LG 32LH20D wont display pc window.

Because your laptop needs it's display setting changing so your second monitor is active.
While on your desktop, right click once and a box will appear, choose "properties" at the bottom.
There you will see another box, choose the "settings" tab at the top right and this will show your display options.
Right click on the number two box and "attach" it.
You may also have to change the size of the display to fit your tv.
Hope this helps

check windows optional updates....or try booting up with tv already linked....ooo check the display settings for dpi and Hz some tvs wont go above 60Hz

Hi Donna.
Do you have an HDMI plug on your lap top?
If so, then buy one and connect it to your pc and tv. Change the tv's input so it is on HDMI and change the laptops display settings to projector.
(If it's windows 7) or another display setting that will display on both your TV and your lap top screens.

Hope that helps. Let me know..
Darcy

i have connect to my laptop to the TV thru' 15-pin VGA video connector and change my graphic card setting. I have sendyou a snapshot of the setting which are similar to the laptop.

no laptop stated or service tag
nor OS< opr.sys.
so the local screen is still OK
reload the video driver?
make sure power setting in CP are set to on all time no sleep.
make sure close lid, power settings is set to oFF. ?

You need to use the RGB input port on the TV

When you have them all connected, press the Fn key and while holding that down, press the F5 key, this will toggle the video output through all the choices. Give it a little bit of time, the vga graphics chip may need a few to send the signal to a larger display such as the tv.

You have to configure the settings for the external display (TV) in windows.(assuming that's your OS)
Go to control panel >display >properties >advanced and make sure the TV is selected and active as secondary display.

Verify that you get a picture on the TV when doing this, if you do - you're all set.
Restart the computer and the problem should be fixed.

If there is no display on your TV, HDTV, or Projector, please make sure that all of your connections are set up properly and that you have enabled the display in the Catalyst Control Center. The connectors that you will be using would be Svideo for TVOUT, DVI-to-HDTV (Component video), VGA-to-HDTV (Component video) for HDTV, and DVI, VGA, or Svideo for the projector.
Here are the steps to properly setup and enable TV, HDTV, or Projector:

• Turn off your PC and your TV, HDTV, or Projector.
• Ensure that your card was installed correctly, as per the Getting Started Guide.
• Determine if your TV, HDTV, or Projector has a S-Video (for TV), YPbPr for (HDTV), or VGA/DVI for Projector.
• Looking at the back of your PC, locate the needed connector or the supplied adapter cable; attach one end of the cable to your graphics card and the other to your second display.
• Turn on your second display then your PC.

If you are connecting an HDTV to your video card, please Click here for detailed instructions on how to set it up correctly.
Starting Windows with TV or Projector Display Enabled The TV screen may become scrambled during the initial Windows® logo display. This is only a temporary effect and your screen will be restored within a few seconds. During start up, your RADEON will go through a sequence of mode settings, during which your TV display will remain blank. This process takes only a few seconds and helps program the TV display.

• To enable the second Display
• Right-click anywhere on your desktop
• Click Catalyst Control center
• View
• Advanced view
• Display manager
• Detect Displays
• You should have the second display picture under “Attached displays currently disabled
• Drag it to the box on top of it
• Apply
• OK

If for any reason the second display does not get detected, please do the following:

• Open the CATALYST CONTROL CENTER
• Go to Display options
• Check “Force TV detection” *
• Apply
• OK

* Force TV: Allows you to force TV detection if the ATI driver does not automatically detect TV-out connected to the graphics accelerator.
Possible issues:

• Computer monitor loses sync when TV OUT feature is enabled
• Text appears blurry on TV
• TV OUT is black and white with a PAL-M or PAL-N television
• TV OUT is enabled randomly at boot, even with no TV attached
• Image on television is cropped using Overlay Theater Mode
• With Theater Mode-Overlay enabled in Clone Mode and selecting the "Swap Device" option results in the system restarting.
• Corruption may be noticed on an HDTV after setting the resolution to 1080i and enabling Overlay Theater Mode.
• When using an HDTV in extended desktop with theater mode enabled, the video does not display

In case the users display does not natively support HDTV display timings in the EDID, you can add standard HDTV modes so that the usual HDTV resolutions (720p, 1080i, 1080p) are listed in the Display Manager resolutions. You can also create custom HDTV timings to solve any kind of over-scan options (for cases when the windows desktop appears to not fit on the HDTV screen, and the outside boarder is cut off).
For more information on connecting your second display to your Video card, including supported output device combinations, please refer to your user’s manual.
