Youtube frame drop with monitor/TV duplicated

[MYSTICmayonaise]

I am having an odd and annoying issue.

 

Youtube videos are dropping alot of frames while in fullscreen mode on my PC, like 1/2 to 2/3 of the frames are dropped (according to the "stats for nerds" on youtube.

 

I have 2 monitors and a TV, my PC is more or less a media pc so i like to have the TV to watch videos, movies, or couch game, and my TV is where my PC's audio is running through, so having it not connected is an issue.

 

My right monitor and TV are duplicated, I.E. showing the same images on each screen, and the left monitor is normal.

The panels are all 60hz

this has been happening for ages

I have tried reinstalling drivers, Chrome, and anything else i can think of that might have caused issues.

 

but now it seems that the screen duplication is the only reason why i am losing so many frames while watching youtube videos, and its only while videos are fullscreen on the right monitor/and tv

if videos are played fullscreen on the left monitor, no drops

i also tested having both monitors duplicated, which caused the same issues

and having no screens duplicated, videos played in full screen just fine on all screens when duplication was off.

 

 

any help for this odd problem would be welcome, Ive been dealing with it for months and its driving me crazy.

Might be caused by mirroring the monitor with the TV. I know for a fact that TVs can have much higher refresh rates but are much slower than computer monitors in terms of input latency. Which leads me to believe mirroring a screen between a monitor and TV isn't going to be the best idea.

It happens when mirroring just the monitors as well though, which are identical displays 

 

And the refresh rates are the same, and will the TV does have a bit of latency compared to the monitor, that shouldn't cause videos to lose 2/3 of frames.

I also am running into this EXACT issue as well. I decided to make a post about it on the Google Chrome reddit page. Hopefully we can find a solution to this problem.
