To illustrate how this projector cuts through ambient light, the image below was taken at night with the curtains drawn, shades closed and lights off, followed by one with the overhead lights on – including two lights directly above the screen. These two photos, like all the others showing video and presentation content, we taken in Standard Mode.
Dynamic Mode measured in at 2,988 lumens, but I found color to be a little too green, similar-to-but-not-as-bad as Brightest Mode, and as such should probably only be used in times of desperation.
Standard mode had some pretty awesome color, and I was thrilled it measured in at 2,988 lumens – that’s really good for a color mode providing good color on a DLP projector, especially when its advertised lumens are 3,200. We’re talking a difference of 212 lumens less than claim for good color – that’s less than 7% below claim. I’m very happy with this measurement.
sRGB mode was the next, at 2,221 lumens and a noticeably warmer color. Movie mode was also quite warm, and measured in at only 1,927 lumens. Again, a little too warm, especially in skin tones, but not bad overall.
Brightest Mode in ECO brightness comes in at 2,273 lumens, which is pretty bright for ECO, and plenty bright to combat some moderate ambient light scenarios, but wouldn’t be my first choice due to the poor color quality. If you want brightness, and good color quality, stick with Standard.
The ViewSonic LS620X is a fixed focal length projector, so to adjust image size the projector’s position needs to be physically adjusted toward or away from the screen. Image sizes between 60 and 150 inches are possible with a throw distance between 2.4 and 6.1 feet. Keep in mind that, as the projected area gets larger, image brightness will be reduced – so if ambient light is your concern, keeping the image as small as practical will best combat the effects of lighting.
