What is the physical hardware risk of increasing refresh rate beyond Win 2k's recommendations?

I have:
-Prophet 4500 64MB, KYRO II Video Card (Maximum Refresh @ 1600x1200 is up to 95 Hz according to Hercules)
-Compaq P900 19" Trinitron(Maximum Refresh @ 1600x1200 is up to 85 Hz (Graphic Preset Mode) according to Compaq)

Currently, Windows 2000 SP2 will only allow me to run this setup at 1600x1200 @ 75 Hz, but I should be able to run this system at 1600x1200 @ 85 Hz without trouble. The highest refresh rate that Windows 2000 will allow me to select is 75 Hz. My question is this: How great a risk to my physical hardware do I pose if I were to edit the registry directly and change the settings to 1600x1200 @ 85 Hz?

Note: I have installed all the latest drivers for both devices

Problem Solved using Powerstrip program, I think the video card was what was limiting the OS. Thanks for everyone's comments

you're not going over any spec, it might be that win2K reads the device information wrong, but setting your monitor at 85 hz shouldnt be any problem at all, because both the 3Dcard an the monitor can handle it ...

IF u ever want to go over the specifications of your monitor, the results vary depending on teh age of your monitor, modern screens just display a blank screen, while older ones (without protection circuitry, will most likely will overheat and possibly even sustain (lethal) damage

u can never surpass the limits of the 3Dcard concerning the refresh rate of the output, that is a hardware limit ...

Is the monitor accurately identified? Perhaps there is an updated INF from Compaq which will allow the OS to see the correct specs.
