Topic: Does the PS5 intro video stutter for you?

I was able to buy a PS5 within a year from launch and this peculiar — on its own trivial — issue has persisted since. I'm referring to the short console boot animation (which you may rarely see if your TV is set to turn on with the console), the one with sparks flying. Audio playback is equally affected, unclear (but most of the times my speakers are still powering on).

The PS5 is connected to an LG C1 (with the included HDMI cable). I have no experience with the PS5 Pro. I've of course rebooted the console.

NOTE: The PS5's "start-up bleep" (emitted by the console) can be disabled in the settings, but not this boot video to my knowledge.

I'll factory reset the console if I can confirm that the problem isn't universal — it's unthinkable that Sony would allow the interface to drop tons of frames at trade shows and their live events. I assume there's some conflict with my hardware configuration.

I have a C1 OLED and a PS5 (Pro) I'll go check right now..

edit: Did both a reboot and a cold start, both completely smooth. Again, it is the Pro and I did get an after market 48GB/s cable, specifically this one:

Oh and while technically it shouldn't make a difference, I'm connected to HDMI port 3 on the C1.

There's brief slowdown as my Pro transitions from the intro to the dash - I assume due to the loading in of my relevant on and offline data.
