Hi curtdog46,
Many things can cause this but my suspicion would be RAM.
Try shutting down the PC, turn it off at the back on the power supply and remove your RAM.
(Leaving the PC plugged in, means you can touch the chassis with both hands and earth any static you may have in your body)
Use a small vacuum cleaner or brush to clean the RAM and connectors,
refit your memory and try it.
NOTE: You should not have to push the little locks into the ends of the memory. If you put them back in carefully and press them in correctly, the locks will go in by themselves as you push the memory into place. If you can, support the motherboard from underneath to prevent cracking it.

How to add second monitor on ECS RS482-M


Doesn't work that way Max.

You can use EITHER the OnBoard Graphics,
OR;
the Add-On Card graphics. (Graphics card)

BIOS will NOT support both at the same time.

If you wish to use dual monitors, get an AGP card that has more than one graphics port on it.

For example, although I'm using a graphics card based on the PCI Express technology, and not AGP technology; my card has a VGA port, DVI port, and HDMI port.

1) VGA Connector; http://en.wikipedia.org/wiki/VGA_Connector

http://en.wikipedia.org/wiki/File:Male_VGA_connector.jpg


2) DVI; http://en.wikipedia.org/wiki/Digital_Visual_Interface

http://en.wikipedia.org/wiki/File:Dvi-cable.jpg

http://en.wikipedia.org/wiki/Digital_Visual_Interface#Connector

3) HDMI; http://en.wikipedia.org/wiki/HDMI

I use the VGA port, and the DVI port.

RCA EN-V L26HD31, (26 inch HDTV) to the VGA port.
HP 2009M 20 inch Widescreen monitor to the DVI port.

Had to install drivers for HP 2009M.

Let's say I had two DVI ports on the graphics card.
(ATI Radeon HD5450 is the graphics card I have)

But I have a monitor with a VGA cable, and a monitor with a DVI cable.
I would (And have) use a VGA to DVI Adapter.
One example,

http://www.directron.com/dvi.html

Note that the DVI is Male, and the VGA is Female.
The graphics card DVI connector is Female.
The VGA Cable connector is Male.

So.............what is the manufacturer name, and model number of the graphics card; plus what type of monitors are you trying to use?
That is, what type of monitor cables do they have?

Know this;
My HDTV I'm using as a monitor is Digital. However I'm using a VGA cable on it. Best quality would be achieved if I got off my lazy rear, and attached a DVI Cable to it. It uses both.

VGA is Analog. A computer however puts out a digital video signal.
The computer has to convert the digital video signal to an Analog one. This slows the video signal down, and the quality is not as good.

Best to use a digital monitor. (Or a digital monitor WITH a digital cable. DVI Cable. Such as I need to do)

You are also using a PCI Express graphics card, NOT an AGP graphics card.

I'm wrong? OK.

In the meantime turn the computer off, unplug from power, and yank that AGP card out of the slot you put it in.

Tell me what expansion slot on the motherboard you put it in.

The Orange expansion slot on the motherboard, is a PCI-Express x16 slot. Uses a PCI Express graphics card -> ONLY

The white expansions slots are PCI.
Can use a PCI graphics card. CANNOT use an AGP graphics card.

Post back in a Comment.

You need to connect both monitors to a computer. Monitors do not daisy-chain (in general). The exception are some SCART-enabled monitors.

What is your source (desktop)? What is the make/model of your new monitor? Please add a comment with the video outputs/inputs for your source and second monitor.

Many newer desktops have two or three outputs. (Some video cards have display port outputs which with active adapters can support 2 monitors each.)

If your computer has two or more outputs and your new monitor has an input compatible with the extra output, get the appropriate DVI, DVI-HDMI or HDMI cable for your new monitor. See the next section if both monitors have VGA input.

If you have a desktop with only one video output, you may be able add a video card to support two monitors. (Depending on your computer, you may need to upgrade the power supply to support a video card.) Then get the appropriate adapter or cables to add the second monitor. (Note: if both of your monitors have only VGA inputs, check the specs for video cards carefully. Not all modern cards support analog outputs on their DVI, HDMI or Display Port connections. These digital outputs would require a digital to analog converter to give the VGA out.) However, if one of your monitors will accept DVI digital signals and the other VGA, add a card with one of each of these connections and a DVI cable to match. (This is an if needed extra; many monitors still ship with only a VGA cable.)

Then turn off your computer, open it and add the video card. Install the drivers with only one monitor attached. Then power down the computer and connect the second monitor. Turn on both monitors before turning on the computer again. Most of the time, the second monitor should be recognized (by Windows) and the appropriate refresh rate and resolution chosen. If not, you may need to enter the Display settings to set the monitor up.

I have seen some computers/video cards where only one output is initially enabled. You may have to go into the device settings to enable it. (Laptops often need their external video ports enabled in the BIOS.) Bad video ports/cards/cables do happen so RMA if needed.

The USB video adapter, http://www.newegg.com/Product/Product.aspx?Item=N82E16812225007 , can be added to a desktop to give a second VGA output but it isn't the best solution. USB bandwidth limits are significantly lower than those for a PCIe x16 slot or an old AGP slot.

I hope this helps. Please add more information about your system if you want more assistance with this problem.

(who has done dual monitors with older and newer computers. My old Pentium 4 with a Radeon x1350 video card was fine for driving a VGA monitor and an HDMI monitor (using a DVI to HDMI cable). My second generation i5 and P8Z68 motherboard system is also fine using the on-CPU video graphics for those same monitors. A video card would improve gaming but isn't required.)

Link ASUS laptop to Sharp Aquos LCD TV


No, a DVI to VGA adapter will not work. (The TV is looking for the digital signal from a set top box. This is different from the analog signal on the VGA cable.) You need a converter. Your best bet would be a VGA to component video converter. (I am assuming that the Sharp TV has a component video input.) This page has some examples: http://www.ramelectronics.net/audio-video/video-converters/vga-rgb-hv-to-component-video/c10000-c11200-c11215.html?sorter=productname-en-asc . Note a VGA to component video cable will not work. The VGA to component cables are for projectors that read the RGB signal. The component video signal is YPbPr.

Connect the VGA cable to the converter and the component video cable to the TV and the converter with the computer and TV off. Turn on the TV first and set it to the component video input and then turn on the computer. Then (assuming the VGA port is enabled - adjust in the BIOS if needed) set the computer's video output to the VGA port. (On my Windows 7 laptop, this can be done by right-clicking on the desktop. Choose Graphics Properties and set the display to the external monitor or both. Click Apply and then confirm the change (on the external monitor if using the single monitor). (VGA to Composite video converters also exist if you do not have an available component video input on your TV.)

If your computer is fairly new, you may have an HDMI port. Your TV may be able to read the signal with a DVI to HDMI cable. (It depends on the TV. Not all of them will read the computer's signal on the DVI port. Check the documentation for your model. TVs without a VGA port are less likely to support this feature.)

I hope this helps.

No signal to the monitor( no problem on DVI cable or monitor) may be the VGA card failed


I agree. However to fully determine, try a known-good monitor with known-good DVI cable. If so, the bad news is you likely will need either a third-party video card or a new systemboard.

1) No. The switch color should have been Green

2) No Signal on the monitor, indicates the monitor is not receiving a Video Signal from the computer.

A) Could be due to a faulty monitor cable.
Monitor cable is used on a working computer for a test,
Or,
working computer's monitor cable is used on the Advent for a test.

B) Could be due to the graphics 'engine' on the motherboard, or on the graphics card is bad.

[Graphics 'engine'.
GPU
Graphics Processing Unit.

http://en.wikipedia.org/wiki/GPU ]

If the computer is using Integrated Graphics, the GPU is on the motherboard.

(Integrated Graphics is also referred to as OnBoard Graphics. Meaning On the motherBoard)

You will know if it's Integrated Graphics, because the monitor cable will be plugged into the VGA connector, on the motherboard

http://en.wikipedia.org/wiki/VGA_connector

Since you indicate an adapter was included, to adapt to a different port (Connector), it could be a VGA to DVI adapter, or a DVI to VGA adapter.

Your monitor may just have a VGA connector on the monitor cable.
Hence you would use a female VGA to Male DVI adapter.

Your monitor may be an LCD flat screen monitor, and has a DVI connector on the monitor cable.
Hence you would use a female DVI to Male VGA adapter.

DVI
Digital Visual Interface

http://en.wikipedia.org/wiki/Digital_Visual_Interface

VGA monitors are Analog.
LCD monitors are Digital.

A computer puts out a digital signal.

If a VGA monitor is used, the computer has to alter the Digital signal to an Analog one.
This slows down the video signal.

If your monitor (In any case. Not just this one), is an LCD flat screen monitor, it is best to use a DVI monitor cable, and plug into a DVI port on the computer, if available.

If your monitor is a VGA (CRT. Cathode Ray Tube), monitor, and you have a DVI connection on your computer, using the adapter will do you no good.

The adapter just uses the contact pins for VGA, that are present in that DVI adapter, and hence the DVI connection on the computer.

You're still just getting an Analog VGA signal.

Example of a female VGA to male DVI adapter,

http://www.directron.com/dvi.html

If the Integrated Graphics are suspected to be bad, a graphics card is used in the appropriate expansion slot, for a test.

If the graphics work then, the graphics card is left in service.

After I test the monitor cable my next procedure is to suspect the Power On switch, or the Power Supply, and go to the graphics next.

The reasoning is that Power Supply failure, is the number one cause of computer failure.
The next is the Power On switch, then Electrolytic Capacitors used on the motherboard.

(Specifically, any Electrolytic Capacitors used in the motherboard Voltage Regulator Circuit)

If the Power On switch is bypassed, the diagnosis will reveal if the problem is the switch, or Power Supply.

Bypass the Power On switch, and the Power Supply comes on?
Problem is the Power On switch.

[One Power On switch I have found to fit a lot of computers. The Power On switch goes into the plastic Power On button,

http://www.directron.com/atxswitch.html ]

Bypass the Power On switch, and the Power Supply does Not come on?
The problem is the Power Supply.

The Power On switch is bypassed using a jumper wire, from the green Soft Power On wire, to ANY black Ground wire. The contact made is a brief momentary one.

The jumper wire is used at the back, of the 20, or 24-pin ATX main power cable connector.

Did you give the correct model of the Acer monitor you have?

When I looked up the X223W monitor, I see a monitor with a DVI-D port and VGA port. Only the VGA cable is usually included in the box. If your computer has a VGA port (most older computers that came with only the video chip on the motherboard), you can either use the VGA cable or get a VGA to DVI adapter and use a DVI-D cable (purchase separately). Alternatively, check the specs of your power supply and available card slots and buy a new video card with a DVI port. If you have only a DVI port on your computer, get the DVI cable (the VGA to DVI adapter would work but isn't a good option).

If I read the specs correctly, this monitor doesn't have speakers. You should plug your speakers into the audio out of your computer. If you use the on-board audio you will see at least two jacks (microphone/line in) and audio out (speakers). Many audio cards and some motherboards come with additional jacks for surround sound so check your system information. Audio extension cables are a cheap solution if the speaker cables are too short to reach to your computer.

I hope this helps.

"No signal detected" when LCD connected with DVI-D Cable


Thank you for providing your configuration details.
You have failed to specify wheather or not your LCD Display is under Warrenty.

Perhaps these simple trouble shooting procedures will get the job done.

1. use the DVI to VGA adaptor that came with your card

Plug in a regular CRT monitor to the Primary Display Output Port using the DVI to VGA adaptor
( either port can be designated as the primary by you )
I like to use the Port nearest to the motherboard as the Primary

2. plug in the your LCD monitor on Secondary Display port using your DVI cable

At this point you should be able to see your desktop on the Primary CRT Display

3. Go to the display properties and use the Nvidia Dual Display Setup Wizard

set both desktops to CLONED at a resolution of 1024x768 and set the refresh to 60Hz
which is default for most LCD displays , some have higher refresh rates , consult your user manuel

If the display resolution and refresh are set incorrectly for your CRT or LCD you will see
Signal Out of Range ( if the display has the ability to display that error message )

At this stage both displays should be showing a Windows Desktop

If you now see your desktop on both displays , you can now put the LCD on the Primary Port



No Signal Detected ( this means the display device is not receiving a signal )

If your LCD display is still displaying the error message
"No Signal Detected" after performing the trouble shooting proceedures
You may need to read the user manuel about how to enable DVI signal input.

If you are certan you have done everything correctly but still see only "No Signal Detected"

Your LCD Display may need replacement

My main computer has turned the monitor totaly purple when i just turn it on. i have tryed other monitors but they just have the same affect


Two possiblities

1. Bad cable (VGA and DVI cables go bad all the time)
2. Video card has bit the dust - and you would need a new video card - if the video is direct on the motherboard, you can buy a seperate video card - otherwise you would have to replace your whole motherboard.

Try using/buying a different monitor vga/dvi cable first though.
