Epson Lifestudio Grand Plus projector review: Google Gemini makes a surprising difference

At a glance:

• Epson's Lifestudio Grand Plus (LS970) is a $3,800 ultrashort-throw projector that adds Google Gemini voice control to its home-cinema toolkit, alongside 4,000 lumens of brightness and a 150-inch image.
• The setup process is outdated and fussy — Google Home failed to recognize the device on the reviewer's network, and automatic keystoning struggled on plain walls without a dedicated screen.
• Despite quirks, the projector earned a 7/10 rating for outstanding brightness, vibrant colors, and a built-in 20-watt soundbar that makes it a genuinely capable home-cinema option.

A new era for short-throw projectors

Epson's Lifestudio Grand Plus (LS970) arrives at a time when ultrashort-throw (UST) projectors are gaining ground on traditional long-throw models. UST units sit just inches from the wall or screen, so no one can walk in front of the projection and block the image. That also means all your streaming gear, soundbar, and game console can live right next to the display rather than at the back of the room. At $3,800 the Grand Plus costs more than last year's Lifestudio Grand, but the spec jump is real: the image size grows from 120 inches to 150 inches, and brightness climbs from 3,600 to 4,000 lumens. Those numbers put it in direct conversation with Epson's own long-throw Pro Cinema LS9000, which costs only about $200 more and is easier to configure out of the box.

Google Gemini on a projector — and why it actually works

The headline feature here is Google Gemini baked into the projector. You can talk to it by voice, which turns out to be a genuinely useful interaction model for a home-cinema device. The reviewer tested prompts like "show me the latest thrillers from 2026" and found the projector delivered results perfectly. They also asked Gemini to mute the audio and change the volume, and those commands worked without issue. Kids can even use it for homework help, which adds a practical dimension beyond pure entertainment. Compared with Google Assistant, Gemini feels noticeably more powerful and context-aware on this hardware.

Setting up Google TV on the Grand Plus was mostly straightforward, but the Google Home app did not recognize the projector on the reviewer's network. They had to manually enter their Google account info, and Epson's own support team was able to replicate the problem. That friction is worth noting — a smart-home integration that requires manual pairing undermines the convenience the feature is supposed to deliver.

Setup frustrations and placement quirks

The configuration process is where the Grand Plus loses points. The unit is big, heavy, and picky about placement — it needs to sit roughly a foot away from the wall or screen. The reviewer had to experiment with positioning before the image looked right, and even then the software felt outdated compared with competitors. The Leica Cine Play 1 and Soundcore Nebula P1 auto-keystone instantly, letting you turn them on and walk away. The Grand Plus' automatic keystoning also struggled on a flat white wall in the reviewer's family room, producing a wavy test pattern that persisted after a hard reset. Only when the projector was moved to a windowless testing room with a professional screen did keystoning and sizing adjust correctly. Epson reps told the reviewer this behavior was not normal, but the practical takeaway is clear: the Grand Plus works best paired with a dedicated projector screen.

Placement constraints are tight. The projector can sit only about an inch away for an 80-inch image or roughly 11.2 inches away for the full 150-inch image. The three HDMI ports — one supporting eARC for a soundbar or AV receiver — are tucked into the corner of the unit, and because the projector sits on the floor, reaching them to connect cables is awkward. The power button on the side is also easy to bump accidentally.

Picture quality and how it stacks up

Once the Grand Plus is properly placed, the picture quality is hard to argue with. During HDR10+ testing with skin tones, the reviewer noticed subtleties between faces that lower-contrast projectors like the Soundcore Nebula P1 simply cannot reproduce. Green grass popped in a winter-fence test scene, and sunset sequences showcased the projector's ability to replicate nuanced differences in oranges, reds, and browns. Streaming the apocalyptic road film Sirāt on Hulu at 120 inches, deep reds and browns looked hyperrealistic, and filmmaker mode pushed blacks and reds even richer. The boxing movie Christy on HBO Max played without stuttering or pausing once the initial casting hurdle was cleared.

However, long-throw competitors hold their own. The Epson Pro Cinema LS9000 has a better optical lens and a separate ZX processor for dynamic contrast, with an aperture ranging from f/2 to f/3 versus the Grand Plus' fixed f/1.8. That gives the LS9000 clearer focus across the entire image and darker blacks. The Leica Cine Play 1's blues and purples popped more in games, movies, and shows. The Grand Plus is brighter and clearer overall, but the long-throw models edge it out on color vibrancy and contrast consistency.

Gaming and the built-in soundbar

For gaming, the Grand Plus connected to a laptop at 120 Hz, and the reviewer's current benchmark title Crimson Desert looked smooth and realistic at the massive projected scale. Individual leaves shaking in a forest scene were visible — something that disappears on a 65-inch TV. The sci-fi game Pragmata looked crystal clear at 4K resolution even at 120 inches, with dark battle scenes remaining legible thanks to the strong contrast ratio. A Google Slides presentation tested for a speaking engagement also showed deep blacks on large headlines and text clarity that outclassed several competing home-cinema projectors.

The built-in 20-watt soundbar is a welcome addition. Dolby Atmos worked perfectly during a full watch of the survival thriller Thrash on Netflix, and dark scenes remained visible thanks to the exceptional contrast. The surround experience was not as convincing as the Focal Muso Hekla soundbar the reviewer tested separately, but it was "certainly thunderous." Music playback of Samia's "Bovine Excision" sounded fine but did not rattle the sheetrock the way a Cambridge Audio Evo One would.

Remote and daily usability

The remote echoes the layout of an Amazon Fire TV remote, with four dedicated buttons at the bottom for YouTube, Netflix, Amazon Prime, and free television channels. The back button sits on the lower left, volume controls are on the right, and Epson even added dedicated brightness buttons for quick adjustments. The remote is not backlit and pairs only within 3 to 4 feet of the unit, which limits couch-distance flexibility.

Despite the setup headaches and a few quirks around keystoning and network recognition, the Epson Lifestudio Grand Plus earns its 7/10 by delivering outstanding brightness, vivid colors, and a voice-controlled Gemini experience that genuinely adds value to the home-cinema workflow. For buyers prioritizing short-throw convenience and smart-assistant integration, it is a strong option — but those willing to go long-throw can get slightly better picture quality and easier configuration for roughly the same price.
