Eyefinity
Demonstrates how to create an AMD Eyefinity desktop when programming with ADLX.
Command Prompts
| Command Prompt | Description |
|---|---|
| 1 | Display AMD Eyefinity support. |
| 2 | Create an AMD Eyefinity desktop with all the enabled displays. |
| 3 | Destroy all the AMD Eyefinity desktops. |
| 4 | Destroy the specified AMD Eyefinity desktop. |
| M/m | Display the command prompt menu. |
| Q/q | Terminate the application. |
