Panasonic PT-REQ12
Panasonic PT-REQ12: body, lens, and projection position
Compare large-format presentation projection using the canvas, available distance, and optics required by the space.
Model and application
Documentation distinguishes PT-REQ12 with a supplied lens from PT-REQ12L using optional lenses. Confirm the complete body designation and lens code in the proposal; the family name alone does not define the supplied package.
Signal and optics
- Image
- 3840 × 2400 with Quad Pixel Drive enabled; the chip has 1920 × 1200 pixels. Image formation technology and input format are separate facts.
- Optics
- The PT-REQ12 supplied lens has a throw ratio of 1.36–2.10:1. Other lenses need their own table, compatibility, and installation conditions.
- Video and options
- HDMI and DisplayPort are documented inputs. Identify the installed expansion card; an empty slot does not provide a card’s inputs or functions.
System preparation
- Share the date, venue, image width and shape, planned light, and possible projector position. Photos and approximate measurements are enough to start.
- Select body and lens by code. Check optical distance, shift, and measurement reference before approving a mounting point.
- Define source, format, intermediate devices, and audio; test real content and save operating settings.
- Plan support, access, power, and beam area using exact documentation and qualified personnel before fixing height and walking routes.
Planning questions
- Does the proposal include the lens or just the body?
- How do we choose optics for a fixed projector position?
- Can I reuse a Panasonic lens from another series?
- What does Quad Pixel Drive mean for content?
- What if the direct source works but the full system does not?
- Can we start before choosing the lens or finalizing the program?
Does the proposal include the lens or just the body?
Identify both. Compare a supplied-lens configuration with optics compatible with the room’s distance. Distinguish PT-REQ12 from PT-REQ12L and specify screen, support, signal, configuration, and operation required by the program.
How do we choose optics for a fixed projector position?
Use width, aspect ratio, and distance from the optical reference with the official guide for the combination. Check height, shift, focus, and housing space as well as throw range. If it does not fit, compare size, position, or lens; lumens do not solve geometry.
Can I reuse a Panasonic lens from another series?
We need its exact code. The lens guide identifies compatible families and conditions; brand or mount appearance does not establish compatibility. Assess the existing lens before replacing it, and identify accessories or procedures specific to ultra-short-throw lenses.
What does Quad Pixel Drive mean for content?
The stated display resolution depends on enabling that feature; the chip should not be described as natively having the same resolution. Compare input format, scaling, and real content. For a wide presentation, agree on usable canvas and audience reading detail before exporting files.
What if the direct source works but the full system does not?
Test the same format and content in stages: source, cable, adapter or processor, and selected input. Record what each device detects and what changes when a segment is added. Identify an optional card before assigning it a format or connection.
Can we start before choosing the lens or finalizing the program?
Yes. Date, venue, content outline, and preliminary measurements let us prepare rental or purchase options and installation, configuration, and operation scope. Complete the body, optics, and required tests in the proposal rather than assume a universal combination.
Checks by symptom
| Image cannot fit from the fixed position | Check lens code, aspect ratio, and throw table before increasing digital correction. |
|---|---|
| Expected input is missing | Check body connectors and the actual expansion card, along with source and input selection. |
| Text or edge out of focus | Compare pattern and source; check lens, focus, alignment, and surface with the real system. |
Use and safety
Optical safety review depends on body, lens, and installation. Plan access control and beam path using the exact procedure; do not look into the lens.
Keep ventilation and service access clear. Lens changes and internal tasks follow the combination’s documentation and require qualified personnel.
