The Ultimate Guide to FPS, Refresh Rate (Hz), and Monitor Performance
In the high-octane world of PC gaming and content creation, your hardware's performance is the line between victory and defeat. While a powerful Graphics Card (GPU) is essential, your monitor's ability to display those frames is equally critical. Welcome to Xizoa Hub's Professional FPS Monitor, the most advanced online utility designed for gamers, developers, and hardware enthusiasts. Whether you are optimizing your PC for high-end gaming or testing your smartphone's display capabilities, accurate data is the first step toward performance.
FPS vs. Hz: Understanding the Difference
One of the most common misconceptions in the gaming community is treating FPS (Frames Per Second) and Hz (Hertz) as the same metric. While they work together to produce the image you see, they originate from different sources.
1. What is FPS (Frames Per Second)?
FPS is a measure of performance generated by your CPU (Processor) and GPU (Graphics Card). It represents how many unique images your system can render and output every second.
- Low FPS (< 30): The video will look choppy, like a slideshow. Unplayable for shooters.
- Standard FPS (30-60): The standard for console gaming and movies. Acceptable for RPGs.
- High FPS (60-144+): The gold standard for PC gaming. Animations are fluid, and inputs feel snappy.
2. What is Hz (Refresh Rate)?
Hz is a hardware limit of your Monitor or Phone Screen. It represents how many times per second the screen can physically update the pixels.
- 60Hz: Standard office monitors. Refreshes 60 times a second.
- 144Hz / 240Hz / 360Hz: Dedicated Esports monitors designed for CS:GO, Valorant, and Overwatch.
What is Screen Ghosting?
Have you ever moved your mouse quickly or turned your camera in a game, only to see a blurry trail behind objects? This phenomenon is called Ghosting. It occurs when the pixels on your LCD/OLED panel cannot change colors fast enough to keep up with the moving image (Pixel Response Time).
Use our Motion Blur Test above. Slide the speed to maximum. If the UFO looks sharp, your monitor is fast (1ms GtG). If it smears, you have ghosting.
Optimization Guide: How to Boost FPS?
- Enable Hardware Acceleration: Ensure your browser settings allow GPU usage.
- Manage V-Sync: Turn V-Sync OFF for competitive games to reduce input lag, but turn it ON for story games to stop screen tearing.
- Thermal Throttling: If FPS drops after 10 minutes, clean your PC's dust filters.
Advanced Sync Technologies: G-Sync & FreeSync
Modern gaming monitors come with Variable Refresh Rate (VRR) technologies. Nvidia's G-Sync and AMD's FreeSync allow the monitor to adjust its Hz dynamically to match the GPU's FPS. This eliminates screen tearing without the input lag penalty of V-Sync.
To test if your G-Sync is working, run this test. If the FPS fluctuates but the motion remains tear-free, your VRR is active.
Mobile Displays: 90Hz and 120Hz ProMotion
Smartphones have evolved. Most flagships now feature high refresh rate screens. However, to save battery, they often throttle down to 60Hz when not touching the screen. Use this tool on your mobile browser to see if your phone maintains 120Hz during static web browsing or scrolling.
