Unless you have specifically set a refresh rate for each resolution you may use in your graphics setup in Win, then by changing the res in AH it will use the default optimal refresh for that res in AH.
To adjust it you have to first go to windows graphics setup and change windows to the resolution you wish to play at. Now set the refresh rate you wish to use at that resolution. After accepting this res thereby saving the info you can then switch your desktop back to your normal res.
When you use AH next it will automatically use the refresh rate that you previously saved at your chosen 1600 resolution.
You can preset refresh rates for all available resolutions doing this, win will remember them all.
