Question about ViewSonic VA712B 17" Flat Panel LCD Monitor

1 Answer

No digital signal but analog works fine

I've got both a mac and pc with digital connectors to test the connection, tried switching dvi cables, and fiddled with every setting, but for some reason can't get a digital signal to appear. Only analog. When there's nothing but a dvi connection then I get a "No Signal" Message on the screen. When both analog and digital are connected, the display switches to analog after I try selecting digital. The digital connection worked fine until about a week ago.

Re: No digital signal but analog works fine

Seems like this was already answered? But once you've checked against the owner's manual and ruled out the PC, I would suspect the signal / video board inside the monitor. May have gotten a surge or static, etc.

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.

How to switch from analog to digital mode

Any contemporary monitor is able to switch analog/digital mode automatically if connection from signal source to monitor is set up properly.

Connect digital output from your graphic card to DVI input of the monitor. Disconnect any other signal cables from monitor and switch on both devices (PC & monitor). Wait a while. Monitor checks its inputs and a activates digital DVI, because it is only one active input on it.

If none picture excluding error message of monitor is displayed, go through these steps:
1) Check whether your monitor is set for automatic input selection. If monitor buttons have no response try to use analog input to activate screen (any picture, desktop background...) and then get monitor menu access by pressing menu button.

2) Find out what connector type has your graphics card in PC. Possibilities are: DVI, HDMI, DisplayPort and some their options. See Wikipedia for connector look if you are not sure.
Remember that blue D-SUB (VGA) connectors are analogue and you cannot activate digital mode through analog VGA cable.

3) Use appropriate cable to connect monitor to PC.
Example: Your PC has HDMI output. Use HDMi-to-DVI cable. Your monitor input is DVI and common DVI-DVI cable is not suitable in case you have PC with the HDMI.
Note that DVI-to-DVI, DisplayPort-to-DVI etc. cables are available. You must buy right one.

Be aware that "Auto" button is inactive in digital mode of monitor.

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.

Saying no d,sub signal

Ok, Can you confirm that there is connection to the source PC?

If so if that connection is Blue usually means analog (and your Monitor was switched to Digital) Hit the 2 Button to switch back.

If the cable is white, it should be connected to DVI and should be connected to the Digital.

If there is, do we have another monitor to swap out to test from the pc?

As a whole this issue comes down to the PC is not sending a signal to the monitor (either do to a crash on the PC side, or a severed cable..

I have a Dell computer that runs Windows Vista and I want to hook it up to use my TV as a monitor to watch a webcast. Please advise.

The first step is to inspect both your laptop and TV and identify the connections, easily located on the back of either component. There are five basic types of jacks, or ports involved:
*Composite/phono plug (RCA)
*Video graphics array (VGA)
*Digital video interface (DVI)
*High-definition multimedia interface (HDMI)
*An RCA connector, sometimes called a phono connector, is used for analog audio and video components. Three round, colored sockets are standard — left audio is white, right audio is red, and composite video is yellow. These are standard jacks on older TV’s and laptops. A three-prong cable, readily available at any computer or electronics, is the easiest way to make an RCA laptop to TV connection.
*S-Video, or Super-Video, a more advanced analog video connector, uses a four-prong round plug, like those used in TV cable installations. Separate audio cables are the same as for the RCA connector, left audio/white, and right audio/red. S-Video is commonly found on older TV sets and some laptops.
With S-Video on both TV and laptop, connecting a laptop to a TV is a simple matter of a single S-Video cable. If your laptop has a great sound system, you won’t need audio cables, but for better quality you’ll also want audio cables.
RCA to S-Video cable, a special laptop to TV cable, is available when you have RCA jacks on one device and an S-Video port on the other.
*A VGA connector and cable are used to carry analog video signals plus display and graphics data. The VGA is a 15-pin connector commonly found on laptops and other devices. With this port you need a PC-to-TV Convertor to connect laptop to TV. You simply plug the VGA cable from the source into the convertor, and use an S-Video or RCA cable out to the TV. The converter is USB powered, so there’s no external power adapter to carry around, making this laptop to TV connection entirely portable.
*A DVI port is rectangular with 24 pins arranged in three horizontal rows of eight pins for digital video; separate RCA analog audio cables fit into white and red plugs. DVI ports are found on Macintosh laptops; sometimes they are smaller than normal DVI ports and require an adapter, which usually comes with the laptop.
*The HDMI port, one-half the size of the DVI port, is also rectangular with 19 pins. It provides digital audio in addition to digital video, despite it’s smaller size, for a complete TV to laptop connection. These ports are found on new HDTVs, and sometimes there are two or more. TVs with HDMI ports are the only ones that do not require additional audio cables.
TV’s with a single digital port labeled HDMI/DVI require only one cable when the source is another HDMI component. But when source is a DVI laptop, you need a DVI-to-HDMI cable for the video and a separate pair of RCA analog stereo cables.
NOTE: Whenever ports do not match, you can by adaptors and/or cables to make any connection.

No signal

You don't specify what kind of monitor, CRT, LCD, or even a TV attached to your system, you're using. It's likely the monitor is set to receive a certain kind of signal (either analog or digital) but it's receiving the other one instead. Before proceeding to the next steps, ensure the connections are solid and the the screws are set tightly and there's no movement.
Get your user's manual and learn how to navigate the monitor's menu in order to get to the setting where you choose Analog (for a VGA cable connection) or more commonly with LCD screens, Digital (DVI).
VGA and DVI connectors differ in shape and in the number and layout of their pins. If you're using a video card with a DVI connector (larger, more squarish D shape, with three separate sections of pins) then your monitor shoud be set to Digital. Else, your connector is VGA and thus your monitor should be set to Analog.
If both are in synch and you still do not get a signal, it's possible the video card has given out its ghost, since if you DO see the NO SIGNAL message displayed on your monitor, the monitor is Ok.
Good luck!

Cannot get sound using dvi cable

I need help setting up the DVI input.


There are two ways to do this.

First and simplest is to simply shutdown the pc, disconnect the analog from the back of your PC and connect the DVI cable to the PC and monitor. When you turn it back on the PC will detect and switch to the DVI.

Second, and better to compare. Connect both sets of cables and go into your display settings, then select advanced options. You should see a GeForce tab in the advanced menu. On that tab there is a multi monitor display setup. Set it to mirror to both screens and apply.

Once it's set switching inputs on the monitor SHOULD work. The problem that makes it a "should" is that both the monitor and the video card have the ablility to sense a connection. So, even with mirroring setup you may have to use the first method as you can't have both connected and operational at the same time.

Give these a try, if you're not sure how to get into the display settings, comment back here with your windows version and I will give you a step by step

Inoperative monitor

Here are a couple things to try.

1. try the input select button on the monitor (The minnus button) without pressing the OSD menu button 1st, see if it changes to analog.

When the DVI self-test screen is up, it is indicating monitor is in DVI mode.

2. If that doesn't work, try a DVI to analog converter on the DVI port on the monitor and connect the analog cable to the converter. See if you get any video that way.

3. If you can access the On-Screen Display (OSD Menu) perform a factory reset.
