Hi, Normally your connection should work straight out. Pls verify that your dvi output is enabled/activated by checking your display properties. In a Windows based OS machine, right click on any clear area of your desktop, click on Properties. Click on the settings tab, Advanced button. Check on the different abs such as Monitor, display and others. There should be an indicator for dual view or enabling/activating your secondary display unit (which is your projector). Hope this be of some idea/help. Post back how things turn up or should you need further information. It may also be of help if you can provide info on your PC. Good luck and kind regards.

How to Connect Laptop to Projector

How to display computer image on TV or projector
How to display a computer image on a TV or projector All modern televisions and projectors have one or more ports which allow them to receive and display an image generated by a computer. Both desktop and laptop computers are capable of connecting to a TV or projector, provided that they have the appropriate cables. The following sections contain instructions for using your TV or projector as a computer monitor. For best results, we recommend reading them in order.
Identifying available connections
Connecting computer and projector or TV
Display using Desktop
Display using Laptop
I don't see an image on my TV screen

Identifying available connections The first step in connecting your computer to a TV or projector is finding an identical port on both machines. Once the matching port has been identified (one that is the same on both your input device and output device), you need the appropriate cable to connect them. This section contains a picture of the back of an Epson projector and its available connection ports; as well as descriptions of each.

HDMI
The HDMI connection is very popular among display electronics. In fact, nearly all modern televisions and projectors feature HDMI ports. Most laptop computers support HDMI and it is becoming more prevalent on both desktop as well; even without a high-end video card. HDMI is quickly becoming the standard for all electronic equipment for its high quality signal and ability to carry both audio and video signals. The image to the right is that of an HDMI cable.


find-connect-projector-option-vga-hdmi-zonwsocbr3qazne24mugrpvs-1-1.jpg VGA
The VGA connection is the most common among both desktop and laptop computers, is found on most projectors, and some TVs. The VGA cable has a 15-pin connector on each end that plugs into a VGA port on each device. Due to the fact that most televisions do not support VGA, we recommend using HDMI for their wider range of compatibility.


find-connect-projector-option-vga-hdmi-zonwsocbr3qazne24mugrpvs-1-2.jpg Tip:VGA cabling is universal for devices that support it. For example, the if your desktop monitor that uses a VGA cable it, that same cable can be used by a laptop to connect it to a projector.
Note: If you are using an Apple desktop or laptop you need a VGA adapter to connect a VGA cable to the computer.

DVI
The DVI connection is newer than VGA and it offers a sharper image. Although the DVI port is not shown on the Epson model above, it is still somewhat common for projectors, not so much for televisions. It is mostly found among desktop computers for monitors, but some laptops have DVI connections as well (Apple laptops are more commonly known to support DVI than any other brand of laptop). Since finding DVI on a TV or projector is more difficult, we again recommend using HDMI cables.
Tip: There are special cables that convert from DVI to VGA or DVI to HDMI and vice versa.


find-connect-projector-option-vga-hdmi-zonwsocbr3qazne24mugrpvs-1-3.jpg
Composite Video
The composite video connection is quite common on a TV or projector, but it is nearly nonexistent on modern computers. This connection is the yellow female cable on what is normally a three bundle of red, white, and yellow. The only time you should see this setup is on older video cards for desktop computers.
S-Video
The S-Video connection is also commonly found on TVs and projectors, but solemnly on a desktop or laptop computer. This connection is a small step up from composite video, but is nearing obsolescence.

Connecting computer and projector or TV After you've identified what connections are available on both your computer and TV or projector, you're ready to connect the cables. If the same connections are not available for both the computer and TV or projector, you'll need to purchase a video converter cable that converts one signal into a compatible signal.

Desktop Computers For a desktop, you simply need to plug the cable into the computer and output device. If you don't see an image, you may need to change the display using the following steps.
  1. Press the Windows Key.
  2. Type Adjust screen resolution and press Enter.
  3. Find Display and click the down arrow on the right-hand side of the box.
  4. Select the appropriate output device.
  5. Click Apply then OK.

Laptop Computers If you're connecting a laptop computer to a TV or a projector you'll often need to "send" the video signal to the display device. The key sequence to do this varies depending on the laptop; but usually it's either: Fn + F3, F4, F5, F8, or F9. For example, pressing and holding Fn + F3 at the same time on my laptop sends the video signal to my connected TV instead of the laptop's screen. The corresponding key used with Fn may be labeled as CRT/LCD or have a picture of a monitor on or close to the key. Additional help and information with switching the laptop display can also be found on the link below.
Switching TV inputs Finally, if you're connecting a computer to a TV make sure it has been switched to the correct input. For example, if you connected an HDMI cable to your computer and the "HDMI 2" port on your TV, you'll need to switch to the "HDMI 2" input. This action can be accomplished by pressing the input button on your TV remote until the correct image is displayed.

Hooking up projector to laptop with only HDMI port


The PG-F320W has a DVI-I port between the VGA/Component input and the VGA output. You will need an HDMI to DVI cable or a HDMI to DVI adapter and either an HDMI or a DVI cable. If you use the audio input of the projector, you will also need the audio cable between the computer and the projector. (Make sure to disable the HDMI as the audio playback device. In Windows, go to the Hardware and Sound Control Panel. Then go down to Sound and Manage Audio Devices. Click on the Playback tab and check your output device. Click on Start for Windows 7 and earlier, Windows Key + X for Windows 8. Then select Control Panel.)

Monoprice.com has good prices for most cables. The HDMI to DVI cables are here: http://www.monoprice.com/Category?c_id=102&cp_id=10231 .

The manual for the PG-F320W is available here: http://www.sharp-world.com/products/data_projector/pgf320w/pdf/PGF320W_ex1_en.pdf . See page 21 for the DVI cable connection information. See page 61 for video resolutions that the projector can handle.

I hope this helps.

Is the 42" philip plasma


If you really want, you can use an old CRT TV as a monitor provided you get it connected.... so your plasma... YES. If your PC has a DVI port, you could use a DVI - HDMI cable to connect. If your PC does NOT have a DVI port, you could install a video card that does... better yet, get a video card that has a HDMI port. This way, you'll only need a HDMI cable to connect the PC to the TV for audio and video.

How can i use dvi port


DVI stands for (D)igital (V)ideo (I)nterface.

DVI is a new form of video interface technology made to maximize the quality of flat panel LCD monitors and high-end video graphics cards. It is a replacement for the P&D Plug & Display standard.

you can connect high definition monitor , LCD projector , LCD T.V to a DVI port

There three kind of DVI connector
1. DVI-D (Digital)
2. DVI-A (Analog)
3. DVI-I (Integrated Digital/Analog)

DVI-D format is used for direct digital connections between source video (namely, video cards) and digital LCD (or rare CRD) monitors

DVI-A - High-Res Analog
DVI-A format is used to carry a DVI signal to an analog display, such as a CRD monitor or and HDTV

DVI-I - The Best of Both Worlds
DVI-I format is an integrated cable which is capable of transmitting either a digital-to-digital signal or an analog-to-analog signal, but it will not work transmitting a digital-to-analog or analog-to-digital signal.


How to Recognize These three types of DVI Cable
There are two variables in every DVI connector cable, and each represents one characteristic.

The flat pin on one side denotes whether the cable is digital or analog:
A flat pin with four surrounding pins is either DVI-I or DVI-A
A flat pin alone denotes DVI-D

The pinsets vary depending on whether or not the cable is single- or dual-link:
A solid 27-pin set (rows of 8) for a dual- link cable
Two separated 9-pin sets (rows of 6) for a single-link cable

I have a HP m7570n. How do I use a flat screen tv as a monitor


This depends on the TV's available inputs. The Pavilion m7570n has only a VGA output in the standard configuration.

Thus if the TV has a VGA port, turn off the computer and the TV. Then connect a standard VGA (RGB or D-sub 15-pin) m/m cable between the computer and the TV. To use the TV speakers, connect a 3.5 mm audio patch cable between the computers Line-out (green speaker port) to the VGA audio in. Turn on the TV and set the input to VGA (with the Source or Input button on the remote or the TV). Then turn on the computer. Windows XP should find the correct resolution to work with the TV. (If you turn on the TV after turning on the computer, you may get an unsupported signal. Press Ctrl-Alt-Del twice to restart the computer.) If it doesn't work, you may need to connect a different monitor and set the computer to a low resolution before connecting the TV and the computer.

If the TV only has composite or component video inputs, you will need a VGA to video converter (http://www.svideo.com/pctocomponent.html for example). A VGA to component cable will not work; those are for projectors that read an RGB input. TVs interpret YPbPr.

If you have added a video graphics card, you may have an HDMI and/or DVI port(s) on the card. In that case, check the specs of the TV. Some TVs will support HDMI or DVI-HDMI inputs from a computer. Others will not (since computer video signals are not the same as the signal from a set-top box). If you use a DVI-HDMI connector, make sure to use the HDMI port labeled for DVI and connect the audio cable as with the VGA connection. If you use an HDMI connection, you may need to set the sound properties to that of the HDMI port. (Find the control panel item for sound (under Hardware) and then select Manage Audio Devices. Set the Playback properties. If it doesn't work, use an audio patch cable.) Some TVs have RCA audio inputs for the HDMI-DVI connector. In that case, you will need a female 3.5 mm to RCA M/M adapter (if you use a 3.5 mm patch cable). There is a similar device if you want to use an RCA audio cable. You may need to enable the video ports on the graphics card before swapping monitors.

Some video cards have a TV out. In that case, connect the appropriate connector (should come with the video card). Then connect to the component, composite or S-video input on the TV.

Again turn off the TV and the computer before making any connections.

You will probably need to provide your own cables for must of these connection options.

I hope this helps.

I want to connect this pc to LCD TV want know where is the audio output of the computer


LCD TVs are the best at showing computer graphics, so many come with PC video connection ports by default. If it does have one of these ports, all you need to do is get a cable to connect to it. This is usually a male-male cable. Be warned, however - stores like Best Buy and the like tend to horribly overcharge for cables. Check prices online at places like www.newegg.com - I found some from $6-$10 with $5 shipping. They'll probably be $25 minimum in a store. Also, if it's a DVI connection, don't get a DVI-A cable - that's for analog connections. DVI-D is for digital connections (specifically for connecting to LCD screens) and DVI-I cables are for both, but be sure to get a DVI-D cable.

Check out this link and look at the picture of the DVI-D and DVI-A connectors:

http://www.pacificcable.com/DVI.htm#DVI_Hoods

My video card has a DVI-I output, but my monitor only has a DVI-D input, so I can't use a DVI-I cable on it (DVI-A and DVI-I both have 4 extra pins that DVI-D doesn't).

If it's got a VGA port then whoop-de-do. There's only one type of VGA cable anyway. ^_^ Source(s): http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&DEPA=0&Description=dvi+cable&x=0&y=0

use a vga to vga cable. if your HP has a 13 pin serial conector. (looks like a trapezoid), use that.
If not you may need a dvi to vga cable.
if not, the projector may have two ports on the back - use computer in - not monitor in.

DVI will not recognise now ?


Presumably, you're going directly from DVI port on computer to DVI port on Z2?. Here is a Q&A list based on all the possible sceanrios for this hook-up...

Q1: Is it DVI-D or DVI-I (with unencrypted DIGITAL output from graphics card)?
A1: Choose 'Input 2', then 'RGB(PC Digital)' on Z2.

Q2: Is it DVI-D or DVI-I (with HDCP-encrypted DIGITAL output from graphics card)?
A2: Choose 'Input 2', then 'RGB(AV HDCP)' on Z2.

Q3: Is it DVI-I or DVI-A (with ANALOGUE output from graphics card)?
A3: Choose 'Input 2', then select 'RGB(Analog)' on Z2.

After making sure the correct 'Input 2' is chosen to match the signal coming from the card's DVI port, make sure your card is outputting a suitable screen resolution that the PLV-Z2 can display correctly, e.g... 1280x720 (native, and preferable!); 640x480; 800x600; 1024x768 (choose this if you don't have 1280x720); 1280x1024, etc. Also, if you have multiple refresh rates availble for the resolutions, choose 60Hz.

You should end up with an image.
