SOURCE: No signal when connecting PC to TV

This happens to almost every laptop I know. Here are several solutions:
1. You need to manually enable video on tv by pressing two buttons on your laptop keyboard. The first is "Fn" (at the left bottom). The second depends on your laptop manufacturer. Look at the function keys. F1....F12 for the LCD/CRT or the corresponding sign. Press and hold Fn and press second button. Sometimes you need to press second button several times. This means you need to cycle through all available options to enable Laptop's screen and TV screen at the same time (clone).
2. Intel Extreme Graphics video cards sometimes doesn't support a procedure described above. You need to find intel video card options manager running at the sys-tray (right bottom of your screen near the clock). Right click on it. Select Graphic Options -> Output to -> Laptop + ... clone (or something similar)
Note that not all video cards are capable of showing the movie on media player at the same time. You need to choose Laptop or TV

SOURCE: My Vizio 32" Flat Screen suddenly turned blue and "no Signal"

Check the cable connector. If it is OK then the turner has gone bad. Replace main board will fix it.

SOURCE: ive connected the vga cable and still get "NO SIGNAL" msg.

If the resolution of the source of the RGB signal is outside of the range of the set, you will get this mesage. The supported resolutions are listed in the owner's manual. Verify that you have a signal within that range. If you do, please post your source of the video here and we'll look further.

Thanks,
Dan

SOURCE: I can not get TV to pick signal from PC

I had a problem where my VO22L was giving me a "No RGB Signal" "The Power Will Be Turned Off" message when I had it in RGB mode (with VGA input from my PC). Anytime I left my PC on and turned off the power of this unit, I got this message. I just got off the phone with a very friendly and patient Tech Support woman at Vizio, who talked to several different techs who all came up with things that didn't help. Finally, while we were talking, she came up with the idea of going into the settings menu and doing a "System Reset" to see what happens. What do you know, it worked!

To anyone else having this problem, try this. With the PC and TV on, in RGB mode, go into the menu screen with the remote. The far right tab is "Setup". Use the arrow keys to go down to the "System Reset" option. When prompted "are you sure" select "Yes". I powered the monitor off and on, and the problem is gone. Now if it happens again, I know what to do.

Instructions
    • 1 Decide if you want to watch the television on your computer or use the TV as a larger monitor. If you want to view the contents of the TV on your laptop, you need a video card connected to to the computer. These cards can either be inserted through the express PCI card slot on the laptop, or via USB cable. Make sure the video tuner card supports component video.
    • 2 Connect the DVI-to-component cable into the DVI port if you want to use the TV as a large monitor for your laptop. However, if you have a VGA port, plug the VGA-to-component cable into the VGA port.
    • 3 Plug the RGB component cables into the component side of the DVI- or VGA-to-component cable. If you want to watch the TV on your computer, insert the RGB cables into the TV video card.
    • 4 Plug the other end of the RGB component cables into the TV. If you are using the TV as a monitor, plug the cables into the "Component In" ports. However, if you are sending the TV signal to the computer, plug the cables into the "Component Out" port (the other end of the DVI- or VGA-to-component cable that you connected to your computer in Step 2).
    • 5 Power on the TV. If you are using the TV as a computer monitor, press the "Video" button until "Component Video" appears on the screen. If you are watching TV on your computer, launch the television viewing software that came with the TV tuner card. You can now see the contents of the TV on your computer.

Ibm thinkpad wont connect to LG TV


Lower the screen resolution to 720 dpi.

Another issue is the reference to RGB. Is it the 3 cable (YPBPR) or the standard 15 pin VGA? You may need a converter.

I am trying to connect my acer PC to a tv but get


The inputs on a TV are normally via the ariel and go into a pre-amp

To get a signal in you, would again, normally connect to the RGB or Video in which bypasses the pre-amp.

The VGA cable will be outputting a digital signal which a monitor will understand but a TV will not as it prime supply is via an analog signal

You may be able to get a connection if you process the signal through a freeview box which changes the signal from analog to digital

Can i connect toshiba satellite a205 to tv?


Yes VGA carries RGBHV--RGB and Horizontal and Vertical Sync information along with DDC info where available.

Now is that port on your TV a d-sub 15 pin standard VGA connector?
http://en.wikipedia.org/wiki/VGA_connector

If it is, then yeah you should be able to output VGA from a PC to the TV with a proper cable.

However if the TV has DVI or HDMI connections on it, it's better for you to connect it that way. DVI/HDMI is a digital signal and if it's a digital-based display tech TV, then you're better off using that. Also if the TV does resolution above 1360x768 (i.e. if it does 1080p) you can get higher resolution by going via DVI/HDMI...

LG 37LC7D Connect to VGA from a PC


Your right. I just had the same "Invalid Input" issue as well and it completely relates to the resolution compatability with any VGA or HDMI connection. Check the LG website for the online manual if you don't have it and see the section on RGB-PC cable. There is a table that incdicates the Resolutions the LG product is capable of displaying.

Thanks for the help.
