Disable & Enable MPO via the Windows Registry

There is a well known issue where GPU drivers are crashing with multi-monitor setups due to an interaction with Windows MPO and both Nvidia and AMD GPUs.

Until this bug is fixed, the only solution is to disable MPO via the Windows Registry.

Disable MPO

To apply the fix, simply run mpo_disable.reg and reboot your computer.

Enable MPO

To enable MPO again, simply run mpo_enable.reg and reboot your computer.

You can also find the fix on Nvidia's support article.
