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 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.


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.


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.



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.

If you connected the desktop with a hardwire connection (ethernet cable or usb cable) and the laptop is connected wirelessly, then the Desktop needs to be "awake" for the laptop to print. What I did was connect the printer to the network with an ethernet cable to the router, either wireless router or standard. Then you have a seamless connection for both computers independent of each other.

Is your cable modem also a wireless router?

From my search on it, it is not a wireless router.

This means you need to attach a hub or a wireless router to your cable modem so that more than one computer can connect to the internet simultaneously.

Go out and buy a wireless router. Connect the wireless router to your cable modem.

Connect your desktop to the wireless router with an ethernet cable.

Then you should have internet on your desktop.

Let me know if this helps. Give me a good rating and vote for me please.

check if we are getting good ip address 192.xxxxxxxxxxxxxxxxxx
not the 169.xxxxxxxxxxxxxx

relese renew if 169.xxxxxxxx is the case

if no reply.. try using another cable and check the connections

YOU WILL NEED TO GET A WIRELESS ROUTER TO BE ABLE TO USE THE LAPTOP WIRELESS, iT IS A VERY EASY SET UP AND CONNECT THE DESKTOP WIRED AND THE LAPTOP WIRELESS TO A WIRELESS ROUTER.

only way I can think of doing that is if you used a cross over cat 5e network cable between the desktop and laptop and assigned static ip addresses to them so your desktop would have 192.168.1.2 and your laptop would have 192.168.1.3 both with subnet mask of 255.255.255.0 and on the desktop put the default gateway as the laptops ip address.

Not sure if you would have to use internet connection sharing on the desktop to get it to work as ive never done it that way.

Would be a lot easier to just connect the desktop via a network cable directly to your router ( assuming you have a router ) if not buy a router and use that instead.

Do you need to see the desktop or just share folders from each other? If the latter then you need to do the following:

Use Windows Explorer and select a folder you want to share. Right click and select sharing and security.

On the sharing tab click on Share this folder. Enter a share name ( I like to enter the PC name _folder name; Rick1_Downloads)

Click on Permissions. If your ok with everyone using the PC's and Laptops having access then highlight Everyone and click on Full Control.

Do this on each PC and Laptop.

That should be it or darned near close.

you can buy a cheap USB wifi adapter and connect the desktop wirelessly just like your laptop, this should do the trick.
or you can buy an access point to extend the range of the wireless network, you should not be moving the router itself this way.

I may be able to help with this...but I need a detailed description of how you have things connected between the XP desktop, the cable, modem, the Linksys router, and the laptop. Also, is the Linksys router new?

Typically, the wan port on the wireless router connects directly to the cable modem with a cat5 network cable....then the desktop pc connects to the router...on port 1 for example...with a similar cable. Once the wireless router is set up properly, the laptop should then be able to connect using wireless.
