The 120Hz refresh rate on the Samsung Galaxy S25 Ultra can contribute to reducing eye strain during long usage sessions, although the effect may vary among individuals.
Benefits of 120Hz Refresh Rate
1. Smoother Visual Experience: A higher refresh rate allows for smoother scrolling and transitions, which can make reading text and navigating through content more comfortable. This is particularly beneficial for activities that involve a lot of movement, such as gaming or scrolling through long web pages[2][9].
2. Reduced Motion Blur: The 120Hz display helps to minimize motion blur, making it easier to track moving objects on the screen. This clarity can reduce the effort your eyes need to exert, potentially leading to less fatigue during extended use[2][9].
3. Dynamic Adjustment: The Galaxy S25 Ultra can dynamically adjust its refresh rate based on the content being displayed. This means it can lower the refresh rate when showing static images or reading text, which can help conserve battery life while also reducing strain when high refresh rates are unnecessary[2].
Considerations
While many users report a more comfortable experience with higher refresh rates, there is no definitive scientific consensus that higher refresh rates universally reduce eye strain. Factors such as screen brightness, ambient lighting, and individual sensitivity also play significant roles in eye comfort[3][6]. Additionally, some users have reported experiencing eye strain even with high refresh rates, suggesting that personal preference and specific usage patterns are crucial in determining comfort levels[3][6].
In summary, while the 120Hz refresh rate on the S25 Ultra can enhance visual comfort and potentially reduce eye strain for many users, individual experiences may vary based on various factors.
