Hello @Sam1540 

We need you to always post what your Product number is when asking for assistance, so we know exactly what you have.

Open the HP Support Assistant and tell me the Product number. Thanks.

I can offer a couple of suggestions, it may or may not help.

Are you using an adapter with the HDMI cable for DP to HDMI or a single cable?

Do you have access to another one that you could test with?

Not knowing what model Obelisk and graphics card you have, did you try the other DP ports also?

Does your TV have more that one HDMI port? Did you go into the TV settings and make sure the correct port is selected for input?

Also, try a hard reset on the TV. Unplug the TV and all cables connected to it. Press and hold the power button down for 30 seconds. Plug the power cord and HDMI cable back in and try it.

You might try updating your graphics driver also. Again, don't know which one you have.
