LG 32LG30 no signal when pc and tv r connected via rgb cord

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.

Connect VGA (D-sub 15 pin) cable from PC to TV (RGB PC) input jack. Connect audio cable from PC to TV. Set screen resolution on PC to be compatible with TV, such as 800 X 600 or 1024 X 768 etc. Select on the TV, the PC INPUT using the TV remote when ready to use as monitor.

Under PICTURE on the TV select SCREEN (RGB-PC). You can AUTO-CONFIG or you can set resolution manually to the same you set PC to. Other adjustments can be done here as well to get optimum picture on TV from PC.

I too am having the same problem. It works fine on my Samsung TV but no signal on my32lG60. If you find anything let me know. Larry [email protected]

CHECK YOUR GRAPHICS CARD DISPLAY PROPERTIES IE:

REFRESH RATE FREQUENCY 55HZ 75HZ ETC. YOUR TV MAY ONLY WORK WITH THE CORRECT REFRESH RATE AND COLOUR RATE CHECK YOUR USER TV MANUAL FOR SETTINGS

Reading the online manual - You should have the laptop connected by VGA - PC input
VGA Connection you need to select the correct input on the TV

• Select the RGB-PC input source on the TV using the INPUT button on the remote control.

you will need to set the laptop up to output to the VGA output, to do this - varies by different manufacturers - But often F4 or F5, with the FN key selects the VGA output - have a look at the F keys across the top of the machine and see if you can see a picture of a screen - then use the FN and that F key together to toggle between display it will change to <Laptop Screen Only><Laptop screen and VGA output><VGA output only> not necessarily in that order.
This is the support site for that TV http://www.lg.com/us/support/product/support-product.jsp

You need to tell your laptop to send the video signal to your rgb output interface by using your function keys. Usually Fn+F2 or F8.

You probably need a audio cable that runs from the pc audio out to the TV audio in. Radio shack has them so do a lot of hardware store and best buy.

Do you also have a computer monitor attached to the computer when attempting to use the HDMI?

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.

Same problem for me too!
