PC laptop projection problems


If a laptop is connected through the VGA cable to the projection system and there is no image on the screen:
1) Press and hold Fn, then press F8 (Dell laptop method) to toggle between the available display modes. There are normally three display modes available; laptop display only, laptop and projected image, or projected image only. Please be aware that switching between modes can take a few seconds to occur.
2) If the above does not correct the problem, be sure the laptop is connected correctly and then reboot.

If the projected image is displaying wallpaper and the laptop display is normal, see Projecting from a Laptop you can only see your wallpaper or desktop and nothing else.

Should the projected image be off-color, blue or yellow tint, or is off-center, have the caller adjust the blue (possibly black) knob, Horizontal Position, on the Inline interface. The Inline interface is normally located above the top surface of the lectern and can be identified by following the VGA cable that is connected to the laptop computer. The Horizontal Position control should be slowly rotated while watching the projected image.

If the projected image is cut off on the sides or bottom, first check the resolution in Control Panel, Display and Settings. Should the display be set to 1280 x 1024 (SXGA, 5:4 aspect ratio), resetting to 1024 x 768 (XGA, 4:3 aspect ratio) should correct the problem
1280 x 1024 (SXGA) is a squarer image and will not display correctly when projected onto a 4:3 aspect ratio screen.
Name Pixel array Aspect ratio Comment
VGA 640x480 4:3
SVGA 800x600 4:3
XGA 1024x768 4:3
WXGA 1365x768 16:9 Wide-XGA; used for wide screen LC TV displays (beware: sometimes 1280x768 is called WXGA)
SXGA 1280x1024 5:4 This format is "squarer" than the others
UXGA 1600x1200 4:3
QXGA 2048x1536 4:3
