HOME > Shootout: Epson HC 2150 vs Optoma HD39Darbee
November 6, 2017,
The Epson Home Cinema 2150 and Optoma HD39Darbee--both selling for $899--are one step up in price from the most basic entry-level home theater projectors. In both cases, the extra money buys video processing features you won't find on lesser models, a longer range 1.6x zoom lens, and a modest vertical lens shift that makes installation a bit easier.
One of the more important differences between the two projectors is the advanced video processing each includes. Only the Epson HC 2150 offers frame interpolation for smoother motion and judder reduction in camera panning sequences, while only the HD39Darbee includes DarbeeVision for enhancing detail, contrast, and a sense of depth.
Also important are differences in brightness and contrast, although both are the opposite of what you would expect from the specs. The HD39Darbee has the higher brightness rating, at 3,500 ANSI lumens, compared with 2,500 lumens for the HC 2150. However, we measured both at essentially the same brightness in their brightest modes, and the HC 2150 is brighter in the modes you're most likely to use. That translates to the HC 2150 delivering more saturated color in higher levels of ambient light and gives it the advantage in a brightly lit room.
The story for contrast follows the same pattern with the roles reversed. Though the HC 2150 has the higher contrast rating, the HD39Darbee actually has visibly better contrast--at least for 2D. In the dark or in dim lighting, that gives it more vibrant color and a greater sense of depth.
With 3D film and video, the HC 2150 delivers both higher brightness and better contrast, but unless you watch 3D a lot, that won't matter as much. In any case, which of these projectors is the better choice for you depends a lot on the ambient light level you'll be using it in.

Key Differences and Similarities
The Technologies: 3LCD vs. DLP. As with any comparison between a three-chip 3LCD projector and a single-chip DLP projector, many of the differences between them come from the technology each uses. In this price range, for example, DLP models like the HD39Darbee usually offer better contrast than LCD models like the HC 2150. That holds true for these two projectors and is a key advantage in a dark room for the HD39Darbee.
Two less important differences in this case are rainbow artifacts and the need for a dust filter. The HD39Darbee's DLP engine, which updates colors sequentially, can produce rainbow artifacts. The HC 2150 doesn't because its three chips display all primary colors in unison. Though rainbows can be a problem on some DLP models, the HD39Darbee produces these artifacts so infrequently that they aren't an issue.
An equally small disadvantage for the HC 2150 is its dust filter, which needs to be cleaned and occasionally changed to avoid dust build up and overheating. That's standard for 3LCD models. The HD39Darbee doesn't need a dust filter.
Lenses. Both of these projectors have a 1.6x optical zoom lens. The throw ratio ranges are almost identical. For any desired image size, you can position the HC 2150 very slightly closer to the screen but the difference isn't enough to matter in most cases. For example, to get a 120" diagonal image, the throw range for the HC 2150 is about 11.5 to 18.75 feet, compared with roughly 12 to 19.5 feet for the HD39Darbee.
3D Video. The HC 2150 offers Full 3D support with RF glasses. The HD39Darbee supports DLP-Link glasses as shipped, and includes a VESA 3D sync port to let you connect a $39 optional external emitter or third party emitter for RF glasses. As is standard, it can work with only one type of glasses at a time.
Connections. Both projectors offer two HDMI ports with MHL on one port. The HC 2150 includes three additional connection choices: A VGA port, a USB Type A port for reading files directly from a USB memory, and built-in Wi-Fi.
Total Cost of Ownership. Although the MSRP for these two projectors is the same, the HC 2150 may cost less over its lifetime depending on the number of hours you plan to use it. Replacement lamps cost an extraordinarily low $49. The HD39Darbee's lamp is $229, but the original may last long enough that you would never have to buy one.
Lamp life in the highest power mode is 4,500 hours for the HC 2150 compared with 4000 hours for the HD39Darbee. In Eco mode, however, the HC 2150's lamp rating is 7,500 hours, compared with 10,000 hours for the HD39Darbee in Eco mode and 15,000 hours in Dynamic Black mode. Dynamic Black works like an auto iris to make dark scenes darker, while also lowering power use and extending lamp life.
Keep in mind that the brightness for both projectors varies with the lamp power mode and color mode, so you need to consider which modes you're likely to use before you can project your long term costs.
Eco modes. Both the HC 2150 and HD39Darbee Eco modes are just under 70% as bright as their brightest power modes.
Zoom lens light loss. The HC 2150's lens curtails hardly any light at the telephoto end of the range compared with the wide angle position. The 8% loss of brightness is far less than with most 1.6x zoom lenses and little enough that you don't have to consider it when choosing how far to position the projector from the screen.
The same is not true for the HD39Darbee's 1.6x zoom lens, which curtails light by 33% at the telephoto end compared with the wide angle position. For maximum brightness, you'll want to position it as close to the screen as possible for the image size.
Brightness uniformity. The HC 2150 delivers noticeably better brightness uniformity than the HD39Darbee, at 83% compared with 69%. The variation in brightness is easy to see on the HD39Darbee with a Word document, for example, but hard to see with the HC 2150. Fortunately, this isn't a serious problem for the HD39Darbee with film or video. The human eye tends to accept the brightness variation as part of the original scene rather than see it as a flaw in the projected image.
Rainbow artifacts. Projectors like the HC 2150, which use three chips and show all primary colors at once, don't produce rainbow artifacts. Single-chip DLP projectors can because they show colors in sequence. However, the HD39Darbee shows these artifacts so infrequently that it is hard to believe that anyone would find them troublesome.
Onboard audio. Both the HC 2150 and HD39Darbee include 10-watt mono speakers, and both offer similar volume and audio quality. At 7.7 pounds for the HC 2150 and 6.2 pounds for the HD39Darbee, either is light enough to take to the backyard for a movie night and both can put out enough volume for a small group without needing an external audio system.
Input lag. We measured the input lag for the HC 2150 at 28 ms. with Frame Interpolation off, 70 ms. with FI at Low, and 98 ms. at Normal and High. The Fine and Fast settings make no difference. The HD39Darbee varied from 33 to 36 ms. depending on the color mode and setting. Both projectors have an acceptably small lag for most moderately serious gamers, though the HC 2150 at its fastest has a slight edge.
Fan Noise. The fans on both the HC 2150 and the HD39Darbee are loud enough in their high power modes so you can hear them easily from eight or ten feet away during quiet moments in a movie. The Eco modes for both are significantly quieter. Unless you're particularly sensitive to fan noise, or are sitting just two or three feet away, you're unlikely to notice either during quiet moments.
The Epson Home Cinema 2150 and Optoma HD39Darbee both offer excellent image quality and performance for $899. Both are solid choices for either an inexpensive home theater projector for permanent installation or a portable projector you can set up for special occasions. However, there are some key differences between them that will make one or the other the better choice depending on your intended usage.
If Full 3D support is an important consideration, the Epson HC 2150 is the obvious pick; its two 3D color modes deliver brighter and higher contrast 3D pictures than you get with the HD39Darbee.
If you don't consider 3D important, your best choice will be based on the ambient light level in the room where you plan to use the projector.
In dark or dim lighting, the Optoma HD39Darbee delivers more saturated color, higher contrast, and a better sense of depth, plus a crisper, more detailed image thanks to DarbeeVision.
In a brightly lit family room or living room, the Epson HC 2150's higher brightness translates to more saturated color and a better sense of depth. Its Frame Interpolation also helps to enhance the live-action look of live and recorded video.
