Balancing screen size with the right resolution is essential for an enhanced viewing experience. Larger screens generally benefit from higher resolutions, as a greater pixel density ensures sharper images and crisper text, minimizing the visibility of individual pixels.
Refresh rate
The refresh rate (measured in Hz) determines how many times the screen updates per second. The most common refresh rates for monitors are 60Hz, 120Hz, 144Hz, and 240Hz. A higher refresh rate leads to smoother motion, which is especially beneficial for gaming and fast-paced applications.
Refresh rate recommendations for different use cases
- Casual & professional use: Refresh rate of 60Hz is ideal for general tasks like web browsing, document editing, and video streaming, where higher refresh rates offer minimal benefits. Designers and video editors benefit from 60Hz or higher refresh rate for smooth playback, though colour accuracy and panel quality are often more critical than refresh rate.
- Gaming: For smoother gameplay by reducing motion blur and screen tearing, a refresh rate of 120Hz or 144Hz is especially useful for fast-paced action games and first-person shooters.
- esports & competitive gaming: High refresh rates of 240Hz+ minimize input lag and ensure ultra-fluid motion, giving players a competitive edge.
Response time
Measured in milliseconds, response time affects how quickly pixels change colours, impacting motion clarity and reducing ghosting. A low response time is crucial for gaming because it ensures that pixels can transition quickly and accurately without blurring or ghosting, which is essential for maintaining clarity in fast-paced action scenes.
- 1ms – 5ms: Best for gaming, as it ensures fast pixel transitions and minimal motion blur. Action scenes and fast-moving visuals appear smooth and crisp. Even slight delays can affect a player’s ability to react swiftly, making low response times particularly important for first-person shooters and racing games.
- 5ms – 10ms: Suitable for general use, video streaming, and casual gaming. While not as fast as lower response times, it still provides a comfortable experience for non-competitive gameplay and standard applications.
Panel type (IPS, TN, VA, OLED)
Panel type significantly impacts colour accuracy, contrast, and response times, affecting how visuals appear on-screen. Here are some of the main panel types:
- IPS (In-Plane Switching): Offering the best colour accuracy and wide viewing angles, it’s best for content creators and professionals who need precise colour reproduction for design, photography, and video editing.
- TN (Twisted Nematic): It provides the fastest response times, great for competitive gaming where reaction speed matters most. However, it has weaker colour reproduction and limited viewing angles.
- VA (Vertical Alignment): Delivering excellent contrast ratios and deep blacks, it’s a solid choice for movie watching and general entertainment. It offers better colour accuracy than TN panels but can have slightly slower response times.
- OLED (Organic Light-Emitting Diode): It offers the best picture quality with perfect blacks and vibrant colours, ideal for high-end gaming and cinematic experiences. However, it is expensive and susceptible to burn-in over time.
Brightness and contrast ratio
When selecting a monitor, both brightness and contrast ratio play essential roles in the overall viewing experience.
Brightness
Brightness is measured in nits, which quantifies how much light a monitor can emit. The perfect brightness levels largely depend on the ambient light conditions of your environment, affecting your viewing comfort and visibility.
