Proper medical displays from big names in the business typically cost many thousands of dollars. They are well tuned, often have nifty features like popup calibrating sensors, and adjustment for ambient lighting. But not everyone wants to spend $5,000 on a screen.
PerfectLum is a piece of software from QUBYX, a company out of Nice, France, that through calibration effectively turns a high end consumer monitor into a perfectly compliant medical display. Not that many of the available displays on the market are compatible, but the FDA just cleared the $1400 Dell 30 inch UltraSharp U3011 to be a proper medical display when used with PerfectLum 3.0 DICOM calibration software. It features a resolution of 2560×1600 pixels, a typical brightness of 370 cd/m2 and IPS (in-plane switching) panel technology.
