2 displays work great with OS X but now Windows. It comes up but is unusable because of the lag. Any suggestions to fix this? Also, my mouse is glitching a lot in windows.
Hi JakeC1, please reinstall Parallels Tools using the instructions from this article.
Once Parallels Tools are reinstalled, right click on Windows Desktop -> choose Screen Resolution-> click Identify button, then make sure the recommended resolution is chosen.
