LG 55XS4P-B — 55-inch Full HD 4,000-Nit Window-Facing Display
The LG 55XS4P-B brings 55 inches of 4,000-nit brightness to the storefront window — an IPS (M+) direct-LED panel that holds vivid color and a 500,000:1 dynamic contrast ratio against full daylight. Anti-Discoloration technology helps the picture resist screen-yellowing over years behind glass, and Upgraded Quiet Mode keeps it calm. Runs webOS 6.0 signage and is backed by LG's 3-year commercial warranty.

Features that matter for the LG 55XS4P-B
4,000-Nit Sunlight-Beating Brightness
Eight times brighter than a typical indoor panel, the 55XS4P-B punches through daylight and reflected glare to stay vivid and legible to people on the sidewalk outside the glass.
500,000:1 Dynamic Contrast
A high dynamic contrast ratio keeps blacks deep and highlights bright, so promotional artwork and motion content stay punchy and high-impact even at full window brightness.
UL-Verified Anti-Discoloration
High-brightness panels can yellow with age. LG's Anti-Discoloration technology resists that shift — and per LG, the XS4P is the world's first display with UL Verification for Display Anti-Discoloration.
Upgraded Quiet Mode
Upgraded Quiet Mode runs the panel at 2,500 nits with minimal fan noise — still bright enough for many daylight hours, and quiet enough for a calm retail or office interior right behind the glass.
LAN Daisy-Chain Control
Link multiple XS4P units over LAN and control them as one — ideal for a row of window displays along a wide storefront, managed and updated together without per-screen cabling runs.
webOS 6.0 + Wireless Connectivity
webOS 6.0 signage plays content on board, and built-in Wi-Fi, Bluetooth, and Beacon support open up flexible content delivery and customer-engagement options at the storefront.

Procurement FAQ
What is the official model number for the 55XS4P-B?
55XS4P-B — the 55-inch model in LG's XS4P-B high-brightness window-facing signage line. Confirm the model number at quote stage so you receive the 4,000-nit window display rather than a standard indoor panel.
Why does the 55XS4P-B need 4,000 nits of brightness?
A window-facing display competes with daylight. At 4,000 nits the 55XS4P-B stays vivid and readable when mounted behind storefront glass in direct sun, where a typical 500-nit indoor panel would wash out completely.
Is the 55XS4P-B an outdoor display?
It is a window-facing display: built to sit indoors behind glass and beam outward to the street. It is not weather-sealed for full outdoor exposure. For drive-thru and open-air installs use LG's fully outdoor signage range.
What is Anti-Discoloration on the XS4P?
Anti-Discoloration is an LG technology that resists the screen-yellowing high-brightness panels can suffer over time. LG states the XS4P is the world's first display to earn UL Verification for Display Anti-Discoloration, which helps the picture hold true color across a long service life behind glass.
Is shipping included?
Yes. Every order ships free. In-stock units leave the warehouse within about 2 business days, and any backorder is quoted with a written lead time before you commit.
Do you accept purchase orders?
Yes. POs are accepted from qualified business, government, education, and non-profit accounts, and tax-exempt orders are processed with valid documentation. DisplayDetails is an LG commercial display specialist.
Can DisplayDetails handle installation?
Yes. We coordinate professional installation nationwide — window-facing mounting hardware, heat and ventilation planning behind glass, signal cabling, and content commissioning, managed by one project contact from quote through go-live.
What warranty applies?
A 3-year LG commercial warranty covering parts and labor. DisplayDetails registers the warranty at fulfillment. See the official LG product page linked below for current terms.
Compatible accessories
- Mounts (commercial-grade, VESA-compliant): ceiling-suspended and floor-standing window mounts, plus portrait-capable wall mounts for window-facing high-brightness displays.
- Players & CMS: webOS 6.0 signage is built in; add a BrightSign XT4 or LS424 for dedicated external playout if preferred.
- Signal extenders: HDBaseT extender kits carry HDMI over Cat6 for runs from a back-office source to the window.
- Cabling: Premium High Speed HDMI, Cat6 STP for LAN daisy-chain and HDBaseT, and RS-232C control cable.
