Quad Super Extended Graphics Array

A display resolution of 2560 × 2048 pixels with a 5:4 aspect ratio.

QSXGA (Quad Super Extended Graphics Array) is a display resolution of 2560 × 2048 pixels with a 5:4 aspect ratio. Grayscale monitors with a 2560 × 2048 resolution, primarily for medical use, are available from Planar Systems (Dome E5), Eizo (Radiforce G51), Barco (Nio 5, MP), WIDE (IF2105MP), IDTech (IAQS80F), and possibly others.

Recent medical displays such as Barco Coronis Fusion 10MP or NDS Dome S10 have a native panel resolution of 4096 × 2560. These are driven by two dual-link DVI or DisplayPort outputs. They can be considered to be two seamless virtual QSXGA displays as they have to be driven simultaneously by both dual-link DVI or DisplayPort since one dual-link DVI or DisplayPort cannot single-handedly display 10 megapixels. A similar resolution of 2560 × 1920 (4:3) was supported by a small number of CRT displays via VGA such as the Viewsonic P225f when paired with the right graphics card.
