Supporting 1920x1080 resolution
… in the first bullet point is deceptive as heck.
Actually, this is a lowly 800 x 480 resolution projector. yes, it acknowledges that over on the specs tab. That only means you can feed it with a 1920 x 1080 signal.
Remember that crappy little potable LCD-DVD player you had? That likely displayed this resolution on a 7-8 inch screen? This projector spreads that low resolution across a wall.
“RCA” is now a shill brand name, licensed out to the highest bidder. RCA, the company that made electronics is long gone.
So don’t be expecting a rich video experience.
