Is 120Hz worth it on a 1080p TV?

Yes for sports and fast action, where the higher refresh rate reduces blur compared with 60Hz sets. For films and slow shows the difference is small, and some viewers prefer to turn motion smoothing off.

Does this TV have smart apps like Netflix?

No. It is a plain Full HD set without a built-in smart platform, so you need a streaming stick, box or console for apps.

Is Full HD enough on a 50-inch screen?

At normal living-room distances 1080p looks sharp on 50 inches. Up close, or next to a 4K set, you will notice less fine detail.

Can I use it for gaming?

It works for casual console gaming, and the 120Hz panel helps with fast motion. It lacks the low-latency game modes and 4K input that dedicated gaming TVs offer.

What connections does it have?

It offers the standard HDMI and USB inputs plus an aerial connection for broadcast TV. Check the exact port count before buying if you have several devices.
