Did you tell Windows to use a "projector"? That's in the menu appears if you press Winkey+P.
I recently bought a Slimline HP Desktop 270-P024, yesterday I tried to watch a movie and decided to connect my desktop to my tv monitor through an HDMI cable. When I booted the PC, the HP Logo showed up on the TV Monitor, but then the signal went off.
I checked device manager and my tv is being detected, but yet the signal isn´t showing. I ramdonly tried changing the resolution through the Display Settings & suddenly the TV would display my PC but only for a few seconds... After a while no signal at all was found. The TV says something such as wait please.... But doesn´t display anything.
My specs are:
- Windows 10 operating system
- 12GB system memory
- 7th Gen Intel® Core™ i7-7700T processor
- INTEL HD Graphics 630
What can I do to fix this? Thanks in advance.
