Xorg has been smart enough to generate modelines on its own (and read them from EDID) for well over a decade. Last time I needed one manually configured was with XFree86 much too long ago to remember.
And you have a choice presented by lxrandr?
I can't answer. I don't have lx anything installed anywhere. I do have xrandr....
IIR many LG models have problems with EDID being incompatible and not supply the information in a way the Xorg works with. I ran into this when I first got the old 1953 and I've seen it discussed many time more in my googling for a solution for the 1942.
So CVT did a good job then and I'm hoping it can again now.
https://www.cnet.com/products/lg-l1953s-lcd-monitor-19/ If your Optiplex 755 is using its onboard Intel GPU and, that's what you connected the 1492 to, it should automatically use 1440x900,
OK, got the cvt:
# cvt 1440 900 # 1440x900 59.89 Hz (CVT 1.30MA) hsync: 55.93 kHz; pclk: 106.50 MHz Modeline "1440x900_60.00" 106.50 1440 1528 1672 1904 900 903 909 934 -hsync +vsync
Almost identical to the 60Hz 1440x900 on my ancient 19" Polaroid widescreen NTSC TV....
if the 1492's EDID reports it,
Ha ha ha. "is there a tool to determine that?" No the Xorg.0.log doens't tell me what EDID reports, only what 50-monitor.conf has.

Obviously this is due to broken EDID. 1280x1024 is really stupid looking at this physical ratio. xrandr in startup script as you can see above corrects that here. Any of the GUI screen configuration tools should be able to do the same.
and if you don't have some manual config somewhere to override it. If your kernel cmdline has a video= option and your Xorg is using the Intel DDX driver rather than the default Xorg DDX driver (modesetting), then Xorg will use that cmdline video= mode, assuming the display actually supports it. If the modesetting DDX is in use, this won't happen, same as with AMD and NVidia GPUs.
Just to.
???
But what else can I set the 1942 to?
I don't know if I understand what this asks. xrandr will report available modes. Are you finding none in your Xorg.0.log, or from xrandr, or krandr/kscreen, or arandr? -- Evolution as taught in public schools is religion, not science. Team OS/2 ** Reg.
