Gigabyte H55N-USB3: No video on HDMI

Posted on

Problem :

I built a new PC with a Gigabyte H55N-USB3 / Intel Core i5 650.

With a monitor plugged in the DVI port, everything works fine. I installed Windows 7 32-bit and enabled remote desktop connection. After that, I unplugged the monitor, plugged it into network and installed everything else (drivers, programs, etc) via RDP.

However, when I try to use the HDMI port on my TV nothing appears. Neither during the boot, neither after Windows starts. The TV says there’s “no signal” (if I remove the cable the message changes to “check cable”). The cable is new, and it is working fine with my home theater on same TV (by the way, it is the cable which came bundled with the home theater).

Video driver is the latest from Intel site. Anyway, this shouldn’t be the problem since there is no image during the boot.

Any ideas or tips would be welcome. I’m googling around but found nothing useful, yet.

Update

I found someone with exactly same problem,

but in his case the problem “vanished” without explanation… 😛 (I love machines…)

And, yes, I turn the computer on with ONLY the HDMI cable connected on video outputs. No cables on DVI/VGA connectors.

Solution :

Solved. I bought a new HDMI cable (cat2) and everythings works fine now! The cable which came with my home theater must be an incomplete one (it is thinner than the new one)
