Why screen resolution becomes smaller when I disconnect RDP connection?

[whuang]

Hello support team,

I have several virtual machines running TC, and only one of the machines has this issue. When I launched TC and had it running with RDP connected and desktop displayed, the test was running fine and display resolution was correct (1679 x 907). However, if I keep TC running but disconnect the RDP, the display resolution seems got to smaller (1023 x 625). So it failed some of the test, because some of the objects collapsed when the window size shrinking. Below are 2 screenshots taken by TC on the same page with and without RDP connection. Does anyone know why it is happening and how to fix it?

You need to log in to the console of the remote machine and set the desktop resolution on the console.  This behavior you're seeing is normal because RDP connections set a different resolution than what is on the console.  So, when you disconnect and send the session back to the console, the resolution re-adjusts.
