I hope you find your Support Forum experience a positive one! It is a great place to find the help you need, from other users, HP experts, and other support personnel. I understand that your screen remains lit, when the computer goes to sleep I am happy to give you a hand with this.
From the computer side, you would want to look at these documents to change the power settings for the graphics adapter, and output to the external display.
For the rest, you would need to look at the setting on the display itself. Most displays have adjustments for their own sleep mode, when there is no received signal. What is the model of the display? You can consult the manual for the display, or use its on screen menu to make any adjustments. The method will vary from one make, model or brand, to the next.
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.
