I'm trying to hook my laptop up to my tv. I've installed an RGB cord. I'm on input 4 on my tv but I still can't get my tv to find my laptop

1. Get an RGB cable.
2. Plug one end of the cable to the laptop VGA/RGB port.
3. Plug the other end of the cable to the RGB/PC input port of the TV.
4. Select the output of the laptop to the VGA/RGB port.
5. Press the Video button (usually with a sign of an arrow inside a circle) and choose PC.

I checked all the inputs, but still no picture or sound

Make sure all connections Power ,HDMI and any other connecting leads have secure dust free connections also check each lead for any kinks / bends .
Connecting a Toshiba Satellite Laptop to a TV is an ideal way to enjoy videos, photos and other media on the laptop on a much larger screen.
Satellite Laptops can be connected to TVs using VGA, S-Video and even HDMI, though the TV has to have compatible inputs as well.

Connect the RGB cable or S-video cable to an open input on the TV.
Depending on the type of TV, it may or may not have a RGB input.
S-video may have to be used instead.
Connect the 1/4 inch to RCA Y-cable into the TV using the same input as the VGA or S-video cable.
Connect the other end of the VGA or S-video cable and the audio cable into the laptop.
The video ports are on the sides of the laptop.
The audio cable should go into the headphone jack of the laptop.

Can't do an s-video just hook up rgb/vga cable from laptop to tv and put the input to rgb/vga.

In order to connect your laptop to your TV using RGB, you need an RGB adapter. RGB is also known as component video; it breaks up a video signal into red, green and blue. laptops do not have RGB outputs. However, many laptops have VGA, DVI or HDMI outputs. An RGB adapter connects the single VGA, DVI, or HDMI cable to an RGB cable, which is actually three different cables tied together. INSTRUCTIONS:
1. Connect either the VGA, DVI or HDMI (in the order of increasing video quality) cable to the VGA, DVI or HDMI port on your laptop, depending on what is available. 2. Connect the other end of the cable to the side of the RGB adapter with the single input. 3. Connect the RGB cables to the red, green and blue ports on the other side of the RGB adapter. 4. Connect the other end of the RGB cables to an available component input on the back of the TV. 5. Tune the TV to the component video input you used through your television's menu. 6. Turn on your laptop. The laptop should now display on your TV screen.

Things You'll Need:

• 15 pin RGB cable
• Audio cable

Step 1
Connect the RGB cable to the Video Out jack on your computer.

Step 2 Plug the other end of the RGB cable into the RGB jack under PC In on the back of the television.

Step 3 Hook up one end of the audio cord to the Audio Out jack on the computer and plug the other end into the Audio jack under PC In on the back of the television.

Step 4 Turn on the television and press the "Input" button on the television or the television remote control. A list of input options will appear on the screen.

Step 5 Highlight "PC" using the up and down arrow buttons and press the "+" button to choose the computer input. The television will display whatever is on your computer.

The problem of course is not the computer since you communicate well when using the Samsung TV. The problem is your Sampo. The Video Ports are:
Composite Input (Shared w/ S-Video) RCA-pin x 2 S-Video Input (Shared w/ Composite) Mini DIN 4-pin x 2 Component Video Input RCA-pin x 2 Sets (Y/CB/CR, Y/PB/PR auto detect) DVI Input (with HDCP) DVI-D 24 pin x 1 RGB Input D-Sub 15-pin x 1
If the RGB WILL NOT COMMUNICATE, I suggest you try RCA/DVI/ or shared composite. You may need adapters, but with so many options, just try other methods.

I've been online looking for a solution to this problem and couldn't find a fix until today. I just got off of the phone with a Vizio Tech. He told me that some pc's have a way for the monitor to show the screen externally, and that there's usually a button, sort of like the input option on your TV but its an output button for a laptop in my case. It should look like a picture of a TV in and out of each other. Mine was located on the number four key. I had plugged in my wires and put the TV input on RGB. then on my laptop pressed the function key and number 4 key at the same time and what do you know, I had a picture on my screen. I almost gave up on my vizio but love it even more now. I hope this helps.

For No signal try- Updating your Video drivers, and making sure it shows a connection on your laptop ( by going to propertys on desktop and then dysplay)
For format try- Updating and or turning down the screen resulotion becuase the size differs on screen even if you think it shouldnt.

Cable TV: Connect the LCD TV to the cable with CATV and Digital cable. Preset the cable TV channels into memory with Auto Scan function when using a cable TV system. Make sure you set the INPUT SOURCE properly (TV, VGA, S-Video, etc)
