor Mini Dock Issue

I have a T420 with Intel HD 3000 using a Mini Dock, attached to Two external Monitor one VGA and the other one DVI, the problem is that the DVI won't work simultaneously with the VGA, after update the Intel HD driver to the last version available 9.17.10.2843, both monitors works simultaneously, but If I Reboot, Hibernate, Standby or Undock, only the primary monitor (VGA) works and the Extended (DVI) stop working.
I tried using another video driver version and updating the BIOS but not luck, Does any one know if there is a solution for this issue???

Are you trying to keep the internal display on when you connect to the external monitors?

Dual monitors: window size too large when opens in smaller monitor.

I use Windows 7 with two monitors. When I open Firefox directly from my desktop, it opens on the larger monitor, and the window size is just fine. But if I click a link from an email, Firefox opens in the second, smaller monitor, and the window is too large for that screen.
Please help me figure out how to either (a) make Firefox open with a smaller window; or (b) make Firefox open on the primary, larger monitor.

oh, forgot to say Mavericks 10.9.5 running on the mac pro..

I get that ^^: looks like the VGA screen IS 1280x1024, but for some reason ratpoison thinks it's 1280x800 (all open windows have that size).
this does not happen in DWM, but should work ok with ratpoison too...so I'm guessing it's a wrong setup on my part.
Enabling Xinerama in xorg.conf doesn't even start X at all...it segfaults
What other steps should I take to makea working dual monitor environment? I would like to have 2 X screens btw (my laptop to be screen :1 and CRT screen :0 (the default))

Scratch that..it was working..but silly me forgot to use ":nextscreen" in Ratpoison..so the windows would open at 1280x800 since the damn thing though I'm still on the first monitor

Server 2012 Dual Monitor Issue - Can't Get it to work properly.

I have a HP Proliant ML310e that runs Server 2012 R2. It came with an on-board VGA graphics adapter, that was using a Microsoft Basic Display Adapter driver and working fine.
Needing to run dual monitors, I contacted HP and purchased a Nvida K2000 PCIE graphics card. I installed it using their latest drivers and rebooted, making sure that the new PCIE card was enabled in the BIOS.
While booting, the server actually now displayed on the new 'second' monitor connected to the newly installed Nvida card. When I actually logged in and went into the display properties, it was only detecting the new display - I couldn't even force detect
the original display.
Also, when I go into device Manger, it now only shows the Nvidia graphics adapter - no longer shows that the Microsoft Basic Display Adapter is present.
Any advice on how to get dual monitors to work on Server 2012. I did try the Windows/P Projector display, but that did nothing.
Thanks,

Hi,
You should check your BIOS settings - some motherboard will disable onboard display card once a PCI(E) card is plugged in. This is a hardware settings issue. If HP support is available, ask them for detailed configuration steps.

Dual monitor color issue - oversaturated image in CS4

Hi, I wonder if you can help. I found people having similar issues, but never seen an actual answer, so your input would be greatly appreciated.
My set-up:
MacBook Pro Dual Core intel based 15.4 2.6GHz running OS X 10.5.6 - also my primary display
HP LP2475- secondary display
CS4
Both monitors were calibrated using X-rite Eye-one LT (each with a separate profile)
I've tried calibrating each monitor 3 times and still get the proble,
My problem:
Running in dual monitor mode in bridge or safari/firefox- no problems at all: almost consistent colour between both monitors.
When I open the images in Photoshop CS4, they look fine on my MacBook screen, but when I drag them over to the HP the color is grossly oversaturated - especially in the red. What am I doing wrong? (in fact on the HP monitor, the color looks perfect in bridge but super insanely saturated in CS4)
Does anyone have a clue on how I can fix this?
Thanks!

You say your running 10.5.6? Why haven't you updated to 10.5.8?
FWIW, I never had color issues under 10.5.X, however I have since upgrade to 10.6.

NF750 with Dual Monitors using Internal Video issue

I'm currently trying to get this motherboard to output using both the builtin DVI, and HDMI for a dual monitor setup.
Unfortunately what is happening is, first, while in windows with current output to DVI, connecting the HDMI, the monitor is not detected. When booting up with the HDMI it will be detected as long as the DVI is not plugged in. If both are plugged in, neither will show a screen.
Has anyone else had this issue and managed to fix it?
I have also updated to the latest nforce drivers, and bios.
Thanks for the help

I don't believe its possible to use both digital outputs (DVI and HDMI) simultaneously.

Screensaver issue with dual monitors

My screensaver has recently started acting up. It's sort of a minor blip, but it worked before and now it won't. Here's the issue: I have dual monitors (Intel imac, running Leopard, with a Viewsonic 20" lcd running in extended desktop mode). I use a "smart" album from iphoto as a screensaver (iphoto 08, v7.1.5). I've been using this particular smart album for several months as my screensaver and it's worked fine. How it used to work: when the screensaver activates (either by time or by hot corner) both screens would draw photos from this album and randomly scroll, zoom, and fade them across each monitor, independently but simultaneously. It's worked like this flawlessly for years, with several different iphoto albums. Now, I just noticed that the second monitor does not find the pictures. A message on screen "looking for pictures" appears on both monitors, as normal, but instead of both monitors going to screensaver, only the imac starts, and the message "looking for pictures" stays on the other. What's weird is that if I run the screensaver in test mode, it works like it used to (both screens work independently and simultaneously). And if I switch to one of Apple's supplied screensavers, both screens work as well. But any iphoto album no longer works properly. I don't understand what has changed. I just recently ran an upgrade (Software Upgrade, a week or so ago) but it seems like it worked normally since then, and I don't believe the upgrade was a major one or had anything to do with iphoto. I just noticed this problem today. I've tried restarting the machine. Same issue. Any ideas what could be causing this minor, yet annoying, glitch.

I had this same problem arise after installing an iPhoto update in late January. I contacted AppleCare and the problem was escalated to a Product Specialist. The Product Specialist contacted Apple Engineering and Engineering 1) replicated the problem and 2) confirmed that it's a bug.
So, Apple is aware they have a bug and we look forward to a bug fix -- at some point in the future. I hoped the problem would be fixed with the next iPhoto update but a major update came out today and the problem remains. I don't know if there's any way to know whether the problem is an OS bug or an iPhoto bug but either way we have to wait until it reaches the top of the pile at Apple...

Yes, only my boss informed me that they have to be display ports, he didn't tell me why.
I'm unable to buy from ebay or craiglist either & my local vendor doesn't have any in stock.

Quite a mouthful I know! but I need these specific graphic cards, ideally with next day delivery:

HP Zbook dual monitors issue - Intel HD Graphics Family ! in Device Manager

I have upgraded to Windows 10 x64 last week and I was using dual monitors. I discovered one of the monitor has stopped working and when I chekced in the device manager, one of the 2 display adaptors has got an exclaimation mark beside it and says: Windows has stopped this device because it has reported problems. (Code 43) I have tried uninstall and installing it to no avail. Anyone has the same issue? Is this a driver issue? Thank you.

Dual Monitor issue - Open file to 2nd monitor?

I have a dual monitor setup in Windows 7 and like to work with all the tool panels and PS main window on the left monitor and the photo open full screen on the right. I have tried saving the workspace with the image open full screen on the right monitor, but no matter what I try, everytime I open/re-open a file, it loads on the left monitor behind the tool panels. I then have to press F5 to mnimize some tool panels, then grab and drag the image window to the right screen. Then I have to press the F key to maximize the image window and F5 to restore the tool panels. This is my routine everytime I open a file. There has to be a better way! I have tried things like reseting to the default workspace, moving the PS window and tool panels to the right screen, but it seems the placement of a newly opened document must be hard-coded to open in the main PS window, no matter what the user has setup.

Yeah, this is annoying as hell.
In CS3, if you dragged an image to your second monitor all subsequent images would open up there. I'll leave my snarky, sarcastic comments about the wisdom of this new "feature" for another time. What might end up working you is putting the image on your monitor of choice (along with the app frame and the menu bar) and dragging the tool palettes to the other monitor. That's what I'm doing now and it's taking some getting used to but fortunately, once you drag over the tool box and the layer stack, everything else tool-related seems to open up there OK. The images stay on the other screen (for the most part).
All things considered, it still sucks... but when you only have one choice, the decision is easy to make.

Imac dual monitor primary monitor issue

This is driving me nuts and I must be missing something...
I have a 27" Imac (all-in-one) fully loaded with all the software I need (which I will call my old machine). I then bought another iMac but a newer one (I will call my new machine) again loaded with the software I need. I linked them together with the correct cable and the dual monitors worked great - my old machine being the primary display my new machine being the external display. It worked great for about 2 years but yesterday I thought I would like to switch the machines around so my new machine is the primary machine I work on (because it has a faster processor and some newer software) and my old machine will be the external display.
I just cannot do it!!! The arrangement tab in the display only shows on my old machine and no matter what I do with the screen and menu bars it is always the old machine which is primary with the older software.
I have tried unplugging each machine in different sequences, rebooting several times with always the same result - my old machine is the one with the Arrangement tab and therefore this is the primary display (with the older software).
Can anyone offer any advice on how to resolve this please.
Thank you in advance.
Tony

AMD/ATI driver problems on a Dell laptop with attached dual monitors

I have a Dell Precision M4800 laptop with a docking station for two additional monitors. I'm shooting for a "big desktop" setup, with my laptop display and the two external monitors forming one large multi-monitor X screen.
When deciding which video driver I'd need, I did the usual:
$ lspci | grep VGA
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Venus XT [Radeon HD 8800M Series]
Which is weird, because the M4800 isn't shipped with 8800M cards. Rather, it's shipped with the AMD FirePro M5100 Mobility Pro (see above link) (also, too many "Pros", AMD...).
I tried the open-source driver, but I couldn't get both my external monitors working in tandem, so I went with catalyst-test, since the non-beta version of the proprietary driver doesn't support the 3.13 kernel (or my alleged 8800M series card, for what it's worth).
My display setup using catalyst-test is still far from ideal. My dual (horizontally adjacent) monitors reset to cloned/mirrored desktops after every reboot, and my machine refuses to show three monitors (dual monitors + laptop display), even with the 2GB of dedicated RAM in my graphics card (see above M4800 link). There's other miscellaneous annoyances as well.
Using hardinfo, I see that my VGA driver thinks it only has 256MB of RAM... which doesn't align with the M4800 specs. Is there a way to change this value?
Just today, I found the catalyst-firepro driver, which I think might be the correct driver for my laptop, at least given the specs on the M4800 from the website.
There's also the option of not using my AMD card at all, and just using the Intel graphics on my laptop. (I had to disable hybrid graphics in my BIOS to get any AMD-specific drivers to work). I'd like to steer away from this, due to the performance loss, but I'd be willing to make the change if the pros outweighed the cons.
As I see it, I have a few options:
AMD/ATI open source driver: Can't seem to get two monitors working, much less three...
catalyst-test: Any two monitors will work together, but not three. Other annoyances.
catalyst-firepro: Have not tested yet.
Intel open-source driver with AMD card disabled: Have not tested yet.
Can anyone who has had similar issues and/or hardware offer a best course of action which has worked for them? I know we're supposed to avoid "opinion" questions, but I think this is grounded enough in the scientific method to merit some helpful responses.
Any help is appreciated.
Thanks!

The last option to me is screaming catalyst-pxp at me, because that's one of the few options if you have integrated graphics and a discrete graphics card.
Let me get this straight: Can you disable the either or both of the Intel/AMD graphics in the BIOS settings? If so, but don't want to disable either, you might want to look at the hybrid graphics section of the wiki.
I know about powerXpress and I think I'd like to avoid it. My experience with hybrid graphics on other Linux distributions is that it's rather unstable or just plain unsupported. If someone can convince me otherwise, given their experience with hybrid graphics on Arch/Linux, I might reconsider.
I'm fairly certain I can enable either of my GPU's separately, but I'll have to check for sure next I reboot my PC.
The last option I mentioned because I thought the Intel drivers might be more robust than the AMD drivers, which have don't have a sterling reputation when it comes to supporting Linux (compared to nVidia anyways, who I know in the past have had good Linux support).

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)
