MORE ABOUT Our services

We offer video calibration services for all popular display types, including professional grading monitors, projectors, direct-view LED systems, and televisions. Our video calibration services are top-notch, utilizing quality metering devices, video signal source devices, and the latest calibration software.

Our calibration process ensures proper video signal processing for pixel-based displays, optimizing picture detail by minimizing overscan, introducing appropriate sharpness without creating artifacts, and ensuring natural-looking motion that captures the artistic intent.

For projector calibrations, we conduct picture geometry evaluations and RGB convergence optimization (when applicable.)

Our SDR and HDR picture preset calibration sessions usually take around four hours. We offer flexible scheduling that includes nights and weekends.

We also offer audio calibration services that take a holistic approach to optimize sound quality. We evaluate the room environment, hardware setup, speaker placement, and available room correction technologies to achieve a reference-grade listening experience.
