BenQ TH575C 1080p 3800lm Home Theatre Projector
PRODUCT DESCRIPTION
BenQ TH575C 1080p 3800lm Home Theatre Projector (TH575C) - Local Warranty Support
Lamp Light Source: Lowest Entry Price, Serviceable Lamp Module
The TH575C uses a conventional projection lamp rather than LED or laser, and that is exactly why it costs what it does. BenQ rates the lamp at 6,000 hours in Normal mode, 10,000 hours in ECO and SmartEco, and 15,000 hours in LampSave mode. The lamp is a replaceable service part, so when it reaches end of life the projector carries on with a new module instead of being retired. For a household that uses a projector for a few hours a week, or for a classroom or function room where the unit is not on all day, a lamp model is the sensible way to buy brightness.
3,800 Lumens for Rooms You Cannot Fully Darken
At 3,800 ANSI lumens the TH575C is bright enough to hold a watchable Full HD image in a living room with the lights on or with daylight coming through half-closed blinds. That is a different design goal from a dim, deep-contrast cinema projector: this model is built to win against ambient light rather than to chase black level in a blacked-out room. Contrast is a published 15,000:1 with 30-bit colour processing for 1.07 billion colours, and the 10W speaker means it can be set up and used without an external sound system.
Derived From the MH560, Rebuilt Around HDMI
The TH575C is derived from BenQ's MH560 meeting room projector, with the legacy analogue connections removed. There is no PC D-sub input or output, no composite video input and no S-video input on this model; the video path is HDMI, with USB Mini-B, RS-232 and a 3.5mm audio output retained for control and sound. For a home or hospitality installation fed entirely by HDMI sources, dropping the analogue ports simplifies the back panel without losing anything that gets used. Buyers who still need D-sub and legacy video should look at the MH560 instead.
16.7ms Input Lag and 1.1x Zoom for Everyday Setup
BenQ publishes 16.7ms input lag at 1080p 60Hz, which keeps console and PC gaming responsive on a big screen. A 1.49 to 1.64 throw ratio with 1.1x zoom puts a 100-inch image between roughly 3.3 and 3.6 metres from the screen, a normal living room or classroom depth, and 1D auto vertical keystone of +/-40 degrees squares the picture when the projector sits on a table rather than dead centre. At 2.3 kg it is light enough to carry between rooms or to a function space and set up in minutes.

Compatibility & Installation
Throw distance and screen size
Throw ratio is 1.49 to 1.64 with 1.1x zoom, so throw distance equals screen width multiplied by that ratio. A 100-inch 16:9 screen is 2.21 metres wide and needs roughly 3.3 to 3.6 metres; a 120-inch screen is 2.66 metres wide and needs roughly 4.0 to 4.4 metres; an 80-inch screen is 1.77 metres wide and needs roughly 2.6 to 2.9 metres. Projection offset is 108%.
Mounting and alignment
Table and inverted ceiling mounting are both supported. 1D auto vertical keystone of +/-40 degrees corrects for a projector that sits below or above screen centre. There is no horizontal keystone on this model, so aim to place the unit on the screen's centre line left to right.
What it connects to
The video path is a single HDMI 1.4a input with HDCP 1.4, which suits a streaming box, a Blu-ray player, a console or a laptop. This model does not carry a PC D-sub input or output, a composite video input or an S-video input - those were on the MH560 it is derived from and have been removed here. RS-232 and USB Mini-B are provided for control and service, and audio leaves over the 3.5mm output or the built-in 10W speaker.
Network and content
There is no built-in smart platform, no Wi-Fi and no network port on the TH575C. Streaming is handled by whatever device is plugged into HDMI - a Google TV or Fire TV stick, a set-top box or a laptop.

Frequently Asked Questions — BenQ TH575C
What light source does it use, and how long does it last?
The TH575C is a lamp projector. BenQ rates the lamp at 6,000 hours in Normal mode, 10,000 hours in ECO and in SmartEco, and 15,000 hours in LampSave mode. The lamp is a serviceable module, so it is replaced rather than the whole projector when it reaches end of life.
How does a lamp compare with the LED and laser models?
A lamp gives the lowest purchase price per lumen and is a consumable: it dims gradually and is eventually replaced. LED models such as the TK705i and laser models such as the LH655 are rated at 20,000 hours Normal and 30,000 hours ECO with no lamp module at all, so they cost more up front and less to run. For light or occasional use a lamp is usually the better value; for a projector that runs daily, solid state pays back.
Is it 4K?
No. The TH575C has a native 1080p (1920 x 1080) panel. It is listed alongside BenQ's 4K home models because it sits in the same home entertainment range, but the resolution is Full HD.
How is the TH575C different from the MH560?
The TH575C is derived from the MH560 with the legacy connections removed: there is no PC D-sub input or output, no composite video input and no S-video input on this model. The video path is HDMI only. If you need those analogue ports, the MH560 remains the right choice.
Does it have built-in streaming apps?
No. There is no smart platform, no Wi-Fi and no network port. Plug a streaming stick, a set-top box or a laptop into the HDMI input.
How far back does it need to sit?
The throw ratio is 1.49 to 1.64 with 1.1x zoom. A 100-inch 16:9 screen is 2.21 metres wide, so it needs roughly 3.3 to 3.6 metres of throw distance. A 120-inch screen needs roughly 4.0 to 4.4 metres.
Can I use it for gaming?
BenQ publishes 16.7 ms input lag at 1080p 60Hz for this model, which is responsive enough for console and PC gaming at Full HD.
Does it come with a Singapore warranty and a GST invoice?
Yes. Every unit sold by SourceIT is supplied with local Singapore warranty support and a GST invoice. BenQ's projector warranty terms vary by model, and the lamp is normally covered on its own separate terms, so please ask us to confirm both in writing with your quotation.
