That sounds likely, so acting like a digital picture frame.
The projector exterior looks like this

HD 504, HD probably meaning the weasel phrase HD compatible for this one
also.
They've used a first generation, discharge lamp type injection moulder
for the casing as there is the protruding section for the removable
cover for the discharge lamp of Epson? earlier projectors, now
irrelevantly protruding below the casing and moulded as one piece now.
Otherwise like the OHP converter to video , large 4x6 inch or so LCD and
large optics to allow for distributed LED lamp source.
I like the,KISS, keystone adjuster, simply pivots a mirror directly by
turning the knob on the case side
