Question Image will only appear on screen, if HMDI is plugged in AFTER boot up (Geforce RTX 3060 TI)

Hello!

I've come across a quite peculiar problem with my brand new PC.
As the title suggests, if I boot up the computer with the HDMI plugged in, the image will never appear on screen. I don't have the same problem with my two old PCs with the same monitor and cable.

If however, I boot up the computer without the HDMI plugged in, and then plug it in about 30 seconds after start-up, everything will be normal, in regards to the image. Besides being quite bothersome, I want to avoid hot plugging, since I've heard it can cause wear and tear.

Does anyone know what might cause this, and how to fix it?

A user on Reddit told me that I might need to get a new monitor, since he had the same problem a number of years ago, and getting a new monitor solved it for the user (thread).

Do you think that is the problem? Or is the problem something else?
If ture, then what monitor would be suited?

Help would be much appreciated.
Thanks!

Do you have ANY OTHER HDMI display to try?
Even a TV will work.
This may be the easiest way to figure this out.
I think it's possible it may be something funny with the display.
Only my TV and my laptop have HDMI ports. And the laptop would only have HDMI-output, I think.
But I could access another monitor by tomorrow.
I will try this, and update the threat.

I am still open to other suggestions.

Have you tried a new HDMI cable 2.0 or higher cable? 1.4 HDMI only supports 30 FPS at 4K. You need a 2.0 or higher cable to support the full function of your TV.
I haven't tried that.

I apologize if I'm misunderstanding, but I'm not worried about my framerate at the moment.

But do you think using a HDMI 2.0/2.1 would help my problem of the image not appearing, if the hdmi-cable is plugged in before booting up the PC?

I do think it will help, as your PC probably has defaulted to 60 FPS and your cable can't support it on boot up. I have ran into that before when my resolutions didn't match my monitor capabilities when switching them out. Another option is once you get into the computer, change your refresh rate to say 24 to see if that makes a difference, as that is the native support of 4K for HDMI 1.4 cable.
 
TV's only have hdmi as inputs. Displayport is a much better monitor connection, but a moot point.
It is a good thing that the tv has hdmi .1
And, that the 3000 series gpu's output 2.1
You should be good there.
HDMI cables have differing speed capabilities, I would buy one of the ultra speed hdmI 2.1 cables capable of 120hz.
It can't hurt.
Lesser cables are high speed at 60hz, and old cables at even less.

Some thoughts:
Is there a firmware update for your tv?
Possibly this could resolve the issue.

Are there any settings in the tv that might be applicable?

Have you tried sleep instead of powering off the pc?
The power usage during sleep is minimal, and the sleep/wake is much faster.
I currently have the opposite issue with my newly acquired LG oled 48" unit.
After a while i sleep, the unit powers off instead of remaining in sleep mode.
When I wake, it is not recognized.
But, if I power on first(easy to do with the remote) all works well.

Instead of activating by plugging/unplugging the HDMI cable, try using the remote to power on/off the unit.

Is there possibly a firmware update for your 3060?

Is your motherboard bios current?

Is your nvidia driver current?

Are there any motherboard chipset updates available?

Are you using a second side monitor?
A useful thing if you can.

That would allow you to access display settings and ask to detect the unit.

Interesting. Thanks for replying again.

I tried to set the refresh rate to 24. Didn't work, unfortunately.

I then tried to downscale the resolution to 1080p 60 hz. Also didn't work.

Could the problem still be with the monitor/cable?

I'm thinking of bringing the PC to my hardware provider tomorrow, so I can test it on another monitor with another HDMI. I'm hoping that will work.

Man. That took me a while, but I finally checked everything you mentioned.
There were a few things I hadn't updated. There was a firmware update for my TV that I did install, and a windows update. Good to get them updated either way. However, neither helped, unfortunately.

For now, I'll put it on sleep mode when not used. But I would still need to restart the computer for updates, so I think I'll look for a more complete solution.

I think I'll take the PC to my hardware provider and get it checked on one of their monitors.
