Go into your control panel. Select display. There will be a picture showing 2 screens. Select the 2nd screen, and lower resolution to it's minimum. Apply and test. Slowly increase till you find what your happiest with. Worked for me using a ASUS laptop and LG60'plasma.

Here's what worked for me with my Dell laptop and LG 37" tv: go into the display properties of your computer graphic card by right-clicking on the desktop. Make sure you've got it set up for dual display with the laptop as the primary and the monitor (your tv) as the secondary display. Then go into the display properties for the monitor and make sure that it's set to display full screen instead of maintain aspect ratio, then apply the setting.

My tv says invalid format when I plug my dell inspiron into it


Sounds like you may need to check your video drivers for an update, besides Windows itself find out what video you have Intel or Amd and update thru their website. It can also be that your tv is running at a resolution that your laptop might not support.However most new video drivers allow for custom resolution settings that can be applied besides the native ones in windows.If its a vga cable I almost can be certain that it is not allowing the native resolution of your display.Hdmi will automatically adjust it.Also try hooking the laptop up to a Pc monitor and check for a display if it works on the monitor you need a custom resolution for your tv. Also try a different input on the tv (if ones available) and check it.

You may need to use the S-video cable for video. Make sure video mirroring is disabled on the powerbook. Also, make the external monitor the primary display by dragging the menu bar to it in Displays preferences (Mac OS X) or the Monitors control panel (Mac OS 8 and 9).
