Wide Quad Ultra Extended Graphics Array

A display standard that supports a resolution of 3840 × 2400 pixels, which provides a 16:10 aspect ratio.

WQUXGA (Wide Quad Ultra Extended Graphics Array) describes a display standard that supports a resolution of 3840 × 2400 pixels, which provides a 16:10 aspect ratio. This resolution is exactly four times 1920 × 1200 (in pixels).

Most display cards with a DVI connector are capable of supporting the 3840 × 2400 resolution. However, the maximum refresh rate will be limited by the number of DVI links which are connected to the monitor. 1, 2, or 4 DVI connectors are used to drive the monitor using various tile configurations. Only the IBM T221-DG5 and IDTech MD22292B5 support the use of dual-link DVI ports through an external converter box. Many systems using these monitors use at least two DVI connectors to send video to the monitor. These DVI connectors can be from the same graphics card, different graphics cards, or even different computers. Motion across the tile boundary(ies) can show tearing if the DVI links are not synchronized. The display panel can be updated at a speed between 0 Hz and 41 Hz (48 Hz for the IBM T221-DG5, -DGP, and IDTech MD22292B5). The refresh rate of the video signal can be higher than 41 Hz (or 48 Hz) but the monitor will not update the display any faster even if the graphics card(s) do so.

In June 2001, WQUXGA was introduced in the IBM T220 LCD monitor using an LCD panel built by IDTech. LCD displays that support WQUXGA resolution include: IBM T220, IBM T221, Iiyama AQU5611DTBK, ViewSonic VP2290, ADTX MD22292B, and IDTech MD22292 (models B0, B1, B2, B5, C0, C2). IDTech was the original equipment manufacturer that sold these monitors to ADTX, IBM, Iiyama, and ViewSonic. However, none of the WQUXGA monitors (IBM, ViewSonic, Iiyama, ADTX) are in production anymore: they had prices that were well above even the higher end displays used by graphic professionals, and the lower refresh rates, 41 Hz and 48 Hz, made them less attractive for many applications.
