Dell P1110 UltraScan 21" Trinitron CRT Monitor 0917R Dual VGA HD-15 Color

The Dell P1110 UltraScan is a 21-inch color CRT monitor built around Sony's Trinitron aperture-grille tube technology. Unlike shadow-mask CRTs, the Trinitron design uses a single cylindrical lens and vertical phosphor stripes to produce sharper horizontal detail and higher brightness — a meaningful advantage for graphics-intensive work, desktop publishing, and CAD. Dell part number 0917R, the P1110 was positioned as a high-end workstation display when it was current, and it carries dual HD-15 (VGA) inputs labeled HD1 and HD2 on the rear, allowing two computers to be connected simultaneously and toggled between via the front-panel OSD controls.

Applications

The P1110 UltraScan was aimed at professional workstation users who needed maximum screen real estate and image accuracy in the late 1990s — a time when 21-inch CRTs were the largest desktop displays available and were standard equipment in graphics studios, prepress and desktop publishing shops, CAD/CAM workstations, and financial trading desks. Trinitron monitors from this era are still sought after by retro computing enthusiasts and users running legacy workstations (SGI, Sun, early Mac Pro, HP PA-RISC) that output analog VGA or sync-on-green signals, as well as by certain professional video and broadcast users who prefer the color accuracy and motion rendering of a high-quality aperture-grille CRT over modern flat-panel alternatives. The dual-input switching capability made the P1110 practical in multi-computer setups without requiring a KVM switch for the display.
