I have been lucky to compare BenQ HT1075 vs Optoma HD141X and I’m ready to share my results. Firstly, I’d like to point out that BenQ HT1075 includes MHL that allows me to connect it to a Roku Stick for streaming Netflix content. Not all projectors have a vertical lens shift, but this one does, so it’s possible to move the image up and down from the center by about 5% of its height. It eases the process of the picture adjustment because I don’t need to move a projector physically.
3D and 2D images are equally of high quality. In addition, I don't see any crosstalk and only see a hint of 3D-related motion artifacts. I tried to use it outdoors at night on a 12 x 20 screen, but it was clear that it was pushing efforts to its limit. I placed it 30 feet away to be able to get that large screen size. Ideally, you want no ambient light at that distance. You may want to look at going with a smaller screen or a unit with higher lumens.
Read more of my reviews if you still choosing, I have done a plenty of both these projectors comparisons versus other models where I tried to include more practical experience rather than obvious data from a chart.
Before making a purchase, take a note that Optoma HD141X provides an energy saving feature, in a standby mode, it consumes just 0.5 Watts. Also pay attention to BenQ HT1075 audio out that feeds sound to a larger sound system, of course, if you use MHL source.
BenQ HT1075 has smaller keystone correction manual in comparison to Optoma HD141X (- 30 versus - 40 degrees), while the last one doesn’t have USB (Type mini-B) and RS232 (DB-9pin).
In contrast, BenQ HT1075 has more powerful lamp type (240 vs 190 W), but Optoma HD141X has twice higher contrast ratio (20000:1 vs 10000:1).
