Also I've figured out that TV also doesn't work in BIOS when connected over HDMI. So I can't see BIOS screen, GRUB, etc. When using DVI -> HDMI cable, it works too. Probably this is some BIOS issue if it initializes only first output... Can you please retest with kernel 3.5? We've fixed an awful lot of bugs in this area since then ... Same thing with 3.5.1 (can test other 3.5.x kernels later). This TV only works with MB when connected to DVI port using HDMI->DVI cable/adapter. When using HDMI port, TV shows "no signal" message. I'm attaching dmesg and xorg.log from this case Created attachment 66231 [details]

(In reply to comment #12) > Created attachment 66233 [details] > intel_reg_dumper output when booted with 3.5.1 kernel and HDMI cable (doesn't > work) There is a new display_debug.sh script in igt/scripts. Can you please output that as well (before and after) Assuming the AVI frame fixes did their job. Please reopen if this is still not fixed, thanks. |

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: --- dvi/randr 2012-04-14 20:54:03.000000000 +0300 +++ hdmi/randr 2012-04-14 20:57:29.000000000 +0300 @@ -1,6 +1,8 @@ Screen 0: minimum 320 x 200, current 1360 x 768, maximum 8192 x 8192 VGA1 disconnected (normal left inverted right x axis y axis) -HDMI1 connected 1360x768+0+0 (normal left inverted right x axis y axis) 160mm x 90mm +HDMI1 disconnected (normal left inverted right x axis y axis) +DP1 disconnected (normal left inverted right x axis y axis) +HDMI2 connected 1360x768+0+0 (normal left inverted right x axis y axis) 160mm x 90mm 1360x768 60.0*+ 1920x1080 50.0 60.0 30.0 25.0 24.0 1280x720 50.0 60.0 @@ -11,8 +13,6 @@ 720x480 59.9 640x480 72.8 75.0 66.7 60.0 720x400 70.1 -DP1 disconnected (normal left inverted right x axis y axis) -HDMI2 disconnected (normal left inverted right x axis y axis) HDMI3 disconnected (normal left inverted right x axis y axis) DP2 disconnected (normal left inverted right x axis y axis) DP3 disconnected (normal left inverted right x axis y axis) (Looks like HDMI1 means DVI on my MB and HDMI2 means HDMI).

I'm pretty sure that TV is ok as well as HDMI cable.
