Hercules Prophet 4500 64MB

I recently installed a Hercules Prophet 4500 64MB in a P3 1GHz running on an Intel i815 chipset with 256MB PC133 RAM running Win ME. This machine is a Compaq Deskpro EN so I don't have a mainboard type. The general performance on the card is great with the exception that it seems to lose sync with every monitor I've tried at 800x600. I've used a Viewsonic E790, Compaq P1100, and Sony CPD-200ES. All of these monitors have the correct .inf from the manufacturer installed. I have tried every revision of the Kyro II driver I can find (currently running newest 7.114 from Hercules). Only way this runs is if I manually set the monitor to a standard 1024x768 SVGA in Windows with a refresh of 72hz. Has anyone else seen this and if so, do you know of a solution? The card has has also done this in my Athlon 900MHz on an Asus A7V-133 running VIA 4in1 4.32 and the same monitors, again with WinME. Thanks.

I got exactly the same problem.I just installed it on an ASUS CUSL2-C(P3 800)and when switching resolutions,eg. from a 640x480 game to desktop,the monitor 'loses'its screen adhustment.
I installed the latest 7.114 drivers and in terms of 3D-gaming/2D performance the card works excellent.
Any idea,or anyone that countered a similar situation?

Also it seems,that this happens on 815 platforms...!?

Look around in the properties and see if there is a Vertical Sync property. Disable that and it might help. What exactly do you mean it has a sync problem? Like there is screen tearing?

I think I know what you mean, I think? You mean every time you come out of a game or an application the screen shifts, right? or left. If that's the case, what you have done is the proper work around as long as you don't hear any funny noises coming from your monitor or it flickering mildly. I would see how the "optimal" refresh rate for the adapter works though.

If you mean that you are having graphic tearing or graphic abnormalities during gameplay, make sure you're not over clocking your video card or that it's set at the proper clock speed.

What you stated above has happened many a time to me while setting up some systems with certain video cards /drivers and monitors, some monitors just don't seem to like the drivers some video cards are using. Making it so no matter how hard you try to center the screen, it always seems to go off center after running a grapics application / game that uses a different resolution than the desktop.

Hope this helped some.

The screen isn't tearing. The monitor is completley losing sync with the card and goes into a suspsend mode because it cannot understand the video signal being sent to it.
