BenQ GP520 Review: The Budget Projector That Doesn't Need a Dark Room
Under $1,500, brightness is the spec that decides everything, and the GP520 wins it with an honest 2,600 lumens. What it gives up is color and black level, and it is upfront about both.

Almost every projector under $1,500 has the same flaw, and it is not the one buyers worry about. People shop this price bracket looking for 4K. What they should be looking for is light.
A budget projector with a beautiful, sharp, color-accurate image that only works in a blacked-out room is a projector that gets used four times and then lives in a closet. The BenQ GP520 is the budget pick in our rankings because it is bright enough to survive a real room, and because BenQ told the truth about how bright.
An honest 2,600 lumens
BenQ rates the GP520's 4-LED engine at 2,600 ANSI lumens, and independent testing puts it right at spec. Home Theater HiFi and TechRadar both confirmed it meets the rating. Expert Reviews noted it comfortably beats the 1,800-lumen Nebula Cosmos 4K SE and the Horizon S Pro, its closest rivals.
Eight hundred lumens does not sound like a lot until you understand what it does. At 1,800 lumens, you close the curtains or you do not watch. At 2,600, you can leave them half open on an overcast afternoon and still see the picture. That is the difference between a projector you use and a projector you own.
The image itself is genuinely sharp: true 4K by pixel-shifting from a 0.47-inch DLP chip, through a good lens, edge to edge, up to 180 inches. At this price, that combination of brightness and sharpness has no real competition.
The setup is the easiest BenQ has made
Autofocus, auto-keystone, auto-framing, obstacle avoidance, and wall-color correction. Move the projector, and it squares itself up and compensates for the fact that your wall is beige. It sounds like feature-list padding and it is not: for a projector that will get carried between rooms rather than permanently mounted, the difference between a fifteen-minute alignment ritual and a fifteen-second one determines whether you bother.
It runs Google TV with Netflix, Prime, and Disney+ built in, casts from Google Cast and AirPlay, and its dual 12-watt speakers are among the better built-ins in the class. Loud enough and clear enough that most people will not add a soundbar for casual watching.
What $1,499 does not buy
BenQ made specific, defensible cuts, and you should know exactly where.
Color coverage is modest: about 81% DCI-P3. It is accurate within that range and it looks perfectly good. But it is not the vivid, saturated wide-gamut image a triple-laser projector produces, and if you put the GP520 next to a Hisense C2 Ultra covering 100% DCI-P3, you will see the gap instantly. There is no Dolby Vision either, only HDR10, HDR10+, and HLG.
Black levels are elevated. Dark scenes lose depth. This is the standard budget-DLP compromise and the GP520 does not escape it.
The Google TV processor is underpowered. Menus hang for a beat. It is not broken, it is just a little slow, and it will annoy you occasionally for as long as you own it.
Gaming caps at 4K/60, with about 18ms of lag. Fine for casual play, not for anything competitive.
Who should buy it
Buy the GP520 if you want the brightest, sharpest true-4K picture available near $1,500, with streaming and sound already inside the box, and you accept that vivid color and inky blacks are what you traded away. For a living room, a playroom, a first projector, or anyone who wants a big picture without building a home theater around it, it is the right amount of projector.
If you need it to be portable in the real sense (a battery, a bag), the Nebula Capsule 3 Laser is a completely different proposition at $599, and eight times dimmer. If you can stretch the budget substantially, the step up to a triple-laser projector buys you the color and contrast the GP520 gives up, and it is a real step. But nothing near $1,500 puts more usable light on a wall than this.
