Montior Resolution vs GPU resolution?

[RobHimself]

Trying to calibrate my monitor using lagom.nl/lcd-test

It is telling me that my browser is reporting the video card settings as 1466x916 with 24 bits of true color.

However, when I go into display settings through windows, I have the native resolution of 1680 x 1050 with 32 bit color selected.

Can anyone tell me why these two resolutions do not match, and what I need to fix?

Monitor is a Samsung SyncMaster T220HD
GPU- AMD HIS 6950 2GB

Thanks!

You have no problem to fix. That web page tells you that the screen properties as reported by your browser may not be accurate. I just tried it with Firefox and it was accurate, but other browsers may give different results.
