TV/CCTV/NVR No signal

Hi
I am setting up CCTV, using my TV as Monitor via HDMI.

TV is fine.

When I switch the TV's remote to Monitor Mode, I get 'No Signal' on the screen.

The TV operates on an Indoor aerial. Is it because the aerial signal is too weak for the NVR ?. I just have no idea.

Any advise, please?.

Thank you.

 

NVR output mode may need adjusting , can you test it on VGA output?

 

Have you tried switching the tv to HDMI?

 

Thank you.

The TV is A Medion Smart 48 inch, 4K Ultra HD, with HDR X14357.

NVR is : XN4P-1T. 8MP 4 Channel HD-IP NVR 1TB.

I have a VGA cable to connect, but I would not know how to actually do a test.

I, at first, connected TV/NVR with HDMI cable, but I would not know how to 'switch' TV to HDMI.

 

If you dont know how to switch the input on your tv then its not going to make a difference what kind of cable you use. Its as simple as pressing the right button on the remote control.

 

Thanks.

On my Remote Control that button is marked 'Source'.

That is the one I pressed, when I got the 'No Signal'.

So, is the problem due to the Indoor Aerial?.

 

You would be better getting a five year old to show you how it works ….
Step 1 is the cctv dvr/nvr connected to the tv via a hdmi lead and is it switched on ?
Step press source on your tv remote ….does it give you a menu ? Or an onscreen label saying HDMI 1 if not press source again and again does the input onscreen change ? If it gives you a menu press up or down to select the input

note your cctv does not connect via the tv aerial but by an external source

 

This one is painful

 

Thank you, sparkymarka.

Prior to my FIRST post, I had the TV and NVR linked by the HDMI cable.
When I pressed the 'Source' button, 'No Signal' appeared. EXACTLY as I said in my FIRST post.

It DID NOT give a Menu.
It DID NOT show an onscreen label showing HDMI 1, or any HDMI.

The only thing I did not do is to press Source, again, and again, as you advise; I will do that.

Thank you for letting me know the aerial does not play a part.
Thank you.
