01.Introduction: Hertz Isn't Everything
Many gamers spend thousands on a 240Hz monitor, plug in an old HDMI cable, and play at 60Hz for years without realizing it. Worse, they enable "Extreme Overdrive" thinking they're gaining performance, but instead create "Inverse Ghosting" artifacts that actually hinder their aim.
In this guide, we'll calibrate your monitor using professional tools like TestUFO and engineering software like CRU to ensure every pixel transitions accurately and on time.
Don't do it Manually.

02.Chapter 1: The Basics Done Right (Real Hz)
The Golden Checklist
- Use the DisplayPort cable included in the box (older HDMI standards can limit your refresh rate).
- In Windows: Settings > System > Display > Advanced Display > Refresh rate. Ensure this is set to the maximum available value.
- On the Monitor (Physical Buttons): Disable "Eco Mode" or "Power Saving," as these can limit brightness and sometimes refresh rate.

If the site displays "60 fps" on your 144Hz monitor, something is incorrectly configured.
03.Chapter 2: Overdrive and Ghosting (Fine Tuning)
LCD monitors take time for pixels to transition colors (GtG - Gray to Gray). "Overdrive" applies extra voltage to speed this up.
Overdrive: Off
Significant blur (Ghosting). Trails follow moving objects.
Overdrive: Normal/Fast
The Sweet Spot. Good sharpness without visual artifacts.
Overdrive: Extreme
CAUTION. Causes "Inverse Ghosting" (Corona), where bright trails appear behind objects, hurting FPS accuracy.
Navigate your monitor's OSD and test options like "Trace Free," "Response Time," or "Overdrive" while watching TestUFO. Choose the one that sharpens the UFO without creating white ghost trails.
04.Chapter 3: Strobing (DyAc, ELMB, ULMB)
The secret weapon of pro CS2 players. The monitor strobes its backlight between frames to eliminate persistence of vision blur on your retina.
- BenQ: DyAc / DyAc+ (Market leading implementation).
- ASUS: ELMB (Extreme Low Motion Blur).
- Nvidia: ULMB 2 (Ultra Low Motion Blur).
The Verdict: ENABLE for competitive shooters like CS, Valorant, and R6. The screen will be slightly dimmer, but motion clarity becomes CRT-level. Disable for single-player games to avoid potential eye strain or headaches from PWM flickering.
05.Chapter 4: Panel Technologies (TN vs. IPS vs. OLED)
What is the real difference in 2026?
| Panel Type | Speed | Color Quality | Ideal Use |
|---|---|---|---|
| TN | Ultra Fast | Poor (Washed Out) | Strictly Pro CS2/Valorant |
| IPS | Very Fast | Excellent | Best All-Rounder |
| OLED | Instant (0.03ms) | Perfect (HDR) | The future (Premium cost) |
A1.Chapter 5: Monitor Overclocking (CRU)
Custom Resolution Utility (Hacking)
You can potentially push a 60Hz monitor to 75Hz, or a 144Hz model to 165Hz. This is generally safe—the monitor will simply display "Out of Range" if it can't handle the frequency.
- Download CRU (Custom Resolution Utility).
- Open it and select your active monitor.
- Under "Detailed Resolutions," click Edit.
- Increase the "Refresh Rate" in 5Hz increments (e.g., 60 -> 65 -> 70).
- Click OK and run the included "restart64.exe" to reload your display driver.
- Go to Windows display settings and attempt to apply the new refresh rate. If the screen goes black, wait 15 seconds for it to revert. If successful, you can try pushing higher.
Many 60Hz laptop panels can easily reach 90Hz using this method.
A2.Chapter 6: Color Calibration (ICC Profiles)
Downloading an ICC profile from sites like "Rtings" or "TFTCentral" for your specific model can correct factory temperature tints (too yellow or blue).
To install: Search for "Color Management" in Windows > Click Add > Select your .icm file > Set as Default Profile.
A3.Chapter 7: Cables and Bandwidth
Why prefer DisplayPort?
- HDMI 1.4: Maxes out at 144Hz @ 1080p.
- HDMI 2.0: Maxes out at 240Hz @ 1080p.
- DisplayPort 1.2/1.4: Supports official G-Sync (HDMI often only supports FreeSync, which can be less stable on Nvidia cards).
Always prioritize the DisplayPort port on your GPU.
A4.Chapter 8: Dual Monitor Setup (The Myth)
"Does mixing a 144Hz and a 60Hz monitor lag the system?"
In the past (older Windows 10 versions), yes—the DWM could throttle the faster monitor to 60Hz if animations were occurring on the slower screen.
In Windows 10 (20H2+) and Windows 11, this is solved via "Multiplane Overlay." You can mix refresh rates without issue today. Just ensure your games run in "Exclusive Fullscreen" or "Optimized Borderless" mode.
A5.Chapter 9: HDR on Windows
Unless you own a high-end OLED or Mini-LED monitor, DISABLE HDR.
Standard IPS/VA "HDR400" monitors lack the brightness and local dimming zones needed for a good experience. Enabling it often results in washed-out colors and gray blacks. A well-calibrated SDR image is superior to cheap HDR.
A6.Chapter 10: Care and Cleaning
Never use alcohol, Windex, or similar glass cleaners, as they destroy the monitor's anti-reflective coating forever.
The Right Way: Use a clean microfiber cloth and distilled (or filtered) water. Dampen—don't soak—the cloth and wipe gently, then finish with a dry microfiber cloth.
