Looking for the Best Projector For Vj? You’ve come to the right place
Hi my name is Tim I do environmental protection or 3d projection mapping in my church for many large events throughout the year I was looking for a ten thousand lumens projector to improve the visual impact of projected images on the large wall of my church these 10,000 lumens protectors are extremely expensive for my budget and they are very heavy for example Epson powerlite pro costs $15,000 with lens and weights 50 pounds also I did some research with specialized projectors which build yo do projector stacking again they are also very expensive.
Best Projector For Vj
So I came out with this idea using to low cost five thousand lumens LCD projectors with a custom-built reg to do projector stacking. This custom rig allows me to fully adjust top projector prosition which physically align both projector lens as closely as possible before I move on to the digital images alignment step in the end my total cost was under $2,500 and this rig only way 21 pounds i use this setup for two large events.
So far and I am very happy with the results For this setup to work you must have same projectors and both projectors must have corner keystone functionality to build this rig you need 4 1/2-13 thread rods 12 inches 16 1/2-13 x hex nuts 16 half-inch washers yeah one 12 x 48 a black shelf board.
I cut it into two 12 x 20 pieces also the projector mounting screws for your projectors once you have the parts and cut boards to 12 by 20 then claimed both boards together to drill out holes so clamp both boards together with c-clamp then drill these mounting holes at same time.
So they will be aligned you must claim these two boards together and draw them out at the same time in order for these top and bottom pieces aligned now i will show you how to align the projector images using this rig first turn off the remote sensor for the top projector yeah i will change the top projector using the buttons on the projector and I will control the bottom projector using the remote control second turn off auto Keystone ok then move the positions back to 0, 0 yeah make sure.
We repeat the same steps for the bottom projectors also display build in cross hair test pattern yeah then align the center and left and right borders Image Zoom as closely as possible this is a physical lens alignment adjust the zoom then loosen the top knots adjust the bottom nuts until you’re close with alignment.
Yeah tie the top nuts and bottom nuts make sure your images center image alignment should be very close fourth displayed a square pattern like this one with text written on them in corners the test grid pattern image size should be the same size as your projector’s native resolution in my case is 1024 x 768 next make sure you reset your corner.
Keystone positions for both projectors before you start digital images alignment yeah yeah then align the four corners of the test grid pattern once the corners aligned I look at at the sharpness of the text in each corner to dail in the final alignment then you’re done you just build a 10,000 lumens large venues projector for under two thousand five hundred thanks for watching please subscribe to my channel if you liked this video yeah Up.
