Our Take

Best understood as a 4K UHD Smart TV that occurs to employ a projector because of its display, the LG CineBeam HU70LA is targeted more at everyday consumers than traditional videophiles and dark-room home entertainment enthusiasts. The latter groups will see better overall display quality with other products in this price class, however the HU70LA offers a satisfying image for ambient light and lives up to its promise of behaving like a huge screen Smart TV that’s also compact enough to be portable.

You can reasonably think about the $1,799 LG CineBeam HU70LA as a projector which includes a TV tuner, LG smart TV interface, LG ThinQ voice commands and Google Assistant. But that means it is sound like it and voice recognition features are some kind of clunky add-ons. Think about it instead as a 4K HDR smart TV that occurs to employ a projector as a display rather than a flat-panel, and you will have a far greater sense of how well integrated TV and projector are and how it is best used-namely, as an easy replacement for a major screen TV.

This isn’t to state that you can’t utilize the HU70LA like any other home entertainment projector. However the HU70LA is targeted more at everyday consumers than serious videophiles or home entertainment enthusiasts, and you will find projectors with overall better image quality for dark-room environments at around the same price. What you’re spending money on here, along with solidly competent LED-based projection, is LG’s complex and tested web-streaming platform and interface borrowed from its tradtional smart TVs. That, in addition to the flexibilty that comes along using its compact, all-in-one package. For home use, for instance, you can arrange it as needed in virtually any room or take it to the backyard for a movie night. LG also suggests it’s suitable for business use in small conference rooms, or as a light-weight 4K projector for road warriors.

With all that at heart, even judged strictly as a projector and ignoring the smart TV platform, the HU70LA offers enough to create it a tantalizing choice. Its LED source of light was created to last the life span of the projector, and image quality-particularly color accuracy-with default settings is sufficient generally in most modes to be highly watchable straight from the box. Several (though not absolutely all) of its color modes offer all of the controls it is advisable to fine tune color accuracy and grayscale.

LG HU70LA Features
The HU70LA is made around an LED source of light specified to last up to 30,000 hours and a 0.47-inch 4K DLP XPR chip with a native 1080p micromirror array that uses the XPR system’s fast-switch pixel-shifting to place a complete 3840 x 2160 pixels on screen. The source of light has four channels, or LEDs, with red, green, blue, and what LG calls dynamic green. According to LG, the dynamic green increases brightness and contrast.

One of the most notable features may be the HU70LA’s method of adjusting HDR tone mapping. Since there is no standard for content to check out, the very best setting-for any projector-depends on the movie you’re watching. Most projectors offer an HDR Brightness control you can transform manually. The HU70LA offers Dynamic Tone Mapping instead, an attribute we first encounterd inside our overview of LG’s CineBeam HU85LA UST projector. It analyzes each frame, adjusts mapping on the fly, and eliminates the necessity for manual adjustment. This feature has a right to be widely imitated if done properly, and editor Rob Sabin found it worked effectively in the much brighter, laser-driven HU85LA. However, I finished up turning it off in the HU70LA after since the mapping tended to result in a significant lack of shadow detail.

Unlike most projectors, the HU70LA doesn’t show any clear color bias with any color preset mode, despite having a black and white scene. Most persons will consider even the brightest mode a lot more than acceptable for everyday viewing. I measured it at 821 ANSI Lumens, which is bright enough to fill a 16:9, 130-inch diagonal, 1.0 gain screen in a dark room, or a 90-inch, 1.3 gain screen in moderate ambient light-even without taking the promised higher perceived brightness for LED projectors into account-a subject I’ll get back to when discussing my brightness measurements. LG’s specs put perceived brightness as equal to a 1,500-lumen lamp-based projector.

Setup is easy. The lens offset is best suited for putting the projector on a table, where in fact the bottom of the image will be roughly at the guts of the lens. It is also suited to inverting in a ceiling mount, if you may desire a mount extension. The 1.25x manual zoom offers overall flexibility for positioning, as the powered focus adds the capability of using the remote to get sharp focus easily while standing at the screen. For a 100-inch image, the throw distance ranges from roughly 8.75 to 11.0 feet. (For the number for your recommended screen size start to see the LG HU70LA projection calculator.)
