I don't have specific information on the latest models, but I can provide general guidance on what features to consider when looking for the best 50-inch TV in India.

**1. ** Resolution: Look for a TV with at least 4K Ultra HD resolution (3840 x 2160 pixels) for a sharper and more detailed picture quality.

2. Display Technology: Choose between LED, OLED, or QLED based on your preferences and budget. LED TVs are more budget-friendly, while OLED and QLED offer better color reproduction and contrast.

3. HDR Support: High Dynamic Range (HDR) enhances the contrast and color range of the TV. Look for TVs that support popular HDR formats like HDR10 and Dolby Vision.

4. Refresh Rate: A higher refresh rate, such as 120Hz, ensures smoother motion handling, which is beneficial for gaming and fast-paced content.

5. Smart Features: Consider smart TVs with features like built-in Wi-Fi, app support (Netflix, Amazon Prime Video, etc.), and voice controls for a more versatile and convenient viewing experience.

6. Audio Quality: While external sound systems are always an option, TVs with good built-in audio can enhance your viewing experience. Look for models with Dolby Atmos or DTS:X support.

7. Connectivity: Ensure the TV has an adequate number of HDMI and USB ports to connect your devices like gaming consoles, Blu-ray players, or streaming devices.

8. Brand Reputation: Trusted brands like Samsung, LG, Sony, and Panasonic often provide better reliability and after-sales service.
