Performance

To evaluate the projector we are using the Grandview Dynamique DY3 100" ALR screen, which provides a 140° viewing angle and gain of 0.4. It is set in a living room with natural sunlight from the left and ceiling lighting from the right.

We test real world luminance the same way ANSI lumens are measured. This includes a nine-segment white screen across the 100" or 2.75 m² canvas in a dark room where the ambient luminance (it boosts the values of the digital light meter) around the area of the projected image is just under 1 Lux. While the projector's brightness and contrast may be adjusted to see the eight shades of gray in a control image, we test the unit at its default settings. The used measuring device has a variance of 4%, which should be taken into account when considering the final result in lumens. Lastly, as measuring the nine zones is a manual process, some variance is expected, especially with short throw and ultra short throw projectors, as one has to point the measuring device at the light source instead of laying it flat against the wall as with classic projectors.


For the test the brightness is turned all the way up, by selecting "Performance Mode" on the MoGo 2 Pro. This setting comes with a warning that this should not be used for prolonged use and it also cranks the fan up to 100% - as such, this setting is really not something you should be using on a daily basis. In this mode, the XGIMI MoGo 2 Pro clocked in at around 140 Lux before considering any device-specific variances across the surface area of 2.75 square meter, which results in approx 385 ANSI lumens. However XGIMI no longer communicates the brightness of the unit based on ANSI, but instead uses ISO Lumens as a number - more specifically "up to 400 ISO Lumens" for the MoGo 2 Pro. The ratio between ANSI lumens and ISO lumens (ISO21118) is 1:0.8. that is, 1 ANSI lumen = 0.8 ISO lumens. This means that the result of our test is around 310 ISO Lumens, which is roughly around 78% of the advertised maximum. This is in line with the experience we have had with past XGIMI devices where the actual brightness, regardless of standard used, is below what is advertised.

Daytime Performance

As expected, after testing the brightness of the unit, it is not nearly capable enough to provide a functional image during the day with blue skies and diffusing blinds used around 5 PM here in the Pacific Northwest. Less than 400 ANSI lumens / at 310 ISO Lumens is simply not enough at our 100" projection surface. You will need to manually darken the room and move to a smaller projection size at the very least to get something watchable. As such, we will focus on the nighttime element.
