MOBO: B85M-D3H, BIOS latest F7
CPU: i5 4570
MONITOR: Samsung 2343BW connected via single link DVI-D
There is no display until windows login screen when using Intel Graphics 4600 when using motherboard DVI or HDMI.
Windows comes on in the proper native display resolution with no problems.
But I am unable to see POST or get into BIOS screen when the display is connected to DVI or HDMI motherboard output.
This happens with and without discrete card installed, with igfx option as the 1st display device set or not, with the monitor hooked up to motherboad DVI or HDMI outputs.
Tried different cables, different monitors. Tried dual link DVI-D, same thing.
Everything works over motherboard VGA port. My last board was B75M-D3H, which didn't have this issue and worked like a charm with my monitor.
Is there a BIOS option I'm missing,a bug in BIOS/VGA drivers or a hardware malfunction?
