Our take
TH585P is a home-entertainment projector with a well-specified core: native Full HD, 3500 ANSI lumens, conventional throw, and a stated 16.7 ms input lag at 1080p/60 Hz. These figures make it easier to compare with other home projectors than a listing whose lumen basis is unclear. It remains a lamp-based AC model with no documented app platform. The historical title's streaming language does not mean Netflix or Prime Video are built in; plan to connect an external player.
Home movies and console gaming in a room with adequate throw distance and a separate source device.
It is not suited to battery use, ultra-short-throw rooms, built-in streaming without another device, or anyone who requires native 4K rather than Full HD.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- BenQ documents native 1920 × 1080 resolution and 3500 ANSI lumens.
- A 16.7 ms 1080p/60 Hz input-lag specification targets responsive gaming use.
- The 1.5–1.65:1 throw range and 1.1× zoom provide defined placement constraints.
What to weigh up
- Full HD is below native 4K and does not become 4K when connected to a UHD source.
- The lamp, room-depth requirement, and lack of built-in streaming need planning.
- Lamp hours, current condition, seller package, and the historical offer are unknown.

What the features mean for you
A home model with a specific gaming claim
BenQ places TH585P in its home-entertainment and gaming lineup. The model page gives a 16.7 ms input-lag figure at 1080p and 60 Hz, which is a published specification rather than a result from our own measurement. That makes it relevant for console users comparing the source-to-image delay claims of different models. It does not guarantee the same delay under every resolution, refresh rate, signal path, or game. A buyer should check that their console and connection use the conditions tied to BenQ's rating and weigh those against the size and lighting of the room.
Native Full HD and ANSI brightness are clearly stated
BenQ specifies 1920 × 1080 native resolution and 3500 ANSI lumens. The native pixel count is Full HD, not 4K; high-resolution source compatibility does not alter it. The ANSI label also makes this brightness figure more comparable with models using the same standard, although a rated number is not a measurement of a used lamp. Screen size, image mode, ambient light, and lamp age still matter. This combination can be useful for movies and gaming, but buyers seeking detailed native 4K should shortlist a model with that imaging-device resolution explicitly documented.
Measure for the 1.5-to-1.65 throw range
TH585P has a 1.5–1.65:1 conventional throw ratio and a 1.1× optical zoom. That means the projector needs meaningful room depth and cannot replace an ultra-short-throw model sitting near a wall. Measure the screen width and lens distance before selecting a ceiling mount or shelf. A modest optical zoom gives a limited adjustment window, not free placement. The saved specifications do not establish optical lens shift; plan a centered position and avoid relying on keystone correction as a substitute for physically aligning the projector with the screen.
Streaming requires a separate player
The TH585P's source connections allow an external streamer, console, computer, or disc player. BenQ does not list an integrated consumer streaming-app platform in the saved model specifications. That difference matters because the candidate title advertises that it can stream Netflix and Prime Video: the projector can display a compatible signal, but the services are not documented as built in. Choose an HDMI source and check any needed audio route before installation. This setup may suit someone who already uses a console or streaming stick, but it is less self-contained than a smart projector with documented apps.
A used lamp unit needs a careful condition check
The official model rating describes a new-spec TH585P, not the operating history of a particular listing. Ask for lamp hours and check the image, focus, color uniformity, HDMI ports, remote, fan, and power cable. Confirm the exact TH585P label and whether any promised accessories are included. The projector uses a replaceable lamp rather than an internal battery, so it is designed around an outlet and conventional room placement. No current offer, price, stock position, or seller warranty is confirmed by this review; those details must be checked separately for the exact unit.
What else to compare
For 4K PRO-UHD output and horizontal/vertical lens shift, compare Epson Home Cinema 3200; for a more portable battery setup, compare ASUS ZenBeam S2 and accept its lower 720p detail and non-ANSI output.
Before you buy
Is the TH585P native 4K?
No. BenQ specifies a native 1920 × 1080 Full HD image; 4K input support does not change the imaging resolution.
What brightness does BenQ list?
BenQ specifies 3500 ANSI lumens for the TH585P, a manufacturer rating rather than a measurement of an individual used lamp.
Does it include Netflix or Prime Video apps?
The saved BenQ material does not document built-in streaming apps. Connect a compatible external HDMI player for those services.
