I have HDMI connected to a TCL TV and DVI connected to an Acer monitor. On startup both are working but just before login screen shows the DVI stops working and the HDMI is still working.
On the DVI I can go into PC bios and everything works up until where login screen is supposed to show but it never shows and the monitor light turns amber.
The DVI-D cable is new.
