U2410, two inputs and sharpening problem

This issue is a little hard to explain, but I'll try.

I'm using the U2410 with two laptops. One of them uses the DVI input, and the other uses HDMI. The laptop using HDMI needs the monitor sharpening set to 0 for a clear picture. The laptop using DVI needs the sharpening set to 50.

When switching between inputs, the sharpening value (either 0 or 50) is also supposed to switch. However, this is not the case. Although the numerical value for the sharpening changes correctly, the actual sharpening is not changed, and an unclear picture is the result.

The (annoying) solution, is to go through the monitor menu and increase the sharpening by 1, and then back down 1. This needs to be done each time I go from one laptop to the other.

Is there a better solution to this problem?
