Hi,

Long story short: bought new PC with Manli GTX 1660 Super Gallardo (it has 1x DisplayPort, 1x HDMI and 1x DVI-D), can't use my working monitor (I made sure it still works) with a VGA to DisplayPort adapter. Need some help with finding a solution.

Already tried to reinstall drivers. Unplugged the monitor for an amount of time as suggested in multiple forums (this is supposed to reset something for whatever reason).
The 2 monitors worked perfectly fine together under windows 10 and 7 with a GTX 570 and a Radeon HD5770, the setup I used with both was: BenQ using HDMI and LL 3190T with a VGA to DVI-A adapter.

The LL 3190T also does work with the GTX 1660 Super but only if I unplug the BenQ monitor. The BenQ monitor is plugged in via HDMI.
I might return the current adapter (linked above) and get this adapter instead. I will then also try to use my DVI-A adapter with it if VGA doesn't work.

Below are some screenshot of the options windows 10 does display, I can't for whatever reason change the primary display or extend/mirror the display.

ONLY LL 3190T in Display Port with adapter.


If even the new adapter won't work I might buy a new monitor. The problem is that I wanted to buy a monitor that is using DisplayPort, so I am not sure if I will have the same problems that I have right now, because I don't know if it is windows 10, NVIDIA or the connection to the graphics card that isn't working.

Fixed my problem by plugging in the DisplayPort monitor first and then the HDMI now the NVIDIA control panel does recognize them correctly... I feel dumb for not trying this sooner.
