Then select S/W upgrade start and confirm. The update process takes 10-20 minutes; do not power off the monitor during the update.

How do I use the waveform/vectorscope function?

Press the F1‑F4 button assigned to waveform or navigate via OSD menu WAVEFORM. Select Waveform type to choose from Waveform, Vectorscope, Waveform YCbCr, etc. Adjust Intensity and Transparency as needed. The waveform displays luminance levels; the vectorscope shows color components.

How do I display markers and safety areas?

Press the MARKER button on the front panel to toggle markers on/off. In OSD Menu > MARKER, select Marker type (e.g., 16:9, 4:3) and Safety Area percentage (e.g., 90%, 93%). Enable Center Marker if needed. Marker Mat darkens outside the marker area, and Marker Color sets line color.

How to adjust color temperature?
