issue with GTX 1650 Super when connecting displays

OS : Windows 10 Pro Build 1909 x64

CPU : i5 10400

RAM: 16GB x 2 3200Mhz Corsair Vengeance LPX @2666Mhz

Mobo: Asus Prime B460 Plus

I have a Gigabyte Windforce GTX 1650 Super OC Graphics card... it has 1xDP, 1xHDMI, 1xDVI-D Dual Link. i have one HP display connected via HDMI ( 1920x1200 ), the other monitor is connected via DP ( with a DP to VGA adapter ) and the resolution of the second monitor is 1024x1280 ( in portrait mode )

i need to connect the third monitor to the same computer ( which has a resolution of 1440x900 ), but when i fix the 3rd monitor, everything starts to mess up, sometimes only the monitor i plugged in ( the 3rd ) shows an output and others stop working, after a restart the same happens..

so i thought of removing the 2nd monitor ( 1024x1280 in portrait ) and tried fixing the 2nd monitor ( with the same DP to VGA adapter ) and the resolution wont change to 1440x900, it just stays at 1280x1024 ( landscape ).. after a restart, only the third monitor works ( there is no output in the other monitor )

does this have something to do with my graphics card? or displays? or the way i use to connect them ( because VGA is analog, for the factor, but what about the 2nd thing i tried???? )

Product i am going to buy ( this is mentioned as a active, so i think, it will work, but im not sure about it ) : https://www.daraz.lk/products/pm-dvi-d-241-pin-male-to-vga-15pin-female-active-cable-adapter-converter-1080p-i101880698-s1007842263.html?spm=a2a0e.searchlist.list.1.6bd7a660vUKI9x&search=1

sadly, i cant go to a shop and ask for a DVI-D Dual Link cable cuz ive done that many times, and nobody in the freaking shop knows what i mean! :-3
