Checking Screen Resolution
Sandbox are not used to work as a normal user environment, so most of the time the screen resolution stay at the minimum 800x600 or lower. No one is actually working on a such small screen. Malware could potentially detect the screen resolution to determine if it’s a user machine or a sandbox.
