Dell doesn't supply Windows 10 drivers for the Intel HD Graphics 5500 in the XPS13, only for Windows 8.1.
I'm seeing a similar issue with an Inspiron 14R after a Windows 10 upgrade. Trying to determine if it's the same issue being chased here. I see flickering and I also have gotten vertical lines on the screen. I have the latest video drivers also. One thing I've noticed that isn't mentioned is that I only see this when running on battery power. If the AC is connected, video is rock solid. Is this symptom consistent with the issue being discussed here? I beginning to suspect that my issue may be power management related.
I think you can assume we have all tried uninstalling and reinstalling the drivers.
This does not help.
Please, forget 1st line support questions and elevate this issue to 3rd line support.
For me, the issue is present regardless of being on mains or battery.
It may, however, be related to power and therefore affects your model differently to ours.
tried both upgrading/uninstalling video drivers, running DELL driver update tool, which updated BIOS and chipset drivers.
Results are all the same: screen keeps flickering.
Hope it is not hardware issue and it won't be necessary to replace my laptop =(
For all those suffering with this flickering problem on the XPS 13 after upgrading to Windows 10:
With the help of Dell technical support, I have found a work-around that has, thus far, completely eliminated the flickering problem. You need to change a BIOS setting:
This has completely stopped the flickering problem for me. However, I consider this a work-around only (not a fix), as C-States are used by Windows to better manage power and I suspect there will be side-effects of turning this off (such as reduced battery efficiency). But, it's a big improvement until there's a fix.
For the record, I am still using the graphics driver that was installed with Windows 10 (version 10.18.15.4256).
If you try this change, please post back to let the rest of the community know if it works.
DELL-RAVI BC: Please do your homework. The Intel link that you posted installs the same version of the display driver that we all already got when we upgraded to Windows 10 (10.18.15.4256). I know the entire package has a different version number from Intel (22.214.171.124.4256), but if you look at the package contents you'll see that it includes the same version of the driver we already have.
