Second Monitor Is Detected But No Signal Pc To Tv Via Hdmi

Hello!

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

 

Are you mirroring or extending your desktop?

 

TVs wont necessarily display a device simply because you have connected with a cable. You have to tell the TV which signal input it is to display. Read the TV manual on how to select from the available inputs
.

 

Just to clarify, if the cable is inserted in HDMI2 for example, HDMI2 is the input you must select on the TV.

 

I tried both. Mirroring and extending my desktop.

Yep. The TV is set on HDMI1, tried on HDMI 2 and doesn´t work. I have an update though, would appreciate any advice...

UPDATE:


After trying almost everything, I left the PC connected via HDMI to the monitor & forgot about it. My Desktop doesn´t have speakers yet, haven´t bought them.... I mention it because I don´t know if it´s related or not.

Well i opened youtube to check some videos, tried watching a video and suddenly the TV signal went on! Sound and all. It´s working perfectly now...but only If I play a song from youtube :S how so? I don´t understand the connection.

In fact, if the video ends, the monitor signal gest lost....until a new video starts playing. That just doesn´t make sense for me, what´s happening in here? And the max I can play the video is 720 P, i tried 1080 and the signal got lost.

And btw, don´t know if it´s important, but somehow I can´t find a resolution for my tv monitor to fit well :s Max is 1360x768 & it´s not showing perfectly on my tv....
