Fix a quarter of the screen TD2
Most likely in windows display settings you have a 150% screen scale.
Go to "Desctop" → "Right click on the Desctop" → "Display Setting"
In "Scale & Layout" → "Scale" select 125% or 149%(custom scale)
You should change scale of the screen to any other value like 125% or even custom 149%. Any scaling value that is comfortable for you.
Than please restart the computer or at least relogin the Windows user.
After that, open Time Doctor, start task tracking, go to https://2.timedoctor.com/screencasts and wait for the last screencast to appear, and make sure that the whole screen is visible there.
