Workarea information (with the taskbar shown at the bottom of the screen):
- Dell P2815Q at 3840x2160:
| Text Size | Total Workarea |
|---|---|
| Smallest | 0, 0, 3840, 2120 |
| Second mallest | 0, 0, 3840, 2112 |
| Third Smallest | 0, 0, 3840, 2104 |
| Fourth Smallest | 0, 0, 3840, 2088 |
| Fifth Smallest | 0, 0, 3840, 2072 |
- HP ZR2740w IPS at 2560x1440:
| Text Size | Text Size | Total Workarea |
|---|---|---|
| Smallest | 0, 0, 2560, 1400 | |
| Second mallest | 0, 0, 2560, 1392 | |
| Third Smallest | 0, 0, 2560, 1384 | |
| Fourth Smallest | 0, 0, 2560, 1368 | |
| Fifth Smallest | n/a |
- Dell P2815Q at 3820x2160 & HP ZR2740x IPS at 1280x720:
| Text Size | Text Size | Total Workarea | Workareas |
|---|---|---|---|
| Smallest | 0, 0, 5120, 2120 | (0, 0, 3840, 2120), (0, 0, 1280, 680) | |
| Second mallest | 0, 0, 5440, 2112 | (0, 0, 3840, 2112), (0, 0, 1600, 840) | |
| Third Smallest | 0, 0, 5760, 2104 | (0, 0, 3840, 2104), (0, 0, 1920, 996) | |
| Fourth Smallest | 0, 0, 6400, 2088 | (0, 0, 3840, 2088), (0, 0, 2560, 1440) | |
| Fifth Smallest | 0, 0, 7040, 2072 | (0, 0, 3840, 2072), (0, 0, 3200, 1800) |
From this we can infer that the size of the taskbar (which reduces the available workarea) does not change with the monitor resolution, only the text size:
| Text Size | Taskbar Size |
|---|---|
| Smallest | 40 |
| Second Smallest | 48 |
| Third Smallest | 56 |
| Fourth Smallest | 72 |
| Fifth Smallest | 88 |
