Ubuntu 18.04 cannot recognize monitor

The attached image shows that Ubuntu cannot recognize my display, and there is only one resolution to choose.

Screen capture of Settings-Displays

Monitor: LG 38CB99 3840*1600
Graphic card: RTX 2080ti

I tried to install the Nvidia-390 driver following the instructions and restarted, but this problem persists.

I am a beginner of Linux, and I need a more comfortable screen presentation to proceed learning. Could you help solve my problem?

xrandr result:

xrandr: Failed to get size of gamma for output default

Screen 0: minimum 1024 x 768, current 1024 x 768, maximum 1024 x 768

default connected primary 1024x768+0+0 0mm x 0mm

   1024x768      76.00*

When I run lspci:

lspci -k | grep -iEA5 'vga|display|3d'

Result:

Try another cable and see the result

post xrandr results

It may also be some problem with kernel or driver. Or maybe monitor's EDID is broken (so you need to use workaround)

Workaround:
xrandr should tell you there is a virtual display VIRTUAL1 disconnected or something.

xrandr --newmode NEWMODE_NAME $(cvt <WIDTH> <HEIGHT>|tail -n 1|awk '{$1="" ;$2="";print $0}')

xrandr --addmode VIRTUAL1 NEWMODE_NAME

xrandr --output VIRTUAL1 --mode NEWMODE_NAME

xrandr --addmode <YOUR OUTPUT JACK> NEWMODE_NAME

xrandr --output <YOUR OUTPUT JACK> --mode NEWMODE_NAME

Thank you for response. 1. I am using DP; however, HDMI does not give any signal. DP works very well in Win10. I installed dual OS. 2. xrandr: Failed to get size of gamma for output default Screen 0: minimum 1024 x 768, current 1024 x 768, maximum 1024 x 768 default connected primary 1024x768+0+0 0mm x 0mm 1024x768 76.00* The first line of your additional command gives: bash: command substitution: line 10: syntax error near unexpected token <' bash: command substitution: line 10: cvt <WIDTH> <HEIGHT>|tail -n 1|awk '{$1="" ;$2="";print $0}')' Any new suggestion, please?

Finally I found the solution. It is quite easy.

Just download the .run file from Nvidia website and install it:

sudo chmod +x /downloads/NVIDIA-Linux-x86_64-410.78.run

sudo /downloads/NVIDIA-Linux-x86_64-410.78.run

The interface is more friendly than Linux portal, and you do not have to type commands.

After finishing, restart. Everything will be all right!

Finally I found the solution. It is quite easy.

Just download the .run file from Nvidia website and install it:

sudo chmod +x /downloads/NVIDIA-Linux-x86_64-410.78.run

sudo /downloads/NVIDIA-Linux-x86_64-410.78.run

The interface is more friendly than Linux portal, and you do not have to type commands.

After finishing, restart. Everything will be all right!
