Latest DisplayLink drivers and DirectX fullscreen errors

This thread contains lots of issues on games now, some of which were bugs that have been fixed in more recent releases and some that still exist.

We are aware of problems with some games in full screen mode, but there is no easy fix for these. One of the main problems is that games tend to use the graphics hardware directly in full screen mode, bypassing Desktop Window Manager (DWM). However this means that they bypass the DisplayLink virtual graphics driver and get confused when they try to use the graphics hardware and find DisplayLink also using the primary graphics card to render additional screens.

This is only in full screen mode, as in windowed mode the game goes through DWM and should function correctly. This is why we recommend running games in windowed mode.

We'd be happy to work with game developers to find a solution to supporting games in full screen, but we cannot do this without the support of the game engine developers. If you are a developer who could help with this, please contact us through "Ask a Question" on our website, so we can start a dialogue.
