They are nearly identical except that the zh is 2 pounds heavier and has a digital zoom. (It can’t have an optical zoom since both models have a short-throw lens). Probably the zh is better for football, since it has the zoom.
Sorry, there was a problem. Please try again later.I have the gt1090hdr. It is an excellent short-throw projector but short-throw projectors do not have the zoom capability, either optical or digital. The zh406st is also short-throw but with 4K resolution. If you need the zoom feature you will need to look at the long-throw models.
Sorry, there was a problem. Please try again later.They're the same projector: The gt1090 was just a special item for big box stores. Zoom effect on both will be digitsl. There is one fixed specialized lens for the short throw that has to be adjusted manually to the projector placement distance.
