If you have the output from the computer to the computer input on the tv then all you have left is set the tv input on acc or what ever the the computer is run on.

What resolution are you using?  It might not work if it's set any higher than 1366x768.  And set the refresh rate to 60 Hz.

SOURCE: 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.

SOURCE: no picture when vga cable is connected

Most tvs can only handle a couple resolutions (ie 640x480) through the pc input. Even some HD tvs can only do 480. Check that your video is turned on and setup to the acceptable resolutions.

right click your desktop
go to properties
click settings tab
click on the 2nd monitor
make sure the box is clicked at the bottom
"extend my windows desktop onto this monitor"

SOURCE: my sharp tv is pc ready. I hook everything up and

There are a number of things to check here:

1) Verify that the resolution on the PC is set to a supported level for the TV. Usually the TV will show "no signal" if the resolution is out of range or the message "out of range" will appear.

2) You don't indicate whether you are connecting to a desktop or laptop. If a laptop, you may need to turn on the external monitor. This is done by using the function key and either F5 or F6 (the key should have a picture of a screen on it). Hitting this combination will toggle between the main screen with.without the external monitor.

3) Verify that the TV port is selected correctly (AV1,AV2 etc)

4) You will need a separate cable or the audio regardless of the system type. Also verify that the audio cable is in the corresponding audio input jacks for the video option selected.

If you have completed the above and it still doesn't work, please post the details about the computer being used and the exact cable setup that you have and I'll check into this further.


Thanks,
Dan

What resolution is the screen (max) and what are you trying to put into it? If the video output of the PC is too much it won't 'see' it sometimes... try lowering the PC resolution to that of the screen.

If it's a second monitor, you have to go into the screen settings on the PC and tell it to either 'mirror' (or duplicate) the existing monitor on it or extend the screen on another monitor.

Sorry I can't be more specific as I don't know what the screen or PC (computer) is...

restart pc in safe mode, change video back to standard VGA of HD VGA video. PC has to be in HDMI mode and your TV has to be PC mode. Use a DIV to HDMI connector or better yet HDMI to VideoPort if your TV supports it, HDMI almost never gives you the screen output you really want anyway.

How do I fix the error no vga input signal no dvi input signal monitor going to sleep


Check if you VGA is properly settled in the PCI slot. Try to take it out, clean the slot for dust.
If that doesn't help, it is well possible that you VGA is not working any more.

I can't connect my xbox360 to my sony pfm-42b2 tv


Keep in mind that your Sony IS NOT A TV, but a monitor instead. There is an actual XBOX360 VGA adapter that's available at most gaming retailers. It was initially designed for those who wanted to use their PC monitors for there console gaming. HDMI is NOT compatible with a VGA input as HDMI is a digital signal type and VGA is an analog type connection. You must also remember to have the XBOX set to a NON-progressive resolution (480i) if trying to hook it up using the standard XBOX video cables.

Trying to hook up laptop with haier tv using vga


Dod you use HOTKEYS on the laptop to tell it to send the signal the VGA outlet of the laptop? The hotkeys function can be set to turn off the laptop screen and only have external monitor to be the only display or it can be set to have both of them on.

Why won't my tv display my computer screen


Hi. The best way to hook your computers display to your LCD screen will be to use the VGA input socket. If your video card can support both S-video input and VGA, you can use either one but, the VGA is best for optimal resolution. This is the easy way to do this. Step one, connect the VGA cable to the computers video card and then, run the other end of this same cable to the VGA input slot on the LCD screen.Step 2, next you will make sure that the LCD's input selection is selected to show what is being transferred from the CPU video card by using the input button on the lcd remote control. The lcd(your tv) should be on VGA or PC input signal. Step 3, now, you Will have to also make sure that your video card is set to transfer this signal as well by pulling up your video cards software window and switch to the proper options. once this is done, you should get a signal. Be sure to use the VGA input/output ports on both the lcd television and your cpu for optimal transfer of the video stream. Here is a pic of your back panel. use the input port labeled I for good PC input quality.
