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.
yes you can if you have a tv tuner connected to your projector. some projectors have a built in t.v tuner in them if yours does not have one built in you can buy a cheap t.v tuner and connect it to your projector by a hdmi cable or rca cables. and you can do the same with your laptop you can connect your laptop to your projector via the hdmi port on your laptop
I had the same problem. The projector works wonderfully connected to my iPhone (with an adapter), and connected to other kinds of laptops, but not with mine. Apparently the projector is not compatible with every laptop. I had to connect my projector to my laptop via a Netgear PTV1000 streaming player in order to use it.
You connect to the player wirelessly. Then use the HDMI cable to connect the player to the projector. Streaming Players
I happened to already have the player so I didn't have to purchase a new device. I hope this helps you.
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.)
To my knowledge there are no video drivers to output video on a Mac USB port in the Mac OS system. There are however, devices that connect to the USB port that will give video out on Conventional (VGA, DVI, HDMI, etc) connectors.e.g. http://www.newertech.com/products/viddu2dvia.phpMost projectors connect via VGA - what Projector are you using?
you should try shutting down your laptop, plugging in the interface cable for the projector and then powering on the laptop. This solution works with some projectors and all HDMI computer to External video source connections. (I say all because I have yet to find a combination that this didn't work on for HDMI)
