What is vga/dvi cables

VGA and DVI is in the way the video signals travel. VGA connectors and cables carry analog signals while DVI can carry both analog and digital. DVI is newer and offers better, sharper display compared to VGA. You can easily tell them apart because VGA connectors (and ports) are blue while DVI connectors are white.

in this situation, there are two options. 1.The device connected to your TV via DVI cable is off. 2. DVI cable connected to the HP L1950 is burned.
if you try to connect a device to the HP L1950, it has two ways to connect:
Input Signal - Two connectors: one 15-pin mini D-sub analog VGA and one DVI-D. Try VGA them.

A blue display box continually pops up with Input Select D sub DVI. I am thinking it is something to do with the monitor. What is wrong?

This monitor has two types of video inputs, a 15 pin VGA D-sub connector and a DVI connector.
If the video card has a 15 pin D-Sub then connect the video cable to the 15 pin D-Sub connector on the monitor.
If the video connectors are DVI then connect the video card and monitor with a DVI video cable.
You will also need to configure the monitor for either the D-Sub or DVI video input.

I would like to remove the OSD warning pop out "Attention" from my monitor. What I need to do to achieve this?

If you are getting a message that says something like "Check cables" " no signal detected" or something like that, it is likely that your monitor is operating correctly. I would suggest checking your cables, make sure that the computer is turned on, and if that doesn't help, check if your monitor has VGA, DVI, or HDMI inputs. I am thinking that your monitor may be trying to display from the wrong source. This is what a VGA (analog) cable looks like. VGA cables are typically blue.
Another common connection that is used is a digital HDMI (left) or DVI (right) connection. DVI cables often have white end connectors. How your PC connects to your monitor will determine the source mode you want to use on your monitor. (Obviously this is the cable view but the connection on the monitor itself will look similar.)
If none of these tips helps, I would suggest hooking the same monitor up to a different PC or laptop, and trying once again to get a the display working. Again, make sure that the connection matches the source setting on your monitor. If it works on another PC, then your computer may have a video problem.
Otherwise, if it still does not work your monitor have a problem displaying via that connection. If possible I would suggest switching to a different type of cable and re-try the above steps.

DVI ==> Digital Video Input
If your monitor has both DVI and VGA inputs,
and your PC's video-card has both DVI and VGA outputs,
then buy a DVI-to-DVI cable, and use it, for a better picture.
If your monitor has both DVI and VGA inputs,
and your PC's video-card only has VGA output,
then use a VGA-to-VGA cable.
Or, purchase a video-card with DVI output,
to replace the video-card with VGA output,
and then use a DVI-to-DVI cable.

Monitor only works with DVI/VGA adaptor.

if your monitor came with a disk try installing the drivers again you might still have the drivers for the previous monitor you had with your system if not try going to the manufacturers website and getting the drivers and install them

"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

DVI connection

Did you try your monitor with another output (VGA)? If not, try it.
So, you have to check and make sure where the problem is (display card, monitor, or cable). Try with another cable or monitor. This way you will know where the problem is. If you don't have another monitor, try the monitor you have with build in VGA output on motherboard by taking the display card out.
Thank you,

DVI input on monitor not working

Contacted viewsonic about this issue- they suggested- have both dvi and vga hooked up to same machine. start with poweroff on both. power on monitor, then power on computer. when you see display coming from the vga, power off pc, then disconnect vga cable, turn off power to monitor, disconnect power cord from monitor for 5 + seconds, reconnect power cord, power on monitor, then power on pc.
If this doesn't work to get the dvi working, (as happened to us) we returned our monitor for a replacement, since it was still under warranty.
