Before You Start
1 Warm Up Your Monitor
Turn on your monitor and let it warm up for at least 30 minutes before calibrating. Cold monitors display colors differently than warmed-up ones. This is especially important for OLED and professional monitors.
2 Set Up Room Lighting
Calibrate in the lighting conditions you'll actually use the monitor in. For accurate calibration:
- - Dim overhead lights or use indirect lighting
- - Close blinds to eliminate window glare
- - Avoid calibrating in complete darkness (unless that's how you use it)
3 Reset to Factory Defaults
Find the "Factory Reset" or "Reset" option in your monitor's OSD menu. This ensures you're starting from a known baseline rather than building on previous miscalibrations.
4 Set Native Resolution & Refresh Rate
Make sure you're running at your monitor's native resolution and desired refresh rate. Non-native resolutions can affect how colors and text render.
Windows: Right-click desktop > Display settings > Resolution & Refresh rate
5 Disable Automatic Settings
Turn off any automatic brightness/contrast features that might override your calibration:
- - Dynamic Contrast / DCR
- - Auto Brightness / Eco Mode
- - Ambient Light Sensor
- - Game modes with locked settings
Step 1: Calibrate Brightness
Brightness controls the luminance of black. Setting it too high makes blacks look gray; too low loses shadow detail.
Brightness Test Pattern
The boxes above show values 0, 1, 2, and 3 (out of 255). Ideally you should be able to barely distinguish box 2 and 3 from the background.
How to Adjust
- 1. View the test pattern above in fullscreen (or use our calibration tool)
- 2. Lower brightness until box 0 and the background are the same
- 3. You should barely see boxes 2 and 3 - if you can't, raise brightness slightly
- 4. For most rooms, this ends up being 20-40% brightness
Too High
Blacks look gray, washed out image, eye strain from excess light
Too Low
Lost shadow detail, can't see dark areas in games/movies
Step 2: Calibrate Contrast
Contrast controls the luminance of white. Setting it too high "clips" whites (loses detail in bright areas); too low makes the image look dull.
Contrast Test Pattern
The boxes show values 255, 254, 253, and 252. You should be able to distinguish all boxes from the white background.
How to Adjust
- 1. View the white test pattern above
- 2. Increase contrast until boxes 254, 253, 252 become indistinguishable from 255
- 3. Then reduce contrast until you can just barely see box 254
- 4. Most monitors perform well at 70-85% contrast
Note on VA Panels
VA panels often have excellent native contrast. If your monitor came factory set at 50% contrast, it may already be optimal. Increasing contrast on VA panels can sometimes introduce color shift.
Step 3: Calibrate Gamma
Gamma controls the midtone brightness - how light or dark the image appears between black and white. Standard gamma is 2.2.
Gamma Test Pattern
1.8
2.0
2.2 (Target)
2.4
2.6
Most monitors have preset gamma modes. Select 2.2 for standard viewing. Lower values (2.0) look brighter/washed out; higher values (2.4) look darker/more contrasty.
| Gamma | Appearance | Best For |
|---|---|---|
| 1.8 | Very bright, washed out | Mac legacy, bright rooms |
| 2.0 | Bright midtones | Competitive gaming (see shadows) |
| 2.2 | Standard | General use, sRGB content |
| 2.4 | Dark, punchy | Movies in dark rooms, cinema |
| 2.6 | Very dark | Professional cinema grading |
NVIDIA/AMD Gamma Override
If your monitor lacks gamma presets, you can adjust gamma via NVIDIA Control Panel or AMD Software. Go to Display > Adjust desktop color settings and adjust the gamma slider.
Step 4: Color Temperature & White Point
Color temperature determines how warm (yellowish) or cool (bluish) whites appear. The standard for monitors is 6500K (D65), which matches daylight.
Color Temperature Scale
Warm (5000-5500K)
Yellowish whites, easier on eyes at night, reduces blue light
Neutral (6500K)
Standard D65 daylight, accurate colors, recommended for most use
Cool (7500K+)
Bluish whites, more "vivid" looking, common factory default in Asia
How to Set
- 1. In your monitor's OSD, look for "Color Temperature" or "White Point"
- 2. Select 6500K, "Normal", "D65", or "sRGB" mode
- 3. If only presets available: "Normal" or "Neutral" is usually closest to 6500K
- 4. Avoid "Cool" or "Blue" presets unless you have a specific need
Step 5: RGB Balance (Optional/Advanced)
If your monitor has individual R/G/B gain controls, you can fine-tune the white point. This is optional for most users but helpful if whites look tinted.
Gray Ramp Test
The gradient above should appear completely neutral with no color tint. If you see a color cast (pink, green, blue), you may need to adjust RGB gains.
Warning
RGB adjustments can be tricky without measurement tools. If unsure, leave at default. Incorrectly adjusted RGB can make colors worse than factory settings. For most users, selecting a color temperature preset is sufficient.
Gaming-Specific Settings
Gaming monitors often have additional settings that affect image quality and performance. Here's how to configure them:
Response Time / Overdrive
Controls how aggressively pixels transition. Higher = less ghosting but more overshoot artifacts.
- Recommended: Medium / Normal / Fast (not Fastest/Extreme)
- Avoid: Maximum overdrive causes inverse ghosting
- Test with: Our ghosting test tool
VRR / G-Sync / FreeSync
Variable refresh rate eliminates screen tearing. Should be enabled for gaming.
- Recommended: ON for gaming
- Note: VRR can affect color accuracy slightly on some monitors
- G-Sync Compatible: Enable in NVIDIA Control Panel even for FreeSync monitors
Black Equalizer / Shadow Boost
Raises shadow detail without affecting overall brightness. Useful for competitive games.
- Competitive gaming: Use moderately to see enemies in shadows
- Single-player/Movies: OFF for accurate image
- Warning: High values make image look washed out
Low Latency Mode / Game Mode
Reduces input lag by disabling post-processing.
- Recommended: ON for gaming (usually reduces 5-15ms lag)
- Note: May disable some image enhancement features
- Check: Some modes lock settings - disable if you need adjustability
HDR Settings
HDR uses different calibration. Enable Windows HDR and configure in-monitor HDR mode.
- Windows: Settings > Display > Use HDR = ON
- Monitor: Enable HDR mode (may be auto-detected)
- Games: Enable HDR in individual game settings
- Peak brightness: Set to maximum for best HDR
Windows Display Calibration
Windows has a built-in calibration wizard that can help fine-tune your display settings and create an ICC profile.
How to Access Windows Calibration
- 1. Press Windows + R
- 2. Type
dccwand press Enter - 3. Follow the wizard for gamma, brightness, contrast, and color balance
- 4. Save the calibration profile when finished
ClearType Text Tuner
Optimizes text rendering for your specific display. Important for text clarity.
- 1. Search "ClearType" in Windows Start menu
- 2. Click "Adjust ClearType text"
- 3. Follow the wizard, selecting the clearest text samples
Night Light Settings
Windows Night Light reduces blue light in the evening. Schedule it rather than using all day:
Settings > Display > Night light > Schedule: Sunset to sunrise

Frequently Asked Questions
Do I need a hardware calibrator to calibrate my monitor?
No, you can achieve good results with free software calibration for general use and gaming. Hardware calibrators (colorimeters) like the Datacolor SpyderX or Calibrite ColorChecker are only necessary for professional color-critical work like photo editing, video production, or print design where color accuracy is essential.
What is the best gamma setting for gaming?
For most gaming, gamma 2.2 is the standard and provides balanced dark/light detail. Some competitive gamers prefer slightly lower gamma (2.0-2.1) to see more detail in dark areas, though this can make the image look washed out. For HDR content, your monitor will use different gamma curves automatically.
How often should I calibrate my monitor?
For most users, calibrating once when you get the monitor and then every 6-12 months is sufficient. LCD monitors are quite stable and don't drift significantly. Professional users doing color-critical work may calibrate monthly. OLED monitors may need more frequent calibration as organic compounds age differently.
What brightness should I set my monitor to?
Monitor brightness should match your room lighting. For a bright office: 250-350 nits (60-80% on most monitors). For a dimly lit room: 80-120 nits (20-30%). The goal is that a white page on screen should look similar in brightness to a white paper held next to the monitor.
Should I use sRGB mode or native color gamut?
For most content (web, games, videos), sRGB mode ensures colors display as intended since most content is created in sRGB. Use native/wide gamut only for HDR content or if you're creating content for wide gamut displays. Overly saturated native mode can make colors look unnatural.
