Thanks. Looks like this is also a kernel bug...

Title:
[modeset][i915] Native resolution (EDID detailed mode) of 2560x1440
not listed, defaults to 1920x1080 instead
Status in linux package in Ubuntu:
New
Status in xorg-server package in Ubuntu:

Bug description:
The PG278QR monitor supports 2560x1440. After installing Ubuntu 20.4,
the max resolution presented in the Settings app is 1920x1080, and
this resolution is the one that it uses. Switching between the Nvidia
driver or the Intel driver (laptop has low-power intel gpu too)
doesn't correct the problem.
Digging in deeper, based on
https://wiki.ubuntu.com/X/Troubleshooting/Resolution#Problem:__Wrong_resolutions.2C_refresh_rates.2C_or_monitor_specs
Under Wrong resolutions/refresh rates/or monitor specs, step 3 is to
use get-edid | parse-edid.
After applying the mode that I wanted manually via xrandr --newmode
and xrandr --addmode, I was able to select the max resolution of the
monitor and works correctly, until reboot. I will add it to my
xorg.conf next.
Here is information I collected:

Will scan through until the first EDID is found.
Pass a bus number as an option to this program to go only for that one.
Bus 0 doesn't really have an EDID...

Looks like i2c was successful. Have a good day.

"Mode 0" above is the mode that I want to use, which doesn't appear in
the Settings app list of available resolutions.
I used "Mode 0" to via xrandr --newmode:
~$ xrandr --newmode "Mode 0" 241.50 2560 2608 2640 2720 1440 1443 1448 1481
+hsync -vsync
Then, xrandr --addmode:
~$ xrandr --addmode HDMI-1-1 "Mode 0"
Then in Settings app, I can select the 2560x1440 resolution for the ASUS
PG278QR display.
