New Epson 130" Laser Projector


Guest EZYHD

Recommended Posts

A laser display up to 130"  the image is supposed to be as good as a standard LCD, resolution is 1080p, contrast is awesome @ 2,500,000:1and the unit can placed right next to a wall for convenience, the laser could last 10 years!. This should put a cat amongst the pigeons once released at the suggested price of US$3000, only time will tell once reviewed can see initial info here.

Don't fall into the trap of believing manufacturers contrast numbers, they are almost always totally incorrect and or misleading as in this case.

What Epson is offering is an LG Hecto type product, single chip DLP with laser light source and ultra short throw lens. Being DLP it will only have a real world contrast ratio of about 2000:1 not 2,5000,000:1 as advertised.

The 2,5000,000 number is obtained by doing a full on - full off test, in that situation the laser will switch off completely for the full off test just like a cheap LED LCD. As soon as even one pixel needs to be on (an actual picture is being displayed) the laser will switch on and native contrast is dictated by the DLP chip which provides only 1000 to 2000:1.

Since the native contrast is very poor and the projector is very bright the black level with an actual picture being displayed will be very high.

 

Just as with any front projection system, contrast and black level will be VERY poor unless the room is dark.

Well there ya go. So the reviews will be interesting then. I guess a person who wants a Pj on a table and not technically minded will fork out US$3K.

Is that a 1,250,000% exagerration? That's quite out there.

We might not even see this model here in Australia anyway. We don't get every model.

With a laser source (depending on the implementation) the entendue is far superior to a lamp, this does enable the optical system to acheive much greater contrast. So I would expect improvement over a lamp system.

When did Epson switch to DLP??

Exactly so DH ; it just uses standard epson 3LCD chipsets:winky: So on/off contrast wont be as bad as a dlp thankfully ;  Looks to have hdmi 2.0 inputs though so can take UHD signals including Netflix or whatever your roku can manage :thumb:

I'd imagine it would use the reflective LCD used in the LS10500 rather than transmissive LCD used in the TW9xxx

Good point for sure ; when they didn't mention any e shift type 4k wobulation like the 10500 I just went with the cheap option ie  ""The light engine is built around three 3LCD Full HD 1920x1200 resolution chips""

That would only be the case if a scanning laser system was used, which would be very expensive to implement and as far as I know has not being done by any manufacturer at this time. Its the sort of thing we may see in high end projectors at some point.

 

Existing laser light sources are basically a lamp with reflector replacement, the lasers light output has to be scattered over the imaging chip by a diffuser which destroys the lights coherence.

 

Using a 3 chip LCD imaging system will still result in poor contrast, you might get 6000:1 if you are lucky which a LONG why short of the claim.

 

To put things in perspective, JVC make a "true" 4K projector with a laser light source that sells for around $40K (the Z1). JVC's DILA LCoS technology normally has 5 times the contrast ratio of the nearest competitor (Sony SXRD), and about 10 times that of LCD based projectors, yet this expensive laser based projector has much worse native contrast then JVC's much cheaper E-shift  lamp based projectors. This should be no fault of the laser light source, its almost certainly due to the difficulty in maintaining high contrast with an imaging chip with many more pixels.

The point is the laser light source does not help contrast.

 

I have seen a data grade Epson projector that is very similar to this 'new" one. It was lamp based and was intended to be mounted above or below the screen very close, front of lens about  500mm from the screen from memory. It seemed to be using LCD chips as screen door was quite noticeable but it worked surprising well and screen geometry was amazing good for such an arrangement. They can do astonishing things with lenses these days.

 

Anyway this Epson is a competitor to LG's Hecro, its not a new concept and has been around for years.
