K900 | Probably | 20:42:24 |
Luke | Will it matter if I run X11 on another TTY at the same time? | 20:43:12 |
K900 | Shouldn't | 20:44:01 |
K900 | Oh yeah also just to confirm | 20:44:07 |
Luke | I can also rebuild with like kde or something if we are concerned | 20:44:17 |
K900 | You're not running this through any docks or extenders or whatever, correct? | 20:44:18 |
K900 | Just DisplayPort cable from the GPU directly to the display? | 20:44:28 |
Luke | Nah, right from the GPU to the monitor | 20:44:29 |
Luke | In reply to @k900:0upti.me
nix-shell -p sway and then sway from a TTY This seems not to have installed any graphical terminal, but just launching sway resulted in 60Hz - need to restart my machine and see if I can automatically launch konsole or something | 20:51:09 |
Luke | Is there a wayland equivalent for xrandr? I really need to update my rice lmao | 20:54:37 |
K900 | swaymsg if you're using Sway | 20:56:18 |
Luke | I used to have a windows 7 dual boot but accidentally nuked my boot partition once when I was drunk and didn't recover the windows section lmao - too bad I can't test it there | 20:56:39 |
Luke | Yeah I need to figure out the simplest way to so this - I think a config swap and rebuild is best? %mod + enter did nothing when I used the nix-shell approach | 20:57:33 |
Luke | K900:

K900 | OK so it's not advertising the >95 Hz modes at all | 21:10:33 |
Luke | Nope, seemingly not | 21:10:43 |
Luke | Perhaps this is somehow a monitor settings issue? | 21:11:25 |
K900 | Possibly | 21:11:28 |
K900 | Is there a link speed setting or something? | 21:11:34 |
Luke | I have not seen one that would obviously contribute to this, but let me search around in the settings a bit | 21:12:06 |
Luke | Turning on "Dual-Mode" does this lmao:

K900 | Yeah I'm guessing "dual mode" switches it to 1080p with a higher refresh rate | 21:14:04 |
K900 | Except it's still not running at the right link rate | 21:14:19 |
Luke | Ah getting a little closer:

Luke | This was an input compatibility setting | 21:17:08 |
Luke | I changed it from 1.4(DSC) to 1.4 - think this is the DisplayPort version? | 21:17:55 |
K900 | Yes | 21:19:04 |
K900 | Though it's strange that turning DSC off seemingly makes it work better | 21:19:14 |
Luke | Yeah I am a bit baffled | 21:19:24 |
K900 | DSC is Display Stream Compression | 21:19:25 |
