Technical Display & Performance Guides
Engineering-grade documentation on frame pacing, refresh rates, monitor panel physics, and calibration.
FPS vs Refresh Rate: Understanding the Difference Between Rendering and Presentation
Frames Per Second (FPS) measures how fast your GPU produces frames, while Refresh Rate (Hz) measures how often your monitor updates its screen.
What Is Frame Time? Why Milliseconds Matter More Than Average FPS
Why average FPS masks jarring micro-stutters, how millisecond frame time reveals true smoothness, and how to interpret 1% lows.
What Is Frame Pacing? The Physics of Smooth Motion Delivery
Frame pacing describes the temporal regularity with which consecutive frames are presented to the screen. Even at high FPS, erratic intervals cause stutter.
What Is 1% Low FPS? How to Measure Gaming and Browser Stutter
1% low FPS calculates the average framerate of the slowest 1% of frames, pinpointing dips and hitches that average framerates hide.
Why Does FPS Stutter? Common Causes of PC and Browser Micro-Stutter
Identify the hardware, driver, shader compilation, and browser compositor causes behind sudden frame rate hitches.
Why Is My 144Hz Monitor Only Showing 60Hz? Troubleshooting Guide
A complete checklist to unlock 120Hz, 144Hz, 165Hz, or 240Hz on your gaming monitor across Windows, macOS, DisplayPort, and HDMI.
How to Test Monitor Ghosting: Understanding Response Times and Overshoot
Learn how to detect trailing trails, dark smearing on VA panels, and inverse ghosting from aggressive overdrive settings.
How to Check for Dead and Stuck Pixels on Your Monitor or Screen
How to clean your panel, cycle full-screen primary colors, distinguish dead from stuck pixels, and understand manufacturer ISO defect policies.
What Is Backlight Bleed? IPS Glow vs Edge Bleed vs Direct Uniformity
Distinguish mechanical frame bezel pressure backlight bleed from natural optical IPS glow, and learn how to evaluate dark-field uniformity.
What Is Monitor Gamma? Why Gamma 2.2 Is the Global Standard
How gamma curves compensate for human logarithmic brightness sensitivity, preserving shadow detail and midtone contrast.
What Is HDR on Monitors? Peak Brightness, Color Gamuts, and Bit Depth
What distinguishes real HDR (Mini-LED, OLED, 1000 nits) from fake entry-level HDR400 on standard edge-lit SDR monitors.
What Is PPI? Pixels Per Inch, Dot Pitch, and Display Sharpness Explained
Calculate exact screen pixel density, understand why a 27" 1440p monitor is sharper than a 24" 1080p screen, and find your optimal viewing distance.
