About the HP OMEN 40L

Best for: gaming use across both laptop and desktop form factors

The HP OMEN 40L is HP's dedicated gaming line (laptop and desktop) — high-refresh displays, dedicated gaming GPUs, and HP's gaming-focused cooling and software (Omen Gaming Hub).

Key features

  • High-refresh-rate displays standard across the gaming-focused configurations.
  • Dedicated discrete GPU in every configuration — distinct from HP's general-purpose lines where integrated graphics are common.
  • Omen Gaming Hub software for performance/thermal tuning — worth checking before assuming a hardware-level performance issue.
  • More aggressive cooling than HP's non-gaming lines, given the higher-TDP components.
