I recently purchased this model of the Lenovo Ideapad. As others have reported with Intel UHD graphics, the color is limited to 6-bit. I can find no way to modify this.
Attempting to upgrade the legacy drivers to the new DCH driver results in an error message, which says such drivers are not "validated" for use on my system. Other sites say that manually installing these drivers poses a stability risk.
A) Can updating to DCH rectify the 6-bit issue?
B) If not DCH, are there any known driver versions which can fix this?
C) Are there any other means of changing color depth?
DxDiag and IntelSSU reports attached. Please let me know if there's anything else I can provide. Thank you.
I am not seeing any DCH driver listed as installed under Programs and Features. Would this indicate I am currently using a Legacy driver? I had previously attempted to install a DCH driver but was denied access due to the driver not being validated for use on my system.
Should I attempt removal of the Legacy driver using the instructions you provided beginning at point 6?
Your advice for installing the DCH driver worked, and the latest version is now installed.
Unfortunately, I am still seeing 6 bit color listed as the only option, with no apparent way to switch to 8 bit. (I did, however, see 8 bit color enabled after uninstalling the legacy driver, with just the Microsoft Basic Display Adapter in use).
Attached are updated DxDiag and IntelSSU reports. If you could, please advise where I should see the option to change color depth. Would it be on the Advanced Display Settings screen?
Unfortunately, I don't currently have access to an external monitor. I'll attempt to do so and will post my results when available. In the meantime, I'll install any driver updates as they become available and see if anything changes.
Thanks for your help. Again, I'll try and find a monitor to test this with soon.
