Dual monitors won't work independently

Using win 7 ATI Raedon 4200 card. My second monitor displays only the primary desktop back ground. Followed all setup correctly please help

Vnyga, thanks but that's not it. The geek squad said something about my monitor plug ins I told them my computer recognizes the dual setup but won't work independently. He said you can keep tweak it but he has 3 monitors an although they will learn his only remembers about 70% of the time. I'm going to try hooking it up toy TV as a monitor. I just want to use it for security cameras. I do have a DVR I could use but I normally just use that when I'm ghost hunting. I'm actually I union millwright and part time ghost hunter so I'm not to well versed in computers or the talkology but I'm learning. Anyway my laptop w win8 works just fine. But... I truly appreciate I taking the time to respond an at least offer a solution thanks so much an I apologize for running my mouth on an on. Take care V.

  • MacPro1,1 Geforce 7300 - Dual Monitor won't work

    Hi there,
    I just bought a MacPro1,1 with 2xDual Xeon 2,66 GHz processors. It comes with the standard setup of HD, Memory and the Geforce 7300 GT graphic card. The Graphic card has two DVI-plugs (DVI-D & DVI-S). So far, so good.
    But when I attach two monitors to the DVI-plugs the second monitor gets no signal. If I then attach the second one with a VGA cable and a DVI-to-VGA switch it works (but with a bad quality/resolution).
    How can I connect both monitors to the 7300 GT using DVI? Is the card broken or do I have to get bigger graphic card?

    I'm running 2 DVI monitors off a 7300 GT in a Mac Pro, so it does work in theory.
    Some ideas:
    Have you tried switching cables?
    Have you tried one monitor at a time to each of the DVI ports?
    If one DVI port never works with DVI, it's probably a bad card.
    Also, I've found that VGA signals are not quite as good as DVI, but if you are really getting poor image quality with VGA, then there is a problem with the card, the monitor, or the cable.

  • My Viewsonic monitor won't work with the Imac using the Mini Port to DVI adapter.

    My Viewsonic monitor won't work with the Imac using the Mini Port to DVI adapter. I also tried the HDMI to DVI adapter ane the Mac-Mini with same result. The monitor does work on my older Macbook Pro that has the DVI connector. Is it a Software/Driver issue ?

    Should be extremely simple, please carefully read Connect multiple displays to your Mac. If you still have problems then it's probably a cable issue that would be resolved by replacing the adapter cable. You should be using this adapter. If you are using a third party adapter that might be your problem!

  • Thinkpad T420 with Dock 4338 Dual External Monitors won't work

    Hey Everyone,
          I recently purchased a T420 with Dock Model 4338 and am trying to connect two external monitors.  I want to have my desktop visible on my primary monitor with laptop closed and that desktop extended onto my second external monitors.  Both external monitors are Dell 19", one is being ran through the VGA port on the dock and the other is a VGA cord that I put a VGA to DVI-D adapter on to run off of one of the DVI Ports on the dock.  I can get my desktop to display on the main external monitor, and everything detects the other monitor fine, but the extended monitor remains black.  The screen is on, and recognized as the button light on the monitor is green not yellow and i can scroll my mouse over to that window and i lose the mouse so it's extending just not visible.  I have made sure that both monitors work by checking each individually in the VGA port and they are operational, but the DVI-D port doesn't seem to work on my second monitor.  
         I have done some pretty extensive searching and can't seem to get this to work.  At my job I have a T430 with the same dock and dual monitor setup that took no time and works great.  Does the T420 just not support this?
    All help is appreciated.
    Thank you all,

    DVI-D don't support passive dvi to VGA adapter. You are better off with a displayport to VGA adapter, as they are cheaper then a dvi-d to VGA converter.

  • Hyundai LCD monitor won't work with OS9

    New Hyundai LCD monitor -dual input. Works fine with Windows XP, & with OS 10 but when I boot into OS9 the screen goes black, & the screen's menu button won't work. Have started os9 in safe mode but cannot find how to change the display/resolution/refresh settings. Where do I look to change these settings? And what settings should I try?

  • External Monitor won't work

    I have a MBP 17" Late 2011 model with the Intel HD 3000 and AMD 6770M grpahics cards. I have read through many of these posts and found the exact same problem that I am having as well. I hook up a monitor through the VGA connection; Windows sees the monitor and even correctly idenifies the model; however no picture on the screen.  Also, when monitor is connected is shows the startup windows screen and even the Safe boot screen; but the second it gets into the desktop the screen goes away on the 2nd monitor. I have tried many of the solutions; updating boot camp drivers, updating AMD drivers, etc. and no joy.  When updating the AMD drivers, AMD's website detected that the hardware was the 6700 series and windows 64-bit; gave me the drivers to install and when installed the drivers their program ended up saying that the hardware was incompatible and not the right one.  Why is this so hard and can anyone tell me what to do, also is it possible to get windows to see the Intel HD 3000 card or is that just not possible.

    I have followed your advice and still no go with dual monitor through VGA.  However, here is an interesting note.  Using the ATI drivers from bootcamp 4.0 disk, the program detects the graphics card as a 6740 and not a 6770M.  However, AMD's own website detects it as what Apple stats in their specs, a 6770M and when it give the the drivers to install that, the program won't load it saying it is the incorrect hardware/software match up, but it does the SAME decting with the boot camp drivers and goes a head and installs the drivers for the 6740.  I am not sure what to do, so here's a run down again of what I have and what I need to do:
    MBP 17" 2.4 GHz Intel i7, 4GB RAM 1333
    Bootcamp 4.0
    Windows 7 Home Premium 64-bit edition
    Trying to use dual monitors through the VGA adapter, VGA adapter and cable work (works in safe mode, start up, and in OSX).  Once in Windows 7 desktop, 2nd monitor goes dark and won't respond.  I have gone into safe mode, uninstalled the display drivers, clean registry, reboot into safe mode, then install the bootcamp ATI graphics drivers (no go), rinse, repeat, tried using the drivers that AMD's website detects of the device (no go), rinse repeat went back to the bootcamp ATI drivers just so I can still use the main screen.Has anyone else figured out this problem.

  • Dual Monitors no longer working

    Hey there, I've been without net for a few weeks so I haven't done a full system upgrade in about a month. I normally have two monitors running just great using TwinView but I've recently picked up a new monitor that I'm using to replace one of my older monitors in my setup. Using the same xorg.conf (didn't think much, aside from naming the device, needed to be changed) so I plugged it in and all that fun stuf,f got it set up right, and I'm able to view the monitor that isn't showing up when starting X during boot and while starting up. What's strange is that I've had a different, crappy, monitor plugged in and started x and it worked fine and while X was still running I plugged in my current "to be desired" monitor and it worked! Though when I restart X I can't use it anymore. I'm not sure where to start with this one, I'm a bit of a noob so hopefully someone can lend a hand.

    - I've upgraded xorg (though a release hadn't happened) in an attempt to remedy ths
    Any help would be GREATLY appreciated

    I've never used twinview, but I would like to see this figured out.  My guess is that maybe the LCD isn't reporting to the comp correctly?  Maybe you should check dmesg for anything about either?  I know some have DSDT issues, and plugging in the old monitor before means it's probably erroring out on something small and fixable when your have the new monitor in.
    G'luck.

  • 2nd Monitor won't work

    I bought a Pavillion p6210f last week with Win7 loaded to replace my Dell/Vista.  I was using two monitors with a VGA port and DVI port on the old PC, so I tried plugging in the same on my new HP and the DVI would not fit.  In examining the pins I found that, althought the Manual said DVI, but the plug has the pin/bar arrangement of a DVI-D.   So, I bought a VGAto DVI-D adapter and everything plugged in snuggly.  All pins and bar appear a match.
    But, it won't work.  This is what is showing
    NVIDIA nForce Serial ATA Controller   HP RC Mirror Driver [Display adapter]
    NVIDIA GeForce 9100 [Display adapter]
    Acer P241W [Monitor] (24.0"vis, s/n LB4040014320, March 2008)the one working monitor....
    After hours with the 800 support and hours of reversing the two Acer monitors, the DVI-D port is simply dead.  Anything plugged in to the VGA works fine, anything and any combination plugged into the DVI-D and cable switching etc. the 2nd monitor  is not even recoginized.  The NVIDIA control panel doesn't recognize it. The amber power light just stays that way and nothing ever flashes on the 2nd screen.  That is, it is the same as not plugging in at all.
    I was less than pleased when 800 tech and supervisor suggested I take it to a repair center.  A week old?  I have put way too much setup and data transfer into the new HP to go back to the retailer for a replacement. 
    Techs didn't know, but could there be a DVI-X with the same pins that also fits

    Eldric, did you update to the latest video driver from nVidia?  It sounds to me like a driver problem.  Update and let us know if that solves your problem.

  • 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...

  • Preview Monitor won't Work

    I am using a Blackmagic card and have updated the codecs - I did a chat with Adobe and they remotely controlled my computer and still couldn't get it to work. The monitor works fine with Final Cut but won't work with Premier CC. Help.

    Hmmm ...  not sure where to even start, you didn't include enough details really ...
    For starters ... OS/version, which CC build you're running, some things like that? Around here this is a puzzle-out space with most of participants being "peers" in being users and not Adobe staff. Some staff post here on their own time, and are a great help. But so are many of the regular joe's and joeleen's who inhabit this space.
    Not thrilled that Adobe chat & help folks couldn't find the issue, but we'll see if someone around here will take on the challenge ...

  • 2nd monitor won't work correctly !!!

    Fresh install of xp on msi kt600 motherboard, and trying to get my G450 dual video card to work.  Every time I try to enable dual monitor the 2nd screen seens to have really bad resolution and bad refresh rates.  Can't figure out what is going on ....

    Thats sounds far more likely to be an issue with the AGP Card or Drivers over the MoBo TBH??
    If it's a fresh install have you ensured that you put the exact same Drivers back in etc lol??  I know that's a patronising question and I hate asking it, but it's so easily done these days with so much stuff we install too lol !!
    Otherwise, more info too to go on and then hope ya sorted soon !!

    I'm not sure Apple is going to write drivers for a Windows Operating System, so we may have to rely on the generic drivers.
    What model pavilion do you have?

  • Dual monitor suddenly stops working - flickering & vibrating

    Using a mid 2010 15" macbook pro with a LG Flatron W2261VP monitor and dual displaying these two worked perfectly for the past year with a HDMI cable into the thunderport. However suddenly it stopped displaying correctly, the MBP would detect the display correctly but the monitor would remain blacked out. The only resolution that functions is 1080i but it vibrates and flickers intermediately so unable to use without getting a major headache.
    Anyone have any suggestions on how to fix this issue without buying new hardware?
    Thanks in advance,

  • Monitor won't work via mini-dvi to dvi adapter

    It's a brand spanking new mac mini. I attached a 5 year old lcd monitor (always used before as VGA) using the mini-dvi to dvi adapter. I am using the monitor's dvi connector. The monitor resolution is 1280x1024.
    The monitor does not work when using the mini-dvi to dvi adapter. If I remove the mini-dvi adapter and use a mini displayport to dvi adapter, it works just fine. I can keep both adapters plugged in and plug the cable into one or the other. It always works instantly when attached to the minidisplay port and doesn't work if I switch to the mini-dvi port.
    I've tried the display with mini-dvi adapter on my macbook too. On the laptop, it acts like there are two screens attached, but there is no action on the external display.
    As a further test, I attached the mac mini to the TV via a mini-dvi to hdmi adapter. The mini-dvi port on the mini works fine, as does the port on the laptop. The monitor works fine via minidisplay, but not mini-dvi.
    Naturally, I concluded that the mini-dvi adapter was faulty. A second adapter came today, and nothing has changed. Could I have received two Apple mini-dvi adapters in a row with problems? Is there something about the monitor that doesn't like the mini-dvi port? It seems like it wouldn't like the minidisplay port either, but that one is fine.
