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 alright for a home theater. It has great contrast in dark scenes, and it does an excellent job of maintaining fairly deep blacks in bright scenes. Motion is smooth in movies and shows if you're using a modern streaming device like an Apple TV. However, motion looks choppy if you're using an older cable box, since it doesn't remove judder from 60Hz sources. Unfortunately, despite having decent brightness, colors really lack vibrancy and look washed out. On top of that, color accuracy is poor out of the box, and most colors are too warm, so it doesn't faithfully reflect the filmmaker's intent. There are also rainbow flashes that can bother people who are sensitive to them.
The image has solid depth thanks to its great contrast.
Decent enough brightness that the image doesn't look dim.
Manual optical zoom helps with setup.
Poor color accuracy out of the box.
Colors look washed out.
Rainbow flashes will bother those who are sensitive to them.
No internal apps.
Doesn't remove judder from older devices.
The BenQ TH575 is mediocre for use outdoors. It has decent brightness, so the image doesn't look too dim at night. However, it's still best to wait until the sun goes down, since ambient light makes the image look faded. It has okay portability, mostly because it's light and easy to move around, but setting it up is a manual process that requires some time. It also needs to run on AC power, and it doesn't have a carrying handle, a case, or lens protection, so it's not a very good option to bring on a camping trip.
Decent enough brightness that the image doesn't look dim.
Small and light enough to easily carry around.
Lack of automatic setup features.
No handle, case, or lens protection.
The BenQ TH575 is inadequate for a bedroom. It's pretty light for its size, so carrying it into your bedroom isn't a big hassle, but it requires manual focus and doesn't have lens shift, so you really need to center it on the screen and take some time setting it up to get a usable image. Furthermore, you need a decent amount of space between the projector and your screen or wall to project an image, so it's not suitable for small bedrooms. The fan is fairly quiet, but you will hear it if you're sitting close to the projector, which can be distracting.
Small and light enough to easily carry around.
Lack of automatic setup features.
No handle, case, or lens protection.
Image can't be projected onto a ceiling.
The BenQ TH575 is alright 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.

Decent enough brightness that the image doesn't look dim.
Low input lag with Fast Mode enabled.
Poor color accuracy out of the box.
Colors look washed out.
Limited to 1080p @ 60Hz.
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.
Decent enough brightness that the image doesn't look dim.
Relies heavily on white light to increase brightness, which dilutes colors.
The BenQ TH575 has great contrast. Since blacks are deep across all brightness levels, dark scenes have very good depth, and it does an excellent job of maintaining that depth in brighter scenes.
The image has solid depth thanks to its great contrast.
The BenQ TH575 has okay portability. It's a mid-size projector that isn't designed to be portable, but it's quite light, so moving it between rooms isn't a big hassle. However, it lacks autofocus or lens shift, and you must center it on the screen you're projecting onto to get the best image quality, so setting it up takes some time. It also doesn't have a built-in battery, so it needs to be plugged into an outlet.
Small and light enough to easily carry around.
No internal apps.
Lack of automatic setup features.
No handle, case, or lens protection.
No built-in battery.
The BenQ TH575 has poor colors. Colors really lack saturation and look washed out, so the image looks flat and dull. It also has poor color accuracy out of the box, with most colors appearing warmer than intended, so it doesn't faithfully reflect the content creator's intent.
Poor color accuracy out of the box.
Colors look washed out.
The BenQ TH575 has okay gaming responsiveness. It's limited to 1080p @ 60Hz, so gaming at higher refresh rates isn't supported, and it doesn't support VRR to reduce screen tearing. Fortunately, it has low enough input lag that you don't feel a delay between your inputs and the action on the screen. There also isn't excessive motion blur thanks to its DLP imaging.
Low input lag with Fast Mode enabled.
Limited to 1080p @ 60Hz.
No VRR to reduce screen tearing.

Differences Between Sizes And Variants
We tested the BenQ TH575 projector, which has no variants. BenQ also sells similar 1080p home theater/gaming projectors, including the BenQ TH671ST. However, the TH671ST is a separate short-throw model, whereas the TH575 uses a standard-throw lens, so our review applies only 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 has 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 bare-bones, 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 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 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 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.
