If you already have a computer in the exam lane for EMR/EHR, you can typically run AcuityMaster on the same machine. You'll need:

• A video card with dual video output
• A 20–24" LCD/LED monitor with HDMI (around $150)
• For video fixation: a monitor with built-in speakers, or a 1080p model that carries audio over HDMI

Yes — but be aware of the relationship between monitor size and patient distance. With unusually small monitors and short exam-lane distances, the 20/400 line may not display correctly. If you already own a 15" or 17" CRT/LCD, you'll be fine. If you're starting fresh, we recommend a 20–24" LED/LCD with HDMI or DVI.

Any video clip works. We recommend matching the clip's aspect ratio to your screen for the best appearance.

Yes. Any standard Windows wireless keyboard or wireless numeric keypad works. We also supply a USB foot pedal that toggles the pediatric video fixation hands-free.

Yes. A refurbished all-in-one computer (Dell Optiplex AIO models 2330, 2320, or 9010) from the Dell Outlet is often under $350. Mount it on the wall either directly in front of the patient, or behind the patient with a mirror.

Yes. AcuityMaster meets ANSI Z80.21 (luminance 80–320 cd/m²), ISO 8596 (optotype contrast ≤15% of background), and standard color temperature requirements (2500K–7000K). All current monitors fall within these ranges.
