Lenovo Yoga 2 Pro is one of the best Windows Ultrabook convertible available right now in the market. However, the first batch of devices seems to be affecting with Yellow screen issues. The yellow pixels on the display turned out to be more of a blue/green shade of yellow instead of pure yellow. Lenovo forums had lots people complaining about the same and Lenovo quickly acknowledged the issue.
The Lenovo Yoga 2 Pro utilizes a Samsung LCD panel with a Pentile Red-Green-Blue-White (RGBW) pixel matrix, as opposed to a standard Red-Green-Blue (RGB) matrix on more conventional LCD panels. The Pentile matrix uses a modified physical layout of the pixels, taking advantage of white sub-pixels to deliver a brighter display at lower power consumption level.
A drawback of this modified matrix is a lower color luminance than a standard RGB matrix. This is most noticeable when viewing yellows. Some yellows may appear greenish in hue.
After two weeks, Lenovo has released an BIOS and Energy Manager update which will fix this issue.
An updated system BIOS has been released that, in conjunction with a new version of Lenovo Energy Manager, adjusts pixel and backlight intensity to optimize yellow performance, regardless of the selected power mode.
Both updates must be installed for the changes to take effect. It is recommended the BIOS update be installed prior to installing the updated Energy Manager.
