InFocus IN78 Projector


Combining DarkChip 3 DLP technology with a bargain price is no easy feat. Does InFocus pull it off?

Although we finished the main review on a negative note, we really can't stress enough just what great value the IN78 is. You'd probably have to spend not far off double its £1,475 asking price to get something substantially better, while in its own...

InFocus IN78


The IN78 looks every bit as enticing from the outside, but its performance has slowly been surpassed

Great-looking package that's easy to set up ; good attention to detail ; strong blacks

Not the stunning colours of the very best ; could be crisper

InFocus IN78 review


Approach the InFocus IN78 with caution. It may look harmless but despite its dinky dimensions and glossy black finish what we might have here is the giant-killer of the home projector world.

Sure, it’s more expensive than the already pretty super IN76, but that cash hasn’t been wasted and it certainly won’t let the family down

InFocus IN78 review


It's expensive - is it worth the price premium?

Excellent DarkChip3 performance ; Easy to set up

Motion not always perfectly crisp ; Slightly noisy at times

Its performance isn't flawless, but it's certainly better than you're likely to get elsewhere at this price

Review: InFocus IN78 projector | Absolute Gadget


Unless you're a bit of a technophile or know your projectors it's unlikely you would have heard of InFocus. Our earlier review of the InFocus IN76 proved they make top quality projectors, and this model, the IN78 is just as great.

The IN78 is a must-have for anyone wanting a high-performing projector that is easy to set up and use; while it may not be cheap it is less expensive than some of the other high-end projectors available costing around eight grand. For six thousand less...

InFocus IN78


Given how preposterously cheap other recent InFocus DLP projectors have been, we guess £2,000 might seem quite a hike for the brand's new IN78.That is until you check out its specification

Superb picture quality, Few picture flaws, Wonderful colour reproduction

Appears expensive

A classic example of getting what you pay for - £2,000 is a lot of money, but this is a lot of projector

The IN78 is an excellent home theatre projector, but it's not much of an improvement over the previous model. Its price tag is also rather high, considering how little has been done to improve the product.

Excellent performance in standard and high definition modes, Attractive design

Too Expensive, Not much of an improvement over the previous model

InFocus Play Big IN78 Projector Review


The IN78 is an incremental update to a very popular projector line that includes the IN72, IN74 and IN76. Incremental upgrades are nice in that they update hardware and make sure that a product line

Excellent color detail ; Nicely-designed backlit remote control ; 3 direct access source/inputs from remote ; Sleek black enclosure ; Handles 1080p/60 and 480i via HDMI (scaling to 720p)

Tough competition at this price ; Mild rainbow effect present during high contrast action sequences ; Didn't pass blacker-than-black ; No lens shift and high fixed offset ; Awkward menu navigation

InFocus IN78


With the PlayBig IN78, InFocus cushions its 1080p no-show with a tweaked version of its popular 720p PlayBig home theatre projectors now featuring Imaging Science Foundation 3C professional calibration support.

Outlook Not only is the PlayBig IN78 a late 720p entry in today's 1080p-crazed market, the pricing of this model is also hard to swallow in our humble opinion. If you don't mind forking out extra for professional calibration and out-of-the-box D65...

Product Specifications

Perfect for the distinguishing videophile, the IN78 is the highest performing single-chip DLP home theater projector. Native 720p wide screen high-definition means it is ideally suited for HDTV, HD DVD, Blu-ray, or even high-definition gaming. The IN78's zero dead pixel guarantee means that your perfect home theater will stay that way. The 1000 video-optimized lumens provided by the IN78's lamp delivers images over twice as bright as most movie theaters. The 3500:1 contrast ratio ensures deep blacks and bright whites. With the InFocus Play Big IN78, movies and gaming have never looked better. The IN78 has inputs for HDMI, M1-DA, DVI, component video, S-video, composite video, and computer cables providing connectivity to virtually any source. The IN78 uses Texas Instruments 720p DarkChip3 DLP technology to ensure crisp, clear images, rich blacks, dark shades, and fine detail. The onboard Pixelworks DNX video-processing technology anticipates motion to dramatically improve the quality of video and deliver clear, natural-looking standard and high definition images. The powerful appeal of the IN78 goes far beyond the magnificent picture it projects onscreen. Its sleek, futuristic, low profile appearance adds a subtle sophistication to any room. With unique swivel base, it's simple to place on any flat surface, or remove the base and mount it directly to the ceiling. The IN78 is snap to set up. With color-coded cables and inputs, it's simple to hook up to HDMI, DVI, component, S-video, composite, and RS232. There is even a screen trigger for motorized screens.
