Buy Dell S718QL on Amazon: http://geni.us/qjrT

 

Ever seen a projector that made you think "Wow, I'll never buy a TV again"? This 4K laser projector is as vivid and bright as any TV- but bigger!

tmw you think "oh cool, a 90's grain filter on the intro, because it's about the 90's!", but it's not a filter.. It's YouTube at 360p!

 

Gotta wait a couple minutes for this to process :)

Cheaper then the 6000 dollar 4k laser projector of dell  , it cost only 1700 us dollars.

1) The single blue laser does not produce coloured light with a colour wheel. It is a laser+phosphor system. The phosphor produces white light when hit by a laser. This white light then passes through the colour wheel (or dichroic mirrors for most projectors) to produce the 3 colours.

This means it loses just as much light as a regular lamp projectors does because it still needs to produce pure white light and then filter it.

 

2) The laser is extremely inefficient, combined with the fact that the laser-phosphor light conversion process is also not anywhere near 100% efficient, this causes the projector to still use a ton of power, 500W actually, just as much as a regular lamp projector, or even more in some cases. The lasers get extremely hot too.

 

3) It is not at all like OLED, it is not possible to turn individual pixels off. It is just a single cluster of lasers producing a single point of white light, like a regular projector. The black levels are not any different because it is using laser instead of bulb.

 

4) It's a projector, and still has the same primary drawback as any other projector. The contrast gets worse the more ambient light there is because it needs to be projected onto a white background.

Everything fine with the review, but I am curious about one thing.

Metric system is being used in Canada, right? Then WHY is Linus speaking about 15" of  distance between wall and the projector. I know that some measurements like screen diagonal are expressed in inches in most cases, but please, for standard measurements metric system should be used. Linus is not from the us US and LMG is Canadian company so please use metric system or both metric and imperial.

I love the new laser and I love the channel.

 

However I should point out an mistake in the video dell is not the first far from it.

 

I don't think the dell is the first

Lg has had several ultrashort laser projectors

 

Xiomi ultrashort laser projector was the first cinemagrade ultrashort and it is still cheaper then the Dell matching 5000 lumen.

The only con being its chinese menu.

 

Great technology the future is bright

This "review" is such crap. No, "laser" projectors don't have a brightness advantage. Most lamp-based projectors don't use a color wheel, it's use is MUCH more prevalent in "laser" units. No, "laser" projectors aren't quieter, it's the other way around - for a given brightness level, lamp-based projectors are quieter.
