FPS problem in chrome when plugging in TV

[Ashleyyyy]

so basically, if i wanna watch a movie i plug my laptop into my TV. but when i do that, any video i play back in Chrome is very stuttery until i close chrome and relaunch it. 

 

my laptop's specs:

7700HQ

16GB Ram

GTX 1060

1080p 120hz screen

 

my TV is an ancient Philips dumb tv, 1080p 60hz. 

when i plug the TV in the laptop is configured to disable the internal screen, because i control the laptop from my couch using a phone app. 

 

is this issue a Chrome bug, Windows issue, etc? what can i do to fix it? it's very annoying having to re-open Chrome all the time.
