Hey here's a comment that's actually relevant to the video! Laser projectors are amazing. They're slowly being rolled out at the university I work for and they require virtually no maintenance, the image is bright and they also effectively remove the potential for timing errors between them and the control equipment that the end user will operate. Not to mention of course the instant on and off is super helpful when you're trying to troubleshoot a professors laptop connection in the middle of their class.

You forgot to mention that laser projectors are closed systems so the cooling doesn't suck in the same amount of dust and particles, prolonging the lifetime. However, this means that changing it will be much more expensive than the separate conventional bulbs we have today, should you need to do so. They also emit less heat and can be used in any angle. Regular projectors need to be told what direction they're hung and often switch to a portrait bulb in case you want to use them on the side. The high end units we use in the rental business start somewhere around $20.000,- with a default lens kit. Then you want to add more lenses, brackets, flights and infrastructure. 😎
simplified but concise description, good job!

You have a better control on your colors with three seperate monochromatic light sources (unique wave lenght). lasers are also coherent sources (a simple wave, so not multiple phases at the same time), we can create inteference with two beam that come only from the same laser (it can't work with two laser, even if they produce the same wave lenght: waves are not perfect). So for laser projectors, no intefrence are created. A fun fact with interference and laser, we can do holography : recording the 3D perspective of an object by recording with a photographic plate the interference between two beam (one reflect on the object and the other come directly from the source) with one laser, and reconstruct the object with only one beam.
I do see this becoming more consumer pretty soon, I have had chance to play with the Epson projectors (perks of working there) and the contrast ratio is fantastic, also yes the laser life is pretty accurate.

Hi, I'm from the future, some entry level chinese models can now be found at around 500$
Previous company I worked for produced laser projectors, some almost the size of a small car (without about the same cost). The company I NOW work for buys these projectors and uses them for Air Force training domes.
Those kinds of different used technology types of projectors are amezing.
You've seen all the warning that come with laser pens about looking into the beam. This makes me wonder, do laser projectors have the same dangers. If your laser projector is set up in your living room and your kid catches a faceful of HD glory as he walks between it and the wall, are his eyes going to literally get burnt out of his sockets?
you guys should do a quickie on contrast ratio in projectors.
Corporate was suggesting NEC 8k laser projectors for us this year. The way they were set up was basically a single chip DLP projector with a color wheel. They were still ridiculously expensive, we could have bought two halogen lamp projectors for the price of one.
I use a pair of Panasonic RZ770 7k laser projector at work. They are so much better than the lamp-based counterparts (DZ770). I absolutely love them. They use the same interchangeable lenses as all the Panasonic 1-chip projectors use. If you work in AV you should definitely check them out if you haven't already!
So here's a question. Say I am pointing my laser beamer at a white wall and I have it turned on for about 3 - 4 hours every night. Will the laser have any long term effect on the paint of my wall? Will I notice more wear when compared to a normal beamer? How long will it take for the laser beamer to have a visible effect on the paint on my walls? This problem would probably be avoided by using on of those projector screens, would I need a special screen for a laser projector however? So maybe more than 1 question but still, if anyone knows the answer I'd love to know.

We got one in one of the classrooms at my work. My understanding is that it cost $20k. 30,000hrs of operating time may sound like a lot, but our instructors often don't turn the projector off when they're done, so we'll see how it goes.

Here we are in 2022, now, and these things can be had for as little as $300, and they can be battery powered and portable, with bluetooth and wireless built in. Wow, what a time to be alive!
The majority of laser projectors (not just in the consumer space) are laser phosphor. It's not cheating. Whether RGB laser or laser phosphor, the the primary colors are combined to make write before getting to the light engine, where they are then separated by a prism the same as in a lamp projector.
Can you do a video on file format conversions (like with avidemux) and how they achieve that?
That joke in the end was hilarious!
That "gtfo" run at the end made me chuckle.
i lost it with Jon running away xD
I am still dying from the ending
His German reference reminded me of the first Be quiet! power supply unboxing he did. Man that was a long time ago.
You can't separate blue light into red and green light, what's happening with the phosphorous (I assume) is that the light is being absorbed and new light is being emitted at different wavelengths.
30000 hours is 10x longer than the bulbs at the cinema I work at.

The other benefit to laser projection is that the contrast is much better!
What about Casio XJ-A252? It is a Laser/led hybrid and I got one in my house (for cheap from an eBay valet seller). Edit: Found out red is produced by LED, blue by laser, and green by blue laser from a phosphor. Still pretty quiet compared to lamp-based projector.
good Information here thanks
Just wondering how about safety? There was review of some pocket size laser projector with laser class 3R.
One of the best features wasn't even mentioned: true blacks. Just like OLEDs in comparision to regular LCDs, the black pixels are actually "off" (or in this case not lit by the lasers), and not just backlit dark pixels, which leads to insane contrasts. If you haven't experienced it yet (and want to ruin every regular cinema forever for yourself) go see some movie in an IMAX Laser 4K theatre. It's like going to the movies for the first time in your life :D
Love the gold shirt Linus
John knows how it is
Do laser projectors also produce the rainbow effect DLP projectors show when you move your eyes?
I did a quick search and found that most laser projectors employ one laser light source and the operation is the same as LCD and DLP projectors. The laser is only better because it is potentially brighter and more efficient light source, similar to the success of LED over lamps

In fairness, I learned that lasers can be a very good all around light source if costs can be reduced, a step from LEDs, as LEDs did on lamps.
what about the new radeon duo? when are ya making a video about that
You didn't mention 'Infinite Focus'. Laser projectors do not require a lens to focus the beams. This allows them to project onto a curved surface without any blurring. I've always wanted to see a rear projection, extremely curved, display using multiple laser projectors (even pico-projectors). One that literally gives you 180 degree field of view. Edit: You also didn't mention that laser projectors use scanning technology. The laser beam scans left to right, and top to bottom of the image just like the electron beams of CRT's do.

Let's not forget the Pico projectors that can fit in your pocket. I imagine what laser technology can do for them: bigger battery life, better brightness, smaller size... What about other applications for this technology: Less heat, more light, better image... I bet we will be seeing very creative uses for this technology.
