Why does connecting a laptop to a TV via HDMI cause a framerate drop?

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?

Best Answer

The most common problem is that your TV needs to be in 'Game Mode' to enable the proper refresh rate. TVs by default add a lot of processing of the image being presented. You don't notice it when watching TV, but it can cause 'input lag' when playing games.

The FPS is not affected by the type of screen you are playing, although playing on TVs is not ideal, since TVs usually dont focuson improving response times, which generates a higher delay between the moment you give a command (such as move the mouse) and the moment you see it happen on the screen.

Does playing on a TV affect FPS?

Nope. It isn't the size of the screen that matters, it's the amount of pixels. So the TV, even though larger, likely still has the same amount of pixels as a 1080p monitor.
