I have Samsung G9 Neo DQHD (Dual Quad HD) monitor, it has a native resolution: 5120x1440. The problem with this monitor in that I cant set text console resolution corresponding to its native resolution. KMS sets resolution as 3840x1080 so right-bottom part of screen is not used in full-screen TUI apps like: htop, mc, iptraf-ng. Also very annoying that man-pages also displayed only on upper-left part of screen. Using tools like Plymouth during boot sequence also looking very bad because of same issue. Has anyone this problem or any solution to solve it?
PS: Xorg works great with native resolution with 240Hz refresh rate (5120x1440@240Hz)

Does `hwinfo --framebuffer` list resolution options better than 3840x1080? If so, you can set these with the vga=... kernel parameter. If not, you may be out of luck for a native linux console, but you could use fbterm, yaft, or another framebuffer terminal instead.

hwinfo --framebuffer shows nothing. I think this is because terminal is configured with KMS

hwinfo --framebuffer shows nothing.
Nothing nothing? Or just no resolution listing? If nothing at all, did you run it as root or w/ sudo (you'd need to)?

Absolutely nothing. Yes I'm running it with sudo

xrandr -q
If you xrandr the mode to 3840x1080 (assuming that's an available mode), does it stretch across the entire screen?
If so, you could try to set the console video mode to 3840x1080, https://raw.githubusercontent.com/torva … modedb.rst
(I'm currently not buying that the mode is actually 3840x1080 - smaller-than-phys gets usually stretched or centered by the panel)
