Matrox has announced the Parhelia DL256 PCI, a PCI graphics card with 256MB of RAM that’s designed to be used with high-resolution LCD displays that use dual links, such as Apple’s 30-inch Cinema HD Display.

LCD monitors with high native resolutions, such as the 2,560-x-1,600 30-inch Cinema HD Display, generally require two DVI connections to provide the video signal – which in turn requires a specialist graphics card or cards.

The Parhelia DL256 PCI is a 64-bit, 66MHz card that can be fitted to any 32/64-bit PCI or PCI-X slot. It features dual 400MHz RAMDACs and supports dual DVI resolutions up to 2,560x-1,600, as well as VGA displays up to 2,048-x-1,536.

As well as running a high-resolution LCD display, the card can also run a separate S-video or composite video output for previewing media from Premiere Pro, After Effects, Photoshop, Combustion, 3DS Max and LightWave 3D on a PAL monitor.

The Parhelia DL256 PCI costs $699 (around £375) in the US. UK pricing has yet to be announced,
