Well, I bought the monitor after XP was out, but the drivers are for 2000, so....
Anyway, it's working at 75Hz (I rebooted a couple times, and used various utilities to verify that). It's not 85Hz like I wanted, but it's better than the 60Hz I had before 
Thanks for the help. |

The video card drivers are only half of the pie, you need both the video card AND monitor drivers installed to see all possible resolutions/refresh rates. They are not required for windows to work but they are required if you want windows to function in a way that is specific to your monitor, like listing the correct refresh rates. Don't just use the defaulkt drivers on the floopy. Check on the net for recent driver updates for the monitor. If both video card and monitor drivers are up to date, you may just have to do it manually, as you have been doing before.
There aren't more recent drivers for the monitor -- I checked.
My monitor's line has been discontinued since shortly after I bought it, and they never updated the drivers for it after that.
Anyway, the problem seems to be that Windows isn't correctly detecting the maximum vertical refresh rate. It should be 150Hz instead of the 120Hz that Windows is detecting... I'll try to force Windows to use the proper setting there, and see if that fixes it.
EDIT: Well, it'll do 75Hz now (85Hz still won't work, but I can live with that). I still have to leave the "List only modes that this monitor supports" box unchecked though  |

well, then...just override it after all, windows is written for general use for the average user and many users don't care what the refresh rate of the monitor is. it is just game players and computer geeks who know what the refresh rate means who care about it
anyways, just override, i don't think there is anything else you can do... |

what about the modes less than that? you know, the scale isn't continuous to use a reference from math. there are gaps in resolution support. However, that probably isn't the case so maybe you don't have the latest drivers?
I know I don't have "the latest" drivers for my video card. The 4.6 drivers are the latest (4.5 was the last release, and since 4.6 doesn't solve any problems I have, or give me better performance, I haven't upgraded).
And yes, I know the scale isn't continuous. I was stating maximums, not intermediates.
Anyway, both my monitor and my video card support 1600x1200@85Hz (I've checked the docs for both of them), but WinXP won't let me use a refresh rate higher than 70Hz. |

Yes, I've installed the drivers for the graphics card, and for the monitor.
Cat 4.5, and the drivers that came on a floppy with the monitor. |

Oops, I forgot to mention my video card, lol.
It's a Radeon 9700 Pro... it supports modes this monitor has no chance of displaying.

I've got a Hansol 920P 19" CRT monitor. I *know* that this monitor supports 75Hz and 85Hz refresh rates at 1600x1200, but WinXP won't let me use them unless I uncheck the "Hide modes that this monitor cannot support" box. Does anyone know a way to get around that? |
