I have a problem about my monitor, I use two monitors together but always a black screen when I plug in the HDMI and DVI together, but when I plug them in separately they want to turn on normally. I use gtx 1650 super. I hope to find an answer to this problem
 
I can't confirm this without exact GPU model, but it may be that DVI and HDMI ports are interconnected and can't be used both - only whichever one you need. Some manufacturers do that to simplify their PCB and make their card cheaper. You will have to use other ports for your monitor. For example, DisplayPort, and just use a DVI to DisplayPort adapter if your monitor doesn't have a display port.

This shouldn't be an issue. Right-Click anywhere on your desktop and open the NVidia Control Panel.
Under the Display Tree there should be an option for Set Up Multiple Displays
Verify that both displays are shown there.
Make sure both are select under #1

Both displays are connected to the graphics card? This should work without issue as I've been running dual-displays since forever! Currently running on a GTX 1060.

both are connected to the graphics card because I use an Intel i3 9100f without any integrated graphics
