You've got a gorgeous ultra-short throw projector and a wall that's 40mm off from where the image needs to land. A universal bracket won't solve that. This one will.
The PJ-WMK-304 was built specifically for ViewSonic's ultra-short throw range. No adapter plates, no 'will it fit' guessing. You bolt it on, nudge the tilt, roll, and yaw until the picture sits dead-centre, and you're done.
The arm slides from 365mm to 635mm, so you can tuck the projector close for a 100-inch image or pull it out a touch for a bigger throw. The steel plate (440 × 210mm) grips the wall properly, and the whole thing holds up to 25kg without a wobble. White finish means it disappears into an office wall or a classroom.
Hardware and the installation guide come in the box. Read the guide first — the screw pattern is specific to your model, and that saves you a trip back to the shop.
