Mitsubishi Diamond Pro 87TXM 17in CRT Monitor 1600x1200 BNC VGA TFM8705SKHK

Mitsubishi Diamond Pro 87TXM 17in CRT Monitor 1600x1200 BNC VGA TFM8705SKHK

The Mitsubishi Diamond Pro 87TXM is a professional-grade 17-inch aperture-grille CRT monitor with a 16.0-inch viewable area, capable of a native resolution of 1600×1200 — unusually high for a monitor of this size and era. Built in January 1997 by Mitsubishi Electric in Japan, the 87TXM was positioned as a workstation and graphics-professional monitor, competing with other high-end CRTs of the mid-to-late 1990s. The unit in the photos powers on and displays an active color bar test pattern, as visible in the listing images.

Applications

The Diamond Pro 87TXM was designed for professional workstation use — graphic design, CAD/CAM, desktop publishing, and prepress work — where a sharp, high-resolution 17-inch CRT was the tool of choice in the late 1990s. The dual-input configuration (VGA HD-15 plus a full five-BNC Signal-B input) made it compatible with high-end UNIX workstations and graphics workstations from Silicon Graphics, Sun Microsystems, HP, and similar vendors that output RGB video over BNC rather than standard VGA. The 0.25 mm pixel pitch was among the finest available in this screen size, producing a noticeably sharp image compared to most consumer-grade CRTs of the era. Today, these monitors are sought by retro computing enthusiasts, vintage workstation owners, and users of legacy graphics hardware that outputs at resolutions or sync rates that modern LCD panels refuse to accept — the CRT's native ability to display virtually any sync signal makes it valuable for DOS-era gaming, vintage SGI or Sun workstations, and early 3D graphics card testing.
