Hi there @benzxc,

May the Forums be with you!  I understand that your display is not coming on properly.  I am happy to give you a hand with this.

Please see the following:  HP Flat Panel LCD Monitors - Monitor is Blank, and let me know if there is any change or any messages that appear on the display at all.

Please let me know whether that works for you, and if it does resolve your issue, please mark this post as a solution. Kudos would also be appreciated.

Yet again, this didn't help. I can't even get a loading screen on. The blue light at the bottom right of my monitor (HP 2711x) keeps blinking rapidly. At first it was blue, five minutes later it is yellow. Changing it to an HDMI and VGA didn't help. The power supply is fine. I'm so lost.
