It's 1280x800. It looks very similar in quality to the original. Swapping it didn't immediately fix mine. After I upgraded.to BIOS A15 and the NVS 3100M driver from NVidia version 326.19, I no longer have the issue. I have no idea what combination of things did it, and will just accept the fact that it works with a smile.
It's amazing how much it used to bother me. I get pleasantly surprised, every time my display powers up and doesn't drive me crazy.
