Monitor Banding: What Causes It and How to Fix It

Monitor banding is when a smooth gradient, such as a sunset, a clear sky or a slow fade to black, shows visible stripes of color instead of one seamless blend. Most of the time it comes from the content itself or from a setting, not a faulty screen. Check the graphics card’s color depth and RGB range first, then the picture mode, dynamic contrast and cable. Only when all of those are clean is the panel the likely cause.

What monitor banding looks like

Banding is easiest to spot in large, gently changing areas of color. Instead of a smooth ramp, you see a series of flat bands with visible edges between them, a bit like the contour lines on a map. Common places to notice it:

• Blue skies and sunsets in games and photos.
• Dark scenes in films, where a shadow fades into black in clear rings.
• Desktop wallpapers with soft gradients.
• Fog, smoke and light glows around lamps in games.

A screen with 8 bits per color channel can show 256 levels per channel. That is normally enough for sRGB content, but as the Wikipedia entry on colour banding notes, the eye can still pick out neighboring levels across a wide, slow gradient. Anything that removes some of those levels makes the steps bigger and more obvious.

What causes banding on a monitor

Banding has many possible sources, and several can stack on top of each other. These are the usual suspects:

• 6-bit plus FRC panels. Many budget panels use 6 bits per channel and flicker between nearby shades, called frame rate control or temporal dithering, to fake the missing levels. It works well in bright tones and less well in dark ones.
• Compressed video and streaming. Video services squeeze files hard, and dark gradients are the first thing to suffer. This banding is baked into the content.
• Limited vs full RGB range mismatch. If the graphics card sends limited range (16 to 235) to a monitor expecting full range (0 to 255), or the other way around, levels are stretched or squashed, which causes banding as well as gray or crushed blacks.
• Low color depth or a compressed color format. A GPU output set to 6 bpc, or a YCbCr 4:2:2 or 4:2:0 format, reduces the information in the signal.
• Aggressive picture modes. Vivid, Game or Dynamic presets often boost contrast and saturation, which spreads the available levels further apart.
• Dynamic contrast. DCR keeps reshaping the tone curve as the scene changes, which can make gradients step and shift. Our DCR monitor guide explains what it does, and Acer’s adaptive contrast (ACM) setting works the same way.
• HDR tone mapping. Squeezing HDR content onto a modest HDR display, or showing SDR content in HDR mode, can create visible steps in highlights and shadows.
• Bad ICC profiles and software calibration. Correcting color or gamma in the driver or operating system reshapes an 8-bit signal and throws away levels, a point our PC monitor gamma guide covers in more detail.
• Cable bandwidth limits. At high resolutions and refresh rates, a cable or port that cannot carry the full signal may force the GPU to a lower bit depth.

Monitor banding or content banding?

Before you change anything, find out where the banding is coming from. A five-minute test saves a lot of guesswork.

Test a smooth gradient stored locally

Open a high-quality gradient test image saved on your own computer, not a streamed video or a compressed web image. A lossless PNG gradient from a reputable test pattern site works well. If the local gradient is smooth but a show or game still bands, the content is the cause. If the test image also bands, the issue is in your settings, cable or monitor. Our monitor color accuracy test guide lists free test patterns that include gradients.

Compare another device

Show the same file on a phone, laptop or second monitor. If every screen shows the same bands in the same places, the file is to blame. If only one monitor bands, focus on that monitor and the computer it is connected to.

How to fix monitor banding

Work through these in order and recheck the gradient after each one. The early steps fix the most cases.

1. Set full RGB range and color depth on the GPU

   On NVIDIA, open the NVIDIA app, go to System, then Display, choose your monitor and set Output dynamic range to Full and the highest Output color depth offered. In the classic Control Panel, which NVIDIA retired in May 2026, the same settings sit under Display, then Change resolution, once you choose “Use NVIDIA color settings”. On AMD Software, open Display and set Pixel Format to RGB 4:4:4 PC Standard (Full RGB) and Color Depth to the highest option. On Intel Graphics Command Center, open Display and set Quantization Range to Full.
2. Match the monitor's own range setting

   If the monitor menu has an RGB Range or HDMI Black Level option, set it to Full or Auto so it matches the graphics card.
3. Reset the picture mode

   Switch the monitor to Standard or sRGB, or run a factory reset of picture settings, to undo boosted contrast, sharpness and saturation.
4. Turn off dynamic contrast

   Disable DCR, ACM, Dynamic Contrast or Black Equalizer in the monitor menu and any similar enhancement in the graphics driver.
5. Remove software color tweaks

   Reset gamma, contrast and digital vibrance sliders in the driver to default, and temporarily switch to the default ICC profile to see if the banding disappears.
6. Check the cable and bandwidth

   Use a certified DisplayPort or high-speed HDMI cable, connect directly without adapters, and try a lower refresh rate to see if a higher color depth becomes available.
7. Update the graphics driver

   Install the latest driver from NVIDIA, AMD or Intel, then recheck the color settings, since driver updates sometimes reset them.

NVIDIA’s support page on deep color depth in Windows 11 confirms that the color depth options live under Display and Change resolution. AMD documents its color depth settings and notes that the choices available depend on the display and connection type.

Symptom, cause and fix at a glance

When banding is a panel limitation

If a local test gradient still shows steps after every setting is clean, the panel is probably the limit. Budget TN, VA and IPS monitors with 6-bit plus FRC panels tend to band in near-black tones, and some VA panels also show uneven dark gradients. Check the spec sheet for “16.7 million colors” (8-bit or 6-bit plus FRC) versus “1.07 billion colors” (10-bit or 8-bit plus FRC). The monitor’s manual or the manufacturer’s spec page sometimes lists the native bit depth.

You can reduce panel banding by keeping the signal clean, turning off enhancement features and making color adjustments in the monitor’s own menu rather than the driver. For color-critical work, a true 8-bit or 10-bit panel and hardware calibration make a visible difference, which our guide on how to calibrate a monitor explains.

Conclusion

Monitor banding is usually fixable. Confirm the problem with a local gradient, then set full RGB range and the highest color depth on the graphics card, reset the picture mode, turn off dynamic contrast, remove software color tweaks and check the cable. If faint steps remain only in dark gradients, the panel is the limit.
