If you’ve ever had the nagging feeling that your monitor isn’t delivering the crisp, smooth visuals it should, you’re not alone. Whether you’re gaming competitively, editing high-res video, or simply enjoying content online, your monitor’s performance can make or break the experience.
Monitors don’t just display images; they’re the interface between you and every pixel of your digital world. Refresh rate, frames per second (FPS), pixel integrity, and backlight quality all play critical roles. If one element underperforms—even slightly—it can cause headaches, eyestrain, and frustration you might not immediately attribute to your screen.
In this guide, I’m going to walk you through how to examine your monitor’s refresh rate, FPS performance, possible pixel defects, and backlight issues in ways that are quick, accurate, and satisfying. We’ll use a mix of browser tools, operating system settings, and gaming software so you can be confident in your monitor’s capabilities.
Section 1: How to Check Your Refresh Rate (Hz)
The refresh rate (measured in Hz) is how many times per second your display updates with new information. A higher refresh rate means a smoother visual flow, which is critical for fast-paced gaming and even for reducing eye fatigue when scrolling through content.
Method 1: The Easy Way (Use Our Tool)
The quickest way to check your refresh rate is to visit our Screen Refresh Rate Test. This browser-based tool detects the actual refresh rate your monitor is using right now.
Why this matters: operating systems or browsers occasionally default to lower rates (like 60Hz) even if your monitor is capable of more. This can happen after updates or with certain power-saving settings.
When you run the test, it samples the display’s frame timing in your browser and reports the real-time figure. If your monitor’s advertised refresh rate is 144 Hz144 Hz but you see 60 Hz60 Hz, you know it’s time to dig into your settings.
Method 2: In Windows 11/10
To check in Windows:
- Right-click anywhere on your desktop.
- Select Display settings.
- Scroll down and click Advanced display settings.
- Here you’ll see your current refresh rate in Hz.
If you find your monitor is running below its maximum capability, click Display adapter properties for Display 1, go to the Monitor tab, and select the correct rate from the dropdown list.
Tip: Ensure your monitor is connected with a cable that supports high refresh rates, like DisplayPort or high-quality HDMI. Lower-tier HDMI cables may cap your output.
Method 3: In macOS
On a Mac:
- Open System Settings.
- Go to Displays.
- Press the Option key while clicking on the Scaled button to reveal refresh rates.
Select the appropriate rate. Keep in mind, certain Macs (especially MacBooks with external monitors) might limit refresh rate based on resolution settings or even dock adapters.
Section 2: How to Test Your Frames Per Second (FPS)
Frames per second (FPS) measures how many images your system can produce per second during gameplay or video rendering. High FPS means smoother motion and better responsiveness, which is essential for competitive play.
Method 1: Browser FPS
Visit our FPS Test page to run a quick browser-based benchmark. This will show you how many frames per second your system and browser are capable of rendering under simple conditions.
FPS in browsers can differ from gaming FPS due to hardware acceleration, background processes, or browser-specific optimizations.
Method 2: In-Game Settings
Most modern games have a built-in FPS counter. Here’s how you typically enable it:
- Look under Graphics or Display Options in the game menu.
- Toggle Show FPS or similar.
In-game measurements are the most relevant for players, as they show the FPS during actual gameplay with all the visual effects and physics calculations active.
Method 3: Using Software (Steam, NVIDIA/AMD)
On Steam:
- Open Settings.
- Go to In-Game.
- Enable In-game FPS counter and choose where on the screen it should appear.
For NVIDIA GeForce Experience:
- Open the overlay (Default shortcut:
Alt+Z). - Go to Settings > HUD Layout > FPS Counter.
For AMD Radeon Software:
- Enable the Performance Overlay in settings.
Section 3: How to Check for Dead or Stuck Pixels
Pixels are tiny digital “dots” making up your screen’s image. If a pixel isn’t functioning correctly, it may appear as a black dot (dead pixel), a colored dot that never changes (stuck pixel), or an overly bright point (hot pixel).
Method 1: The Best Way (Use Our Tool)
Our Dead Pixel Test is straightforward: it displays full-screen solid colors so faulty pixels stand out. By cycling through red, green, blue, black, and white screens, you can see if any pixel fails to change as it should.
Method 2: What to Look For
- Dead Pixels: Permanent black spots regardless of image shown.
- Stuck Pixels: Always stuck on one color.
- Hot Pixels: Always lit brightly.
Some stuck pixels can be “revived” using pixel-fixing software or light pressure, but dead pixels are generally permanent.
Section 4: How to Test for Backlight Bleed & IPS Glow
Backlight bleed occurs when light escapes from the edges or corners of the monitor, especially visible during dark scenes.
IPS glow is a uniform glow across the screen when viewing dark content from certain angles—common in IPS panels.
To test:
- Visit our Backlight Bleed Test page.
- View the black screen in a dark room.
Note any uneven brightness along the edges. Slight bleed can be normal, but excessive bleed may be a reason for return or replacement.
FAQ
What’s the difference between Hz and FPS?
- Hz is how many times your monitor can refresh per second, while FPS is how many frames your computer outputs per second. If you have 144Hz but your PC only renders at 60FPS, you will only see 60 frames.
Why is my 144Hz monitor only running at 60Hz?
- Check your OS display settings, GPU output settings, and ensure your cable supports 144Hz.
Does a higher refresh rate matter for non-gamers?
- Yes. Even for office work or browsing, higher refresh rates can make scrolling smoother and reduce eye strain.
Final Thoughts
Your monitor is your window into every digital task, from everyday browsing to competitive esports. Knowing its true capabilities—and verifying they’re being fully utilized—means you’ll get the most out of your investment.
By regularly testing your refresh rate, FPS, pixel integrity, and backlight consistency, you can be sure you’re seeing every scene exactly as intended.
