The "failure" occurred when using the dell docking station and display |
| 32 |
port from the dock to the monitor. I booted into windows (first time in |
| 33 |
over a year) and the same cabling worked perfectly for 3440x2500. |
| 34 |
|
| 35 |
I have now ditched the dock and am running hdmi directly from the laptop |
| 36 |
to the monitor and again success at 3440x2500. |

I will soon try Canek's suggestion of setting VIDEO_CARDS and using the |
| 39 |
built-in drivers. |
