Hi, i have banding on intel 630 on my laptop screen. Display should be decent enough to show banding test without banding, I am using old version of driver because when i use usb-c to hdmi converter i get washed out colors on my external monitor, but old driver doesn't suffer from this. I suspect the problem is that driver doesn't allow to set quantization range or something else.
Thank you for joining the community.
Could you provide me with a video of the banding test that you are running on the system?
Here's video of the issue and photo of the end result. It's bit hard to see in the video but it sort of adjusts to final banding after you open the image or move it by scrolling.
Thank you for your response.
Please try to update the graphics driver with the driver version provided by the Lenovo to your system (https://pcsupport.lenovo.com/cr/en/products/laptops-and-netbooks/yoga-series/yoga-720-15ikb/download... https://pcsupport.lenovo.com/cr/en/products/laptops-and-netbooks/yoga-series/yoga-720-15ikb/download...) once the drivers are downloaded, I would recommend performing a clean installation of the graphics driver.
Please follow the steps below to uninstall the graphics driver:
Note: complete the Uninstall/install of the driver with the system out of internet connection to avoid any automatic update.
Does the issue happen if you use a different video connection ( HDMI® to HDMI®, DP to DP, USB-C to DP)?
I have had that driver, but I would be just trading banding on internal screen, to having washed out colors on external one. Only usb-c is available, no HDMI, or DP.

Thank you for the information.
Have you tested the Quantization configuration on the system, advice to complete the configuration without the external display connected, once the configuration is completed test the system behavior
By the way, please let me know the model of the display that you are using.
Hope this help.
setting is not available on this driver neither without or with external monitor plugged in. When I had newer drivers I also tweaked the video range when on usb-c to hdmi with unsatisfactory results in terms of colors. This thread has similiar results

Also this week after unplugging external monitor, internal monitor didn't have banding on test, but so far I haven't been able to replicate that.
Thank you for the information.
Please provide me with a video example of both displays behavior and step by step to replicate the system behavior/issue.
