the monitor works, but it's listed as a default monitor, and vgasave is on, plus the refresh rate seems very low (although i have no trouble with high resolutions or colour depths). this is why i think my new Geforce2 MX400 AGP card won't work. Any other reason, save for a defective card, seems impossible. My monitor is an Acerview 56c, and acer's site offers me no help with drivers. But shouldn't there be an option somewhere to update my monitor drivers? the device manager doesn't even show a heading called Monitors. any help would be appreciated, as i have no desire to take my computer into a shop.

First, what drivers are you using for your video card? Second, there is a wonderful free program called NVrefresh tool www.nvrt.net that will take care of refresh problems.

i've tried the drivers that came with my card, plus nvidia's drivers, and recent drivers from the card manufacturer's site (www.gainward.com). i don't think the problem is with the card or the drivers, but rather the fact that windows uses vgasave as the monitor driver. all of this is just a slightly educated guess, but i really can't think of anything other than proper monitor drivers (or at least something that's NOT vgasave). i could of course try it in win98, which has no problem detecting my monitor as what it is, but alas, i don't have the install cd handy.

I just got done looking and your monitor is listed under the other for the drivers, I opend the inf file and at the very bottom you monitor is listed 7256c= "Acer 56c" Here is a link to the international site you need http://www.benq.com.tw/global/service/crt/drivers.htm the site is bencQ now they are doing the monitors for the acer comps. Good luck and let me know if this helps.

Did you right click on the screen and open Properties ? Click on the Settings tab. You can adjust the resolution and color bit rate there. Click on the Advanced button/Adapter tab. Click on List all modes button to adjust refresh rate. At least 75 hertz should be fine. There is a Monitor tab where you can install another driver if you want, but my Windows XP driver works just fine.

thanks for the suggestions, i found some old thread on this site, and tried setting 'set pci to vga' on in BIOS (or something to that sense), and my geforce2 started working, so it wasn't a monitor problem.
