What Refresh Rate Do You Need? Choosing Between 60Hz, 144Hz, 165Hz and 240Hz+

“Should I just buy a 240Hz monitor?” becomes a much easier question once you know your main games and the frame rates your PC produces during actual play. High refresh rates are useful, but the largest number is not automatically the best match for your desk or budget.

Hz and FPS describe different things

Hertz describes how often the display refreshes each second. FPS describes the frames the system produces. The monitor, CPU and GPU all contribute to the experience. Buying a 240Hz screen does not turn a game running at 70 FPS into one rendered at 240 FPS.

Another way to compare refresh rates is the interval between refreshes. The following values use 1,000 divided by refresh rate. They are mathematical intervals, not measured total display latency.

Moving from 60Hz to 144Hz reduces that interval by about 9.72 ms. Moving from 144Hz to 165Hz reduces it by about 0.88 ms. The second change is not meaningless, but equal-looking increases in Hz do not produce equal reductions in time.

Let your main games shape the shortlist

For story-driven games, strategy titles and non-competitive play, balance motion with resolution and image quality. Consider 120–180Hz when the PC comfortably exceeds 60 FPS. A 60–100Hz display may still suit a particular budget or style of play. These are editorial starting points, not universal game requirements.

For competitive shooters, compare 144–180Hz options first, then consider 240Hz and above when your frame-rate evidence and budget justify the move. At 360Hz or higher, be clear about which game you are buying for and what you are willing to trade in resolution or other features.

The rest of your day matters, too. A monitor used for documents for hours and competitive games occasionally should not be chosen by the highest refresh rate alone.

Variable refresh matters when FPS moves around

Variable Refresh Rate, or VRR, lets the display adjust its refresh timing to incoming frames to help reduce tearing. FreeSync is one implementation, but check the operating range and compatibility of the actual display, GPU and connection.

A 165Hz monitor does not become pointless whenever a game drops below 165 FPS. A system running around 100–130 FPS can still justify a display above 60Hz. Check VRR and frame consistency rather than demanding a perfect FPS-to-Hz match every second.

A 1 ms label is not the whole motion story

Refresh rate and pixel transition time are different measurements. Response time is also not the complete delay between a mouse click and the resulting image. Check the conditions attached to a manufacturer's number and look for motion evidence at the mode you plan to use.

Try a familiar game with more than one overdrive setting instead of assuming the most aggressive-sounding mode is the right one. Let the visible result guide the choice.

Collect one useful play-session sample

Choose a scene with combat or detail representative of your normal sessions. Record resolution, graphics settings, average FPS and the sections where movement becomes uneven. A menu-screen frame counter is not a substitute for gameplay evidence.

Then compare two or three monitor candidates, giving your most-played game the greatest weight. After installation, check the selected refresh rate and confirm that the connection and cable support the intended mode before deciding whether the upgrade feels different.

Frequently asked questions

Is 165Hz a big step up from 144Hz?

The interval difference is approximately 0.88 ms. Compare panel behaviour, resolution, motion and price alongside the extra 21Hz rather than allowing that number to decide everything.

Can I buy a 240Hz monitor for a PC that produces 100 FPS?

You can consider it, but establish whether other features or a real upgrade plan justify the premium. “Future-proofing” should not be the only reason to pay more.

Is the interval table a measurement of input lag?

No. It is simply 1,000 divided by Hz. It does not include rendering time, display processing or pixel response.
