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.

Monitor stopped working - says No signal


Hi Paul,

This problem is often the result of a loose video cable connection on the computer or an incorrect video signal selection. Most monitors use a cable with "VGA" connector on the end that mates to the computer video port. Other modern computers make use of an HDMI (like the ones used to connect a TV to a BluRay Disk player) or DVI connector instead - either way if it is loose you will get the same "No Signal" message on screen. Make sure these connectors are making good contact with the port on the computer by seating them fully (or better yet - remove and reinsert). In the case of the VGA connector, most have two screws to hold them in the port - you should make sure both are threaded all the way in. You do not need to crank them down, finger-tight is more than enough.

Many newer - flat screen types in particular - do not have the video cable permanently attached. Instead, they use the same cord and connector arrangement found on the computer. It is possible that the connector has become loosened on the monitor end - especially if the monitor is moved / adjusted frequently. You should check the connections at the rear of the monitor just as you checked at the computer, too.

When satisfied that the connections at the computer and monitor are good, check the monitor again. If the message is still present, the monitor may be able to select between an analog input and a digital input via a menu item accessible from the monitor. Check your monitor manual for instructions to change inputs if unsure. If you are using the "standard VGA cable" (the one with the two screws) you should select the analog input. If you're using an HDMI cable, you should select the digital input. If you're using an DVI connector the input may be either analog or digital. When making a change, wait 5 to 10 seconds between toggling between the analog / digital selections to allow the monitor to sync the signal for proper display.

If you're still unable to display the desktop, it is possible that that someone has changed the BIOS options to select a different video card (if more than one is installed) or that the cable is defective.

I hope this helps and good luck!

Dvi port specification


The DVI [Digital Visual Interface] is a standard for high-speed, high-resolution digital displays.
Below is a 24 Pin DVI Female connector seen at the Computer. The connector diagram and pin-out table show a DVI-I Digital and Analog [RGB]; 29 pins [modified D style] connector. A DVI-D Digital only connector with 24 pins [modified D style] looks about the same with out the 4 analog 'C' pins.

The DVI interface is found on a number of devices including TVs, Computers, Monitors, and Video cards.
Digital Visual Interface [DVI] was developed by the Digital Display Working Group (DDWG).
Note that the Digital Display Working Group disbanded around 2006, so don't expect an up-grade for DVI.

Digital Video Broadcasting/Digital Audio-Visual Council (DVB/DAVIC),
developed by DAVIC [inactive] and DVB [dvb.org].
Adopted by European Telecommunication Standards Institute (ETSI) and
International Telecommunication Union (ITU)
DVI has a number of different types connectors:
DVI-D Digital only connector; 24 pins [modified D style];
DVI-A Analog only; [modified D style], I don't think this is part of the standard
DVI-I Digital and Analog [RGB]; 29 pins [modified D style]
DFP Digital Flat Panel, Digital only connector. Pinout is listed on the DFP page

Hdmi will not work only use of component cables will.


Hello

The HDMI[1] input on your TV receives digital audio

and uncompressed digital video and audio from an

HDMI device or uncompressed digital video from a

DVI[2] device.

This input is designed to accept HDCP[3] program

material in digital form from EIA/CEA-861/861B-

compliant[4] consumer electronic devices (such as a settop

box or DVD player with HDMI or DVI output).

The HDMI input is designed for best performance

with 1080i high-definition video signals, but will also
accept and display 480i, 480p, and 720p signals.

To connect an HDMI device, you will need:

• one HDMI cable (type A connector)

For proper operation, it is recommended that you use

a short HDMI cable. You should not encounter

difficulty if you use an HDMI cable shorter than 16.4

ft (5m).

HDMI cable transfers both video and audio.

Separate analog audio cables are not required (see

illustration below). Some CDVs (video CDs) may

not output digital audio signals. In that case, you

may hear sound by connecting analog audio cables.

However, if you connect analog audio cables with

this connection, the HDMI terminal on the TV will

not receive the HDMI digital audio signal and you
will hear analog audio only.

To ensure that the HDMI or DVI device is reset

properly, it is recommended that you follow

these procedures:

• When turning on your electronic components,

turn on the TV first, and then the HDMI or

DVI device.

• When turning off your electronic components,

turn off the HDMI or DVI device first, and
then the TV.

To connect a DVI device, you will need:

• one HDMI-to-DVI adapter cable

(HDMI type A connector)

For proper operation, the length of an HDMI-to-

DVI adapter cable should not exceed 9.8 ft (3m).

The recommended length is 6.6 ft (2m).
• one pair of standard analog audio cables
OK

Monitor wont come out of sleep mode


I'm guessing you are using a the VGA input of this monitor (the smaller "D" shaped connector with 15 pins) on the back. If not, and you are using the DVI input (larger white connector), then check your PC video output. I've seen this occur with HP monitors when they accidentally get set to "digital" input. Its easy to set that way (even by mistake), but not as easy to reset to analog (VGA). To do that, you'll need to find someone with a DVI output on their video card. Once you connect to a DVI source, the monitir will come on and stay on. You then need to go into the menues of the monitor, find the setting and change it back to "analog". After you do of course, you won't get an image on your monitor until you reconnect to an "analog" (VGA) source.

VGA connection works, DVI does not


Everything seems perfectly normal...

When you connect the computer to the monitor via an analog VGA cable, you get signal on the analog input.
When you connect them via a DVI cable, you feed the monitor's DIGITAL input, so the monitor doesn't get any signal on it's analog input, and informs you about it.
You have to select the digital input from the monitor's On Screen Menu, and then start the computer up - you should see the picture OK.
Also remember to set the display resolution on your computer to match the optimum (native) resolution of your monitor - this will give you optimum picture quality. In case of VA712B it will be 1280x1024.
Good luck and please come back with a testimonial if helped.

Monitor not working with converter


You have to make sure the DVI output of your computer supports analog video.

Check online for a DVI pinout. You will see the group of 4 or so pins to one side of the connector provide analog VGA. If your Video card (or cable) doesn't utilize those pins, then your monitor isn't going to be supplied the signal it needs.

Video Input Selection Problem


That is due to the fact that you can only connect 1 desktop to the HP LP2465 as most monitors.

For one the LP2465 does not have the picture in picture technology and for another the two ports you are connecting your Macs into are DVI (Digital Video Interface) connections. One is the Single DVI and the other is a Dual DVI.

It does not mean you can connect two Mac computers to the same display and both work. That is not practical because there is only one video input interaction possible with a computer and a monitor.

The DVI connections are determined by their ability to use either Analog and Digital signal transmissions through one connector.

So in order to effectively use your HP LP2465, you can only use 1 computer with the monitor because it is not designed to work with two computer graphics cards at once. Most LCDs have only one DVI or VGA connector to connect to a computer- your just happens to host two types of DVI connections is all..

That is the reason one computer is on with your display and the other is not displaying any video.

Take a look at this great explanation of the differences between Single DVI and Dual DVI connectors via this link:
Digital Video Interface (DVI)- Defined
