+Tim Z Hi Tim, I'm considering doing this for a large outdoor movie projection. My budget is a little lower than the $2600 that two Epson 1960s are. I was considering a Benq MH741. This projector 4000 lumens projector is $899 and has "corner fit" correction like the epson, so it should work the same way, right? Thanks

I built this rig for a recent event (September 15, 2016) and it works I used it for over 6 hours! There are some caveats though... There are omissions in the video and perhaps they aren't entirely necessary, but would have been nice. 1 - Decide on how you can position your projectors on each board. Mine were mounted using the straight edge of the board to keep each one aligned. Position also has to consider the lens' position left and right. 2 - Create a paper template for the projector mounting points. This will make drilling holes way easier. 3 - Drill the corner holes slightly larger than the threaded rod. You need enough play that the boards do not hang when you move them. 4 - The video implied that tweaking the blending of the two projectors was an easy thing to do. It is not. 5 - As the video states, you must have a projector that allows for corner HDMI adjustments. 6 - Turn off remote control on the upper unit as the video stated. Use the wireless remote for the lower unit. 7 - If you do events, determine how far you need to be away from the screen. Once you have this setup you will not want to move it. This thing is a real pain to setup. I used MDF and the threaded rod would easily get hung up when moving the top board/shelf. It does not double the brightness, but it does make enough of a difference that it is worth the hassle. That is all.
@TheRickJames3 жыл бұрын
I was thinking why not invert one of them and use image flip and image shift. That way you could mount them bottom to bottom on a board and rear mount the entire rig using a bracket or something, it would only be slightly bigger than a commercial projector.

Is that because, as with most perception, the relationship between actual brightness and perceived is logarithmic. So a light meter may say something is double brightness but it may only appear 50% brighter

Great set up especially for a basic dual platform for the projectors. For those who argue the technical aspect of getting 10,000 lumens from two 5,000 lumen projector, I say the main point is you are getting a stronger picture for way less than a 10,000 lumen projector cost wise. Wonder what a light meter would read for the two projectors verses just for one?

The lumen meter will just measure double the brightness. It´s your eyes perception which is applying a gamma curve / log scale.

Great work Tim. Nice rig. This is a tried and true method to get more brightness from projection systems and your DIY rig is a very economical approach. Please note however that doubling the number of projectors does not double the lumens. The brightness increases logarithmically, not linearly. So two 5,000 lumen projectors equal something around 8,500 lumens as I recall (perhaps another commenter could do the math for us based on the Inverse-Square Law.) Each projector added brings less of an increase, with greatly diminishing returns beyond 4 projectors.

Thanks for these videos about stacking projectors. I have only just come across the concept of stacking, so this is great information for me. For more stability in the stacking stand, I would suggest that if you installed a second Nut below the Nut that sit under the platform you are adjusting, the second Nut would prevent the first Nut from any movement due to vibration or thermal changes overtime. I used to make aircraft parts and we would use this double Nut method to ensure the Jigs would not lose their tolerance. You will adjust the bottom Nut as demonstrated in this video and then when you have it in the right place you can secure it by tightening the second Nut up against the first, that way the first Nut will remain in the perfect position.

Projector alignment is spot on, but 2 x 5k does not equate to 10k. Stick a meter on it and you will see that you'll only actually get around 7.5k ANSI. Don't take my word for it though, try it yourself.

I'd be interested to see this technique with a couple of polarizing filters for a proper (non-interleaved) 3D projection using the passive glasses that they have in the cinema (as opposed to the expensive shutter glasses used on 3D TVs and 3D projectors). I guess it would depend on getting video that is separable into two synchronised streams and finding a polarizing filter that isn't too dark and doesn't melt in front of the lenses...

If I had a pair of identical projectors mounted on the ceiling together (and I do) I would want to be able to control them independently with their IR remotes, but of course messages from remote will go to both units. It would be interesting to try taking a page from the playbook of polarizing-3d-projector fan (which I am). One could add polarizing filters to the ir sensor of each projector, each at 90 degree angle difference from each other and install one on the output of a remote. In theory turning the remote one way should give commands to just one projector and turning it 90 degrees would send messages to the other. Also since you have two projectors you have two remotes (hopefully). You could put polarizing filters on both remotes (at 90 degree angles) and fun-tack the remotes to a board for convience. If all goes well you could then control each projector with each remote when its tuned right. This is all in theory, but it might be worth a try. I personally have not been motivated to do this since my home theater projectors can be reached just by extending my arm upward. In churces the projectors are mounted considerably higher up. :-)

I would had tryed to mount them with the top one upside down and slide shifted so the lenses comes alinged each other and to reduce the gap between each of them at the minimum ( top to top) projector, almost touching. That way, alignment would make more sense as the light sources would become almost near as a single light souce.
@phineaseandferb765429 жыл бұрын
Actually, based on Disneyland Resort's Disney California Adventure mostknown attraction, World of Color does use this type of projector stacking. The reason why they did it this way is to make a very bright projector (my possible guess to the actual lumens of the professional type projectors are possible at least 20,000 lumens) they used the same way as Tim did in order to projector that vibrant image through the water screen. On my opinion, doubling a single 5,000 lumen projector will not give you a 10,000 lumen projector in total, it is possible that it will only total up to 7,750 lumens or even 8,050 lumens in total.

@MechnoSferatu7 жыл бұрын
I think that this is a great solution. The only caveat that I'd offer is that you are taking a hit to contrast. But the proof is in the projection and I'm sure that when you're using your 2x or 4x rig, the image looks better and better for your application the more of the projectors you turn on. When you're chaining projectors, have you noticed any lag in signal further down the chain? Or is the 4th projector's signal still seemingly in sync with the first one?
@Running12267 жыл бұрын
I used short VGA cables chain them from one projector to the next and did not experience any lag. I did run into problems with weak signal when I try to run long VGA line to the projector.

your geometry is way off, you should get projectors with lens shift and move them closer together. maybe consider 3 legs 2 up front 1 rear and stacking them on the bodies. corner correction should come last. because if you align them right, each time you move them or bump them they DON'T need to be readjusted
