I have been trying to connect my xps 13 9350 to a Hanns.G monitor with a resolution of 2560 x 1440 using a DA200 adapter without success. The display is detected, but the built in monitor just goes blank and the external monitor shows nothing.
Has anyone had any success connecting this laptop to an external monitor?
This issue can be resolved by updating the Thunderbolt controller driver to version 126.96.36.199 ,A01 and also updating Thunderbolt firmware to version 02.11.06 ,A02. Both of these drivers are available from the Dell support site. Besides this update your Graphics driver and the BIOS firmware to the latest version. That should ideally solve the problem.
