I have a Gateway DX4870 (Intel Core i5) using an Intel HD Graphics Adapter.
The machine has a VGA port and an HDMI port.
I have tried using USB->VGA and successfully got a second monitor to work, but was unhappy with the resolution, so I decided to try an HDMI cable, since my monitor (ACER S2320) supports that and works great on my HP machine.
As I boot up, the HDMI works fine and the second monitor is a clone of the primary throughout the BIOS boot and the Windows starting screen. But as soon as Windows (Windows 7 Professional x64 SP1) comes up, the second monitor goes black. I cannot add the device, nothing. I have tried Windows-key P, I have tried control panel. The driver says it's up to date (8.15.10.2598)
It doesn't seem to be hardware or BIOS. It's not the monitor, that's working fine when I put it on my HP. I can't seem to find my HDMI port in Windows, any ideas on how to turn it on?
Thanks,
MikeT
