Hi ,

maybe I ask something stupid now , but no offense , I did it my self in the past :P

You said that HDMI is integrated to motherboard. Do you have a PCI graphics card also ? If yes then you must Unplug PCI for integrated to work .
Or look if integrated card is Enabled in Bios.

Thanks

@ NikTh

No i dont have a PCI graphics card connected, but I do have a PCI-E usb 3.0 card connected, could this affect it as well?

Regards

Hi ,
No, I think its Ok with Usb3.0 . I spoke about PCI(or PCI-E) graphics card , cause if you plug in then integrated will disabled.

Now , open a terminal and give the output of

====================
lspci -nnk | grep -iA2 vga
====================

and also check your TV , maybe wants something from the menu ,to change. At my tv , it wants to select the input device first (HDMI) .

Also try something else, first open your Computer and After plug in the HDMI cable to TV.

Thanks

Hi ,
can you please post the output of

==================================
cat /var/log/Xorg.0.log | grep -e WW -e EE
==================================

Did you try the suggestions above ?

1)About TV menu and input device (Is your TV has such menu?)

and try also below :

2)First open monitor and then open computer.

Thanks

Hi NikTh

I have tried the various combinations of connecting the computer to the TV (including the suggestions above and then some)

Hi ,

I cannot see anything notable in log.

If hardware is not the problem , I think you can convert the question in to bug.

Although It will be wise to wait few days for someone else (more experienced) to answer.

Thanks

Thank you NikTH

I went and purchase a NVIDIA graphics card today, which pick up first time, I have updated the NVIDIA drivers and rebooted. There is a slight problem as Ubuntu is currently identifying the my samsung 32 inch as a 46 inch tv and resizing it. i.e. the display layout is bigger than the actual screen

But I am sure it is easily fixed
