Does Your Monitor Match Your PC? The Hz vs FPS Trap

A monitor can only show frames your PC actually renders — so a 360 Hz panel does nothing extra if your game caps at 240 fps. Before you buy refresh rate, find out how many frames your rig sustains in the game you play. Then match the panel to that number, and spend the difference on the spec the box buries: real grey-to-grey response.

Refresh rate (Hz) is how many times per second the screen can update. Frame rate (FPS) is how many your PC actually produces. The screen can only display what it's fed — so if your game runs at 200 fps, a 360 Hz monitor shows 200 unique frames and repeats the rest. The extra 160 Hz buys you nothing until your FPS rises to meet it.

The competitive titles people buy fast monitors for — CS2, Valorant — are usually CPU-bound: your processor, not your graphics card, sets the frame ceiling, and turning settings down won't raise it much. A heavier, GPU-bound game (a modern AAA shooter) responds to lower settings and a stronger GPU instead.

• Check first: turn on your in-game FPS counter and play a real, busy round — a smoke-filled site, a team fight. Note the low, not the menu number.
• Then match: buy a refresh rate at or a little above that sustained low. A 240 Hz panel for a rig that holds ~240 fps is well-matched; 360 Hz is wasted on it.
• Upgrade order: if you're CPU-bound and want more frames, the CPU is the upgrade — not the monitor.

Even when your FPS can feed it, the gains shrink. The big, replicated jump in aim-task performance is from 60 to 144 Hz. 144 to 240 buys a smaller, still-real improvement. Past 240, the evidence thins fast — 360 and 480 Hz are for the few who both sustain those frames and compete at a level where a marginal edge is worth the spend.

Two 240 Hz monitors can look very different in motion, because refresh is only half the story — pixel response time (GtG) is the other half, and it's the spec the box downplays. A slow panel smears behind a fast flick even at a high refresh. OLED effectively wins this outright (~0.03 ms); a good IPS or TN is close; a slow VA smears. Once two panels share a refresh rate, response is what actually separates them — which is exactly what our measured panel composite weighs.
