banding and/or washed out colors.

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:
  1. On the keyboard, press WinLogo key + R, then type in devmgmt.msc
  2. Expand the Display Adapters section.
  3. Find the Intel® Graphics Driver. The driver can also be called the Intel® Graphics Media Accelerator Driver (Intel® GMA Driver).
  4. Right-click the Intel Graphics Driver and select Uninstall.
  5. Select the checkbox Delete the driver software for this device.
  6. Do not reboot the system
  7. Find the NVIDIA® graphics driver
  8. Right-click the NVIDIA® graphics Driver and select Uninstall.
  9. Select the checkbox Delete the driver software for this device.
  10. Reboot the computer after the uninstall process has finished.
Once the reboot is completed install the graphics driver, first install the Intel® HD graphics driver, restore the system, and complete the installation of the NVIDIA® 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)?

 

 

Best Regards,

 

Leonardo C.

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.

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

Display model: Chi Mei [Unknown Model: CMN15E8] N156HCE-EN1 CMN N156HCE-EN1

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.
