How to Choose a 4K TV

Choosing a 4K TV requires evaluating display technology, size requirements, and feature compatibility with your content sources. The right TV balances picture quality, smart features, and connectivity for your specific setup.

1. Calculate the optimal screen size. Measure your viewing distance in inches and divide by 1.5 to get the recommended screen size. For a 10-foot viewing distance, choose a 75-80 inch TV. Ensure the TV fits your space with at least 2 inches clearance on all sides for ventilation.
2. Select the display technology. Choose OLED for perfect blacks and wide viewing angles in dark rooms. Select QLED or Mini-LED for bright rooms requiring higher peak brightness. Avoid basic LED TVs unless budget is the primary concern. Check local dimming zones — more zones mean better contrast control.
3. Verify HDR format support. Ensure the TV supports HDR10 and Dolby Vision for streaming services. Check that HDR works on all HDMI ports, not just specific ones. Look for peak brightness ratings above 600 nits for HDR10 and 1000 nits for optimal HDR performance.
4. Check gaming features. Look for HDMI 2.1 ports with 4K 120Hz support if you own a PlayStation 5 or Xbox Series X. Verify Variable Refresh Rate (VRR) and Auto Low Latency Mode (ALLM) support. Input lag should be under 20ms for responsive gaming.
5. Evaluate the smart TV platform. Choose TVs with Google TV, Roku TV, or webOS for the best app selection and update frequency. Avoid proprietary platforms from lesser-known brands. Ensure the platform supports all your streaming services and receives regular updates.
6. Assess audio capabilities. Check for Dolby Atmos passthrough if you plan to use a soundbar or receiver. Built-in speakers are adequate for casual viewing but consider the TV's audio output options. Look for eARC support on HDMI ports for high-quality audio return.
7. Compare connectivity and future-proofing. Ensure at least three HDMI 2.1 ports for multiple devices. Check for USB ports, Ethernet connection, and Wi-Fi 6 support. Verify the TV supports major streaming codecs like AV1 for future content compatibility.
