Display detected by PNP wrong

I have a Westinghouse 22"lcd (LCM-22w3) that is detected by pnp as an Acer 17" (AL1714). This screws up the native resolution on the 22" and I have to force it to 1680x1050 after every boot up. I have tried this monitor on XP and Win7 (dual boot on separate HD) (a dell E510 w/bios updated) and get the same results. I also tried it on a Toshiba laptop (XP); again pnp detecting it as an Acer. There are no drivers for the monitor from westinghouse because it's pnp. I have updated XP to all the latest updates and also my graphic card (ATI radeon) to the latest drivers. Westinghouse says problem is a Microsoft glitch. Microsoft says they can fix it gaurenteed for 1 yr for $140, I told them I'd get a new monitor. Anyone know where the problem lies.

ATI radeon X300/X500/X1050 with cc panel latest version 10.2
Interesting that other post had a similar problem. I can force native resolution as i stated in original post, but when i reboot it goes back to the 17" resolution. The laptop which also sees the monitor as an Acer just has a basic onboard graphic chip, so I don't think it's the graphics card. I found a referance to the acer AL1714 monitor in the registry but it can't be deleted (saving first for future replacement) even in safe mode. Going to check laptop for similar reg line.
I updated to CCC yesterday so it should be the latest, but I'll recheck

I downloaded a program called Powerstrip from http://www.entechtaiwan.com/
that let me edit and save the edid information. My computer still sees the 22" as the 17" but I was able to edit the info (in options/monitor information) so that the native resolution is correct for a 22" every time i boot up, which solved my problem.

Open power strip, it shows up in the task bar. Open options/ monitor information.
On the bottom left side below Display Parameters, under option, expand that box that says "Read data from registry". Select "write custom monitor driver". Follow instuctions that pop up. Change monitor driver from Control Panel/ System /Hardware /Device Manager to the new .inf driver file you created. May have to restart computer for change to take.

It's been awhile since I used powerstrip but try going to Display profies/ configure/ advanced timing options/ custom resolutions. Play around with different setting of the resolution you want. sometimes it would work sometimes not.
I'll respond better when I have time to review what I use to do. Like I said It's been awhile.

1st have you updated drivers for your video card, that will solve this sometimes. Or possibly your bios if your using onboard video. Also check your video cable, some older VGA cables didn't use all 15 pins and sometime I've found a DVI cable will work but a vga cable will have problems. See last sentence.
In power strip, after you go to display profile and then configure, you shoud see a window that has your video card on the top line/window. below this is two columns "color depth" and "options" on the left, "resolution" and "refresh rate" on the right.
Under the "refresh rate" click the "Advanced timing options" bar. On the bottom right of the window that comes up click the "custom resolution" bar. On the window that comes up click on the resolution you want (look through the whole list cause the same resolutions may be repeated. For the 22" lcd you can use 1680 x 1050 (LCD) or 60Hz. After you clicked on the resolution, on the bottom right click the, "Add new resolution" bar.

This should make the change; restart may be required. Then open windows "display properties"/"settings" and hopefully you can change the resolution to 1680x1050 on the slider bar. if not click the advanced bar, and the monitor tab, and uncheck the box that says "Hide modes that this monitor cannot display". ( actually try this first before messing with powerstrip.

tried list all modes(didn'd have anything higher than 1280x1024) , the "Hide modes that this monitor cannot display" only applies to refresh rates............. and 1680x1050 [LCD] or 60 Hertz didnt show up on the slider. so neither works, i got a DVI adapter to plugin to my monitor but unfortunately i got DVI-I isntead of DVI-D(the one my monitor has)

Edit: Oh and i have updated my drivers, it changed resolution to 1280x1024 when my brother accidently pulled the power cord out of the wall
