Epson Home Cinema 640 3LCD Projector - Review 2022

The Epson Home Cinema 640 3LCD Projector ($359.99) is a solid choice as a abode-entertainment projector if yous're on a tight budget, don't need 3D support, and don't heed having a lower resolution than typical models. Rated at 3,200 lumens, information technology can throw an image that's big plenty to dwarf any similarly priced HDTV, and bright enough stand up upward to ambient light in a family room. Fifty-fifty if you already have a top-quality home-theater projector for watching movies, y'all might desire the 640 equally a second projector that you lot can move from room to room or set up upward in your lawn to watch movies outdoors on a summer night.

The key reason for the 640's low price is its depression 800-past-600 resolution. Like most TVs today, nearly home-entertainment projectors—including the Epson PowerLite Dwelling Cinema 730HD, which is our Editors' Choice upkeep-priced 2D home-entertainment projector, and the Epson PowerLite Habitation Movie theatre 750HD, our top pick for a budget 3D home-entertainment model—evangelize at least 720p (ane,280-by-720) native resolution. And most of those, including the BenQ TH670, offer full HD (1,920-by-ane,080) resolution.

Quite only, the 640'southward 800-by-600 resolution tin can't testify the same level of particular that you'd see with 720p, much less 1080p. But information technology however offers substantially higher resolution than standard-definition idiot box (SDTV), which everyone constitute adequate before HDTV and is still the resolution yous go with not-Hard disk channels.

Basics and Setup

At 3.one by 11.half-dozen by 9 inches (HWD) and five pounds five ounces, the 640 is small and lightweight enough to move from room to room easily, or—if y'all don't take a identify to set information technology up permanently—store information technology abroad when you lot're non using it.

Setup is standard, with transmission focus, but no optical zoom. There is a digital zoom that lets you adjust the paradigm size without moving the projector. However, that's all-time avoided, since a digital zoom tin can innovate artifacts with some images.

Image inputs are all on the dorsum, with ane HDMI port, one VGA port for a PC or component video, and both S-video and composite video ports. In addition, in that location are a USB Blazon A connector for reading files directly from a USB memory key, and a USB Type B connector for connecting to a PC for direct USB brandish. There's also a Wi-Fi icon well-nigh the USB Type A port that suggests you can plug in a Wi-Fi dongle, but according to Epson that's only because the 640 uses the same case as other models that support Wi-Fi. The 640 itself doesn't.

Brightness

Using the Gild of Picture show and Television Engineers (SMPTE) recommendations, 3,200 lumens is bright enough in theater-dark lighting for a 208- to 282-inch paradigm (measured diagonally), assuming a 1.0-gain screen. For moderate ambient light, the size drops to 138 inches.

1 of import issue to keep in mind is that these numbers are the measurements for the 640's total 4:3 native aspect ratio. When you're watching a widescreen, 16:9 movie or Tv set show, the prototype will cover only a portion of the screen. The appropriate sizes for the sixteen:ix image volition exist 191 to 259 inches in theater-nighttime lighting and 127 inches with moderate ambient light. For darker rooms or smaller screen sizes, yous can adapt the 640'southward brightness by switching to Eco manner, choosing one of the lower-brightness preset modes, or both.

Image Quality

The level of paradigm detail with 1080p input is accordingly well-baked for the 640's native resolution, putting it a step up from standard-definition 480p, simply a big footstep downwards from 720p Hard disk. Typically for a model with this resolution, I would as well await to run into the LCD screen-door outcome—with each private pixel outlined by sparse, dark lines. Surprisingly, however, I had to stand as close every bit three anxiety from the 78-inch-wide prototype I used for nearly testing to come across the lines. They simply don't bear witness from a typical viewing altitude of 10 feet or more than.

Encounter How We Test Projectors

Image quality is more than than acceptable otherwise, although information technology falls just barely into the nearly-fantabulous range. I saw a touch of posterization (details irresolute of a sudden where they should change gradually) and a minor loss of shadow detail (details based on shading in dark areas), only simply on specially demanding test clips.

In addition, the contrast ratio was low plenty in my tests in theater-night lighting to notice, but not low enough to be an issue with ambient low-cal. More of import is that color quality was near excellent in my tests, and then was color balance. It also helps that the three-fleck LCD blueprint guarantees that the 640 won't show the rainbow artifacts that about all DLP projectors do. Overall, the prototype quality is comparable to what you lot'd expect from a high-quality SDTV.

Audio and Lag Time

The 640'due south two-watt mono speaker delivers skillful sound quality, with enough volume to fill a small family room or living room. Unfortunately, in that location's no audio-out port. For stereo, better sound quality, or college volume, you'll have to bypass the projector entirely.

The 640'due south lag time is at least arguably good enough for coincidental gamers. I measured it, using a Leo Bodnar Video Bespeak Input Lag Tester, at 45 to 50 milliseconds (ms), depending on the preset color mode. That translates to 2.seven to 3 frames at 60 frames per second, which is non much slower than the fastest projectors nosotros've tested, at 33ms or two frames. However, serious gamers tend to think even a 33ms lag is unacceptable.

Conclusion

For a projector that offers a higher-resolution prototype but is besides reasonably low-priced, consider the Epson 730HD, our pinnacle option for 720p 2D projectors; the Epson 750HD, our preferred budget choice for 720p 3D models; or the DLP-based BenQ TH670, which offers 1080p, but shows occasional rainbow artifacts. If your primary benchmark is cost, however, the Epson Home Cinema 640 3LCD Projector will give you a big, brilliant, highly watchable image for a seductively depression cost.
