Workaround to fix resolution issues when playing retro games.
Users with new systems running Windows® 10 are unable to play old games at full resolution. For example, users report that the right side of the screen could be missing when playing Heroes of Might and Magic 3 or Diablo 1.
Switch the screen resolution to 800x600 on the Control Panel for Intel® Graphics or in Intel® Graphics Command Center (depending on what your system has) and select any Scale Full Screen option available.
