If you’ve not watched the installation of the projector screen, the video is below. But sadly I discovered that the lights in the place are all on a single relay… no local dimming. Undeterred I snooped around, these are LED panels, you would think some sort of PWM or other dimming would be possible, right?
Turns out they implement a crusty old standard called 0-10V. The panels are from Earthronics. OK, so now I need a way to get 0-10V up there on the ceiling, with me on the floor. Interestingly, the standard calls for being either a source or a sink, its kinda fuzzy, you have to know. The power supply is an XZ-LK50B (here). But, the xz-power site is down. Hmm. I’ll assume we are sourcing.
A little googling, and some credit card, and I am the proud owner of a Keilton PPA101S. Sweet. Got ladder, screwdriver, and a desire to muck w/ the lights, which may or may not dim once done.
Today arrived our projector. A 4K Ultra-Short-Throw Laser. With 7000 lumens. Its amazing. Even more amazing, I ordered it Friday, it shipped from Hong Kong, and arrived Monday.
Now, as you might expect from a device intended for the domestic China market, the localisation into traditional Canadian English is a bit spotty. But, its gonna be HDMI-1 in off a Chromecast so that’s not too important.
So, turn it on, install the spandex 150″ screen to the wall. And as I’m about to setup the keystone, what do i see? Its welcoming me? zoom, enhance… The guy in the yellow. “Goodbye Mr. Loser”. Huh. So nice this pre-packaged greeting.
Before you ask, yes, this is *after* changing the interface to English!
But, its an amazing projector. If you are a home buyer, look at the Xiaomi one for 4K (with pixel-shifting but still). If you are a workplace / bright room buyer, go for the Wemax One Pro @ 1080p for the 7000 lumens. Its a great deal for ~ $1500. There’s really nothing else out there with this brightness without getting into $20K + Christie Digital territory.
So, Mr. Loser I maybe, but meetups will be able to progress w/ 150″ of laser goodness.
