Historical Product Info

Official launch details

Instead of tracking today's retail price, Kacbu keeps the product's official launch information as a reference.

Design🇰🇷 South Korea

LG designs its displays in South Korea. Its specification pages state no assembly country, so none is claimed here.

This is not the current retail price — it shows the product's historical, official launch information.
