Hi, I am using Windows 10 on Lenovo M710S Thinkcenter. I connect it with two monitors
1. the Lenovo standard monitor that comes with the package. I hooked it using VGA to VGA
2 . LG Flatron W1941S monitor that i hooked it using Display Port to VGA converter.
Both Lenovo and LG monitor only has VGA slot
When the computer was booting, the computer detect both monitor. but when windows login interface come up, only one monitor is detected.
Both of the monitors works, cable is fine, i can use either of them but cannot use them both as multiple display
It is normal for the login screen to only appear on one monitor. You should be able to configure for multiple displays after logging in, however.
Have you tried the second monitor on the other DP port?
Hope this helps,
