Many thanks for these very helpful observations. You are quite right of course, all those Windows 98 statements are out-of-date and it is pointless to pursue that line of thinking. I have not given up yet. I have asked ATI to confirm that extended display is possible with Windoes 98 and a Radeon 9250. So far they have asked me to reload the drivers which I have done of course without success. Thanks again for your continued interest in this problem.

Hi,thanks for asking. No, I cannot drag the secondary windows over to monitor 2. It is simply a case of whatever I see on Monitor 1, I also see on Monitor 2. This applies right from the word go, during boot up and everything.One interesting point is that if I swap the primary and secondary monitor then both screens show nothing. A right mouse click leads to a display of the usual options ArrangeIconsBy and Properties but as before this displayed on both screens.Another interesting point is that when I look at the memory allocation for Display Adaptor (Radeon) I see memory range and interupt (11) but for the Display Adaptor (Radeon Secondary) while there is a memory range there is no IRQ and no I/O range.

Hi Peter,Your second point is normal. I just checked my set-up.Hope this helps,Jimhttp://www.hifisim.com/Active Sky V6 Development TeamActive Sky V6 Proud SupporterHiFi Beta TeamRadar Contact Supporter

Thanks for that. I can cross that off my list.But it has occurred to me that this whole problem has nothing to do with Windows at all because both monitors are showing identical displays from boot up onwards. Perhaps this means that the problem lies in the BIOS settings. I have tried changing every setting that has something obvious to do with VGA/AGP etc but nothing helps, both monitors light up like twins from the word go.I have checked the spec of the Radeon 9250 card. Under features it says "Dual integrated display controllers to drive two displays simultaneously with independent resolutions and refresh rates". That seems pretty clear to me. So why do they both display like twins??? One should be blank at start up, don't you think? That's what happens to my set-up at work.

Have a look at these links and see do you have this ATI software installed. http://www.ati.com/products/Hydravision/usesgaming.htmlhttp://www.ati.com/products/Hydravision/faq.htmlhttp://www.ati.com/products/Hydravision/index.htmlIt may go back only to WinMe but often Me stuff will work on '98P.

I forgot to mention to ignore the "What products support Hydravision

Thanks for reminding about Hydravision. I have just reloaded it to see whether it might help but it does not. It relies on utilising the Control Panel so it really gets me no further. The more I think about it the more I think the problem is deeper than Windows or controllers. The fact that both monitors mirror one another from the start (boot up) seems key to me. It is almost as thought the outputs are hard-wired together. Physical inspection confirms that this is not the case however. I'd like to try the card on another mother board to see what happens. That might tell me something. I do have the entire dump of ChipInfo if anyone can interpret all the data about the board and chipsets.Thanks again. Peter
