1) Windows version 1803 (OS Build 17134.1184)
2) Cannot find info on Cursor FX, but just purchased it on 04/10/20 and downloaded the software directly from your site (and downloaded/installed it again today - 04/16/20).
3) Monitor is set at 1920 x 1080; scaling automatically set at 100 - 500 and Text/apps size at 125%. Please that when I changed the size to 150%, the cursor gets larger. However, everything else gets larger, too (texts, browsers, applications, etc.) In this case the overall large size is not easy on the eyes. Unless you have another suggestion, I prefer to leave the setting at 125%.
