How do in put vga


1) http://www.newegg.com/Product/Product.aspx?Item=N82E16813121383

Click on the photo of the motherboard. Bottom row, third port from left.
Connect a VGA monitor to this blue port.

Example of a VGA cable, and VGA connector,

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

You can use a CRT type of monitor,

http://www.wisegeek.com/what-is-a-crt-monitor.htm

,or a flat LCD screen monitor with a VGA cable,

http://na.suzohapp.com/monitors/49260310.htm

If the flat LCD screen monitor has a DVI cable, and you are connecting to the VGA port on the back of your computer, you can use a DVI to VGA adapter,

A) http://www.directron.com/dvitovga.html

B) http://www.directron.com/dviadapter.html

Look at the monitor cable connection, on the flat LCD screen, and VGA connector on computer.
Compare the above connectors to get the correct adapter.

No? Not what your problem is? Then I will need someone who can state your problem in fluent English. My apologizes that English is the only language that I understand.

Can i connect two monitors to a nvidia geforce 315 card so as too use two monitors


hi,
yes the 315 desktop card does have multi monitor support. you may however need an adapter for one monitor as it only has one dvi ,one hdmi and one vga.
so you can hook up any 2 as a combination but they have different plug configurations to do this

hope this helps

Viewsonic vp912b lcd display will not work.no DVI


Yes you can but there should be an option in the monitor settings for DVI... Maybe if you go into safe mode and attempt adjusting settings for the ati for the dvi output, from what I hear that monitor is nice with the DVI option would be aa shame to lose that.

"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
