Are there better laptop screen resolutions for gaming on a PC?

If your laptop is primarily for gaming, I would get the highest resolution screen you can afford with at least a resolution of 1920x1080, with the performance that can back up 1920x1080 at native. If your budget doesn't permit that price/screen/performance matrix consider a more affordable laptop with a 1366x768 native screen.

If your laptop is for more than just gaming, I would get at least a 1920x1080 screen. If the laptop can't handle the games at native then run your games at lower resolution. This has the effect of a bit of blur in the upscale to native, but you also don't sacrifice your productivity with non-gaming tasks.

I would suggest reviewing all of the different opinions that have collected on this question to get well rounded advice.

I think 1440x900 is a good size for a monitor. It provides a high quality resolution whilst not being too large that the graphics card, which is likely to be less powerful that a desktop version, won't get stressed out.

My concern with high resolution screens (~1920x1080+) is that the graphics cards will not being able to provide enough grunt and you will have to degrade the overall graphics quality to get a stable framerate.
