HDMI stopped working in Windows 8 (Still works in Bios)

[rusevas]

I recently built a new computer on the Shuttle Chassis (Model SH87R6) The HDMI is onboard, as is the video card, which is just an Intel HD Graphics card. My monitors are connected via HDMI and run through a powered splitter to 2x HDTVs. (The display is duplicated). I'm running Windows 8.1 and I've updated my display drivers.

Initially this setup worked perfectly.

But now, when I boot my computer, the display works through BIOS, flashes the windows logo, then goes black. But if I connect an HDMI cable directly from the TV to the PC, it starts working . Swap it back to the splitter, and it doesn't work (Unless I"m in BIOS).

I know it's not the splitter, because both displays work until windows boots. So for some reason, Windows stopped recognizing both displays. I suspect a Windows update was applied last time the PC shutdown, but there has got to be a fix.

check your BIOS setting under Video adapter settings.

Maybe I don't know what I'm looking for but the only display related option in my BIOS was for which to boot: Onboard, PCI or auto.

What am I missing?

Anybody able to help with this?

if you dont have a separate video card. Choose onboard.

I'd already done that and there was no change. Any other ideas?

Windows occasionally gets dumb and decides to make the primary monitor the one you don't have connected. I was dealing with a computer at work that only had a single monitor connected to it but kept insisting that the projector it was no longer attached to was the only screen it wanted to output to.

Connect it to the HDTV directly with an HDMI cable and check your display settings in Windows, windows may just be being windows.... The BIOS splash screens will generally get pushed to all monitors connected so that isn't super helpful, i see it on both of my monitors upon boot, so i suspect windows just went on the fritz.
