Hi,

I've got some really strange issue. I've followed GPU within ASUS MB:

00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 12)

I'm trying to attach HDMI TV to it. My motherboard has both HDMI and DVI
outputs. So when I'm using DVI output together with cheap DVI->HDMI cable,
everything works. But once I switch to HDMI->HDMI, display is detected,
but display nothing. TV shows "No signal" message.

I've tried to compare xrandr output for both cases and it looks same:

(Looks like HDMI1 means DVI on my MB and HDMI2 means HDMI).

Here is link to Xorg.log for both cases:

Any ideas why I can't connect TV using HDMI? I'm pretty sure that TV is
ok as well as HDMI cable. Also same TV works when connecting to laptop
with GMA4500 over HDMI.
