If you play video games, display latency. Most modern TVs offer a way to reduce display latency, but it usually comes at the cost of various features or some impact to visual quality. Gaming monitors offer much better display latencies without compromising their listed capabilities.

Televisions are also more prone to updates that can break things and often have user hostile 'smart' software.

Still, televisions can make a decent monitor and are definitely cheaper per inch.
