Question about LG 32LC7D Television

3 Answers

Connecting PC to TV

A while ago my computer screen died out and for a while now I have been connecting my dell xps with Vista to my LG 32LC7D Television with an RGB-PC cable. I did nothing to set this up, it simply worked the first time I tried it.
The quality has been excellent and what would happen was on the RGB-PC channel on the tv it would say "no signal" when my computer was shut off or if I had been inactive on the computer for a while. However when I turned it on (or if I just moved the mouse when I was inactive) it would say "invalid format" for a second then the image would pop up anyway, no problem.
for the past week however the image had sometimes become staticy or start to move around for a few minutes and sometimes the signal would go dead and after a few minutes of turning off the tv or unplugging and replugging in the rgb cable to the tv it would fix itself.
3 days ago though I lost the signal again and now it appears to have become permanent. I bought an S-video cable which is what I'm using to type this now, but compared to my rgb-cable the quality is not only horrible, but its really getting to my eyes.

What do you think the problem might be, and how can I fix this?

    Just an update. I know now how to fix the problem, but I don't know how to stop the problem from happening.

    How I fixed it was to go on my computer with the s-video cable and right click my desktop to personalize. I then clicked display settings while my s-video cable and rgb cable were plugged in even though the rgb cable wasn't showing a picture it did show as the second screen for my display settings.
    I think it was either when I "extended my desktop" to the second screen (the one connected to my rgb pc cable) or when I kept changing around the resolution on my second screen (and checking what happened) that I could finally see my desktop on my rgb connected screen. Then I just clicked in Vista to make my second screen "my main monitor" and when I went back to my rgb screen it worked.

    A few days later the problem happened again, and I had to shut down the computer manually unplug the rgb cable and turn it back on so it only detected the s-video cable and made that one my main monitor again so I could sign in.

    When I play around with the "display settings" like I did last time it will evantually turn back on my rgb screen (a little dim at first, but it fixes itself after an hour or so) so I know the solution.

    I just need to know how to stop it from happening altogether now.

Sorry guys sound is not ment to be transmited through a rgb cable its just for higher quality video you can use a the red and white RCA inputs to get sound to your tv but you need a headphone jack -rca cable or if you tv has a headphone jack just buy a cable with one headphone jack on both ends
hope this helps

I'm trying to connect my Dell xps pc M1530 to my samsung lg tv. I have a 15pin vga cord connected. Still not working. Can you walk me through these steps?


After connecting the VGA cord, try the following:

  1. 1. On our laptop, go to display settings (right-click on desktop > properties) to see if you have the ability to switch to different monitors.
  2. On your TV, check if you have to switch through connection type (HDMI, VGA, etc...)
Hope this helps.

Need drivers to run windows 98se on dell xps m140

Microsoft (and Dell) stopped supporting Windows 98 a few years ago -- it lasted for over TEN years! So, it is *NOT* likely that you will find drivers for any computer that was "designed for Windows 2000" or "designed for Windows XP" or "designed for Vista".

So, in general, it is a _bad_ idea to connect any computer running Windows 98 to the Internet -- Microsoft has issued many "security-fixes" in the 4 years after they stopped supporting Windows 98 and Windows ME.

How do i hook it up to my tv?

Hi ,
My suggestion is first of all lower the screen resolution to minimum. Some tvs and monitors do not support high resolutions. After you see picture on the tv screen you can adjust resolution to the highest supported by tv.

Press Fn+F8 key after connecting to the S-video display device.
Hope this helps, if not, you may need to download latest driver for your video card, or latest software to manage displays
