What are you seeing?

Wrong color or resolution, flickering, low refresh rate and any other graphics related issue when using a video cable adapters, a splitter and/or a docking station to attach a monitor to a computer or to a laptop that has not been manufactured by Intel.


Environment:

Intel® HD Graphics (all generations)


How to fix it:

Intel does not recommend the use of any kind of adapters. This is because we cannot test all of them, so we cannot guarantee that these are going to work.

The best solution is doing a direct connection with a single cable that has the same connection type in both ends.

If you are unable to use a straight connection, a possible solution is updating the graphics driver to the latest version. You can contact your system manufacturer to see if there is a graphics driver update available for your system model.

As an additional workaround, you can install all Windows* updates and update the BIOS with the assistance of your computer manufacturer.

In some cases, this issue has been fixed by installing the latest generic graphics driver released by Intel. You will need to keep in mind that Intel only releases generic drivers, so we cannot guarantee that our latest driver will work as expected, and it is very possible that it will remove features added only to the driver developed by your system manufacturer.

If none of these workarounds fixes the issue, it is very likely that the adapter is not supported by the controller. In that case, you contact the adapter manufacturer to look for possible workarounds.
