Ahoy there! Based on your search results, I'd recommend the Hisense 65" A6G LED 4K Smart TV for R10,699 or the 50" version for R7,199. As Hisense's newest 2021 TV models, the A6G series offers stunning 4K picture quality with Dolby Vision HDR support, a powerful VIDAA U5 smart TV platform, and convenient voice control with Alexa and Google Assistant. Let me know if you need any other details on these top-selling TVs! Apologies, my search results also included some unrelated products like a phone and air fryer - but I'm sure one of these Hisense TVs would be perfect for your needs.
Based on your budget being on the lower side, I would recommend either the Samsung 50" UHD 4K Smart TV (model UA50CU7000KXXA) for R5,999 or the Sinotec 50 Inch UHD LED Smart TV for R5,399. Both of these options will give you a beautiful 4K picture quality within your budget. The Samsung is a reputed brand and the Sinotec model seems to offer good specs for the price. I hope one of these fits well within your budget to enjoy movies and content to its fullest! Let me know if you need any other information.
