Does connecting your laptop to TV via HDMI decrease gaming performance

pcperformance

I have a laptop I use to game, its not a high-end one. My resolution is 1366×768, I'm thinking of getting a HDMI cable to try out gaming on the TV.

My card is an ATI Mobility Radeon 5470 HD, and it supports eyefinity, when I use dual monitors to game it reduces the framerate by 3-5 FPS. Since my TV is a 46-Inch 1080p 120Hz LED HDTV, I'm wondering if it would take a major hit on my laptop?

In your situation I would connect the TV to the lappy and use just the TV as a screen; here's why:

  1. The 100Hz refresh rate combined with the LED is going to make the refresh rate the same (or comparable) as the lappy.
  2. The resolution is higher.
  3. And you don't say the size of the laptop screen, but I assume it's less than 46 inches. So it'll be probably double or triple the screen size.

It's going to look bigger and higher res on the TV and the refresh rate shouldn't be noticeable to human eyes.

I have a similar set up: 27" FHD screen with 14" lappy. I recommend external keyboard and gaming grade mouse (preferably wireless).
