Is this TV good for gaming?

It has a game mode and low enough input lag for casual console play. It lacks HDMI 2.1 features like 4K at 120Hz and variable refresh rate, so it suits casual rather than competitive gaming.

Does it need a soundbar?

The built-in speakers are fine for news and casual shows. For movies or sports, a soundbar is a worthwhile add, and it works with Roku TV Ready soundbars through the eARC HDMI port.

What is the difference from TCL's 5-Series?

The 5-Series adds local dimming and QLED color, which gives deeper blacks and brighter HDR. The 4-Series is the simpler, lower-tier set for basic viewing.

Does it support AirPlay and voice assistants?

Yes. It supports AirPlay for casting from Apple devices and works with Siri, Alexa and Hey Google for voice control.

Can I use it with an antenna?

Yes. It has a built-in digital tuner and a Live TV Channel Guide for over-the-air channels.

How many HDMI ports does it have?

It has four HDMI inputs, one of which supports eARC for a soundbar or receiver.
