Overall, the Picture Quality is pretty good. But, as Eric, our calibrator points out on the calibration page, there are some noteworthy limitations if you need to calibrate to get extremely accurate color.
Fortunately picture quality is more than good enough for typical business or education use, and most digital signage applications, not to mention houses of worship, and entertainment venues. There are, however, certainly uses – such as dealing with accurate reproduction of photography or movies. Even some digital signage applications might call for really accurate color.
The preset picture modes vary a good deal. The brightest mode, as usual, leaves a lot to be desired. All the others are different, but are pretty good. None, however, would make for really good home theater use, out of the box with no adjustments – the modes are just not accurate enough. Calibrated though… it can be a bright, 4K UHD home entertainment projector, although still not as good as most dedicated home theater projectors.
Technically, the S718QL is a commercial projector (business, education, other non-home uses, including Digital Signage). However, this is a 4K UHD projector with a laser light engine and is very bright, so it has drawn a lot of interest from the home theater crowd. As such, we will be later publishing a an addendum of this projector's review that is more geared toward home enthusiasts.
