Top 10 Best features to consider before buying a 4K TV: The majority of TVs today are 4K resolution, and as such there is a plethora of features to consider before buying. Cheaper TVs do not always address features that make the picture better, such as powerful image processors, local dimming for better contrast, brightness for better HDR (High Dynamic Range), and better quality sound. So just because a TV is 4K does not mean it is equal to others.

1. Resolution of the TV: The most important feature of a 4K TV is its resolution. It should have at least 3840 x 2160 pixels of resolution to deliver stunning detail. Older models had 1/4 of the resolutions called Full HD TVs at 1920 x 1080 pixels. A 4K TV has 8 megapixels of resolution vs. only 2 megapixels for an HD only TV. A 4K TV can upconvert HD to 4K to make the picture look better. This depends on the TVs processing power.

2. HDR (High Dynamic Range): HDR technology delivers better color accuracy and more vivid images than standard SDR (Standard Dynamic Range) TVs. With HDR, you will get lifelike colors and brighter highlights. The best HDR comes from TVs that can deliver a brighter picture (measured in nits). HDR can show the blackest blacks and whitest whites, with colors that pop.

3. Refresh Rate: The refresh rate on a 4K TV is measured in Hertz (Hz). A higher refresh rate means smoother motion and less blur in fast-moving scenes. A 120Hz or 240Hz refresh rate is ideal for high-action content like sports and video games. Many cheaper 4K TVs though are only 60Hz, so read the specs when choosing a TV if you need a higher refresh rate.

4. Smart TV Features: A smart TV allows you to access internet-based services like streaming apps, browsers, and social media platforms. This feature adds versatility to a 4K TV. Some TVs have their own proprietary operating system, while others use an android type system. Most now have voice command. Some TVs also have built in bluetooth to transmit video from your tablet or smartphone. Also look at the WiFi capabilities, as you want the most modern high speed Wifi.

5. Local dimming: This feature helps darken certain portions of the screen to make blacks deeper and whites brighter. Local dimming will also help to give you better HDR. The most advanced dimming is full array, which means the LEDs to illuminate the screen cover the whole back of the panel. Others use side lit and frame lit dimming.

6. Wide color gamut: A TV with a wide color gamut can display a broader range of colors, allowing for more accurate color reproduction.

7. Dolby Atmos: Dolby Atmos is an advanced sound technology that produces immersive, multidimensional sound. It places sound effects all around you and above you to create a more realistic and captivating experience. Also look for a TV with built-in Bluetooth, so you can send sound wirelessly to a soundbar and subwoofer for better sound. Sound Bars have bigger speakers than are built on the TV.

8. Voice Control: Some 4K TVs include voice control features to adjust settings, search for content, and launch apps. This feature can be convenient and make the TV more user-friendly. The sound feature will be built into the remote control usually.

9. HDMI 2.1 Inputs: HDMI 2.1 is a new VESA standard that allows for faster data transfer and higher resolutions up to 8K. It also supports lower latency for gaming. Your HDMI input is where you plug in your cable box, game stations, and blu-ray disc players.

10. High-quality sound: A good TV should have a built-in speaker or speakers that deliver clear and crisp sound quality. Some models include additional audio features like an AI sound pro to enhance the listening experience. You can also buy a sound system or sound bar to give your TV bigger speakers and more of them, including a subwoofer. But its nice when the built-in sound is sufficient to give you a decent sound experience.

In conclusion, a 4K TV with HDR, a high refresh rate, smart features, local dimming, wide color gamut, Dolby Atmos, voice control, HDMI 2.1, and high-quality sound can give you an immersive and enjoyable viewing experience. So, while purchasing a 4K TV, make sure it has all the necessary features to future-proof your investment and enjoy the content at its best.
