A refurbished Unilumin UGN II rental cabinet that has already done its touring duty — now inspected, graded and priced for projects that need proven indoor hardware without a new-build budget.

Overview
The UGN II is Unilumin’s indoor rental cabinet: a die-cast frame with quick-lock hardware, 500 × 500 mm cabinet geometry and the clean, square proportions that make a flat, seamless wall easy to build.
This batch left the factory in 2024 and has been retired from event fleets — not resold as new stock. Because the real question with a used panel is never “does it light up” but “what condition is this lot in”, the rest of this page is built around that: the reference specification, the grading scale we apply, what we check before shipping, and what you actually receive with the quote.

What the numbers mean in practice
P3.91 is an indoor pitch that still looks clean at normal viewing distances — roughly 4 m and beyond. 800–1,200 nits is comfortable for halls, showrooms and control rooms, but it is not built to fight daylight outdoors. 3,840 Hz refresh keeps the wall stable on camera.
Anything that only the lot itself can answer — exact power draw, cabinet weight, receiving-card model, scan mode, connector type — is written on your quotation rather than assumed from the series name.
Condition, Grading and Warranty
First, we grade every cabinet on two things only: visual condition and service age. Moreover, we print the grade on your quotation, so price and condition always travel together. Consequently, you never compare an ungraded price with a graded one.
How the grades map to warranty
| Grade A | Cleanest stock available | 12 months |
|---|---|---|
| Grade B | Light service wear, fully functional | 12 months |
| Grade C | Visible cosmetic wear, fully functional | 6 months |
| Grades D–E | We quote Grade D as-is with full condition notes; meanwhile, we never sell Grade E panels and keep them only as internal repair stock | — |
What we check before it ships
- Cabinet identity and label check against the batch record
- Power-on and 72–96h full-brightness burn-in testing (see SOP)
- Module uniformity and dead-pixel review
- Rear electronics, power supply and connector inspection
- Accessory set and packing check against the quotation
Findings are documented per batch. You receive the inspection evidence with your quotation — not a generic series photo that could belong to any lot.
Workflow images are used to show the process; the photographic record for your specific batch comes with the quotation.
What's in the Box
Included with every cabinet
Furthermore, each cabinet ships with its original receiving card and matched power supply from the same production lot, rather than mismatched aftermarket parts.
Batch-dependent accessories
Power links, data cables, hanging hardware, spare modules and flight cases vary from lot to lot. In addition, we itemise all accessories on the quotation and show them in the inspection photos before payment. If your project needs a fixed accessory set, ask for the packing list before you order.
Where It Works Best
Typical applications
- Corporate interiors, lobbies and reception walls
- Retail and brand showrooms
- Control rooms and monitoring walls
- Studios and broadcast backdrops
- Education and auditorium screens
- Indoor video walls and event stages
Is P3.91 the right pitch for your room?
A 3.91 mm pitch is normally specified where the closest comfortable viewing distance is about 4 m or more; tighter rooms usually move to P2.6 or P1.9. Send us the viewing distance, screen width and installation height and we will confirm whether this batch fits — or point you to a closer pitch we actually have on the floor.
Customisation and OEM Support
Beyond single-cabinet replacement, we can discuss quantity matching, compatible cabinet replacement, screen-size planning, controller compatibility, packing and delivery coordination. Custom cabinet design, OEM production, special accessories, control-system changes and warranty scope are project-specific, and are always confirmed in writing before they enter a quotation.
Standards and Compliance
Our engineering review references IEC 62368-1 for AV/ICT equipment safety and IEC 60529 where an IP rating is claimed, alongside applicable EMC and RoHS requirements and local electrical and building rules. Finally, our engineers verify compliance marks, test reports, and environmental ratings for the actual lot rather than assuming them from the series name.
