When I buy a new TV, what specifications should I pay close attention to and what can I ignore?
When purchasing a new TV, here are the important specifications to consider:

    Screen size: Determine the appropriate size based on the distance from the TV to your seating area and the size of your room.

    Resolution: Look for a TV with at least a Full HD (1920 x 1080) resolution or higher, such as 4K (3840 x 2160) or 8K (7680 x 4320).

    HDR: If you want a more vivid viewing experience, look for a TV that supports HDR (High Dynamic Range).

    Refresh rate: A higher refresh rate (measured in Hz) will result in smoother motion, so look for a TV with a refresh rate of at least 60Hz.

    Connectivity: Ensure that the TV has the necessary inputs for your devices, such as HDMI, USB, and Ethernet.

Specifications that you can generally ignore include:

    Smart TV features: These features can be duplicated by using a separate device, such as a streaming device or gaming console.

    Brand-specific technology: Features such as Motionflow or Auto Motion Plus are often just marketing terms used by specific brands and do not offer any significant improvement in picture quality.

    Speaker quality: The built-in speakers on most TVs are not very good, so you may want to invest in a separate sound system.

Overall, it's important to prioritize your specific needs and preferences when choosing a TV, as the most important specifications for one person may not be the same for another.
