The projector still displays from computer if is through s-video, but not through the vga. Have tested with two different new vista computers, same result. As soon as the vga cable is plugged into the projector the computer receives no signal. The projector works fine with xp run computers. Is there a patch or upgrade that will solve this problem?
Re: pd527 not displaying vga from vista run computer
Based on my own experimentation, I have found out that if I click on the “Connect Display” button from the Windows Mobility Centre, it will auto-detect whether a monitor or projector is connected via the external display port. If it does find a display, it presents you with a new screen with an option to “Duplicate my desktop".
a 6ya expert can help you resolve that issue over the phone in a minute or two.

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.
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.
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.
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.
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.
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.
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.
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.
Press the Windows Key.
Type Adjust screen resolution and press Enter.
Find Display and click the down arrow on the right-hand side of the box.
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.
There are 3 different types of analog video signal ports on your projector; s-video, composite video, and RGB. Which one of the three are you using to connect your PC to?
The projector's resolution rate is XGA [1024 x 768]
If you are using a VGA cable designed and capable of handling 640 x 480 resolution; then it will not support XGAs 1024 x 768 signal. On the other hand, if the coaxial cable you are using is a multi band one that is capable of supporting VGA and XGA resolution signals, most likely the problem is not with the cable- although I have come across brand new cables that are defective.
Please let me know if this helps or else we'll try another approach :)
Insert one end of the VGA cable into your Sony Vaio. This is located on the left side of your computer. 2
Turn off the Infocus projector before connecting the opposite end of the VGA cable into the projector. The VGA input slot is located in the back of the projector. 3
Turn on the projector and allow time for it warm up. 4
Change the video output source on your computer to display through the projector. Press the "Windows" button and then "LCD/CRT" button on your Vaio keyboard to change the display source. On a Sony Vaio, the "LCD/CRT" button is usually "F7." 5
Focus the projector to most effectively display content from your computer. You can manually focus the projector or press the "Auto focus" button on the top of the projector.
try another computer and see if the vga input is OK.
If it is then set the vista screen resolaution to 640x480 and connect a spare computer monitor on the pc vga out and check that the video is coming out the pc.
The iMac G5 and iMac G5 (Ambient Light Sensor) computers have a video out port located on the back of the computer, which will mirror video. Video mirroring means you can see the same image that is on the iMac G5's flat-panel display on an external monitor, television, or projector. Using the video out port, you can mirror video with a compatible VGA display using the Apple VGA Display Adapter. You can also use the video mirroring feature with a television or projector that has S-video or composite video connectors when you use the Apple Video Adapter. Both the Apple VGA Display Adapter (M8639G/A) and the Apple Video Adapter (M9109G/A) are available separately, and are needed if you want to use your iMac with a VGA monitor cable, S-video cable, or composite video cable. The video mirroring feature is "plug and play". Simply connect a VGA display, television, or projector to the appropriate adapter (see above), then connect the adapter to the video out port located on the back of the computer. When you connect the adapter to the computer, the screen may refresh momentarily as the computer prepares itself for the new video output. The computer tries to match the resolution of the built-in and external display. If there is no match, the computer changes both screen resolutions and may black out areas on the built-in display in order to match the capabilities of the external display. Important: To ensure that your iMac G5 automatically detects the external display or projector, be sure you plug the adapter into the external display or projector before you plug it into the iMac G5. You can switch resolutions and frequencies for both the iMac G5 flat-panel display and the external display, television, or projector using Displays preferences. Want to watch a DVD movie disc on a television that's connected to your iMac G5? Select a 720 x 480 NTSC (in the United States) or 720 x 576 PAL (in Europe and other regions) resolution in Displays preferences. Tip: Because of the display limitations of most televisions, the images displayed on a television screen are usually not as high quality as those on the built-in display or an external monitor.
