Display blurry when I drop to 1280x1024. Please help.

[Paradigm]

This should be my last post about computer issues. I'd like to thank those of you who have offered help, particularly Astroglide. I put in my new HD and this thing is blazing fast. There is one issue. I have installed all of my hardware drivers, but it defaults my laptop resolution at 1600x1200. That's just too damn small for my eyes. When I try to change the resolution to 1280x1024, it gets blurry.

I called Dell Tech Support (I have an Inspiron 5150) to ask about this problem. It was the case on the latest HD I installed as well. He asked if I installed the chipset drivers first, and I said no. So, I reformatted the HD (I know, it was a bit much, but this whole thing seemed unusual) and reinstalled the Intel Chipset drivers first, but the video resolution still won't switch to anything lower than 1600x1200 without being blurry.

Can anybody help? Please? I'm truly appreciative of everybody's help.
