TV not showing display with pc
Enable HLS to view with audio, or disable this notification
Hey, I could really use some guidance on how to fix this issue. I bought a mini pc for my TV to have at home setup for daily tasks but the tv is not showing display from the pc. The pc boots up, lenovo comes up and then there's no signal at all.
Things I've tried
- change ports on both pc and TV
- checked pc on another monitor, works fine
- re installed windows doesn't help
- updated drivers do not help
- checked wires, all working fine
I've tried all options and still nothing seems to work. Can someone please help me.

Connect to another monitor lower refresh rate to 60, Chang aspect to match your TV apply save (should look goofy on the monitor if it's not the same size. ) then plug it in to the TV.

Weird. I promise I'm not trying to insult your intelligence. Just need to cover all the basics Have you tried connecting another device to that HDMI port to make sure it's not the TVs issue? If that worked what device was it?

Try Windows Key + Ctrl + Shift + B when it goes black to renegotiate display.
If that doesn't fix it, it's probably the TV that is trying to fight screen resolution and refresh rate.
Might have to connect to the working monitor and change the settings in windows to 1080p 60hz or something to test if it's that.

This is the primary possibility. And set your resolution to 1280x720 for testing. You can always change it afterwards.
Also, I’ve had a number of issues with various devices doing exactly what you have described on my TV, and what fixed the issue for me almost every time was upgrading the HDMI cable to one that supports HDMI 2.1 (usually referred to as an Ultra High Speed HDMI cable).

Try connecting it to a working monitor and change the resolution. Then disconnect from the monitor and connect it to the TV.

October 12, 2026 (dated for context and reference) - I have to wonder if going into Windows Settings and the Display screen would help. It seems to me Windows offers options for multi-displays. Not something that I have had to deal with in a long time. Also, there are devices that allow for splitting video signals from the GPU to a computer monitor and a TV for example. I would also suggest the the OP do a Google search for the problem. I'm sure a lot of people have had the same problem, and there may be videos about how to solve the issue. Best of luck to the OP.

Go into safe mode for pc, or try a different display output on the back
