• Hacking the LG Monitor's EDID

  OP's approach looks cool but a bit baroque. I'm also hacking around EDID issues and it turns out there's a nice GUI program to decode and (lightly) patch it: https://packages.debian.org/unstable/utils/wxedid

  I have to do more involved full EDID reconstruction surgery tho since I need to add DTD entries rather than just change existing ones. So I'm looking at [edid-generator] together with [cvt12]. The latter can calculate xrandr modelines for VESA standard timings that all seem to work with my TV. It adds an option for NTSC timing over regular cvt which is already in Debian.

• Arch Linux odd question

  4) On Xorg, a custom resolution is represented using a "Modeline", which can be manually calculated, or generated using a utility like cvt. There's also a modified version with more advanced options. Then the modeline can be temporarily added using xrandr, or permanently added using /etc/X11/xorg.conf. Though in my experience, the Nvidia driver is a bit picky about adding modelines sometimes, it seems to be more accepting if you add them in xorg.conf instead of xrandr, and also if you add settings documented here to xorg.conf to disable some forms of mode validation.

• Can set refresh rate with xrandr, but not xorg

  Instead of using cvt or gtf, I used cvt12 to get get my Modeline. With cvt12, I was able to get a refresh rate of 160. It is 10 frames lower than my monitor's max, but I'm still happy with this solution.

  If you haven't jumped ship to Wayland yet, maybe try using the same custom modeline for both screens? IIRC, you generate the modeline with a cvt calculator that supports reduced blanking v2, and then use it with xrandr --newmode , xrandr --addmode , xrandr --output --mode . Those 3 commands will need to be autorun on login, or possibly you could put the modeline in an xorg.conf.d snippet.

  As to how I got the "magic" numbers in the first command? It was done via this program: https://github.com/kevinlekiller/cvt_modeline_calculator_12. I ran it like this:

• How can I create a custom refresh rate?

  Then you use the cvt tool (https://github.com/kevinlekiller/cvt_modeline_calculator_12) to calculate a new modeline for your monitor (I'm assuming by "custom" refresh rate, you want to overclock your monitor)
