Hi Karunakar,

Please check my response below.

Hi Karunakar,

Did you say the PC is accessible from laptop? This is what worked for me
(laptop, but not using the hotkeys to switch/duplicate displays):

$ xrandr
Screen 0: minimum 320 x 200, current 3286 x 1080, maximum 8192 x 8192
eDP-1 connected primary 1366x768+0+0 (normal left inverted right x axis y
axis) 344mm x 194mm
   1366x768      60.01*+
   1360x768      59.80    59.96
:
HDMI-1 connected (normal left inverted right x axis y axis)
   1920x1080     50.00*+  60.00    50.00    59.94    30.00    25.00
24.00    29.97    23.98
   1920x1080i    60.00    50.00    50.00    59.94
:

$ xrandr --verbose --output HDMI-1 --auto --primary

Hope, this works on your setup.
Thanks,
shreekant

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.
