Question about Acer AL1916W 19" LCD Monitor

1 Answer

Building new computer - nothing on the monitor.

I'm building my own pc from scratch. The motherboard had no integrated vga so I bought my own graphics card but no signal is coming out. It's a pci express 2 card and I have changed it's port
but still no signal.It's connected to the power so I dont think that's the problem. I thought it would bring out a low resolution screen without the drivers installed but is that the case?

No display but the computer turns on.


could be an issue with the graphics controller or with the monitor. first, verify if the monitor is actually working. try it on another computer or video source. if it works, make sure that you have a working video cable and check to make sure the video input source (dvi, vga, rgb, hdmi.. etc) selected on your monitor is the correct one that you are using. if you have ruled out the monitor, video source and cables, you can then test if another monitor will work with the computer. if same thing happens, meaning nothing on display even the manufacturer or BIOS screen does not show up when you turn on the computer, it is most likely the video controller. you may either get the motherboard replaced or install an add-in video card if the integrated video controller only has one video connector.

Bought new visionquest 19" monitor,


Nope it isn't defective. You don't mention from your question if you bought a LCD type or the CRT type of monitor. But I think you bought a LCD monitor right? My question here is where do you connect it? From the graphic card or in the onboard vga of your motherboard? How old is your graphic card/onboard vga? That is always the problem of an old graphic card because it can't release more pixels that's why it says out of range. Connect your old monitor it will work because it can support your graphic card/onboard vga. Buy a new graphic card with a specification that will suit to your motherboard and to your new monitor before it become a money waste

Does this motherboard have integrated video? Or do I need to buy graphics card?


Well if your computer is new generation computer than it has integrated video and you don't need to buy graphics card to view normal display.Now a Days all the new motherboard has integrated 128mb to 256mb graphic chipset in build , but if you want to play high resolution games and graphic works .


And if your computer belongs to old age,say 8-10 years old than you need to put a PCI VGA card to get normal display.

All the best.

Do u have a graphics card in the pc? If you have then disconnect the video cable from that and connect the video cable with the default vga port of the motherboard and check. if there is no graphics card then the integrated graphics card of the motherboard is damaged. that means motherboard is needed to be replaced.

Need to connect 3 monitors. Want to use either a Nvidia 290 or ATI Radeon 9250 plus the VGA port. Installing the dual-video card disables the VGA port, cannot get it back. Help!!!


Use your AGP dual-video card for two and using a PCI VGA card for the third. It is best if the same manufacturer video driver is used for both cards, as two different ones could be problematic.

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.

The integrated graphics may have bit the dust.. but I'd suspect a poor connection at the jack first. Try disconnecting the cable from the PC (and the monitor if not molded in) and reseat the plug(s) into the jack(s). Give it a wiggle and see if you can detect the red channel coming on. Check the VGA cable for signs of damage. If unable to get the red, you'll need to isolate the trouble to either a faulty graphics port or monitor. You can do that by swapping the monitor with a known good one OR installing a VGA card in an open slot of the MB. A third possible swap would be for the VGA cable if it can be separated from the monitor.

You may have to change a setting in the BIOS to tell the computer to use the PCI or AGP video if you go the expansion card route tho. Swapping the monitor shouldn't be a problem if you change the resolution in the OS to match the new monitor (or simply set to VGA) so that you don't over drive the replacement monitor.

Either of these two methods will provide you with a definitive answer as to the health of the monitor or graphics adapter. Just remember to change ONE thing at a time - don't make two changes at the same time as you won't know which is the faulty component.

I hope this helps!

Your new Foxconn motherboard Primary Graphics Adapter settings in set to onboard vga that is why there is no display in your monitor. Do not install yet your agp video card. Use first the onboard vga of the motherboard.
Power up your computer and go to the BIOS settings. Locate in bios about the Primary Graphics Adapter settings and then select AGP. Save changes and the exit. Turn off your computer and now install the agp video card.

Disconnect all PCI Cards and unplug power to all Drives then reboot your computer using the motherboard VGA port to see if the monitor will POST. If you still have a blank screen you most likely have a bad motherboard.

If you cant get into the setup menu then I would think the monitor is defective,you did not state if you hooked up the monitor to a computer that has a vga port that works.
