Reversed screens are technically impossible with vorpX. If you have trouble converging (which might seem like reversed images to you), please check for the things below:
1. Check whether the DK2’s display orientation is set according to the instructions in the DK2 Setup guide that comes with vorpX.
2. Make sure that games are set to 1920×1080 for the DK2. Other resolutions will almost certainly cause convergence issues, as they are not displayed using the whole screen on the DK2.
3. Try do adjust your IPD (interpupillary distance) manually. This can be done on the display page of the vorpX ingame menu.
4. Lower the 3D-Strength parameter in the vorpX ingame menu.
