Your question is a little unclear. Are you having to lower your resolution to play smoothly? If you can't play smoothly at your laptops resolution, going to a TV with higher resolution will be worse.
But, if you're saying you just want to play at a higher resolution and your laptop has smooth game play, then you can try using a TV as an external display to enjoy a higher resolution picture.
I have to reduce my resolution to play games and i'd like to find a way to increase it.
