LG UA75 50" 4K UHD Smart TV vs LG Nano 4K UHD AI NU70 Smart TV

Both are 50-inch 4K LG LED sets at 60 Hz, so the picture basics are close. The NU70 is the newer 2026 model with a Gen9 processor, Nano Detail Enhancer, HDR10 Pro and HLG, VRR, and webOS 26; the UA75 runs webOS 25 with the Gen8 processor, HDR10 only, and ALLM but no listed VRR. Owners rate the UA75 well at 4.3 from over 10,000 ratings, and LG's mid-range LED sets are generally reliable with good smart platforms. Buy the NU70 for the newer processing and gaming features; buy the UA75 if you want the model with the long track record of owner ratings.

• Choose the LG UA75 if you want the model with a large base of owner ratings and a proven webOS 25 setup for streaming and cloud gaming.
• Choose the LG NU70 if you want the newer 2026 processing, Nano Detail Enhancer, HDR10 Pro with HLG, and VRR for smoother gaming.
