"I believe the screen resolution mismatch is what is causing the issue"
So do I.
Open the Screen Resolution by clicking the Start button, click on Control Panel and then under Appearance and Personalization, click on Adjust screen resolution.
Select the monitor for which you want to change the screen resolution under “Display” drop down menu.
Then select the recommended screen resolution under “Resolution” drop down menu.
Then select “Duplicate these displays” under “Multiple displays” drop down menu.
