I have a new Lenovo IdeaPad Pro 5 16IPH11, machine type 83SK, with an Intel Core Ultra 9 386H and the 16-inch OLED display.
Since shortly after purchase I have been experiencing intermittent coloured artefacts on the built-in display — mainly red, green and violet/pink outlines, speckles and bands. They are especially noticeable on photographs, textured areas, fine text and particular mid-tone brightness levels.
The problem is very intermittent. It may appear immediately after startup and then disappear completely after several minutes or hours without any intervention. On other days the laptop can run normally for long periods.
I have done a number of controlled tests:
• When the artefacts are visible on the Lenovo screen, the identical image displayed simultaneously on an external Samsung TV over HDMI is completely clean.
• Screenshot files that appear corrupted while viewed on the Lenovo are completely clean when transferred to another device.
• The BIOS screen appears clean.
• Lenovo’s built-in OLED colour self-test showed clean full-screen white, red, green and blue.
• Turning Intel Panel Self Refresh off made no difference.
• Turning Variable Refresh Rate off made no difference.
• Manually changing display brightness makes no difference.
• Intel Graphics Software currently reports graphics driver 32.0.101.8509.
The most revealing test was a custom grayscale diagnostic chart. The artefacts appear at specific tonal/luminance levels rather than fixed physical positions on the screen. For example, a strong red band appears around one part of the grey gradient, with additional faint green/red/violet artefacts at other tonal levels and on certain text strokes.
Even more interestingly, when Windows automatically dims the display before screen timeout, the coloured artefact band visibly moves across the grayscale gradient as the screen darkens. This suggests the fault may be linked to a particular luminance/gamma/display-processing threshold rather than damaged image files or fixed bad pixels.
Has anyone with an IdeaPad Pro 5 16IPH11 / 83SK, or another recent Lenovo OLED model, experienced anything similar?
If so, did you identify the cause — Intel graphics driver, HDR/colour management, gamma/LUT processing, OLED panel/TCON, eDP/internal display electronics, BIOS/firmware, or something else?
I would be particularly interested to hear from anyone who has reproduced this and found a reliable fix.
