Question about lcd native resolution and game quality

I've been trying to decide whether to go for the 1440x900 or the 1900x1200 screen option for an inspiron 17 inch laptop. Is it true that the further away you play from a screen's native resolution, the fuzzier the picture becomes? To me it seems that 1900x1200 is a ridiculously huge res for a 17 inch monitor and a laptop video card would have a hard time running new games at 1900x1200. Would there be a significant difference in quality running a 1440x900 res game on it's native res vs. running that res from a 1900x1200 monitor? Thanks for the help.

 

Bar the upcoming 8800 series cards just about every card in the market right now would struggle to play games at 1900 native resolution with settings turned up. From what I've read on the forum native resolution gaming (doesn't matter what the resolution is) will be sharper than resizing. Difference between 1900 and 1440 would probably be how much you can fit onto the screen at any one time.

I chose a 1680 native resolution since I like watching movies on my laptop and thus appreciate having more room, others will say that hardcore gamers should stick to as low a native resolution as possible which your card can comfortably handle for best results.

 

It really is matter of personal preference and games you play, some games look ok some games don't outside the native res. I play some new games at 1024x640 and my screen is 1440x900 and they look nice. But I think strategy games with small units in screen look bad.
