Weird Latency / Lag without FPS Drops?

Update: It was the dock. I tried running it to the TV directly from the laptop's HDMI and there's no issue.

I still don't know why a dock would cause that, though.

Hi, I noticed a problem with my laptop last night where in games there seems to be up to about a 1.5 second delay in game, but there are no FPS drops. Also, the mouse moves fine in menus, but it lags before options are highlighted when moused over.

 

Laptop specs:

i7, 3080, 1440p 144hz screen refresh, windows 11

 

I'm using a USB-C doc to output video to a 1080p TV I'm using as a monitor for schoolwork. I've locked FPS at 60 b/c that's the refresh rate of the TV.

(I know, I should use the built in screen, but these have just been casual gaming sessions between lessons)

I have a secondary monitor (1080p 60hz) mirroring my laptop built in screen. When I run the game on the built in screen, there is no lag, but I can still see it on the monitor that is mirroring it.

 

Again, the mouse moves without latency, but the menu options lag before highlighting.

 

Maybe it's the doc? But I don't know why it wouldn't effect the mouse if that was the case.

 

Honestly I'm at a loss. Any help would be greatly appreciated, if for nothing other than satisfying curiosity.

The TV, does the situation improve when you switch it to game mode?

Old TV-s have slow panels and have a lot of input delay due to signal processing done.

There isn't a game mode I can find, but I wouldn't think the other monitor would do it too if that was the case, and also I can see the mouse move around on the TV fine, but the menu options don't highlight right away. That makes me think it's not an issue with signal processing, but I could be wrong

Also, I've been using this same setup for a few months, but this is a new problem
