Brightness & Color Issues

PC Monitors made by Sony often have drifted out of calibration. This can result in poor color balance, excessive brightness, or other issues. These monitors often have an extremely bright picture, sometimes with a green tint. This cannot always be corrected with the OSD controls, and the monitor's firmware settings must be adjusted using WinDAS, Sony's proprietary calibration software.
