I have a smart TV and I have no issues with connecting to it wirelessly. I can mirror the screen without any issue. However I cannot get it to Extend the laptop screen. All other casting functions seem to work fine. If I select extend display the TV will show my desktop only, and the laptop will work as normal, pull up windows, apps, etc. But the TV display does not change.

@APATOR Welcome to HP Community!
I understand that you would like to extend the display.
Configure the display with Windows
Extend or duplicate the desktop with a second monitor.
-
Right-click anywhere on the desktop, and then click Display settings (Windows 10) or Screen Resolution (Windows 8).
-
Make sure the correct number of monitors displays.
Windows 10
Windows 8
-
If all of your monitors display, continue with these steps.
NOTE:
Two monitors might display as one, with 1|2 in the center, indicating the same screen duplicated on two monitors. To change to an extended desktop display, continue with these steps.
-
If not all of your monitors display, make sure the cables are securely inserted, and then click Detect.

Thank you for the response. However following the instructions changed nothing. I can wirelessly connect. Only the inactive desktop will display on the other monitor. And the laptop has an active display. It doesnt seem to make any difference as to how I arrange screen 1 or 2. I can project the laptop screen to the other monitor without issue, but I cannot extend the display. I welcome more suggestions.

Honestly, I dont know if it ever worked in the past. I tried your recommendations and I can get 2 separate desktops to show in the 'extend ' setting, but I cannot actually "extend" the view of the primary screen. I can't help but think I'm just not setting something correctly, but it is not obvious to me.

OK, I just figured it out,,,,why this is not shown in a instruction somewhere IDK. I must connect and select extend screen. No problem, but in order for the display to be extended to the next monitor, you must exit full screen "make a window" on the main screen you wish to extend. Then drag or "resize" the window to extend it to both screens. Probably something most users take for granted that everyone should know. I didn't.
