http://support.gateway.com/s/PC/R/1009371/1009371rv.shtmlYou cannot run dual monitors off of the motherboard. BIOS will assign only one IRQ.(Interrupt ReQuest )That 9-pin connector (C) is a Serial port. This = No
http://support.gateway.com/s/PC/R/1009371/1009371rvr2.shtmlhttp://en.wikipedia.org/wiki/Serial_PortYou need a graphics card.Don't be thinking of one monitor to motherboard, and one monitor to graphics card.One IRQ, and it's assigned to either the -> motherboard graphics (Integrated), or a -> dedicated graphics card.Two monitors to graphics card.I am using a lesser model;ATI Radeon 9250, and it's a PCI graphics card.Goes in a white PCI slot.
http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=5247980&CatId=1603My PCI-Express graphics card gave up the ghost. (8 years old. It's cool)I replaced it with the Radeon 9250 so could run dual monitors again.Does fine for on here, Adobe Photoshop 7, YouTube, etc. Not a gamer.(I have a Powercolor HD5450 PCI-Express graphics card I'm going to use, when I get off my duff, lol! Requires a 400 Watt power supply)I use an HP 2009m 20-inch widescreen, as my Primary monitor, (Left side of computer desk), and a Philips 26-inch HDTV as my Secondary monitor. (Right side of desk)Do you have two VGA (CRT) type monitors, or is one a flat LCD screen digital monitor?Some flat LCD screen monitors have dual hookups.One for a VGA cable, and one for a DVI cable,
http://en.wikipedia.org/wiki/Digital_Visual_InterfaceIf you have two VGA monitors that are the CRT type, (Looks like a small TV), and your graphics card has 1 VGA port, and 1 DVI port, they make a VGA to DVI adapter. Just make sure you get the correct one.VGA port on graphics card is Female.DVI cable connector is Male.This is the usual standard.This is the type of VGA to DVI adapter that is required,
http://www.directron.com/dviadapter.htmlALWAYS, install the software off of the Installation disk that comes with the graphics card -> FIRSTInstall the drivers, and the user control panel.(Driver: Small piece of software that allows the Operating System to communicate with a device.The graphics card is the device, do not know what version of Windows you are using.User control panel = ATI - Catalyst Control Panel. Nvidia - Nvidia Control Panel )Do Not worry that you will loose graphics, after installing the graphics card software. Windows will Not use the software until THAT graphics card is installed.Then after finished close all windows, go back to your desktop screen, and turn the computer off.Unplug from power, FOLLOW Anti-Static Precautions, and physically install graphics card.(Need to know about Anti-Static Precautions please post back in a Comment)Set your main, or Primary monitor on the left side, Secondary monitor on the right; of your computer desk.Turn the monitors on. If a CRT type allow them to warm up.Turn the computer on. Once Windows has loaded your desktop screen will be on the Primary monitor.1) Right-click on an empty area of your desktop screen2) Left-click on Properties3) Left-click on the Settings tabThe blue No.1 monitor icon is the Primary monitorThe blue No.2 monitor icon is the Secondary monitor.4) Left-click on the Secondary monitor icon.5) Left-click in the empty square box to the left of -Extend my Windows desktop onto this monitor6) Left-click on Apply at the bottom right7) Left-click on OK at the bottom left.Your desktop screen will now be on both monitors.(Advisory comes up asking if you wish to keep settings? Yes)Open your internet browser.Move your mouse cursor to the Right side of the blue frame/border.WHEN your mouse cursor turns into a Double-Headed Arrow, hold the Left mouse button down.It is a little tricky to keep the mouse cursor as a Double-Headed Arrow. Must be that, and then hold the left mouse button down.Holding the left mouse button down move your mouse to the Right, and drag the blue border of the internet browser to the Right.Keep dragging until it is all the way to the right side, of the Secondary monitor.Now you have your internet browser on both monitors.I run the internet browser on my Secondary monitor, (26-inch HDTV), and use the Primary monitor to look at computer functions, motherboard manuals, etc.Or I move the internet browser to the Primary monitor, play music videos from YouTube, and use the Secondary monitor for Photoshop.The world is your oyster.So there you have it. You need a graphics card, and it has to have dual monitor inputs. (Ports)Splitter cable thing? I wouldn't bother.IRQ -
http://en.wikipedia.org/wiki/Interrupt_RequestBuying a graphics card:Depends on what you want to do with it for one. You can see the simple stuff I do, doesn't require much graphics power. (More than Integrated Graphics, though, and can't use dual monitors on Integrated Graphics)The next concerns are what type of graphics expansion slot/s do you have, and how much Wattage (Power) the Power Supply has.You have a 300 Watt power supply, unless it has been replaced,
http://support.gateway.com/s/PC/R/1009371/1009371cl4.shtml(Scroll down; Power Supplies)Your motherboard has 2 white PCI slots. If one is available it can be used for a graphics card -> Not recommendedYour motherboard has one Black PCI-Express x16 expansion slot, that is used for a graphics card, also.It is right above No.1 white PCI slot.Highly recommended.(Gently Pull UP on the PCI-Express x16 slot -> LockIt looks as though you press down on it, when installing, or removing a graphics card )
http://support.gateway.com/s/MOTHERBD/INTEL/4006158R/4006158Rnv.shtmlSo when looking for a graphics card, look for PCI-Express graphics card, and system requirements / minimum power requirement; states 300 Watt power supply, or greater.For additional questions please post in a Comment.I know that is a lot to take in all at once. I can clarify anything you need clarified.Regards,joecoolvette
