Overview

A Samsung QLED television, model QN43LS03DK1, with a 43 inch screen and 4K UHD resolution. The listing's smart platform field reads Windows and its connectivity field reads RCA, both unusual for a modern Samsung TV, so confirm those two details against the product page before relying on them.

Most of this model's core specs, screen size, resolution and QLED panel type, are stated plainly, but the smart platform and connectivity entries stand out from typical Samsung sets and are worth double-checking with the seller or listing images.
