A 1000Hz monitor can refresh its image up to 1,000 times per second—one refresh every millisecond. That is the display’s update capacity, not a promise that your PC or game will produce 1,000 distinct frames per second. Can you see the difference? It may depend on the task and viewing conditions, but the evidence cited here does not test 1000Hz against lower monitor rates.
What does a 1000Hz monitor refresh rate mean?
Hertz (Hz) measures how often a display can update its image. At 1000Hz, the nominal interval between refreshes is 1 millisecond. The figure describes the monitor’s refresh capacity; it does not tell you how many new images your game is rendering.
Refresh rate is not frame rate
Refresh rate is the display’s update frequency. Frame rate, measured in frames per second (FPS), is how many frames the computer or game produces. A 1000Hz screen cannot show 1,000 distinct new game frames each second if the system produces fewer. The two rates interact, but they are not interchangeable.

Latency is the delay across the game, input device, computer, and display. A faster refresh cycle can affect some display timing, but the Hz rating alone is not an end-to-end latency measurement. Actual responsiveness also depends on frame delivery and the rest of the system.

Can you see the difference?
Sometimes, but there is no universal “eye limit” that answers the question for every person and task. Perception depends on factors such as the motion or visual pattern being viewed, how frames arrive, and the display’s behavior. Evidence that higher rates can matter in particular tasks does not establish that every viewer will notice a practical improvement at 1000Hz.
What a gamer study found—and did not test
A study by Adam J. Toth and colleagues, published June 1, 2026, tested 101 FPS gamers at 60Hz, 144Hz, and 360Hz—not 1000Hz. Participants reliably distinguished larger tested differences, such as 60Hz versus 360Hz, but did not reliably distinguish 144Hz from 360Hz after adjustment for response bias. In the target-acquisition task, performance improved when moving up from 60Hz, while the difference between 144Hz and 360Hz was not statistically significant. The authors suggest gains may be marginal beyond 144Hz for that task; this result cannot establish what happens at 1000Hz. NVIDIA Research study.

Motion tasks and visual artifacts are different questions
A 2016 study by Sihem Kime and colleagues found better performance at high frame rates than at 60Hz for its tested tasks, which included speed discrimination, spatial discrimination, and reading with moving stimuli. It supports the narrower point that temporal resolution can matter for motion-related tasks; it does not identify a universal optimum or a 1000Hz threshold. Optica Publishing Group paper.
Davis, Hsieh, and Lee reported in 2015 that earlier conventional critical-flicker studies discussed maximum observable rates around 50–90Hz under their stated conditions. Their own experiment found visual flicker artifacts above 500Hz when high-frequency spatial edges were present. This is a specific laboratory result, not evidence that every person will see flicker—or gain a practical gaming advantage—from an ordinary 1000Hz monitor. It shows why a single number cannot define the limit of vision. Scientific Reports paper.

The U.S. Department of Energy explains that temporal light modulation can produce direct flicker, stroboscopic effects when objects move through modulated light, and phantom-array patterns associated with rapid eye movements. Effects can be visible at high frequencies under some relative-motion conditions, and responses vary among individuals. This is lighting context, not a direct test of monitor refresh rates. DOE overview of temporal light artifacts.
Does a higher refresh rate mean higher FPS?
No. A higher refresh rate raises the display’s potential update frequency, while FPS depends on what the game and computer render. If the system is producing fewer frames than the monitor can refresh, the monitor does not create the missing game frames. To judge a setup, consider the frame rate and its consistency in the games you play, rather than treating the monitor’s maximum Hz as the computer’s FPS.

Is a 1000Hz monitor worth it?
The available evidence here does not establish that 1000Hz provides a measurable advantage over lower refresh rates in ordinary gaming. The 2026 gamer study stopped at 360Hz, and the other cited findings examine specific motion or visual conditions rather than 1000Hz gaming monitors. Whether the extra capacity matters to you depends on your use and on the finished display’s behavior; the headline Hz figure alone cannot settle that.

- Native versus dual-mode rate: Check whether the advertised maximum is native or requires switching resolution or display mode.
- Resolution and image quality: Compare the picture at the refresh rate you would actually use.
- Frame delivery: Consider the FPS your computer can sustain in your games and how consistent its frame times are.
- End-to-end responsiveness: For competitive play, assess system and input latency rather than assuming the refresh rate represents total delay.
- Motion behavior: Look for measured motion clarity, pixel response, overshoot, and any blur-reduction behavior.
- Other practical factors: Check adaptive-sync behavior, warranty, and price in your region.

A real 1000Hz monitor: LG UltraGear 25G590B
On May 19, 2026, LG announced the UltraGear 25G590B, a 24.5-inch, 1920 × 1080 IPS monitor that LG describes as a native 1000Hz Full HD display. LG said launch in select markets was expected in the second half of 2026, with additional markets to follow; that announcement does not establish current local availability. LG describes the monitor as intended for competitive FPS gaming and claims benefits for motion clarity, tracking, and response. Those are manufacturer claims, not independent test results. LG’s announcement.
LG called it the “world’s first native 1000Hz FHD gaming monitor” among products introduced by consumer-electronics brands, based on publicly available information as of its May 19, 2026 announcement. That qualification matters: the claim is LG’s, not an independent finding. The cited evidence does not establish retail pricing, current stock, or measured performance of a finished retail unit.
