CS2 Monitor Refresh Rate: What 144 Hz, 240 Hz and 360 Hz Mean
Understand monitor refresh rate, check your selected mode and avoid oversimplified CS2 hardware advice.
A 240 Hz display does not guarantee that you are playing at 240 FPS. It also does not guarantee a specific end-to-end mouse-to-photon delay. First make sure you understand the two systems you are comparing: the display refreshing and the game producing frames.
Calculate the timing
At a nominal 144 Hz, the refresh interval is about 6.94 ms; at 240 Hz, about 4.17 ms; at 360 Hz, about 2.78 ms. These values are just 1,000 divided by the refresh rate.
The numbers do not include pixel response, processing, synchronization or frame-time variability. They are useful for describing capacity, not for proving which monitor a player should buy.
- 144 Hz → roughly 6.94 ms.
- 240 Hz → roughly 4.17 ms.
- 360 Hz → roughly 2.78 ms.
Check the active mode
In your operating system’s display settings, verify the refresh mode actually selected for your monitor. A panel capable of 240 Hz may be operating at a lower setting.
If your game changes resolution or display mode, verify the effective setting in the game as well. Refresh settings can vary by display path, cable, GPU and mode availability.
- Document the old setting before changing it.
- Compare motion in the same scene after adjusting settings.
Prioritize measurements over slogans
An upgrade may be valuable for some setups, but not everyone benefits equally from a higher headline refresh rate. Frame pacing, actual game FPS, input devices and usage patterns all matter.
Use the calculator for intervals and then assess your existing screen under repeatable conditions. Do not assume that buying a new display fixes packet loss or local stutter.
- Avoid benchmark claims without tested evidence.
- Consider return policies and compatibility before making purchases.
Example: 240 Hz hardware running in 144 Hz mode
Suppose the monitor model advertises 240 Hz, but the active operating-system display mode reads 144 Hz. The correct first action is to check available display modes, cables and connection capabilities—not to shop for a replacement immediately.
Once the actual mode is verified, compare it with average FPS and the variability of frame delivery. A 240 Hz interval is roughly 4.17 ms, but that does not mean every frame will be shown exactly 4.17 ms after a mouse click. The rendering, buffering and display pipeline still matter.
