Overview
LM250WQ4-SSA1 is an original IPS a-Si TFT-LCD module manufactured by LG Display. This 25-inch QHD display features 2560×1440 (Quad-HD) native resolution with a 16:9 widescreen ratio. Adopting In-Plane Switching (IPS) technology, it delivers symmetrical ultra-wide viewing angles, outstanding color consistency and stable visual performance.
Equipped with edge-type WLED backlight and 30-pin 4-lane eDP interface, this panel is widely known as the core screen for the Dell U2520DR professional monitor. It applies anti-glare surface coating with 3H hard coating to reduce ambient light reflection and resist scratches. Balanced brightness, high contrast and precise color reproduction make it ideal for professional office, graphic design, industrial display and visual monitoring equipment. All specifications are referenced from LG Display official datasheet to guarantee technical accuracy.

Frequently Asked Questions (FAQ)

Q1: Is LM250WQ4-SSA1 original LG Display panel?
A1: Yes. LM250WQ4-SSA1 is an original mass-production IPS LCD module from LG Display. It is the original matching panel for Dell U2520DR monitor. We supply Grade A new original panels with consistent datasheet parameters.
Q2: What interface does this panel use? Can I use LVDS driver board?
A2: It adopts 30-pin 4 Lane eDP (HBR1) interface. It cannot work directly with LVDS drive boards. An eDP signal driver board is required.
Q3: Does this screen support touch function?
A3: The bare panel has no built-in touch. Capacitive or resistive touch overlay can be customized and installed externally upon request.
Q4: What is the difference between LM250WQ4-SSA1 and LM250WQ4-SSA2?
A4: Different version variants have minor optimization on backlight circuit and power consumption. They are not fully interchangeable. Please confirm the exact model number before replacement.
Q5: Can this panel run continuously 24 hours a day?
A5: Designed for commercial continuous operation. It supports long-time daily use for office monitors. For 7×24 industrial uninterrupted operation, heat dissipation structure optimization is recommended.
Q6: What is the maximum supported refresh rate?
A6: Standard native refresh rate is 60Hz. Overclocking to higher refresh rate is not supported.
