The pictures on my TV screen is bigger than that on my DELL laptop, so I lose some parts of the picture , how can I adjust it ? I have windows XP home edition and my LCD TV is made of SAMSUNG 2011.
Try opening up the display properties (right click desktop, display properties), and try the different resolutions. If it is a flat screen TV, try 1280x720, which is 720p. If your TV does 1080p, you can try 1920x1080.
Your TV might be in Overscan mode. Look for this option and turn it off. If you LCD tv is 1080p and your laptop is less you should be able to have alternating resolutions. Overscan usually zooms in the image about 5%.
