 K900 | Probably not at all tbh | 21:41:50 |
| K900 | But that is VERY STRANGE | 21:41:57 |
| K900 | The hardware should definitely be able to do it | 21:42:02 |
 Luke | I thought DSC was DisplayPort only tech? I could be very wrong | 21:42:13 |
| K900 | Also HDMI 2.1 | 21:42:30 |
| Luke | It was a weird GPU that they nearly immediately dropped support for | 21:42:41 |
| Luke | lmao | 21:42:47 |
| Luke | It very well might be able to do it, and just doesn't have firmware for it | 21:43:04 |
| K900 | Oh god wait | 21:44:32 |
| K900 | Desktop Vega doesn't have DCN | 21:44:36 |
| K900 | Yeah OK this is a mess | 21:44:40 |
| Luke | lmao | 21:44:43 |
| K900 | Mobile Vega has a significantly newer display controller IP | 21:44:50 |
| Luke | But still, why doesn't the monitor advertise these speeds with the compression disabled?! What a mess | 21:45:34 |
| K900 | Because it can't | 21:45:51 |
| Luke | No I mean the 120Hz speed | 21:46:03 |
| Luke | Clearly it can do that, it is right now | 21:46:12 |
| K900 | Probably because it doesn't really make sense for them to advertise non-DSC modes | 21:46:16 |
| K900 | Except for weird compatibility reasons | 21:46:22 |
| K900 | At which point you will probably opt into them anyway | 21:46:30 |
| Luke | Fair I guess | 21:46:44 |
| K900 | I am very confused by why AMD is advertising those as DP 1.4 though | 21:46:56 |
| K900 | Because DP 1.4 is supposed to include DSC | 21:47:01 |
| Luke | I gotta try HDMI now, see what it advertises | 21:47:16 |
| K900 | It is going to be very little | 21:47:27 |
| K900 | https://trychen.com/feature/video-bandwidth | 21:47:50 |
| Luke | Oh yeah, only advertises 60Hz | 21:52:09 |
| Luke | Well, this has been an interesting lesson in display tech | 21:52:25 |
 ElvishJerricco | interesting. If this is correct, it seems the most I can get out of this 4K display without DSC is 75Hz | 22:06:36 |
| ElvishJerricco | wonder why that is. DP 1.4 can do 4K@120Hz without DSC, can't it? | 22:07:58 |
