Why did ps4 / xbox input lag?

With a PC there's almost no input lag at all but with ps4 / PS5 / xbox it is. Did xbox and ps4 / PS5 automatically activate vsync?

That's because bluetooth isn't as fast as a cable

Even if you play with cables, input was there

Because it is not permanently integrated, but only USB 1.0 or sometimes 2.0 connections, plus the cable that is not optimized for the type, makes it slower

My TV has an input delay of 10ms in connection with the Series X in gaming mode.

There's no longer any noticeable delay!

On the Xbox there's also the possibility of activating Freesync (variable update rate), provided a suitable TV is available.

Then there's no more lag at all.

And no delay should be possible via cables either. The controller of the series consoles has a radio delay of 8ms, which is also not noticeable.

So…

Forgot to activate the gaming mode on the TV?

Maybe a bad TV with too high a latency?

I think it's a rumor that PCs have no input lag. Why do manufacturers like Corsair advertise with low latency for mouse, keyboard and headsets?

Did xbox and ps4 / PS5 automatically activate vsync?

No, it is not activated automatically, but it can be switched on in the game settings. With the Xbox consoles, AMD Freesync technology is even possible, which enables Xbox users to reduce input lag and eliminate screen tearing even at high frame rates.

The greatest input lag is with the Playstation, mainly due to the slow Bluetooth controller and the missing ALLM & Freesync function

ALLM is an Xbox exclusive feature in the console area, in which the input lag is drastically reduced by the monitor, console and controller communicate almost input-long-free, actually an unnecessary feature for the Xbox, as the Xbox has by far the lowest input lag due to the Xbox has wireless technology.

The Xbox does not use Bluetooth at all, but the in-house Xbox wireless network.

Due to a small error, the question was still being written and processed to the end.
