Do I need more than 60Hz on a 4K monitor?

For pure office work, 60Hz is fine, but multiple reviewers and specialist-community posts note that 120Hz makes general desktop navigation noticeably smoother and is increasingly available at the same price as old 60Hz panels. Gamers will want 120Hz minimum, with 160Hz and dual-mode OLED options for fast-paced play. The jump from 60Hz to 120Hz is the one most reviewers describe as worth paying for.
