The PC’s display resolution may be set too large, such as 1,600 x 1,200 pixels. Alternatively, the computer’s graphics drivers may not be fully compatible with VESA (Video Electronics Standards Association) standards. Determine the projector’s supported resolution using its label or users manual. Set the PC’s video resolution to match it. For example, in Windows XP, right-click a blank part of the Desktop and then choose Properties. Under the Settings tab, adjust the Screen Resolution slider. Click Apply and OK. The Settings tab in Display Properties also holds a link to your video card’s driver settings: the Advanced button. Look for settings here that enable your graphics card to send out a VESA-compliant signal. Update your drivers and look for help on the card and/or graphics chip manufacturer’s site, if necessary.
