@elvishjerricco:matrix.org | In reply to @charles:computer.surgery does it work in windows? I know it at least hits 165Hz in windows. I dunno if it has this weird red pixelation problem | 04:11:34 |
@elvishjerricco:matrix.org | But i'd wager everything it's fine in windows | 04:11:49 |

Charles ⚡️ | Worth checking I think | 04:29:33 |
@elvishjerricco:matrix.org | Yea, no hdmi 2.1 on linux right now unless you use a DP -> hdmi adapter like the one baked into intel graphics: https://gitlab.freedesktop.org/drm/amd/-/issues/1417#note_1795980 | 05:08:53 |
@elvishjerricco:matrix.org | In reply to @charles:computer.surgery Worth checking I think and yea, 1px vertical red line in MS paint on windows looks perfectly fine | 05:14:06 |
@elvishjerricco:matrix.org | I've ordered a DP 1.4 -> HDMI 2.1 adapter, if only to see if it combines the best of the two or the worst of the two :P | 05:14:32 |
Charles ⚡️ | good luck! | 05:35:44 |

@elvishjerricco:matrix.org | You've gotta be fucking kidding me lol | 05:37:10 |
@elvishjerricco:matrix.org | That's amazing | 05:37:12 |
@elvishjerricco:matrix.org | The problem was staring me in the face the whole time | 05:37:20 |
@elvishjerricco:matrix.org | Almost literally | 05:37:23 |
Charles ⚡️ | lmao | 05:37:25 |
Charles ⚡️ | in your defense i didn't connect the dots either | 05:37:42 |
@elvishjerricco:matrix.org | I wonder what it's doing to result in janky 4K@120 instead of just not offering 4K@120 | 05:40:12 |
@elvishjerricco:matrix.org | Some kind of lossy DSC or something? But I thought DSC was supposed to be lossless | 05:40:47 |

@atemu12:matrix.org | In reply to @elvishjerricco:matrix.org I wonder what it's doing to result in janky 4K@120 instead of just not offering 4K@120 Chroma subsampling perhaps? | 06:32:42 |
@atemu12:matrix.org | If you can to 1px greyscale lines but not coloured ones, that'd be a sign for that | 06:33:26 |
@elvishjerricco:matrix.org | ohh that would make sense | 06:33:26 |
@elvishjerricco:matrix.org | is there a way to check for that in linux? | 06:33:49 |
@elvishjerricco:matrix.org | like, now that you mention it, it seems pretty obvious that that's what's happening | 06:34:01 |
@elvishjerricco:matrix.org | so something in linux is making the decision to do that, right? | 06:34:12 |
@atemu12:matrix.org | Probably AMDGPU? | 06:34:26 |
@atemu12:matrix.org | No idea | 06:34:30 |
@atemu12:matrix.org | I haven't figured out how to query display link info either | 06:34:56 |

Charles ⚡️ | colors are red, yellow, blue, green, pink, white, cyan, grey, then blue on red, and red on blue | 06:37:17 |
