The BenQ TH575 is a basic 1080p DLP projector designed for living-room movies, sports, and casual gaming. It's a traditional lamp-based projector, so it's more about delivering a simple big-screen image than offering modern smart features or an all-in-one streaming experience. Its standard-throw lens, manual optical zoom, adjustable feet, and auto vertical keystone correction give you some flexibility when placing it on a table or mounting it permanently. You'll need to connect your own media source, as it doesn't have a smart OS, built-in casting, Wi-Fi, or Bluetooth. It has two HDMI ports for devices like a streaming stick, game console, Blu-ray player, or PC, while its USB-A port can power some small streaming devices. It also includes analog audio in and out, a built-in 10W speaker for basic sound, and an RS-232 port for more advanced control in custom installations.
Our Verdict
The BenQ TH575 is decent for watching movies in a dark room. Its main strength is contrast: dark scenes have good depth, and the image holds up well in mixed-brightness scenes, even if it struggles with near blacks. Its brightness is decent, so you don't absolutely need to turn off every light in the room to see the image. However, its out-of-the-box accuracy is poor, with inaccurate colors and a warm grayscale. Its color gamut is also limited, and HDR looks washed out, so it's not the best choice if you want your movies to pop.
Great contrast, especially in mixed and brighter scenes.
Bright enough for dimmer rooms.
Manual optical zoom helps with setup.
Poor color accuracy out of the box.
Narrow color gamut.
HDR looks washed out; stick to SDR.
Contrast struggles with near blacks.
The BenQ TH575 is decent for casual 1080p gaming at 60Hz. It has low input lag, and its strong contrast gives games decent depth in a dark room. However, it's limited to 1080p @ 60Hz, with no 4k or high-refresh-rate support, so it can't take full advantage of modern consoles or high-refresh-rate PC gaming. It's also not very colorful, so your games won't exactly pop off the screen.
Great contrast, especially in mixed and brighter scenes.
Bright enough for dimmer rooms.
Low input lag with Fast Mode enabled.
Poor color accuracy out of the box.
Narrow color gamut.
HDR looks washed out; stick to SDR.
Limited to 1080p @ 60Hz.
Contrast struggles with near blacks.
The BenQ TH575 is bright enough for casual living-room use, but it looks its best with the lights dimmed. Unfortunately, bright whites stand out more than saturated colors, and the image can look less colorful in its brightest modes, so it's not optimal if you want your colors to also be bright. There are also some noticeable uniformity issues if you look closely.

Some noticeable uniformity issues on plain white screens.
The BenQ TH575 has great contrast. Most dark scenes have good depth, though it struggles with near-black tones, so very dark movies, like many horror titles, can look a bit gray at times. Still, it shows a strong contrast in both bright and mixed scenes, making bright scenes relatively punchy.

Differences Between Sizes And Variants
We tested the BenQ TH575 projector, which doesn’t have any variants. BenQ also sells similar 1080p home theater/gaming projectors, including the BenQ TH671ST. However, the TH671ST is a separate short-throw model, while the TH575 uses a standard-throw lens, so our review only applies to the TH575.
Our unit was manufactured in February 2026.
Popular Projector Comparisons
The BenQ TH575 has some major color-related flaws, as it's very inaccurate out of the box and has a narrow color gamut. Still, it's otherwise a solid projector for most use cases, as long as you don't mind its basic feature set, washed-out HDR, and lack of a smart OS. It's relatively bright, and its contrast is great outside of the darkest scenes. It's limited to 1080p @ 60Hz, and it does have noticeable RBE, but it has very low input lag, making it a solid gaming option if you don't care about 4k or high-refresh-rate gaming. Its closest alternative is the short-throw BenQ TH671ST, which is much more accurate and colorful, but has worse contrast and isn't as bright. Other options include the brighter Epson Home Cinema 1080, which is similarly barebones, or the more fully featured Epson Lifestudio Pop Plus; both are more accurate than the BenQ, but have worse contrast and are much worse for gaming. Overall, the TH575 is a solid pick at its price point.

The Epson Home Cinema 1080 and BenQ TH575 have different strengths, so they work for different needs. The Epson is a light cannon; bright enough for rooms with some ambient light. It's also very accurate out-of-the-box. That said, it's rather noisy under load and has very high input lag, making it a poor choice for gaming. The BenQ isn't quite as bright, but its contrast is way better, making it better in darker rooms. Unfortunately, it's not nearly as accurate as the Epson. It does, however, have much quicker input lag, making it a solid 1080p @ 60Hz gaming projector.
The BenQ TH671ST is a bit better than the BenQ TH575, but you might prefer the latter based on what you prioritize. The TH575 is brighter and has vastly better contrast, so it does project a more striking image at times. However, the TH671ST is much more accurate and has a much wider color gamut, so more colorful content looks more vibrant and natural on that unit.
The BenQ TH575 is better than the Epson Lifestudio Pop Plus, except if you want very accurate colors or a more portable device with a smart OS; in that case, go with the Epson. Otherwise, the BenQ is brighter, has much better contrast, and is better for gaming due to its lower input lag. You'll just need to provide your own external streamer, as the BenQ comes with just the basics.
We've independently bought and tested over 80 projectors and published detailed results for each, so you can decide which one to buy. These have all been tested under the same standardized methodology, allowing you to compare them side by side. We still have all these projects in our lab, so we can continually go back and compare them to ensure our reviews are still accurate. All our test methodologies are also public on our website, so you can validate the results yourself.
