Flashing power button

[Harolddevries]

Hi,

After connecting a third monitor (in fact it is a Samsung tv screen) to my computer,  my computer will not boot up anymore,

The power button keeps flashing (at a different speed as it would do in sleep mode).

When I remove the cable on the monitor/tv site all works fine and i can reconnect after computer has finished booting.

Anything I can do to stop this annoying behavior?

Kind regards,

All updates including a firmware update have been run.

I guess too much power is drawn from the computer when the tv is on.

When I turn on the tv after booting there is no problem and the tv can be used as a third monitor.

Issue is not solved but this topic may be closed.
