DisplayFreeSyncColorAccuracy
Demonstrates how to obtain the Display FreeSync color accuracy when programming with ADLX and perform related operations.
Command Prompts
| Command Prompt | Description |
|---|---|
| 1 | Display FreeSync color accuracy support. |
| 2 | Get FreeSync color accuracy state. |
| 3 | Set current FreeSync color accuracy to disabled. |
| 4 | Set current FreeSync color accuracy to enabled. |
| M/m | Display the command prompt menu. |
| Q/q | Terminate the application. |
