Hi,
I have recently been pushed the Windows 10 Fall Creator Edition (Build 1709) and after installation I cannot get any HDMI output (connected to an Acer S240HL screen) - I see an "input not suppoorted" message on the Acer monitor. If I roll back to a pre-1709 build the display works.
I have the Intel HD 620 Video driver 22.20.16.4799 installed, although I also rolled this back to the current version on the Dell site (Intel-HD-Graphics-Driver_1H6KX_WIN_21.20.16.4627_A04.exe) before a second attempt at a reinstallation of Fall Creator.
Has anyone seen anything similar, or a workaround?
