Controller Input not working or very delayed

If the controller that came with the Xbox works perfectly fine and the controller from Amazon has had updates and still has the input delay I would highly recommend getting in contact with the manufacturer if it is still within warranty. There may likely
be a fault with the controller.

I appreciate you replying. I have tried the controller test before and it makes no difference. The input delay occurs on any and everything that I do on the xbox. When it is connected via USB-C it will randomly and frequently disconnect me but the light is still on the controller. Its very very strange. When I press the buttons during gameplay, they feel heavy and I have to hit them more than twice in order for them to register. I dont know if its an electrical input delay or what but its beyond upsetting.

Updated:

I found that my soundbar SONY HT Z9F soundbar use HDMI 2.0 of which bandwidth is 18gbs connect to my TV using eARC port, so I changes my HDMI to

8K HDMI of which soundbar is 48gbs, and the delay improve a lot that it is hard to notice now.

I have tested. My set is

TV has enable eARC and set sound passthrough, HDMI BITSTREAM. XBOX SERIES allows PASSTHROUGH.

XBOX SERIES X --> LG 65 QNED90 --> SONY HT Z9F (eARC)

there is very noticeable delay on Atmos but don't have delay on any uncompressed sound like 5.1 or 7.1

XBOX SERIES X --> SONY HT Z9F (eARC) --> LG 65 QNED90

the atoms sound is sync with image, but I got a ton of delay on controller input, so I set TV image mode to Game Optimize,

and set game mode to FPS, the controller input delay is gone, but now, i got atoms delay back...

By the way, because my TV doesn't support DTS - X PASSTHROUGH, so when I connect XBOX to my soundbar, I could enable DTS X, and DTS X is working perfectly and there is no any delay comparing to Dolby Atmos.

Razer Blade 15 with RTX 2070 MAX Q --> LG 65 QNED90 --> SONY HT Z9F (eARC)

I don't have any input or atmos sound delay in this set.

So here is conclusion:

xbox series x has issue to passthrough Atmos content, even thought it is directly connect to sound bar, the sound or TV try to delay image to sync with atmos sound which causes a ton of input delay. But once you set the TV into low legacy input mode to get rid of input delay, the Atmos sound delay will be back.

And Razer blade 15 with RTX 2070 MAX Q which is PC is perfectly working at Atmos without any issue.

So this is definitely XBOX SERIES X ISSUE!!!!

I have also had these issues with my xbox one. The input delay is similar to Vsync on the PC which waits for the TV or monitor to be ready before the GPU sends another frame to it. Most TVs only support 60hz input (60fps). On top of this, almost all TVs
have input delay whether it's 8ms, or 150ms. I guarantee it's not your controller - it would skip or not respond at all if it didn't have a good connection. The bluetooth controller input delay is so miniscual (1-5ms) you would not notice. The only way to
get a more precise feel is to switch TVs unfortunately....disadvantages of consoles I guess :/

Go here and look up your tv model to see where it's rated. http://www.hdtvtest.co.uk/news/input-lag

You could stream on mixer through your xbox and then you could put your own stream up on your laptop but there will be a 2 second delay with the control inputs, if you're playing a slow game it should work fine though.
