CRT Terminator Digital VGA Feature Card ISA DV1000

A digital video expansion for your IBM PC/XT and PC/AT and compatibles.

Say goodbye to CRTs and analog video, and enjoy a pixel perfect digital output from your existing VGA adapter!

Introduction

CRT Terminator is an 8-bit ISA add-on card that outputs a native DVI-D video signal sourced from the digital VGA Feature Connector bus available on many VGA adapters. A 26-pin ribbon cable is used to internally bridge the VGA adapter and CRT Terminator to produce a clean artifact free digital video signal from your existing video card.

CRT Terminator then upgrades this video signal to be compatible with modern digital flat panel displays.

Screenshots

The following 1600x1200 resolution images were captured using OBS with a StarTech.com USB3HDCAP DVI-D video capture box from software running on the 486 PC shown above.

For those interested in peeping pixels close up, here are two shots of the pixel grid taken from an ASUS ProArt PA248QV display.

For video modes that do not have the possibility of pixel perfect upscaling, CRT Terminator's MultiMode feature carefully tunes a balance between aspect ratio and pixel correct upscaling.
