Ultra-high resolution monitors differ from conventional monitors significantly in the display interface to be supported because conventional display interfaces and graphics subsystems cannot provide enough performance to fully exploit ultra-high resolution monitors. The T221 22.2" 9.2M-pixel 204-DPI TFT-LCD monitor can support various display interfaces to support various graphics subsystems/applications, from a PC cluster to a single PC with a commodity graphics card. This paper compares the architecture of the T221 monitor with its predecessor and discusses possible future trends based on our development experiences.

We discuss a high‐functional digital monitor interface, called Digital Link, which can support very high resolution monitors, high‐level control of monitor functions, and flexible monitor connections. This interface is essentially an upper layer protocol and takes advantages of the physical layer of existing digital interfaces. This paper also describes a prototype system that we have developed to evaluate various aspects of the protocol.
