What is the Epson EH-LS10000?

The EH-LS10000 is Epson’s most exciting projector for years. And while its £6,000 asking price doesn’t deliver a native 4K resolution such as Sony’s VPL-VW300ES, it does get you Epson’s Reflective LCD and new solid-state dual-laser technologies. A combination that has the potential to be a match made in home-cinema heaven.


Epson EH-LS10000 – Design and Features

Aside from Sim2’s Ferrari-resembling Lumis models, the LS10000 is one of the best-looking projectors we’ve laid eyes on. Admittedly, it’s huge: weighing 20kg, it covers even more table space than its JVC DLA-X700R and Sony VW300ES rivals. But it wears this hugeness exceptionally well thanks to its sculpted curves, the sleek matte-black finish, and the gleaming ring around the large, centrally mounted lens.

Connections are found on its rear, under a detachable panel, and rate as more than respectable by projector standards. They include a couple of HDMIs, two 12V triggers, plus RS232 and Ethernet LAN support for control system integration.

The HDMIs are interesting. For although the projector carries only native Full HD LCD chips, one of the HDMIs supports the new HDCP 2.2 4K-friendly anti-piracy system. Both support 4K playback at 60fps – not just 30fps.

So why bother to take in 4K sources – which are instantly reduced to HD for their run through the projector’s image processing – when your LCD panels are only HD? Because the LS10000 claims to deliver a 2,160-line output image, achieved by doubling its frame rate and shifting the second version of each frame half a pixel across and up from the original frame.

This approach is reminiscent of the e-Shift 4K system JVC uses on its projectors to deliver a 4K effect despite the fact that its D-ILA chips are actually only HD. JVC made its system work well on the X700R, so hopefully the LS10000 will also end up delivering pictures that look more "pixel dense" than those you’d get from a straight HD projector.

At the same time we’re not expecting the LS10000’s "4K" images to deliver the same detail and clarity you get with Sony’s true 4K VW300ES. Obviously this is something we’ll be looking closely at in the performance part of the review.

The LS10000's key selling point is its use of laser technology to produce its pictures. It creates its images by firing a blue laser along two different optical paths: one delivering blue after passing through an optical diffuser; the other generating first yellow by bouncing off a phosphor wheel, and then red and green from the yellow via a dichroic mirror.

Opting for laser is worthwhile for a number of reasons. First it does away with the age-old problem of limited bulb lifespans. Where a typical UHP bulb might last you up to 4,000 hours, the laser-driven light system in the LS10000 is said to last for 30,000 hours.

What’s more, the laser system should prevent image quality dropping off over that 30,000 hours anywhere near as much as you'd expect over the lifespan of a normal bulb. The 30,000 hours equates to 20 years of use, even if you watch your LS1000 for four hours a day.

Using lasers also means you can turn the projector on and off more quickly, without the usual protracted warm up/cool down processes of normal lamp projectors.

The LS10000 adjusts its brightness via the lasers, rather than using a dynamic iris to control light output, which should also lead to quieter running, as well as a potentially greatly expanded contrast ratio. After all, in theory, the projector could just shut off its lasers to achieve a true black colour, and lasers are capable of responding faster than a dynamic iris to changes in image content.

Finally, the use of lasers potentially opens the door to brighter images. Certainly, this aspect of laser technology is causing plenty of excitement on the commercial cinema circuit right now, although the light output of the LS10000 is only quoted as 1,500 Lumens – a figure that's only slightly higher than that of JVC’s DLA projectors. It will be interesting to see how such a figure translates onto our screen, especially since the laser-sourced light will be passing through Epson’s Reflective LCD technology.

First unveiled in 2010, Reflective LCD looked set to represent a huge step forward for LCD as a projector technology, thanks to the way it could deliver a much superior contrast performance to the usual transmissive LCD chipsets. Sadly, though, Epson ultimately bailed on the technology, seemingly because it couldn’t then produce the Reflective LCD systems in sufficient quantities to make them financially viable.

So we’re pleased to see the technology returning to the fray, now with its laser illumination companion in tow.

Aside from not having a native 4K resolution, the specifications offered by the LS10000 are eye-catching. Alongside that 30,000-hour "lamp" life, it claims a contrast ratio of more than a million to one and a colour range that’s able to stretch to both the DCI-P3 and Adobe RGB standards. The P3 colour range raises the prospect of support for the new HDR picture standard starting to hit the AV world, although Epson wasn’t able to confirm that any such compatibility would be possible.

The huge images that projectors can deliver continue to make them the best ways to watch 3D – so long as they do a good job of it, of course. So it’s pleasing to find that the LS10000 not only supports 3D playback, but includes two pairs of active 3D glasses for free.

Epson EH-LS10000 – Setup

Setting up the LS10000 is a joy. The image can have its size, focus and position adjusted from the remote control with exceptional precision, and the 2.1x optical zoom and vertical/horizontal image-shifting functions both offer impressive flexibility.

As you’d expect of such a high-end projector, the LS10000 works hard with its picture settings to cater for pretty much every kind of taste and room situation.

At the most basic level, this finds a series of themed picture presets: Living Room, Cinema, Natural, Dynamic Digital Cinema and Adobe RGB. In addition,you'll also find gamma settings, full-colour and white-balance management (which covers the CMY secondary colours as well as the RGB primaries), a skin-tone adjustment, a series of static settings for the projector’s iris, and a Dynamic Contrast option that adjusts the picture’s luminance in response to a continual assessment of the image content.

Epson also provides a fairly comprehensive suite of controls when it comes to the LS10000’s video-processing tools. These include multiple levels of strength for both a Frame Interpolation "motion smoothing’" circuit and the 4K upscaling system. Alongside the ability to upscale to 4K at five different levels, there’s a separate Detail Enhancement tool that allows you to tweak the range – actually edge enhancement – and strength of the detail processing.

You can also opt to turn off the 4K upscaling if you find the processing distracting.

For setup, we’d recommend you leave the Dynamic Contrast feature off, since it can cause the image to flicker. Also, use the Super Resolution 4K setting on 2 – or 3 at a push – since level one leaves the image looking rather soft, while four and five start to make it look noisy. Turn off the Frame Interpolation system for 24p movie viewing, as it can generate the occasional processing artefact and the projector is good enough with motion in its native state not to need any help here.

There was some debate internally about whether to use the Eco or Medium Power Consumption luminance setting for dark-room viewing.

Some favoured the Eco mode, which runs almost silently and delivers the maximum life for the laser lighting system. Others felt they could live with the reduced lifespan and slightly higher running noise of the Medium setting in return for its slightly punchier images. Given that there seems to be a little crushing of shadow detail in Eco mode, however, we ultimately settled on the Medium mode for most of our viewing.

This is not a "must buy" at this price even with laser. This is simply because at the price it commands there is a more, at least five years let's say, future proof projector. I think at this price point the Sony wins simply because a projector costing this much as of 2016 should unquestionably be a 4K native resolution model. Epson has done something, however, that must be commended and that is to break a laser light engine into a serious home theater projector. Sounds like it's tackled a few of laser's early anomalies too, but why not brighter and quieter? I thought part of laser's lure was much more than life-span meaning lots of light and, though intense, overall less heat? I'm sure I'm just naive here and there must be some hurdles with both or wouldn't Epson ramp it up more? Thus what this product does, and does exceedingly well, is bring a serious laser powered consumer projector to market at what must be considered a high, but not a Dubai oil Sultan price. Great trickled down, as well as up, products will likely follow this groundbreaking product. One thing I would have wished the article addressed is if the new crystal refective LCD panel Epson has introduced here is truly different or just a LCOS panel by a different description. It took JVC quite a few years to make their DILA LCOS the stellar performer it currently is and even so they still lack a 4K consumer panel. It seems this crystal reflective LCD of Epson has arrived really advanced already, but still not in 4K format. This leads me to think its simply LCOS. I hope it isn't because if it's not it's a sure bet this technology has spades of potential ,yet untapped, since by any definition it's relatively an immature new technology. The next, and to me this could by a must buy, is a good bit lower priced Epson laser projector, say $5K or less, with native 4K and improved noise level and light output. That would really be a great projector that I'm sure would also push Sony and JVC to jump into laser to which I imagine we'd see some really fantastic products.
