I have been running three 4k projectors aligned to one image. Near perfect alignment for sharpness and added brightness. My screen is a 500 dollar fixed frame silver screen with a 1.5gain and is silver for better contrast.
My mounts are hanging shelves, carabiner’s, shims and hot glue. The hot glue is meant to keep the projectors from sliding on the wire shelves. The shims are to make the projectors are centered to the screen as much as possible. I adjusted the keystone at the point.
I have to adjust the projectors every few weeks to align again.
All projectors are 4k. One is laser dlp, one is bulb dlp, and one is bulb 3lcd.
My phone does not pickup the colors as accurate as I’d like. But you can see the sharpeness. Also doesn’t pick up the brightness I am seeing in person.
It is a ghetto projector mount, but has held up for two years.
So steel man the case to me why this would be better than a 1500 dollar OLED tv that I can just flip on and wall mount and be done with convenience and beauty and no wires showing?
65inch vs 110inch. 77inch oled is 2000+ dollars 85inch is 3000. All this is under 3000. For projectors and fixed screen. I have an oled and stopped watching once I got this. The immersion is real.
A 100 inch tv is now around 3000, 110 inch tv is like 15,000 dollars. The 3000 dollar 100inch tcl is not great either. It was released now but is not even mini led. Also the smaller size of the same model is mini led. Once mini led or better yet micro led is 3000 for 100inch, I will make the switch.
but see your not getting to the core of the why for a normal person like me who couldn’t careless to setup one for 100+ inch viewing let alone 3 and perfectly align them on proper mounts they wont fall off of during an earthquake
You understimate me and the normal persons laziness. i just want a screen that I plug a cord in and voila. No alignments. No hassles. No worry about it falling off a jank cage above my head. Look im basically novasty at this point. Things that are uber normal and time saving are my thing now but this is cool to say the least. I guess if someone’s into this it could be a solid blueprint. Do you have any recommended mounts? Im asking for others not myself
So I dont have proper mounts. But I am just using 5 dollar ceiling wire shelving I had around. Hot glued them to the mount to not move when people walk around upstairs, And have heavy duty hooks in the ceiling studs.
I have a projector and they have been my main media “TV” for the past 18 years. I currently have a “real 4K” one, as I did not want any of that upscaling nonsense with the jittery screen. I am sensitive to that sort of thing as it is and can barely stand some DLPs. I love projectors though, and for a while I was running a 223" screen that translated to a literal 16ft wide x 9ft tall. I thought: Hey, aspect ratio of DVDs is 16:9 for widescreen so why not just multiply that out into feet and that’s my screen? lol. Projectors are great in a lot of situations.
Never thought about doing multiple for the same image though as a way to increase brightness. Never even heard of the concept before. I have heard of people using 4 of them and aligning them so that you have a giant screen of 1 image across all 4 projectors before, but this way you are doing it is an entirely new concept.
How much brightness do you actually get from this? Do you think the increase is really worth 3x the cost, a ton more power and heat output, and the maintenance of the bulbs and all that?
Well turning one on and then another has a noticeable addition of brightness (light) that my eyes see. Going to a third is even better.
I looked up on it and people have said if you have two identical model that you would see double brightness. I ended up buying 4 over 5 years and only started using them in this way 2 years ago.
Prior to that my theater consisted of three 65inch tvs side by side for a panoramic kind of setup. But it started with wanting a bigger image and looking that 100inch tvs were just out of my price range.
I bought a Epson UHD projector from 2019 and it looked good. Then saw a sale on a 3000 dollar laser one for 1000 and bought that. The other one I bought last summer and it is benq. So I have a optoma laser (uhz50), benq (tk700), epson (3800 UHD).
Honestly the faux (pixel shifting 4k is not bad. It is really 3840 x 2160 pixel. It is not fake 4k like some are. Which accept a 4k input but native resolution is 1080p or lower. As I have 3 different model and brands the brightness is not really doubled or tripled. It is not 1:1. My laser is dimmer than the two bulb ones.
Three cheap ones arent really 4k, I would say anything over 1000 is not cheap, but a super expensive one still doesnt come near the brightness of 3 sub 2000 dollar ones. I have spent 1200 on all my projector buying them refurbished, on a super sale or used. The most expensive one I have goes for 3000 new. Bought it on a really good sale for 1400. A true 4k or non pixel shifting still lacks brightness. And at that point you are looking at 6000+ dollars.
Your thinking too small. 100 or bust. 110 is god tier for me. If I ever move into a house that can support 140 inch. I will buy a new screen and still have my projectors.
see what I mean?
