Today I stopped using a very old 1080p tv and began using a 4k Vizio smart tv. I don't have a monitor for my pc, and had been using my HDMI cord to connect to my tv. This worked fine on my old TV, but not my new Vizio. A few months ago, I tried connecting my pc to a newer LG smart tv, but I had the same issue with no display showing. I know the HDMI cable is fine because it'd been working for this purpose hours ago before swapping out tvs.

May be you need a newer spec cable for the modern tv, did you try the one supplied with it?

Is TV set to PC mode?

[jdoug312]

Yes the tv is set to PC mode. I'm using an HDMI 2.1 cable. Going to take it to best buy in a few hours to see if Geek Squad can figure it out. Based on reddit threads, it seems that No Display issues are common with Radeon, at least for models from 6400-7900xt.

hey its not your tv or cable its something with you display drivers

I have the latest drivers from amd, but yeah I'd read on reddit that Windows Update auto installs a bad driver or something to that effect. Because I don't have a monitor for my PC (never did, I always used my old TV), I can't change anything in that regard or tweak the Bios (which I'd read could also be the issue). I have a monitor coming today so hopefully I can tweak things, get it working on my TV, and return the monitor.

Definitely sorry to hear that man. I'm actually just about to accept your answer as the solution because permanently disabling Windows Update and then doing a full reset of my AMD drivers fixed the issue for me. I was going to try this (https://youtu.be/lT66m7GBTls?si=6ADS4Ei7iNCmi-D5) solution next, but I didn't end up having to. I'd updated my drivers on the AMD site several times before, but Windows Update definitely fudged something up. Going into registry edit and turning Windows Update off permanently *should* prevent this issue from popping back up. Currently using my new 50" as my monitor, and I've already packed up the monitor that came today so I can send it back tomorrow.
