BenQ TH575

Quick verdict: The BenQ TH575 keeps things simple: a Full HD picture for occasional movies and 1080p60 games, provided you have room for the projector and already own a streaming device. BenQ's 3,800 ANSI lumens and 16.7 ms at 1080p60 are maker specifications, not PIQSY measurements. The selected US product is TH575 9H.JRF77.13A, not TH575i. Its biggest buying catch is supply: the checked BenQ and Best Buy US pages do not show a new unit ready to buy, and the genuine replacement lamp is available from B&H only as special order.

Best for: A dimmable room with adequate shelf-to-screen distance, a console or streaming device already available, and a shopper willing to factor replacement-lamp ownership into the decision.

Skip it if: You need 4K detail, battery portability, integrated smart TV, short-throw geometry or a confirmed new US factory-kit match before purchasing.

Who it fits

Not everyone needs a projector with a laser engine, a sophisticated gaming menu and a premium price tag. Sometimes the goal is a 100-inch movie night or weekend console session, and a straightforward Full HD device is enough.

The TH575 sits in that role. It focuses on a bright manufacturer-rated picture and simple HDMI source connectivity rather than built-in Google TV or a motorized optical system. If your console or streaming stick already handles the apps, this simplicity may be a benefit rather than a missing feature.

The precise name is important. BenQ also markets TH575i in some listings and regions. You must not assume a TH575i package, streaming accessory or seller warranty comes with the ordinary TH575. The owner's selected US candidate remains the non-i TH575.

What changes the decision

1080p can be useful when the screen and distance are sensible

The TH575 uses a DLP projection system with 1920×1080 output. On a movie screen at a normal seating distance, that can deliver a satisfying large image. It will not show fine 4K detail simply because you connect a 4K-capable source, and the precise source-format compatibility must be checked.

If your use includes tiny computer text or gaming HUD elements at a very large scale, a higher-resolution model may be worth the difference. If you mainly watch sports and sitcoms from a sofa, light control, focus and screen size may matter more.

BenQ publishes 88% Rec.709 color coverage. That is a manufacturer gamut claim, not an independently verified color-accuracy measurement. A projected image can be vivid without reproducing every intended shade perfectly.

A large picture also makes compression artifacts more obvious. A clean source and careful focus help more than stretching a poor-quality stream onto the biggest possible wall.

Brightness sounds strong, but the viewing mode matters

BenQ lists 3,800 ANSI lumens. This is a rated output figure, not a PIQSY measurement of the TH575 in Cinema or Game mode. The brightest mode may have different color characteristics from the one you prefer for movies.

This rating makes the model worth considering for a mixed-use dimmable room. It does not mean direct sunlight on a white screen stops mattering. Brightness per square foot falls as you make the image larger, and surrounding light can make blacks look gray.

The stated 15,000:1 FOFO contrast is a manufacturer's full-on/full-off figure, not a standardized independent native contrast result. Don't compare it numerically with a dynamic iris or laser contrast figure from another brand as though the methods were the same.

For a good family movie night, start with curtains and a sensible picture size. If midday viewing is your main activity, a television may solve the problem more reliably than a modest projector regardless of its luminous rating.

Throw geometry is less forgiving than the price tag may imply

BenQ specifies a 1.49–1.64 throw ratio and 1.1x optical zoom. A 100-inch 16:9 image is about 87 inches wide, which yields a rough lens distance of 10.8–11.9 feet. This is a planning estimate; check the manufacturer's projection calculator and full chassis clearance.

For a short apartment living room, that can be a significant limitation. You might be forced to mount the projector behind the couch, run cables across the room or accept a smaller image. A short-throw product such as BenQ X500i or TK705STi may fit better despite a different overall feature set.

The TH575 offers automatic vertical keystone correction. That can help square a small alignment error, but it changes picture geometry digitally. It does not make the lens behave like a short-throw design or compensate for an unsuitable shelf position.

Measure room depth before considering any deal. A low price on the wrong lens class can become expensive once mounts, cables or replacement furniture are needed.

Gaming is casual and 60Hz-oriented

BenQ quotes 16.7ms at 1080p60 for the TH575. That's a manufacturer claim for a specific mode, not an independent PIQSY test. Its HDMI 1.4a ports, rather than HDMI 2.1, and published scan information don't establish reliable 1080p120 competitive gaming.

For a weekend film, sports or party-game night, a large 1080p60 picture can be plenty of fun. But if you live for 120Hz or 240Hz competitive play, shop for a projector with those clearly documented outputs and comparable lag tests.

Don't compare this 16.7ms at 1080p60 figure with a rival's 4.2ms at 1080p240 and assume the second will always feel faster. They're different conditions. If gaming is occasional, focus more on room depth, light control and easy connections.

The lamp is a maintenance and availability decision

The TH575 uses a conventional replacement lamp, rated by BenQ for 6,000 hours Normal, 10,000 hours Eco or SmartEco, and up to 15,000 hours LampSave. Those are maker estimates under different settings, not a promise of steady maximum brightness for all those hours.

If you watch an occasional weekend film, lamp upkeep may not be a huge concern. If you stream for hours every day, the cost and availability of replacements become more important.

BenQ identifies genuine lamp 5J.JNG05.001, but its US store reports the part out of stock. B&H lists it as special order with an estimated two-to-four-week wait, not immediate delivery. Check how you'd obtain a replacement before committing to an older lamp-based model.

Other parts can still require service, so a dependable seller and an appropriate warranty matter too.

Straightforward connections mean separate smart entertainment

BenQ lists two HDMI 1.4a inputs, a 10W internal speaker, audio input/output jacks and a USB-A power-supply port. This is enough to connect a console and streaming stick without pretending the projector includes its own licensed smart-TV app environment.

That simple design can be convenient when you already use external sources. But if your expectation is to log into Netflix with a single projector remote and no extra equipment, the TH575 is not the right form of all-in-one entertainment.

The speaker rating doesn't establish movie-quality sound in a large room. If dialogue and surround effects matter, confirm how you will connect an external soundbar or audio system. A projector's audio output options may be adequate for a simple setup, but shouldn't be confused with HDMI eARC features found on newer models.

Cooling and noise can also be noticeable when a lamp projector sits near viewers. BenQ publishes operating-noise ratings under particular modes. Your room and projector position decide whether the fan will be distracting.

The exact US model is known; new supply is the catch

The exact non-i US model is TH575 9H.JRF77.13A, with UPC 840046047740 at Best Buy. BenQ confirms the key 1080p, 3,800 ANSI and 16.7ms at 1080p60 specifications and names genuine lamp 5J.JNG05.001.

The shopping catch is stock, not which model we're discussing. The previously checked BenQ US store shows the projector out of stock, while Best Buy does not show its original new-condition offer as available.

Treat TH575 as a conditional alternative, not an uncomplicated current new-buy recommendation. If you find exact new 9H.JRF77.13A, check warranty, factory box and lamp supply. Don't accept a TH575i or a refurbished kit as automatically equivalent.

Owner feedback

We haven't found enough reliable owner reports for the exact US TH575 to judge long-term problems. Comments on TH575i or broad BenQ ratings may relate to different equipment. Check genuine replacement-lamp supply and seller support before relying on a star average.

Who should choose something else

Choose the ViewSonic PX701-4K if 4K output and a documented 1080p240 gaming input option matter more than simple Full HD projection. Both use traditional lamps, so neither avoids replacement-light-source considerations.

Choose the BenQ TK705i when integrated Google TV, a 4LED source and more flexible placement are worth the difference to you. Its manufacturer-rated gaming figures apply to specified modes, not every processing setting.

Choose the BenQ TK705STi when a shorter room cannot accommodate the TH575's approximately eleven-foot lens distance for a 100-inch picture. Room fit should override generic value rankings.

Before you buy

Verify TH575 9H.JRF77.13A, UPC 840046047740 if listed, new versus refurbished condition and actual warranty. BenQ's genuine 5J.JNG05.001 lamp is out of stock direct and special order at B&H, so don't assume immediate replacements. Measure your screen distance and plan a separate streaming source if needed.

PIQSY conclusion

The BenQ TH575 still makes sense for someone who owns one or can obtain the exact US new unit with an acceptable warranty and genuine replacement-lamp plan. Its simple Full HD picture can suit occasional games and movies, but the longer room depth and 1080p60 gaming limit still matter.

It is not an uncomplicated new-buy recommendation while the previously checked new-stock routes are unavailable. Don't chase an appealing old listing without checking what is actually for sale.

Before buying: Verify non-i TH575 9H.JRF77.13A, UPC 840046047740, and genuine lamp 5J.JNG05.001. BenQ and Best Buy had not established new availability; the lamp was out at BenQ and special order at B&H. Confirm current seller details rather than assuming stock.
