1 Requires PowerDesk 2.03 or later, and ATI Catalyst 7.1 driver or later
2 ATI Radeon graphics disable D3D caps in desktop resolutions above 2048x1536
3 In Windows 2000 and XP, modes above 2560x1024 (2 x1280x1024) are available only in 16bpp. All compatible modes are available in 32bpp in Windows Vista.
4 In Windows 2000 and XP, modes above 2048x768 (2x 1024x768) are available only in 16bpp.
5 In Windows Vista, the maximum available resolution is 2048x768 (2x 1024x768).
6 Under Windows 2000 and Windows XP, DualHead modes can be enabled through the TMET application.
7 Please run the Matrox GXM System Compatibility Tool to ensure that your GPU is capable of achieving this resolution. Some ATI FireGL and ATI Radeon (pre X1000 Series) GPUs support a maximum resolution of 2400x600.
The "maximum resolution" is defined as the single monitor resolution multiplied by the number of monitors used in a DualHead (two monitor) or TripleHead (three monitor) mode. For example, with DualHead2Go, 2560x1024 is the total resolution across two monitors, each monitor running at 1280x1024 resolution.
"2D Windows applications" refers to the maximum resolution that office applications can be set to for business use (ie. Email, MS-Office, etc).
"3D fullscreen" refers to the maximum resolution that a fullscreen 3D video game can run.
Under Windows 2000, when TripleHead2Go is connected to a notebook only the 3 external displays will be active - the LCD screen will be disabled.

**Download the GXM Control Panel to access all DualHead and TripleHead resolutions.
1 An Apple™ Mini-DVI to VGA adapter is required to connect to the VGA input of the DualHead2Go or TripleHead2Go device.
2 ATI Mobility Radeon X1600 may support a limited resolution list when the notebook LCD is active. This can be corrected by updating to the latest ATI drivers and EFI through the Mac OS Software Update utility.
3 Only iMac 17" equipped with ATI Radeon X1600 can achieve the maximum resolution, systems equipped with Intel GMA 950 are limited to 2048x768 (2x 1024x768) and are not supported by TripleHead2Go Analog Edition.
4 With ATI Radeon X1900, the maximum resolution cannot be achieved if a DualLink monitor is connected to the graphics card in addition to the DualHead2Go or TripleHead2Go.
5 ATI Radeon 9600 and 9650 support a maximum resolution of 2400x600 on TripleHead2Go and 2560x1024 on DualHead2Go.
