I have encountered a problem recently: I plug in my computer to my TV with HDMI and suddenly any game will play at snail speed. Like ridiculously slow.
I have tried both of my TVs, lowered the games graphics to the lowest possible, have the games only show on the TV screen and tried matching the screen resolution on the game with the monitor. But nothing seems to make it much better.
As soon as I use the laptop alone the games work smoothly as usual. So, what causes it to lag via the TVs?
