It sounds like you're referring to a 50-inch Smart 4K LED TV with a frameless design. Here are some details and features you might want to look for in a TV like this:

Key Features:

1. 50-Inch Display: A perfect mid-size option for medium to large rooms. It offers great viewing angles and is suitable for various types of content, from movies to gaming.

2. 4K Resolution: 3840 x 2160 pixels, providing crisp and clear images with high definition. This is perfect for streaming services, Blu-rays, and gaming consoles that support 4K.

3. Smart Features: The TV will have built-in Wi-Fi, allowing you to access streaming apps like Netflix, YouTube, Amazon Prime, Disney+, and many others directly. You can also control it with voice assistants like Google Assistant or Alexa, depending on the brand.

4. Frameless Design: A minimalist look with ultra-thin bezels, making the screen appear larger and more immersive. Frameless TVs have a sleek, modern aesthetic, adding to the overall decor of a room.

5. HDR (High Dynamic Range): Most 4K smart TVs support HDR, which enhances the color and contrast of images, providing a more dynamic picture with bright highlights and dark shadows.

6. Connectivity Options: Typically includes HDMI ports (possibly HDMI 2.1), USB ports, Bluetooth, and Ethernet, allowing you to connect gaming consoles, soundbars, and other devices.

7. Refresh Rate: A higher refresh rate, like 60Hz or 120Hz, can make motion smoother, especially for gaming and sports broadcasts.

8. Audio Quality: Many modern TVs are equipped with Dolby Atmos or DTS sound technology, though for an enhanced experience, you might want a separate soundbar or home theater system.
