The P525UL offers several picture modes and I found the best quality, in terms of color accuracy, to be the sRGB mode. For the screen shots below, the factory default settings were used for SRGB mode except the Lamp mode was set ECO. Since the P525UL includes user adjustments for white balance, gamma and colors temperature so I am sure it could be calibrated to produce a more accurate picture..
Looking at the images on the player above, the first are our test images of color pie charts and skin tones, for the different Preset modes. Next are images of a variety of videos and photos in 4K and HD resolution. Like all our photos, they remain unadjusted for color, so they do not look as good as what the projector produced.
Switching from DLP to 3LCD had a big impact on colors reproduction especially in the brighter picture modes. The P525UL reproduced good reds and very respectable yellows, which is normally a huge challenge single-chip DLP projectors that have relatively low Color Light Output (compared to white light output).
Overall the picture quality for displaying video is very good for this class of projector. While not perfect, the overall color accuracy as very good, with natural looking skin tones, and reasonable image contrast. The P525UL has a dynamic contrast feature than can be turned on or off. However, when turned on it operated much too slow to be of any real benefit for viewing video.
