Setup Basics

Common setup questions

How does calibration work?

Calibration in AcuityMaster is deliberately simple: you measure your lane’s patient-to-screen distance and enter it during setup, and the software auto-calculates every letter size from that number. That single measurement is what keeps a 20/40 line a true 20/40 line, so measure it carefully — from the patient’s seated eye position to the display face — and re-enter it any time the chair or monitor moves. This is the same geometry that underpins the ANSI Z80.21 and ISO 8596 standards AcuityMaster is built to. Converting a projector lane for the first time? Start with the digital eye chart setup guide.

How do I set up a dual-monitor exam lane?

Run the chart full-screen on the patient-facing display and undock the control menu onto the technician’s screen — the undockable control menu exists precisely for this workflow, so the operator can change charts, lines, and optotypes without anything flashing in front of the patient. Configure your operating system to extend (not duplicate) the desktop across the two displays. A single-display setup also works for smaller rooms. The features page shows the dual-monitor workflow in context.

My exam room is short — what about mirror mode?

AcuityMaster includes a mirror mode for compact exam lanes: the display shows a reversed chart that the patient views in a mirror, letting a short room behave optically like a longer one. When calibrating a mirrored lane, the distance you enter is the full optical path the patient’s eye actually travels — eye to mirror to screen — not the straight-line room length.

What hardware and browsers do I need?

AcuityMaster Legacy runs on Windows 7 / 8 / 10 / 11 desktops. AcuityMaster Cloud runs in any modern browser — Safari, Chrome, Firefox, or Edge — on Mac, Windows, and iPad, with no installation. The complete, current spec list lives on the system requirements page; check there first if you’re buying new lane hardware.

Troubleshooting

If something looks wrong, start here

Letters look too large or too small

This is almost always a calibration-input issue rather than a software fault. Re-measure the actual patient-to-screen distance and confirm it matches what was entered during setup; a monitor that has been moved even slightly, or a mirrored lane calibrated with the room length instead of the full optical path, will shift every letter size on the chart.

Display or image-quality problems

Check the basics in order: the display is set to its native resolution, brightness has not been changed by staff or an auto-dimming setting (consistent luminance is part of ANSI Z80.21-compliant testing), and no window glare or reflections are washing out contrast at the patient’s eye position. If optotypes look soft or blocky, resolution settings are the usual culprit.

Browser or launch problems (Cloud)

Make sure the browser is a current version of Safari, Chrome, Firefox, or Edge and that the device meets the system requirements. A quick browser restart resolves most transient display-connection oddities in extended-desktop setups.

Still stuck?

Check the FAQ — it covers 40+ questions on licensing, hardware, Mac support, and standards — and the glossary if terminology is the sticking point. The resources library has longer-form articles on visual acuity testing itself.

Support Channels

How to reach support

AcuityMaster support is deliberately direct. There is no ticket portal and no offshore call tree — questions go to Dr. Mark S. Brown, MD, the oculoplastic surgeon who has practiced since 1998 and built AcuityMaster in 2012 to fix problems in his own exam lanes. That means the person answering your question understands both the software and the clinical context you’re asking from.

Email: [email protected] — best for setup questions, license issues, and anything with a screenshot.
Phone: (251) 216-2825 — best when a lane is down and you need to talk it through.
Web: the contact page has a form if you’d rather not open your email client.
