[PLUG] Using TV as primary display via HDMI from desktop PC.

[G Karunakar]

Hi,

  I have a desktop PC. Monitor went dead (after 10yrs usage). So I
have no display for PC now. If it was not for the lockdown, would not
be writing abt this as would have had a new monitor anyways!.

 Now PC boots fine, and can access it from laptop.
  I thought I could hook the Sony TV to PC using HDMI cable.
  I do it .
    Connect hdmi cable at pc & tv.
    switch on TV, switch to HDMI mode.
    switch on PC.
   But no display on TV.

  Motherboard has onboard graphics ( I had a nVidia card too but
removed it), There is VGA, Displayport, HDMI . 
  I would assume BIOS has some way to direct display output, but BIOS
cannot be reached. 
  TV is Sony Bravia 40", R Pi works fine with the TV.

I have a HDMI->VGA adaptor - which I assume is
no use in current situation .
 I also had bought a VGA-HDMI adaptor but cant find it (when its
needed the most! When I bought it I wondered if would every use it!!)

  So I assume now option is to get HDMI output, once kernel has
booted or X has started. Still searching how to do that.

 But if anyone has any solution/tips please do point out.
