• For best edge-blending results, perform the following adjustments.
(1) Black and white adjustment by adjusting R/G/B gain and offset (P101)
(2) Gamma adjustment by fine-tuning gamma (P105)
(3) Color adjustment by using 6-axis color adjustment (P104)
• To reduce distracting colors or differences in brightness where images overlap, try
darkening images by adjusting [Contrast] (or other [Image adjustment] menu settings)
or [Screen color].
