 K900 | The GPU is physical | 10:49:23 |
| K900 | So you can't connect virtualized things to it | 10:49:29 |
 crushing-smite | So, I really need a second monitor to use looking glass? | 10:49:31 |
| K900 | You can buy a dummy HDMI plug off Aliexpress or something | 10:49:38 |

So, I really need a second monitor to use looking glass? No, you can connect both GPUs to the same monitor | 10:49:46 |
| K900 | If it has multiple inputs | 10:49:50 |
| K900 | And then just use the input from the host GPU | 10:49:56 |
| crushing-smite | Then looking glass is not accessing the GPU memory, it is accessing the actual physical screen's buffer? | 10:49:58 |
| K900 | The actual physical screen's buffer is in the GPU memory | 10:50:09 |
| crushing-smite | but not exactly acccessible until there's a physical plug, right? | 10:50:27 |
 @atemu12:matrix.org | crushing-smite: It's recording the physical screen and passing that recording through shared memory AFAIUI | 10:50:43 |
| K900 | It doesn't exist until there's a physical plug because the GPU doesn't see any displays connected to it | 10:50:46 |
| K900 | So it's just not enabling graphical output at all | 10:50:55 |
| crushing-smite | :( | 10:51:05 |
| crushing-smite | what a waste of non-wasted electricity | 10:51:14 |
 philipp | It's not that bad if you just use on of these fake display plugs. | 10:51:37 |
| K900 | It's a negligible amount of electricity if you just use a dummy plug or your existing monitor | 10:52:02 |
| K900 | The GPU usually can't tell if it's the active input on your monitor | 10:52:10 |
| K900 | So it'll still render even if you have the monitor set to not display it | 10:52:20 |
| crushing-smite | yeah, but I mean, what a waste of electricity as in GPU cycles | 10:52:51 |
| K900 | GPU cycles aren't really wasted | 10:53:05 |
| crushing-smite | could have still rendered stuff even if it knows there's no output 🤔 | 10:53:09 |
| K900 | Well except the scanout hardware | 10:53:15 |
| K900 | Which is basically idle anyway | 10:53:20 |
| K900 | Because the display is what's driving the scanout | 10:53:24 |
| @atemu12:matrix.org | It could, theoretically. Windows drivers just simply don't do that. | 10:53:38 |
| K900 | As in, the display will ask the GPU to feed it frames | 10:53:40 |
| crushing-smite | aha, so the trigger for GPU's action is actually the display? | 10:53:43 |
| K900 | The GPU will still render frames | 10:53:52 |
| crushing-smite | interesting | 10:53:53 |
