In the interest of esports and fast-action gameplay in general, more attention than ever is being paid to refresh rates, even on laptops. As such, HP is upgrading its Omen 15 with a 240Hz display.

As of right now, the Omen 15 is the only gaming laptop in the world with a 240Hz panel, and that will likely the be the case when it starts shipping later this year. It's a 15.6-inch TN display with a 1920x1080 resolution, though 240Hz is still a tall order at that resolution.
