HP EliteBook X G1a AMD Ryzen AI 9 HX PRO 375 Display Color Banding Fix Windows 11

Set Maximum Colour Depth

Open AMD Software: Adrenalin Edition → Display. Set the colour depth to the highest the EliteBook X G1a panel supports and the pixel format to RGB 4:4:4 Full. A limited range is a common cause of banding.

Update the AMD Driver

Install the latest AMD Radeon driver from HP Support for EliteBook X G1a. Driver updates improve gradient handling and dithering, which reduces visible banding on the built-in display.

Disable Contrast Enhancements

In AMD Software and any HP display utility, turn off vivid, contrast or vibrance enhancements. These stretch the tonal range and exaggerate banding on the EliteBook X G1a, so a neutral setting looks smoother.

Use the Correct ICC Profile

In Windows Color Management, set the factory ICC profile for the EliteBook X G1a as default. A stray profile can introduce banding, and the correct profile gives smooth, accurate gradients.

Why is there color banding on HP EliteBook X G1a?

Color banding on the HP EliteBook X G1a shows as visible steps in gradients instead of a smooth blend. It is usually caused by the display set to a lower color depth, an outdated graphics driver, or an aggressive dithering or contrast enhancement setting rather than a panel defect.

How do I fix color banding on EliteBook X G1a?

Set the display to its highest bit depth and full RGB range in the AMD graphics control panel, update the AMD Radeon driver from HP Support for EliteBook X G1a, disable contrast or vibrance enhancements, and use the correct ICC profile. Restart after the driver update.

Does the color depth setting cause banding on EliteBook X G1a?

Yes. If the output is set to a limited range or lower bit depth, gradients show banding. In AMD Software → Display, set the colour depth to the maximum the panel supports and the pixel format to RGB 4:4:4 Full to smooth gradients on the EliteBook X G1a.

Is banding worse in dark scenes on EliteBook X G1a?

Yes. Banding is most visible in dark gradients and shadow areas because the eye notices the steps more there. Correct colour depth, an updated driver and disabling contrast enhancements reduce it, and HDR content sometimes hides it better than SDR.
