• Problems with dual monitor: VGA is out only work

  I have a dual monitor card galaxy geforce gf430 who worked on Sunday night before putting the computer to sleep. When I came back Wednesday on the side of the hdmi/vga/dvi vga worked the only possible output. After having checked all the settings and the cables and update of my computer, I had more than one screen. I went out and bought an asus hd 6450 and installed in the hope that I would have my screen. no luck I checked all the settings again and nothing. I ran the program provided with the card and so far nothing. It is not even read a different location for the screen. can someone please?

  I took the liberty to do a little research on the ASUS HD 6450 map.  Are - what you got to get the ASUS HD6450 silent and low GPU or the bigger one with the fan?  It might be possible that those silent will not support Eyefinity technology since it was modeled for the home theater PC use.

  I noticed that the model with the fan on the radiator mentions he is compatible Eyefinity, while the silent model does not work, but it allows you to choose between a VGA, DVI or HDMI port, but do not use them simultaneously.

• questions of two monitors

  Hello

  I have a hp pavilion model s5310f with windows 7.

  I am trying to connect two monitors to my system using a powered by usb 2 port VGA splitter.

  the problem I encounter is that the computer is not picking up on the fact that I have to the monitors hooked up.  When I go to appearance and personalization - poster - resloution that's not recongize there are two monitors attached to the top of the screen. Assumed to be an element of the line indicating 'several screens' and it isn't here. However, two of them work they reflect just between them. Could you please help me with this diagnosis? I monitors, separator or a problem of outdated system?

  Any help would be wonderful, because I am at a loss.

  Thank you

  Cory

  Both of the above positions are correct. Your form (here) show that you have only one video output.  In order to have two screens you want (extended mode), you will need to do this: adding a monitor using a HP USB graphics card.

• Recognition of two monitors in Vista

  Just got two new monitors and thought their hanging would be easy.

  When I right click on the desktop, click customization, and then click on display settings, the dialog box indicates that there is a single monitor. I clicked on advanced settings and went to the driver tab, click graphic properties, under display devices and display settings it recognizes only a monitor. Don't know what to do to launch Vista in gear and do something more hanging there.

  Have a VGA splitter in the destop, both lines VGA in this Dispatcher. But Vista is not recognizing that there are two monitors attached. I rebooted the system, played a bit with trying to install different things and read countless forums. I found one, but it was completely useless.

  Hello

  With a Standard VGA Splitter, you will get the same screen on both monitors.

  You need a device such as a Matrox DualHead2Go, or a video card with dual output, or
  two video cards compatible to get two monitors to show separate screens.

• Cannot use two monitors.

  Original title: double monitors - we're missing!

  I have two monitors running on Win7 which worked very well.  All of a sudden the display on what was my main screen erased.  I tried to reinstall the monitor; spend the 2 monitors to test the VGA adapter (both monitors work), etc.  Nothing has worked.  So, I reinstalled the driver for the VGA card.  Hop, my screen on the 2nd monitor is back... until the computer went to sleep, or even when the monitors sleep.  Once the monitor turns off (whatever it is, or if I turn it on manually off & turn), it cannot be detected.  He comes back if I restart, but it's a huge time drain if I get called there long enough for the monitors to cut or the computer to sleep.  I currently have both to "never", but they stop even if they have no value.  This used to happen, but I don't know why it's happening now.  Help, please!

• HPE HP8 1360t DVI connections and two monitors

  I recently bought a new HP8 HPE 1360t directly from HP.

  I finally got around to get set up last night. I like almost everything about it, EXCEPT to try to figure out how to make it work with two monitors.

  Before buying, I contacted HP sales to confirm that this model could support two monitors in extended mode, which means that Office spans both monitors, giving me two times the workspace.

  I have two monitors (1908FP) Dell that I got as part of a severance package from my last job (Yes, I know what you think) and down them as two monitors with the office in extended mode. They have both connected via DVI to a MOLEX splitter. They seem to be of DVI - D Single Link.

  At the back of my new computer, there are three DVI ports:

  -one on its own and it is DVI - I Dual Link (photo below)

  -both grouped together and on the side. one looks like DVI - I Dual Link and the other DVI - D Dual Link

  When you configure the workstation I naturally just assumed to connect all the cables DVI mail of my monitors for each of the two DVI ports on the side. Nothing happened.

  I removed then each of them to test it on its own. Still nothing.

  Then I plugged into the port at the top, and it worked. But it has only a single port.

  So I went back and tried the other in each of the two and went to the panel display and but it does not recognize the second monitor.

  At this point I don't know what to do. They told me this computer supports two monitors, but I don't see how it's done if neither of the DVI low ports to work.

  Is there anything else I should do? Or have I not those who simply do not work?

  I am running Windows 7 family Premium 64-bit (Service Pack 1), Direct X 11, and the graphics card is GeForce GT 630.

  If it means anything NVIDIA control panel says my card and monitor are HDCP and it does not find the second monitor when I use setting up the functionality of multiple screens.

  I would be very happy for any help and advice.

  Thank you.

  This model uses a card mother IPMMB-FM (Formosa). The built-in rear I/O below;

  

  (5) - DVI - I (digital and analog output) and DVI - D (digital only)

  When the computer is equipped with a dedicated graphics installed in slot PCIe x 16 card, this motherboard integrated DVI outputs are disabled. The only connections that you can use are those on GT630 discrete graphic card. This card must have at least a DVI and an HDMI output. Please post a photo of the back of your computer, centered on the graphics card. You may need to use a HDMI-DVI adapter to connect the second monitor.

• Two monitors, prompting connected and trying to get to work

  My friend and I try to connect two monitors on his desk and we have the computer connected properly, but the screen is not any kind of signal to the computer (it won't turn on, just has a black screen or say in power saving mode). The main monitor works (of course, as l write this) it connects to the NVIDIA DVI (a video card installed) card, and the second monitor is a VGA. The second monitor we want to plug that we want to use on the OLD card came with the computer video, and we have the ports for it. However we are unable to operate, and it is quite frustrating. We have tried to update the software, but we think he may have disabled the second video card without meaning to, and we know many things at this point:
  1 can I use two monitors to two different computers and use them to do different things (for example use it to surf the two different sites with two different keyboards/mouse, or play two different games (our intention is to play WoW the computer off) in this way)?
  1a. If Yes, can someone please a link to a site that would be easier to read and understand? (We were already posted some, but they are confused or just say the same things and do not work)
  2. how to reactivate the video card should it be disabled? Once again, the simple steps please.
  3. can we use two separate video cards to run two different items on the computer, or would both forced to run out of the video one card?
  3. If so, is there someone who can explain how to bind a monitor with a video card and not the other?

  Hi warpedchocobo,

  Windows detects and identifies each monitor and projector that you connect, and applies the video settings that are best suited to each display. When you connect an additional monitor for the first time, you can choose how you want your desktop to appear on the screen. In addition, Windows collects information about the video capabilities of the additional screen, including the size of the screen, the screen resolution and the color depth.

  On Windows Vista, older XPDM drivers still work and the behavior of multi-monitor with XPDM drivers has not changed, because the operating system uses the existing graphics stack.

  However, the Display Driver Model WDDM (Windows Vista) brings fundamental changes to the management of several graphics cards and external displays. This includes a new restriction, because WDDM drivers do not support multi-monitor «multicard and heterogeneous» implementations

  See the links below for more information.

• Windows XP loses two monitor settings and returns to the single monitor after to be identified only by the windows... No reboot is

  To begin with, I am the HelpDesk of the company and our users are running Windows 7, Vista and XP. The problem will occur randomly on most XP and Vista systems.

  I'm beginning to believe that it is a computer problem to the extent of the material or something of this nature.

  For now, I swapped the computer and now the question is not fooled by the user.

  But in general I wanted to know why this happens. They will be blocked (not a stop) their computer to take a lunch break and when they return to log in order to return to work. They work on two monitors and for some reason, as the settings go back to the single screen...

  Why this keep happening? Help, please?

  Either way, I don't think it's a driver problem... Because I just run images on hard drives of all application users run and the problem occurs randomly.

  Thanks in advance for your response...

• Laptop with docking home & two monitors... need to get laptop to work after the withdrawal of the docking station

  It drives me crazy.  I have a work Dell laptop connected to a station host and two double monitors. It works very well at the office that I work mainly on two large dual screens.  When I remove the laptop from the docking station and bring home the computer starts and displays a portion of my homescreen (like an extended display).  But I can't do anything else with it. I can't access my files or anything.

  What I want to do now that I'm home with my laptop is to redo the settings so that the laptop is my main screen.  The normal methods of right click and change the screen resolution do not work because I can't access my Windows start tab.  Any ideas...

  Thank you.

  Hello

  Thanks for posting your query on the Microsoft Community.

  I would be grateful if you can provide us with the following information to determine the root cause of the problem.

  1. What is the number and model of your computer and the graphics card?

  2. Have you tried to monitor primary as secondary and vice versa?

  3. All device drivers are updated?

  Windows can detect automatically that an additional screen. If you connect two or more monitors, you must manually designate the primary display, arrange your desktop, and apply display settings, such as color depth and screen resolution. So, the next time that you connect these monitors, Windows automatically identifies the primary display and applies the settings that you previously specified for each additional display.

  Try the methods mentioned below and see if it helps.

  Method 1

  If you haven't tried Exchange monitors so I suggest you to try and see if the problem still occurs.

  To change the settings of two monitors you can consult the links below:

  Note: This link is also applicable for Windows 7 .

  Method 2

  If the problem persists I suggest you to update the display drivers. As the display drivers for two monitors are not the same, so try to update and check the status.

• Menu Spry - only works the first time, or two

  I've implemented a Spry menu, according to the book (a half dozen or more main menu items, a couple of those, with three elements of the submenus - of course, it is a model applied to the relevant pages). It works very well in live pages on the web. Then after one or two openings of the menus, the lower two-thirds of the menus stop working! The menus of one or two albums always do their thing, but the rest of them no longer open the linked page. This has happened at the opening of the page on Mac Safari and IE7 Windows.
  
  At least once, clear the cache on Safari fixed temporarily - then the problem came back...
  
  Is this a known issue? Are there workarounds?
  
  Very well, thank you in advance! I need to make this page work, and this problem has me buffaloed.

  Well you helped me a lot, thanks

  Your insight on the code was right, and we had a bad page. Incidentally the model was not correctly updated until what we fixed another problem.

• How to extend to two monitors?

  I have a Macbook Pro that I bought this year. I want to connect it to my KVM DVI switch for two monitors. It will work with a bolt of lightning for two adapters to DVI ports? If so, any recommendations on what card? If option 1 is not possible, I guess I need two crush on DVI adapters. However, without worrying that we I get, I need to work in extended mode and not just mirroring. Is this possible with the MacBook Pro?

  I'm looking at present one this one on Amazon. Any recommendation is also appreciated.

  with the exception of the Apple ThunderBolt display NO display use ThunderBolt directly. They all pick up a subset of the ThunderBolt signals off the same connector, called Mini DisplayPort. Mini DisplayPort and its twin full size are "next generation" display interfaces.

  DisplayPort family attribute this and display-decision makers interface wanted to for a long time. Refresh 'heartbeat', 60 to 100 times per second is GONE. Only changes are sent in most of the time. The display must have an internal display buffer. Talk about framerate for DisplayPort has no meaning.

  The signal levels are very low, but use differential driver (or push-pull) circuits to very good noise protection.

  If you choose to convert to "legacy" display protocols, you can do it on a limited basis, with constraints. Long cables or more than TWO screens "legacy" will lose the signal strength and must be stimulated with ACTIVE DVI adapters, usually around US$ 40, who re-pilots to signal them upward.

  Using DVI screens larger than worms 1920 wide requires a Dual-Link, much more complicated and expensive adapter.

• Portege Z30 16 GB with high speed Port Replicator III and two monitors - resolution

  I have a Portege Z30 with 16 GB of Ram, connected to a Toshiba high speed Port Replicator III which is connected to two monitors running in mode extended.

  The monitor attached to the first section of the video is 1920 x 1200 running.
  However the second monitor is only show support for a maximum of 1280 x 1084.

  The monitors are identical, and both are connected by DisplayPort cables.

  I tried to lower the resolution and save the settings on the first monitor to see if it offered options on the second monitor, but the options remained the same.

  At this point, I have narrowed down to 1280 x 1024 so that it conforms to all the monitors but would like to a plus-res solution.

  Does anyone know if there is a fix/work-around for this?
  If this is a hardware limitation, has anyone tried a USB 3 to DisplayPort adapter in a similar configuration?

  Thank you!

  At the same time using two displayports?
  I wonder how it is possible, because of my knowledge it is not possible... as far as I know the Port Replicator III supports two DisplayPorts but you could choose and use one of them...

  In any case, you can use both with a lower resolution, I guess that this problem can be caused due to incompatible display drivers.
  I suggest you to uninstall reinstall or update the display drivers and check if it helps
