Unable to set 1920x1080 resolution on Ubuntu 22.10 with Intel HD Graphics 4400 and VGA display

I have a PC with dual boot of Windows 10 and Ubuntu 22.10. I have an external TV as a monitor that is connected via VGA cable, and I know both the TV and VGA are perfectly capable of 1920x1080 because it works on Windows 10. However, when I try to set the display to 1920x1080 on Ubuntu's Settings -> Displays, the screen just blinks and reverts back to the old resolution.

I have the following system information from hardinfo:

    Operating System: Ubuntu 22.10
    CPU: Intel(R) Care(TM) i3-4130t CPU @ 2.90Ghz 1 physical process, 2 cores; 4 threads
    RAM: 3920360 KiB
    Motherboard: Hewlett-Packard 21D0
    Graphics: 1680x1050 Mesa intel(R) HD Graphics 4400 (HSW GT2) The X.Org Foundation
    Storage: ATASTS001_7012-PWS14
    Audio: HISA-Intel-FICA Intel PCH

The contents of my xorg.conf file are:

Section "Monitor"
    Identifier "Monitor0"
    Modeline "1680x1050_60.00"  146.25  1680 1784 1960 2240  1050 1053 1059 1089 -hsync +vsync
    Modeline "1920x1080_60.00"  173.00  1920 2048 2248 2576  1080 1083 1088 1120 -hsync +vsync
    Option "PreferredMode" "1680x1050_60.00"
EndSection

Section "Screen"
    Identifier "Screen0"
    Device "Device0"
    Monitor "Monitor0"
    DefaultDepth 24
    SubSection "Display"
        Modes "1680x1050_60.00"
    EndSubSection
EndSection

And when I run $ xrandr, I get the following output:

Screen 0: minimum 320 x 200, current 1680 x 1050, maximum 16384 x 16384
VGA-1 connected primary 1680x1050+0+0 (normal left inverted right x axis y axis) 0mm x 0mm

DP-1 disconnected (normal left inverted right x axis y axis)
HDMI-1 disconnected (normal left inverted right x axis y axis)
DP-2 disconnected (normal left inverted right x axis y axis)

How can I get 1920x1080 on Ubuntu 22.10?"

See my previous post here about `cvt/Modelines` with reduced blanking. I would try that and/or try a normal `Modeline` but reduce the refresh rate down from 60: https://askubuntu.com/questions/1337869/certain-programs-disable-second-monitor/1338095#1338095

Try this. Get a Modeline using Reduced blanking:

cvt -r 1920 1080 60

Which will result in something like:

# 1920x1080 59.93 Hz (CVT 2.07M9-R) hsync: 66.59 kHz; pclk: 138.50 MHz 
Modeline "1920x1080R"  138.50  1920 1968 2000 2080  1080 1083 1088 1111 +hsync -vsync

Then take the second line from that, remove the word Modeline and issue a xrandr --newmode command like:

xrandr --newmode "1920x1080R"  138.50  1920 1968 2000 2080  1080 1083 1088 1111 +hsync -vsync

Finally change to that mode:

xrandr --output VGA1 --mode 1920x1080R

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
