Requirements

Runs on what you already own.

AcuityMaster is lightweight by design. If you already have a computer in your exam lane for your EMR, that's typically all you need.

System requirements

  • Windows XP, Vista, 7, 8, 10, or 11
  • .NET Framework 4
  • 1 GB RAM
  • 5 MB free disk space
  • Mac-compatible version coming in 2026

Dual-monitor setup

Most practices share one computer between their EMR and AcuityMaster. With a dual-output video card, the first display drives the EMR; the second drives the patient-facing AcuityMaster screen.

  • Video card with dual video output
  • 20–24" LCD/LED monitor with HDMI — readily available for around $150
  • For video fixation, choose a monitor with built-in speakers (HDMI carries audio)

Sample exam-lane setup

A single computer placed anywhere in the lane. The first video output runs to your EMR display. The second (HDMI preferred, DVI or VGA also work) runs to the patient-facing monitor — either directly in front of the patient, or behind the patient with a mirror in front.

All-in-one option

For a tidier installation, mount a refurbished all-in-one computer (such as a Dell OptiPlex AIO) on the wall. These are often available from Dell Outlet for under $350.

Standards we meet

Luminance. The standard for optotypes per ANSI Z80.21 specifies background luminance between 80–320 cd/m². Current monitors meet this.

Contrast. ISO 8596 requires that the luminance of the optotype is equal to or less than 15% of the background. Current LCD and CRT monitors meet this.

Color temperature. The standard requires white background light between 2500K and 7000K. Current monitors fall within this range.
