2nd Display not reconized

2nd display Samsung SA200 using EVGA GeForce 640GT 2GB, 1st display shows low resolution and the 2nd display stays black and is not recognized. Also have a black border around the 1st screen. I need 2 screens running and I need high resolution. All worked
fine in 8.1

 

Duplicate display out of range with new monitor

Win10 HP desktop with onboard Intel GPU - 2 display ports and 1 vga. Been using two 23" 1080p monitors in duplicate display mode for months (main monitor display port, second monitor vga). Just replaced the vga monitor with a Samsung 32" using the same vga cable. Works great when set to extend mode @1080p. But when I choose duplicate mode, the new Samsung 32" monitor (vga) goes black saying out of range, display properties continue to say monitors are set to 1080p.

FYI: This is a secure/corporate machine, I cannot update drivers or OS due to group policy restrictions.

 

Cannot duplicate display to connected display port monitor

I have a Lenovo W530 with a second monitor connected via Display Port.

I can "project" and extend displays, however "Duplicate" does not work; it just extends the display.

Under Display settings, my laptop display is listed as 1|2 and the connected display port monitor as 3.

There is no option to "duplicate" display for 1 and 3. Any ideas?
