Matrox Electronic Systems LX G450, LE G450, DVI G450, PCI G450 manual Can’t view video

Problem	Can’t view video
Cause	Your display settings may be too high.
Solution	Try lowering your display settings (resolution, color palette, and/or refresh rate). For
	information on changing display settings, see “Display setup”, page 9.
Cause	Under certain conditions, certain video may not be viewable with your secondary display.
Solution	Try using your main display instead.

Problem	Mouse pointer flickers or disappears when it’s over a video window
Cause	You may be using a customized mouse pointer. Windows draws customized mouse pointers
	in a way that may cause them to flicker or disappear while they’re over a video window.
Solution	Windows 98/Me/2000/XP – Use default Windows mouse pointers:
	1	Windows 98/Me/2000 – Click Start # Settings # Control Panel.
		Windows XP – Click Start # Control Panel # Printers and Other Hardware.
	2	Double-click the Mouse icon, then click the Pointers tab.
	3	In the Scheme box, select (or reselect) “(None)”, then click OK.
Cause	You may be viewing digital video with the secondary display of your DualHead-supporting
	graphics card. On a secondary display, mouse pointers are drawn in a way that may cause
	them to flicker or disappear while they’re over a video window.
Solution	View digital video with the main display of your DualHead-supporting graphics card.
