Measured lumens at 3476. (Per Viewsonic Spec Sheet: Recommended for DICOM format files in simulation mode.) This mode is specifically designed for having the right contrast, etc. to be used for viewing medical images such as X-rays, MRIs, CAT-scans, and so on.
DICOM is not considered good enough for reproducing such scans for diagnostic purposes, as it is expected to less than perfectly reproduce the images, but DICOM is close enough to be used for education - training doctors, nurses and technicians, including presentations at medical conferences. This is an exceptionally low cost projector to be featuring DICOM, which until just a few years ago was rarely found on projectors under $3000.
