Frequently Asked Questions (FAQ)

Can I use the LM340UW2-SSA1 to repair my Acer XR341CK or similar 34" ultrawide monitor?

Yes, the LG Display LM340UW2-SSA1 is the original OEM panel used in many flagship 34-inch 3440x1440 curved monitors, including models from Acer and ASUS. However, we always recommend opening your current monitor to verify the exact model number printed on the back of the metal chassis before ordering.

Is this a true 10-bit color depth panel?

Yes, the LM340UW2-SSA1 features AH-IPS technology capable of displaying 1.07 billion colors (10-bit). This makes it an excellent choice for professional color grading, photography, and video editing where color banding must be avoided.

How do you ship a curved 34-inch LCD panel safely?

Curved panels are highly susceptible to pressure cracks. At ZY LCD Shop, we pack the LM340UW2-SSA1 in a custom-fitted, shock-absorbent styrofoam box with reinforced cardboard corners and anti-static shielding, ensuring it arrives in perfect condition regardless of the destination.

Do you offer wholesale pricing for monitor repair shops?

Absolutely. If you are an electronics repair technician or require multiple units of the LG Display LM340UW2-SSA1 for your business, please contact us directly for customized B2B wholesale pricing.
