Some video adapters use a retaining clip, which must be moved to one side to prevent damage when removing the adapter.
Setting the video resolution to 640x480x16 colors in Device Manager is not the same as changing the hardware to a VGA adapter. You must change the adapter selection from the installed adapter, i.e. ATI, nVidia to a standard VGA adapter in the Display Properties dialog box.
Some Intel chipsets uses Dynamic Video Memory technology (DVMT) for video memory. The initial memory count can indicate less than expected system memory count. Click here to learn more about DVMT.
Signal cable extensions and keyboard, video, mouse (KVM) switches are not supported.
Some I-5 I-7 Intel processors do not support on-board video and must use a discrete video adapter, while some I-3xxx CPU provides on-board video. To determine your CPU capability refer to the Intel support site. http://ark.intel.com/
