Technology has come a long way, though - the VP2290b was a thick and heavy behemoth that was extremely difficult to drive using the signaling technology of the time.

Plus, even the final revision of the T221 required being driven as either two monitors using one dual-link DVI and one single-link DVI or as four monitors by using four single DVI links. Even then, the internal refresh rate was a slightly annoying 48Hz.

The T220/T221 really were ahead of their time but convenience and standard size of the new generation of "retina" displays shows how far we've come.
