Hi there! For around R12,000 you have some great smart TV options. I'd recommend checking out the Hisense 65U6K or 65U6H - both are 65-inch 4K TVs with Quantum Dot technology for vibrant colours and detailed images. As an added bonus, the 65U6H comes with a sound bar for improved audio. The LG 65-inch Nano776 is also a top performer with its crisp Netflix picture quality and AI features. All three of these TVs would be a fantastic addition to your home theater. Let me know if you need any other details!
