1 time, when I was modifying my monitor for my driver I unchecked hide modes that this monitor cannot display then Halo could run 1280 x 1024 @ 120 Hz.

Then I reset my PC and checked my driver and realized the hide modes option was grayed. I couldn't modify it, but it was still off.

Then the next day I turned on my PC and realized that the hide modes is tunable again.

It was unchecked, but when I opened up Halo, Refresh rate was at 60 Hz!

I increased it, but the highest it went was 75 Hz.

How do I Gray out the hide modes option or have my 120 Hz. back?!
