@k900:0upti.meK900Oh yeah also just to confirm20:44:07
@luke:vuksta.comLukeI can also rebuild with like kde or something if we are concerned20:44:17
@k900:0upti.meK900You're not running this through any docks or extenders or whatever, correct?20:44:18
@k900:0upti.meK900Just DisplayPort cable from the GPU directly to the display?20:44:28
@luke:vuksta.comLukeNah, right from the GPU to the monitor 20:44:29
@luke:vuksta.comLuke
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:vuksta.comLukeIs there a wayland equivalent for xrandr? I really need to update my rice lmao20:54:37
@k900:0upti.meK900 swaymsg if you're using Sway 20:56:18
@luke:vuksta.comLukeI 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 there20:56:39
@luke:vuksta.comLukeYeah 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

@k900:0upti.meK900OK so it's not advertising the >95 Hz modes at all21:10:33
@luke:vuksta.comLukeNope, seemingly not21:10:43
@luke:vuksta.comLukePerhaps this is somehow a monitor settings issue?21:11:25
@k900:0upti.meK900Possibly21:11:28
@k900:0upti.meK900Is there a link speed setting or something?21:11:34
@luke:vuksta.comLukeI have not seen one that would obviously contribute to this, but let me search around in the settings a bit21:12:06
@luke:vuksta.comLuke

Turning on "Dual-Mode" does this lmao:

21:13:23
@k900:0upti.meK900Yeah I'm guessing "dual mode" switches it to 1080p with a higher refresh rate21:14:04
@k900:0upti.meK900Except it's still not running at the right link rate21:14:19
@luke:vuksta.comLuke

21:16:48
@luke:vuksta.comLukeThis was an input compatibility setting21:17:08
@luke:vuksta.comLuke I changed it from 1.4(DSC) to 1.4 - think this is the DisplayPort version? 21:17:55
@k900:0upti.meK900Yes21:19:04
@k900:0upti.meK900 Though it's strange that turning DSC off seemingly makes it work better 21:19:14
@luke:vuksta.comLukeYeah I am a bit baffled21:19:24
@k900:0upti.meK900DSC is Display Stream Compression21:19:25
@luke:vuksta.comLukeUh, GPU may not support it? 21:19:36
@luke:vuksta.comLukeOld GPU21:19:40
@luke:vuksta.comLukeWell at least we have hit 120Hz - only halfway to go until it's running as specified 21:20:20
