LG 50UA73006LA

The LG 50UA74006LB and LG 50UA73006LA are closely matched 50-inch 4K smart TVs built around LG's α7 AI Processor 4K Gen8 and WebOS 25 platform. Both offer HDR10, HLG, AI-powered upscaling, Game Optimizer, VRR up to 60Hz, and access to popular streaming apps. The differences are relatively minor but important for certain buyers. The 50UA73006LA provides an extra USB port and newer Bluetooth 5.1 connectivity, while the 50UA74006LB features a slimmer design and slightly lower power consumption. Choosing between them largely comes down to connectivity preferences versus design and efficiency.

Verdict

For most buyers, the LG 50UA73006LA is the better overall choice thanks to its additional USB port, Bluetooth 5.1 support, and lighter build, making it more versatile for daily use. However, if you prefer a slimmer design with slightly better energy efficiency, the LG 50UA74006LB remains an attractive option. Since picture quality, gaming features, and smart TV capabilities are virtually identical, connectivity gives the 50UA73006LA a slight edge.
