additional monitor to use as extended desktop

maggielou43
Hi, PC HP Compaq running win 7. The PC does not have a DVI Port or HDMI only VGA. It has intergrated intel G41 chip graphics. I used a vga splitter cable to run 2 monitors but they just mirrored. I could not even set separate resolutions. Windows did not detect the 2nd monitor .I downloaded the 2nd monitor's drivers from the original hp disk but still no joy.
can I do anymore to enable running the 2nd monitor as an extended desktop, or is this not possible because of the graphics and/or no DVI or because the main 22" monitor is actually a television. Running it as just a mirror of the main monitor is pretty useless. Thanks

      A VGA splitter is just that; it splits (mirrors) the signal to another monitor. You to buy a graphics card that supports dual monitors (has two connections) to enable the extended desktop. Once you install the new graphics card, the on-board video connection will be disabled.

      you can also use a USB to VGA cable/device. I have used that solution in the past. Not as good as dual port video card, but a lot easier to install.

      If you're not looking to do anything graphically intensive, you might be able to find an old PCI VGA card (make sure it's a later model with 1-4MB RAM) somewhere for a pittance, if someone isn't just throwing them away. This could be used to plug your second monitor into. If your computer has an AGP slot, installing a video card will override those built-in graphics. You SHOULD be able to get away with it if it has a PCIe slot, although most PCIe cards will have their own dual monitor support anyway...

      That sounds like a good idea in theory. I've tried it with Windows 7 before and it was painful though. Drivers are a major issue. I used a really standard card that had it's driver built-in to XP. I either couldn't find a Vista/Win7 driver, or it wouldn't work (can't remember which one... this was a year or two ago). I spent an hour or more trying to get it going without success. I'd say the OP has less experience in this area than me. Another problem is that Aero uses the video card for rendering in Win7 - an old PCI card isn't likely to be up to this.

      In my opinion it just isn't worth going down this track. A new dual-head video card will cost about $30. It'll be a plug and go solution, and will come with a driver CD in the box that the OP can just plug in and hit Go.

      Hi Thanks, everyone, for all your help and support. Found a dual graphics card on Ebay with the dual cables for £13 gbp. I havent ordered yet as i want to get back to you with the details and perhaps you can advise, before I pay the man. It also needs to be compatible with Linux Ubuntu so have to check that out as well. Thanks again

      Found this:
      Full Height NVS290 PCI-E x16 Quadro 256MB Video Graphics Card +Dual VGA Cable HP
      Dont really understand it: there appears to be a split cable to attach a vga cable to each monitor but still only one connection going into the pc tower????

      The seller has been very nice and has assured me that it is the correct item for the job.
      What do you think please thanks

      That'll do the job. The one connector on the video card is a proprietary one that HP make. You can't plug a monitor directly into it - it splits out into a pair of VGA connectors. That cable looks very much like this - http://compeve.com/images/LFH_59_VGA.jpg

      He is correct that this will do the job. Your computer will recognise the two different monitors you plug in, and will let you extend on to the second screen. Provided you're happy using VGA for both monitors that card is a suitable choice.

      Sorry to add another thing that is worrying me. The nvidia graphic card that i purchased appears to get quite hot. it did not come with a fan nor did the seller suggest that a fan would be necessary.
      I have never had an external graphic card before, only on board graphics so i dont know quite what to expect. Please advise. Thanks

      Hi reference my previous posts. new graphics card worked fine on windows, but on Ubuntu 13.04 it detects only the HP x19" monitor. The TV22" screen boots to grub ok then into Ubuntu. At this point it goes blue with a no "signal text" box and the HP screen takes over.
      I have asked the question on the Ubuntu forums and been told that it is a driver problem. Checked and Ubuntu is using Nouveau drivers.
      I find this difficult to understand. Ubuntu OS, graphics, & monitor all work perfectly on the HP screen so why would different drivers be required just for an additional monitor. Prior to installing the graphic card the 22" monitor worked perfectly but ubuntu does not detect it now.

      Anyway I tried another 8 Linux distros and all automatically detected both screens including Ubuntu 12.04LTS Ubuntu 12.10, Lububtu, Maggiea, Mint, Full Monty, etc.

      Tried Ubuntu 13.04 newly bunt iso cant detect 22"TV monitor
      Tried Ubuntu 13.04 64bit & 32bit cant detect 22" TV monitor
      Tried xrandr -q output

      maggie@margaret-VS273AA-ABU-CQ5226UK:~$ xrandr -q
      Screen 0: minimum 320 x 200, current 1366 x 768, maximum 8192 x 8192
      DVI-I-1 disconnected (normal left inverted right x axis y axis)
      DVI-I-2 connected 1366x768 0 0 (normal left inverted right x axis y axis) 410mm x 230mm
      1366x768 59.8*
      1280x1024 60.0
      1280x960 60.0
      1024x768 60.0
      800x600 60.3
      640x480 60.0
      720x400 70.1
      maggie@margaret-VS273AA-ABU-CQ5226UK:~$

      Obviously the DVI-I-1 is disconnected but why does it work on all the other distros.
      Hoping that there is some Linux people in TR that can help please. Thanks
