Design and Features
The TW9100W is straightforward to set up, thanks to the centrally mounted lens, adjustable feet and shift, zoom and focus controls. Whilst these controls are all manual it shouldn't make any difference, although obviously it precludes the inclusion of a lens memory feature. The TW9100W includes a decent quality lens, which delivers a sharp detailed image, as well as better convergence and blacks, thanks to fewer reflections in the light path. In addition, Epson has included a motorised lens cover that opens and closes when you turn the projector on and off. It's a bit noisy and clunky when it moves in and out of position but it is a nice touch and helps to differentiate the TW9100W from the competition.
All the connections are at the rear of the TW9100W, which is good as we prefer that to the side connections that some projector manufacturers use. The connections are on a par with those found on most of the competition and include two HDMI v1.4a inputs, a component video input with RCA connectors, a composite video with an RCA connector and a VGA connector for a PC. The TW9100W also includes an RS-232C connector for system control and a 12v trigger for controlling an electric screen or an anamorphic lens. Finally, at the rear, there is also an on/off switch and the power socket which uses a standard three pin connector. There is a cover for the connections, although since you need to remove before connecting a device, we're not sure what purpose it really serves.
The TW9100W comes with the standard Epson remote control, which is attractively designed and well made from black plastic. It includes a backlight which is obviously handy in the dark and large buttons that are well laid out and intuitive to use. The remote control itself is comfortable to hold and simple to operate with one hand, which is also appreciated. There are buttons for all the usual controls, as well as dedicated ones for specific functions such as Colour Mode, Aspect (Ratio), RGBCMY (CMS), Auto Iris, Super-res, Frame Interpolation and 2D/3D. There are also dedicated controls for turning on and selecting the inputs and outputs of the WiHD Transmitter.
The TW9100W comes with two pairs of 3D glasses that use the RF standard, are lightweight, comfortable to wear and large enough to fit over regular glasses. There are wide sides which help with blocking out any ambient light and the lenses are suitably neutral in tint, although we would have liked them to be a bit larger to increase the field of view. The glasses can be re-charged via an included USB adapter and the battery can last up to 40 hours when fully charged, although there is 3-minute quick charge option that will get you through a film in an emergency. At the top of the frame there is an on/off switch and the glasses will automatically switch off after a certain period with no 3D signal.
The TW9100W includes a WiHD Transmitter that allows you to remotely connect up to five HDMI devices to the projector. This can be useful if your projector is a long way from your source device, providing a handy alternative to a long HDMI cable and all the issues that entails. This year Epson has added an HDMI output and an optical audio input, along with a USB port for charging the 3D glasses. The adaptor uses a provided power adaptor and is easy to setup - you just connect the HDMI devices to the adaptor, turn it on and then select it in the projector's menu. We found the range to be reasonably wide and we never had any problems with interference, allowing us to watch content through it without any issues. The wireless adaptor can be selected using the WirelessHD button on the remote and as with all the other inputs, it can be individually calibrated.
As the RGB Balance graph above left shows, there is an excess of red at the higher end of the scale and an excess of blue in the middle, whilst green is underpowered across the entire scale. As a result there was some slight discolouration on a stair step test pattern and Delta E’s (errors) that were measuring above our tolerance level of 3. However, the gamma is measuring very close to our target of 2.2 and overall this is a respectable performance for an out-of-the-box setting. Moving on to the colour gamut, as the CIE Chart above right shows the Natural colour mode is actually very impressive for an out-of-the-box setting. All of the colours are within the DeltaE tolerance of 3 for their overall accuracy, with the exception of cyan which is slightly above that. You can see that white is very close to its target of D65, the square in the centre of the triangle. There is some slight under saturation in green and thus cyan, which is composed of that primary, but otherwise this is an excellent out-of-the-box colour performance by the TW9100W.
After adjusting the two point white balance control, we were able to deliver a reference greyscale performance from the TW9100W. As you can see on the graph, the RGB Balance is tracking at 100 for all three primary colours, with the overall errors all less than 3 and in many cases less than 1. The gamma is still tracking very close to our target of 2.2, although if you needed to there is a more detailed control for adjusting the gamma curve at specific IRE points. Ultimately this is an excellent greyscale and gamma performance from the TW9100W and it lays down a firm base on which to build an accurate overall image.
Thanks to the inclusion of a colour management system (CMS) we were able to improve the already excellent colour performance still further. First of all the reference greyscale is represented by the colour temperature of white, which is now hitting D65 exactly. As a result the colour accuracy immediately improved, especially the hue error in cyan and we were left with very little to do. We were able to get the luminance (brightness) of all the colours spot on, which is important because this is the element of colour our eyes are most sensitive to. We were also able to improve the hue accuracy but we struggled to correct the slight under-saturation in green and cyan. The Saturation (colour) control is not independent of the Brightness (luminance) control and as such if we increased the saturation we also increased the brightness. Ultimately we had to compromise and thus chose the accurate luminance performance over improving the accuracy of the colour. The colour errors were the result of this minor under-saturation but it didn't have an adverse effect on the image accuracy and the overall errors were all less than 2 and most less than 1, which is excellent.
The idea behind measuring the CIE tracking is to see how well the projector tracks against target saturation points as the saturation decreases. As the graph above shows, the TW9100W delivered an impressive performance at all the saturation levels. All the colours are tracking close to their targets, with most actually hitting them. As a result colours remained accurate at all saturation levels and there were no tell-tale saturation issues, such as with skin tone, that could affect less consistent projectors. It would seem that Epson have done a fantastic job of delivering accurate colours at all saturation levels with the TW9100W.
Brightness, Black Levels and Dynamic Range
If there's one area where LCD projectors have come on in leaps and bounds over the last few years, it's their perceived black levels. Whilst not at JVC levels, the blacks on the TW9100W were certainly very good and so was the shadow detail. The TW9100W is also capable of producing an excellent contrast ratio, measuring 5,400:1 and thanks to the brightness it delivered an impressive dynamic range. The TW9100W includes an Auto Iris but you really don't need to engage it as the native blacks are more than good enough. You can use the Auto Iris to improve the perceived dynamic range but in reality, all you'll be doing is losing detail as you crush blacks and clip whites. In addition, the Auto Iris wasn't that quiet, so depending on where you sit, you might hear it in action.
In the cadence tests the projector continued to perform flawlessly, correctly detecting the 3:2 (NTSC - USA/Japan) format as well as the 2:2 (PAL - European) format. The projector also had no problems displaying mixed film material with scrolling video text and was able to reproduce the text without any shredding or blurring.
The TW9100W performed equally as well in the tests using high definition content and with the player set to 1080i, it correctly deinterlaced and displayed both the video and film resolution tests and showed excellent scaling and filtering performance as well as good resolution enhancement. With 1080i material the projector had no difficulties in showing video text overlaid on film based material and also handled 24p content without any problems. We used the Dynamic Range High test to ensure the TW9100W was reproducing all the video levels above reference white (235) up to peak white (255), which it was as long as the EPSON Super White control was turned on. The other useful test is Dynamic Range Low which allows you to check that a display is only showing detail down to video level 16 which represents reference black. Once again the TW9100W was showing detail down to 16 but not below it which means it is correctly reproducing black whilst maintaining appropriate shadow detail.
The motion handling on the TW9100W was reasonably good, although this being a LCD projector it will always remain a weakness. We got about 400 lines on the moving resolution test which is what we would expect, so with camera pans you get some smearing and loss of detail. The TW9100W includes Frame Interpolation software which, as the name suggests, attempts to address this inherent weakness in the technology by using interpolation to create better motion handling. The downside of this technology is that it results in motion artefacts that can be far worse than the perceived weakness of the LCD panel and these artefacts are more obvious on a large screen. It also creates the tell-tale 'soap opera' effect, with unnaturally smooth motion that will ruin the look of film based content.
Frame Interpolation, especially the Low setting, can be used with fast paced sports action shot on video but we would recommend turning it off when watching film based content.
Picture Performance - 2D
The one area where the TW9100W is far better than the cheaper Epson models is in terms of black levels. On this projector blacks appear black rather than dark grey and this gives the image a far greater dynamic range. Despite the claimed lumens, it is clear that Epson has sacrificed some brightness to achieve better blacks but this is still a bright projector that can deliver an impressive degree of contrast to the image. The shadow detail is also much better on the TW9100W and it can certainly deliver the goods in a dedicated home cinema or light controlled environment. As with the other models, the TW9100W includes an auto-iris but there really is no need for it as the blacks are already good and the iris doesn't appear to actually make much difference. As with the other Epson models, it is also quite loud, so it is best left off but if you do leave the auto-iris off, the TW9100W is very quiet in ECO mode and had a NC reading of 22dB which is excellent. Whilst we didn't have any problems on this sample, there is always the possibility of dust getting into the light path and creating visible 'blobs', which is an inherent weakness of LCD projector design.
The superior black performance of TW9100W was immediately obvious during the camp raid ending of Zero Dark Thirty and this was in sharp contrast (excuse the pun) to the TW6100 that we reviewed immediately before the TW9100W. The more expensive projector handled the almost black scenes very well, delivering the necessary blacks, shadow detail and bursts of light. The cartoon violence of Gangster Squad was also wonderfully replicated, with bright colours and a wide dynamic range, as if Baz Lurhmann had remade The Untouchables. The digitally captured images in Gangster Squad were reproduced with oodles of detail, whilst the frenetic action was delivered without judder or any excessive smearing. Overall, the TW9100W delivers an excellent 2D image with an accurate greyscale, natural colours, excellent video processing, good blacks and plenty of detail; as such it can certainly hold its own against the competition.
Picture Performance - 3D
The result of this large, bright and largely crosstalk free image is that the 3D pictures produced by the TW9100W were excellent, providing a genuinely immersive and exciting experience. We tried a few recent 3D favourites, including Dredd, Monsters Inc. and The Hobbit and they all looked superb but what really struck us was how bright the images were. It really made us aware of how much impact a bright 3D image can have and thus how important it is. The absence of distracting artefacts like crosstalk is also important and, as a result, the 3D images were both highly immersive and hugely enjoyable, with plenty of depth. The Cinema 3D mode also provided a reasonably accurate preset but there is also the option to calibrate the 3D image if you so wished. It is worth noting that in the 3D modes, the additional brightness is added by using a higher bulb setting and as a result the TW9100W is louder than when in ECO mode.
The TW9100W had no problems with both frame sequential content or side-by-side and both looked excellent. Our only complaint when it came to the 3D performance was that occasionally in fast camera pans there was some judder but this is not uncommon when watching 3D content.

Epson TW9100W (EH-TW9100W) 3-Chip LCD 1080p 3D Projector Review
As we would expect from an Epson projector there are a comprehensive set of calibration controls and as a result we could achieve a reference performance in terms of greyscale and colour gamut. The blacks on the TW9100W were also excellent, especially for a LCD projector, and when combined with the bright images the resulting contrast ratio and dynamic range were impressive. Motion handling was also very good, especially with 24p content and the video processing was excellent. When it came 2D content the TW9100W was a fantastic performer, delivering accurate and detailed images, with good blacks and motion handling. With 3D content it was even more impressive, producing bright and immersive pictures that were free of distracting artefacts like crosstalk. Whilst the Epson EH-TW9100W may not differ much from its predecessor, if it ain't broke why fix it? In fact Epson has fixed a few minor issues from last year with the TW9100W and once you add in the excellent all-round performance, build quality and features, it makes for a hard-to-resist package. Highly Recommended
